USER GUIDE FEATURES

The Octopus 3000 User Guide is presented infive chapters: Introduction, Installation,Programming, Operation and Maintenance,and Troubleshooting.

In Chapter 1, we provide a basic overview of

the Octopus 3000 and its capabilities. Werecommend that all users review this infor-

mation before proceeding with Chapter 2,Installation and Software Programming.

This User Guide includes several quickreference features, including Notes, Cautionsand a Quick Reference Menu Map.

QUICK REFERENCE MENU MAP

The laminated Menu Map included with your

Octopus 3000 summarizes the H2O/S soft-ware menu structure. Post it in a convenientspot for quick reference. For more detailedmenu maps, refer to Appendix A.

MONITORING CAPABILITY

The Standard Octopus 3000 software providesfor monitoring, control, and alarm capabili-ties. The four water quality parametersmonitored are:

Conductivity

Temperature

pH

ORP

In addition to the four parameters theOctopus 3000 also provides an aux. inputwhich can be configured to provide a digitalinput for power failure detection, or waterlevel alarming.

Probes connected to the bottom of theOctopus 3000 gather information and relay itto the Octopus 3000 for processing and

display on the screen.

Introduction

Figure 1.2 Parameter Status Lights

The Octopus 3000 is programmed using amembrane keypad on the face of the unit.Directional arrows on the keypad are used tomove horizontally across a given menu level.The Enter key is used to move down themenu map or to make a selection.

Once in the submenus, if there is no activityfor ten minutes in most menus, the OctopusLCD display window will return to theCurrent Status Display. Settings entered upto that time will be saved. When not inprogramming mode, current status informa-

tion gathered by the probes is shown on theOctopus LCD Display Window.

FLASH MEMORY ARCHITECTURE

A key feature of the Octopus 3000 is that it is

designed using FLASH memory and a special

application embedded in the Octopus 3000

called abootst rap loader. When the loader is

used in conjunction with other PC software

offered by Aquadyne, routine updates to the

Octopus 3000 H2O/S software can be easily

accomplished. Refer to Appendix D for

instructions on upgrading the H2O/S soft-ware in the Octopus 3000. Additional

Information about the current revision level

of the H2O/S software, the availability of

AquaWeb for Windows 95, and other techni-

cal details about the Octopus 3000 can be

Infrared Printer Port

The infrared printer port located at the bot-

tom left of the face of the Octopus 3000 is

standard. This port provides access for the

optional infrared data-log reporting feature.

Using the Infrared Printer (optional) data

collected by the Octopus 3000 can be printed

out in a variety of formats, including the

current data, the high and low points of data

collected within the last 24 hours, 48 hours,

or 1 week. Temperature, pH, and ORP canbe graphed. Conductivity will be added in a

future release of H2O/S software

Powering the OCTOPUS 3000

Primary power for the Octopus is provided by

an A/C wall-mount transformer. A UL, CSA

or CE approved transformer rated for the

correct input voltage (110V or 220V) is used

to power the Octopus. The output voltage to

the Octopus must be 9V AC.

The Octopus design incorporates FLASH

Memory, RAM, and a battery backed-up real-

time clock. Should power be lost, none of the

parameter setpoints, or configuration datawill be lost. However, during a power failure,

data in the datalog will be erased.

Backup power is provided by either of two

methods:

An optional 9-Volt backup battery packspecially designed by Aquadyne.

An optional UPS Backup Power System(Uninterrupted Power Supply). (The A/Cwall-mount transformer is plugged intothis system.)

The backup battery-pack is an inexpensivemeans of providing about 45 minutes of

backup power during a power failure. While

operating from the battery pack, the Octopus

Introduction

Your Octopus is a precisionlaboratory instrument thatcould be damaged by unex-pected power surges or fluctua-tions.

The use of a quality surgeprotection device is highlyrecommended, and is requiredto preserve your warranty.However, DO NOT USE a surgesuppressor between an Octo-pus power line interface and acontrol module.

CAUTION

The proper and reliable function-ing of the Octopus and the X-10control system is dependent onthe proper installation of theOctopus, the X-10 Power LineInterface, and each ControlModule. Other electrical devices,such as motors, ballasts, anddimmer switches produce electri-cal interference that may affectX-10 signaling. Refer to Chapter

5, Peripheral Device Trouble-shooting, for further details.

CAUTION

will continue to operate normally until thebattery is exhausted.

If a UPS system is used as a backup powersource, it may be purchased from Aquadyne.A UPS backup is a good idea if you requiremore than 45 minutes of backup power, or ifyou wish to backup other critical peripheralor communications equipment such as apump, a bio-filter or a modem for example.

Note however, that the duration of backup ofthe UPS is reduced by the addition of suchequipment.

Control Capability

H2O/S software is used to program the

Octopus 3000 and give it the capability for

parameter control as well as monitoring.

With the purchase of the optional X-10

power line interface and one or more control

modules, a wide variety of monitoring and

control features are automatically activated.

The Octopus 3000 control system has six basic

components, as shown in Figure 1.4:

(Note: The modem, the X-10 power lineinterface, and the control modules areoptions.)

Control Using X-10 Management

The probes gather information and relay it tothe Octopus controller (Figure 1.4). Thecontroller then sends commands through the

X-10 power line interface to the controlmodules. The control modules receive signals

from the Octopus via the X-10 power line

Introduction

interface turning the devices on or off asneeded. Each device that the Octopuscontrols, such as a heater or chiller, has itsown control module. As many as 256 ad-dresses and a variety of devices can becontrolled by the Octopus, using X-10 controlmodules

The Octopus 3000 incorporates severalmechanisms to protect your aquatic environ-ment from controller failure. For example,the controller is engineered to overcomeproblems associated with power fluctuations

through the periodic re-sending of controlmodule commands to make sure that a X-10control is latched in the correct state.

In addition to controlling peripheral equip-ment to maintain water quality, the H

2O/S

software supports other optional featuresthat can be enabled on the control menus:

A Lighting System

System Hold Management

A WaveMaker System

An Alarm System

Each of these features is described in follow-ing sections.

Introduction

Example Lighting Scheme24-hour period. The Octopus 3000 comesstandard with 4-channel lighting software. Aoptional 16 channel system is available as anoption.

With separate lighting timers, there is a highdegree of flexibility in setting up your lightingsystem. For example, in your application youmay wish to use a combination of metalhalide, fluorescent, and incandescent light-ing. And each lighting system may require adedicated ON and OFF time. The Octopus3000 lighting system can manage these and

other varied timing needs under softwarecontrol. (Figure 1.5).

System Hold

The H2O/S system hold software is a featuredesigned to aid in the feeding of fish andinvertebrates. When the Octopus controller isput into feed mode, all systems, except theLighting and WaveMaker systems, are shutdown for a period of time selected by the user.At the end of the specified time (up to 60minutes) all systems are turned back on andwill restart within 5 minutes. If desired, the

system hold option may be turned off bysetting the feed time to 0 minutes. TheOctopus controller will then no longerprompt you to enter the system hold mode.

WaveMaker System

The H2O/S Dual Channel WaveMakersoftware feature allows the Octopus 3000 tocontrol two independent wave or surgegeneration systems. Each system supportstwo pumps which are driven by ControlModules. The cycle time for each pump isselected by the user, from 1-999 minutes (over

16 hours).

Lighting System

(4-Channel or Optional 16-Channel)

The lighting control feature allows theOctopus 3000 to control your system lighting.The lighting system will support up to 16

independent lighting times per 24 hours.Each channel has one ON and OFF time per

Figure 1.5 Example Lighting Scheme

Timer 1 is for the fluorescent lamps.These lamps are the first lights to comeon in the morning and the last to go offlate at night.

Timer 2 is for the metal halide lamps.To approximate the sun rising, theselamps come on in the late morning andgo off in the late afternoon.

Timer 3 is for an additional halide

lamp. This lamp will come on for aboutone to two hours at noon to simulatethe midday sun.

Timer 4 is for a red bulb during thenight to allow observation of nocturnalcreatures that come out when the lightsare out, and or moonlight simulation.

If you have the 16-channel LightingSystem and are not using all 16 chan-nels, you can use the additional chan-nels to control other devices.

Installing the Components

This Chapter will provide you with simplestep-by-step instructions to lead you throughthe installation process. But beforecontinuing...

STOPREAD THIS FIRST

DO NOT ALLOW CONTROLLERTO GET WET!

Your Octopus 3000 controller can belocated in any dry location. The controlleris not waterproof and cannot be sub-merged, permitted to get wet or exposedto high humidity. To avoid splashing theunit, install it properly as described inthis chapter.

AVOID DANGEROUSOPERATING CONDITIONS

Do not operate the Octopus controllerunder any of the following conditions:

With wet hands.

If you are standing in water.

If the AquaNode Controller is wet.

If there is salt creep on the box.

KEEP pH AND ORP PROBE TIPSWET AT ALL TIMES

To prevent loss of accuracy in the pH andORP probes, be sure to keep the tips wetat all times. NOTE: Do not completelysubmerge probes. Refer to probe installa-tion procedures (Step 2) in this chapterfor more information.

INSTALL ALL ELECTRICALCORDS CORRECTLY

Always take care when using electricityaround water. To prevent water from

running down the cord of an aquariumdevice, always use a drip loop as shownin Figure 2.1. To create a drip loop, makesure that the cord extends below theoutlet so that any runoff will not enterthe outlet or the device. Also, the Octopuscontroller and ALL other aquatic environ-ment devices should be plugged into aGFCI outlet.

If you are n ot famil iar with ins tal lation

of electrical equipment, i t is strongly

recom me nded that you hire a l i censed

electrician.

CAUTION


21/113

CHAPTER2: INSTALLINGTHECOMPONENTS 2-3


Figure 2.1 Protective Drip Loop and GFCI Outlet

In addition to a surge suppressor, a Ground Fault Circuit Inter-rupter (GFCI) should be part of you installation. A GFCI is a sensi-tive device which immediately cuts off the electricity flow when anelectric current leak is detected. All devices t hat are part of t heOctopus 3 00 0 s ystem should be conn ecte d to a GFCI protect ed

circuit. If you do not have one installed already, you should pur-chase one. They are inexpensive and are available at any electronicsor hardware store. Dont wait, a GFCI can save your life!

CAUTION


22/113



INSTALLING THE COMPONENTS

There are two basic parts to installing theOctopus 3000 controller:

Installing the Octopus hardware andadditional components(Chapter 2, Steps 1 through 8).

Programming the Octopus (H2O/S)

software(Chapter 3, Steps 9 through 25).

Not all systems require the same installation

steps. The steps required for each individualsystem will depend on:

Whether the system is monitoring onlyor monitoring and control.

Which optional components are in-cluded in the system.

Table 2.1 indicates which componentsinstallation procedures your system requires.For example, for Monitoring Only systems,only installation steps 1, 2, and 7 would berequired.

STEP 1MOUNT THE OCTOPUSCONTROLLER

The Octopus controller will need to beinstalled within 5 to 10 feet of the probes. Ifyou wish to place the controller beyond thestandard 10-foot length of the probe cables,additional cable extension are available in avariety of lengths through special order.

The controller comes with two mountinghangers for easy installation. Use the screwsprovided to attach the controller to the wall.

The ORDER OF INSTALLA-TION is important to success-ful startup and operation ofthe system. The X-10 ControlInterface, Satellite Modules,and Modem must be installedbefore the Octopus controlleris plugged in to ensure properinitialization of thesecomponents.

STEP 2INSTALL THE PROBES

Up to four probes can be installed as part ofthe Octopus 3000 system. Three of theprobes (temperature, pH, ORP) have the samebasic installation requirements. Theconductivity probe, requires specialinstallation procedures to ensure properoperation and accuracy.

In all cases, it is desirable to locate the probesaway from sources of electrical interferencesuch as UV sterilizers, florescent lighting,ballasts, pumps, etc.

PROBE UNPACKING

pH and ORP probe tipsmust be kept wet at alltimes. The probes should beinstalled immediately aftertheir tips are exposed to air.If probes are allowed to dry,they may be damaged andmay produce inaccuratereadings.

To prevent damage to the ORP probesensor, FIRST REMOVE THE TAPEOVER THE VENT SEAL on theprotective cap. Then remove theprotective cap.

Remove the protective caps from theremaining probes and install perStep 2 instructions.

OTHER CONSIDERATIONS

pH and ORP probes can require a

minimum of 48 hours to stabilizeafter installation. DO NOT ENABLEOCTOPUS CONTROL OF THESEPARAMETERS FOR 48 HOURS.

Be sure probes are plugged into thecorrect Octopus probe ports. If theyare plugged into the wrong ports, thesystem will not monitor properly.

Place temperature, pH, & ORP probeswithin 6 inches of each other.

The conductivity probe should belocated at least 18 away from thetemperature probe.

CAUTION

Note

The Octopus is a precision

instrument that has beendesigned to interface with high-quality laboratory grade probesmanufactured in the USA toAquadyne specifications. The useof other probes (especiallyinexpensive imported probes) notapproved by Aquadyne is notrecommended and will not besupported.

A genuine Aquadyne probe canbe identified easily by thepresence of date code stamped

on the top of the probe shaft.


24/113



4. Place the probes in the location selectedin Step 1. None of the probes can besubmersed. Mount the probes so thatthe top of the probe is above the waterline. The probes should be positioned sothat ONLY ABOUT HALF of the probeshaft is immersed in water.

Alternative Probe Locations

Select a probe installation that will allow thepH and ORP probes to be located within 6inches of the temperature probe.

Three possible probe installations are:

In-Filter Location Using Probe Mounts(Figure 2.2).

In-Filter Location Using a Float(Figure 2.3).

In-Line Location Using Tee-Fittings(Figure 2.4).

Figure 2.2 In-Filter Location Using Probe Mounts

Installing the Temperature, pH, andORP Probes

The four steps in probe installation are:

1. Select a location for the probes that willallow the pH and ORP probes to beplaced within 6-inches of the tempera-ture probe. (Alternatives are describedin this section). By placing the probesclose to each another, the Octopus isassured that the probes are not subjectto different electrical environments that

could affect their accuracy. Theconductivity probe is a special case andshould NOT be placed with the otherprobesif at all possible The diagrambelow shows the conductivity probeplaced in-line back to the pump.

2. Remove the vent seal on the ORP probeprotective cap, then remove all protec-tive caps.

3. Plug the probe connector cables intothe designated port at the bottom of theOctopus 3000 controller.

plumbing, it has been found to be a veryaccurate and safe way to place your probes.In-line placement will give accurate readingsbecause water is moving across the probe tipsat all times, and because algae growth on theprobe tips is minimized.

The probe is placed into a tee-fitting, asshown in Figure 2.4. You will need to providethe tee-fitting for this installation. Thediameter of the in-line portion of the teeshould be 1/2 inch (3/4 for conductivityprobe) regardless of whether you are using

laboratory or standard grade probes as theyare supplied from Aquadyne. Aquadyne offerstwo compression fittings for installation ofthe probes. Flow rates across the pH andORP probes should be limited to < 10 GPM.

Be sure to install water shut-off valves, asshown in Figure 2.6, to permit probe replace-ment. All fittings must be secured so there is nowater leakage.

It is important that the in-line probe extendno more than about 50% into the flowstream. If the probe protrudes too far into theflow stream it will interrupt flow and interferewith the accuracy of the probe readings.

In-Filter Location Using Probe MountsThemost common place for probe location is inthe filter. Installing probes in a filter or sumprequires that the probes be secured usingprobe mounts that attach to the back of thefilter so the probes are only half-immersed inthe water, (See Figure 2.2.) When placingyour probes, be sure that there is adequatewater flow over the probe tips at all times.The pH and ORP probes must be placedwithin 6 inches of the Temperature Probe.

In-Filter Location Using a FloatThe float

installation shown in Figure 2.3 keeps probesfrom being submerged (or drying out), and iseconomical to construct.

To construct a probe float, punch a hole(slightly smaller than the probe diameter)through a small piece of styrofoam. Be surethe probes are no further than 6 inchesapart. Insert the probes into the float, asshown in Figure 2.3.

In-Line Locat ion Using a Tee -FittingAlthough in-line probe placement is a littlemore difficult and requires some extra

Installing the Conductivity Probe

Installation of the conductivity probe issimilar to the installation of the pH, ORPand temperature probes discussed previously.

1. Select the proper probe location awayfrom the other probes.

2. Remove the probe protective cap.

3. Plug the probe connector cable into theconductivity port at the bottom of theOctopus 3000 controller.

4. Place the probe in the location selectedin Step 1.

Alternative Probe Locations

The conductivi ty probe must be located

away from the other three probes, and the

conductivi ty probe m ust be inst al led in a

control led volume environm ent cal led a

conductivi ty ce l l .(See Figure 2.5)

The conductivity cell provides the conductiv-ity probe with a controlled volume environ-ment. The conductivity cell is required to

achieve accurate conductivity readings. Itreduces the chances that the conductivityprobe will be affected by alternate ground(conductive) paths.

The conductivity probe can be installed ineither of two ways:

In-line, using a tee-fitting.

Off-line, using a Drip Cup.

In-Line Location

The in-line installation shown in Figure 2.6is the preferred installation method becausethe tee-fitting is a natural conductivity celland it provides the most accurate measure-ment environment.

The general procedure is the same as thatdescribed above for temperature, pH and ORPprobes. However, the conductivity cell, isutilized. Be sure that the installation providesthat about 10% of the probe protrudes intothe cell. Aquadyne provides a score-mark onall of its conductivity probes that guidesinstallation and assures proper insertiondepth.

If the conductivity probe is notinstalled in a conductivity cellor if the probe is exposed toelectrical interference frompumps, motors, or electricalballasts, unreliable readings

will result.

Off-Line Location

The Drip Cup installation is a secondoption for the conductivity probe installation.As illustrated in Figure 2.6, a portion ofwater from the pump discharge line isdiverted to a small cup-type arrangement.

The water flows in and out of the cup at arate of about 1 cup per minute.

In a drip cup installation, there is no com-pression fitting to control insertion depthyou must carefully position the probe so thatthe end of the probe is approximately 1 inchfrom the bottom of the cup.

Stabilization Period for Probes

After the probes are installed, there is aperiod of time required for each probe tostabilize in its new environment. The conduc-tivity probe will be the first to stabilize in only5 minutes, followed by the temperature probewhich requires about 10 to 15 minutes before

accurate readings are possible. The pH andORP probes will take considerably longer tostabilize. Their readings are much moresensitive. The pH probe will stabilize in about24 hours while the ORP probe may require 48hours.

STEP 3INSTALL DIGITAL INPUT

HARDWARE

Various system conditions, such as high orlow water levels, high or low pressures, flowfailure, or power failure can be detected andalarmed using digital input hardware. Thesedevices use a switch and relay that detect andalarm when an electrical circuit changes fromopen-circuit to closed-circuit position, or viceversa. This section provides instructions forinstalling a float switch (water level detec-tion) and a power fail detector.

Aquadyne offers digital input devices forwater levels, pressures, flow, and power faildetect.

Aquadyne offers an optional 8-pin connectorand wire that can be used to hook up amiscellaneous digital input.

Installing a Float Switch

A float switch consists of a stationary stemand a float that moves up and down with thewater level. When the float is in the raised

position, it is in the CLOSED position. Whenthe float is lowered, it is in the OPEN posi-tion.

Install the Float Switch in Tank or Filter

The float switch should be installed in thetank or filter at the desired level, according tothe manufacturers instructions. (Many floatswitches will require drilling into the tank atthe desired float location.) Be sure the floatis installed in the position shown in Figure2.7 (with the arrow on the side of the switch

pointing up).

Once the float switch has been installed inthe tank or filter, connect the 8-pin connec-tor to the bottom of the Octopus (in the 8-pin digital input port).

Installing the Power Fail Detector

A power fail detector is available from Aqua-dyne. This 9-volt wall mount device isconfigured with an 8-pin connector, as shownin Figure 2.8. Install the unit as follows:

1. Plug the 9-volt power detect switch into

a 110-V outlet.

2. Plug the 8-pin connector into thebottom of the Octopus. (At the 8-pinGeneral Input port.)

One Control module will be needed for eachperipheral device you want to control, asshown in Figure 2.9.

To install the Control module, simply plugthe module into a GFCI-protected electricaloutlet. Then plug the device to be controlled(i.e., pump, heater, chiller) into the bottom ofthe Control module.

Be sure you do not exceed the power specifi-cations of the Control module. The Controlmodules operate on power lines up to 110

volts and can be used with devices up to 15amps. Control modules which operate withhigher voltage and amperage or with differentinternational plug configurations, are avail-able from your dealer.

The Octopus identifies each Control moduleby its own code, which is called an address. Acontrol address must be set for each Controlmodule.

The address is selected using the two dials onthe face of the Control module, as shown inFigure 2.10. The alpha dial allows selectionsA-P and the numeric dial allows selection 1-16. The Control address shown in Figure 2.10is A-3.

STEP 4INSTALL THE OPTIONALX-10 POWER LINE INTERFACE

To install the X-10 Power Line Interface,simply plug it into a GFCI electrical outlet.Then use the 4-wire interconnect cableprovided with your unit to connect the X-10Power Line Interface (RJ-11 port at thebottom) to the Octopus 3000 controller. Forproper initialization of these components,remember to connect your X-10 Power LineInterface and Control modules before power-ing up your Octopus 3000 unit.

STEP 5INSTALL AND ADDRESSOPTIONAL CONTROL MODULE(S)

The Control modules can be located wherever

electrical power is available. It is essential,

however, that the Octopus 3000 controller,

the X-10 Power Line Interface, and all

Control modules be located on circuits on the

same phase in the electrical sub-panel and

have the distance of the A/C wiring between

the X-10 Power Line Interface and any

Control Module not exceed 50 feet. Other-

wise, these devices may not communicateproperly.

Figure 2.10 Addressing a Control Module


30/113



Before assigning any addresses, you shouldmake a list of all devices to be controlled andtheir proposed Control addresses. It isrecommended that you use the addressessupplied by Aquadyne. They will minimize therisk of control problems caused by interfer-ence. The default addresses are shown inTable 2.2. The Octopus 3000 comes pre-programmed with these addresses alreadyinstalled in the controller.

A sticker on each satellitemodule indicates the maximumload-rating of the device.

DO NOT OVERLOAD. Equip-ment such as compressors andpump motors can exceed theload rating of a Control module.Verify with the manufacturer ofyour peripheral device that thesurge current at startup doesnot exceed the load rating of thesatellite module. Damage to thesatellite unit could result!

In addition, be sure you areusing the correct plug configu-ration.

CAUTION

The X-10 Power Line Interfaceand all Control modules must beinstalled on circuits of the SAMEPHASE. If the X-10 Power LineInterface and the Controlmodules are not on the samephase, they will not be able tocommunicate with each other,except by means of a X-10Signal bridge.

Do not plug Control Modules or

the X-10 Power Line Interfaceinto power strips equipped withsurge suppression. Surgesuppression will filter out theOctopus X-10 control commandsignals.

STEP 6INSTALL THECOMMUNICATIONS EQUIPMENT

There are two optional communicationfeatures available for the Octopus 3000system:

Alarm Paging

AquaWeb for Windows 95

The alarm paging feature allows your pagerto receive an alarm page when a water qualityparameter goes outside the acceptable rangeor when a digital input switch signals analarm condition. The pager message indicateswhich Octopus 3000 unit (via the last 3 digitsof the unit serial number) is affected (in theevent of multiple units), which parameter isinvolved, and whether the alarm represents ahigh or low condition. (Refer to Chapter 3,Step 23 for a discussion of pager messageinformation.)

As shown in Table 2.3, in order to have thealarm paging feature, you must install amodem to your system.

AquaWeb for Wind ows 9 5 provides remoteaccess to the Octopus 3000 internal data-logand permits network communication betweena PC and the Octopus. Depending on thesoftware version of AquaWeb, some of thefeatures include remote communications,trend analysis and networking with extensivegraphing, statistical and data export capabili-ties.

As indicated in Table 2.3, there are two waysto access AquaWeb:

Via modem Via direct cable connection

For a single PC to a single Octopus, a directcable connection can be used (refer to Figure2.11). Note that if a direct cable connection isused, alarm paging will not be available.(Both the direct cable connection and themodem connection require a serial portconnection. And PCs typically have only oneserial port available.)

For remote access to the Octopus 3000 data-log or for networking two or more Octopus

units, a modem connection is required.

Installing the Modem

Using the AquaWeb software requires aAquadyne modem. Non Aquadyne modems arenot supported by Aquadyne. The Aquadynemodem and 10-foot modem cable (RS-232)are preconfigured to work with the Octopus3000 unit and there are no adapters needed.If you did not purchase this hardware fromAquadyne you will need to follow additionalinstructions to connect your modem with theOctopus 3000 unit. (A Tech- Tip is availablefrom Aquadyne.)

1. Connec t the Modem and the OctopusUnitFirst, plug your modem cable intothe modem/serial port of the Octopus3000 unit. Then connect the other endof the modem cable into the 25-pinconnector on the back of the modem, asillustrated in Figure 2.12.

The connectors are keyed and can onlybe installed one way. Make sure that theplugs on the cable are fully inserted intothe jacks on the Octopus controller and

the modem.

Figure 2.11 AquaNet using Direct Cable or Modem Connection

Direct Cable Connection for Local Use Only

33/113



The Aquadyne modems default settingson the dip-switch (at the back of themodem) are DUDUUUDD for switchpositions 1-8 respectively. Verify that thedip-switch settings are in the correctpositions.

2. Power up the ModemAquadynemodems are powered by a small wall-mount transformer, as shown in Figure2.12. Plug the end of the cable from thepower transformer into the front of themodem. Then plug the modem walltransformer into a wall receptacle or,

preferably, into a surge suppressorpowerstrip.

If you have an Aquadyne modem, theserial port configurations are already setto work properly with your Octopus3000 unit. If you do not have anAquadyne modem, you will need toconfigure the serial port settings on themodem. Normally, this will require thatyour settings support the port settings ofyour Octopus 3000 (baud rate of 19,200and data format of 81N). If you are usingAquaWeb, you will also need to

configure the modem to auto-answer.

A small power switch is located on theback of the modem. Set the power switchon the modem to the ON position. Whenthe modem has power, several red lightsshould be illuminated on the front of thedevice.

3. Connec t the Modem and PhoneThemodem is supplied with a 6-foottelephone cable to connect the modem tothe telephone company (telco) phoneline. Plug the phone cable into the backof the modem in the jack labeled LINE.(DO NOT plug the cable into the jacklabeled PHONE.) Connect the other endof the phone line to the closest telco livetelephone jack.

If your installation does not use thistype of phone connection, adapters areavailable through your local computerhardware store. With the cableconnected to the phone line, you arenow ready to program the H

2O/S

software for modem use. (Refer toChapter 3, Step 23.)

To hook up directly to the PC, one end of thedirect cable connects to the serial port on theOctopus 3000 unit and the other end con-nects to your PC com port. Aquadyne providesa optional 25 and 50-foot extension cablesfor longer runs.

Installing the Direct Cable Connection

Your Octopus 3000 Controller with its H2O/S

system software can be configured to connectdirectly to a PC by using Aquadynes directcable connection. Once connected, theOctopus 3000 can communicate withAquaWeb for Windows 95, Aquadynes remoteaccess application, and the H

2O/S Flash

downloader application.

CAUTION

There could be problems inmodem operation and pagerfunctionality if the telephoneline is shared. For properoperation, the modem willrequired a dedicated tele-phone line.

Use of any cable other thanthat supplied by Aquadynemay result in an incompleteconnection or, in extremecases, damage to the Octo-pus or computer.

The cable utilized for DirectCable connection is a non-standard cable. It can beordered from your dealer orfrom Aquadyne.

Along with the cabling issue the Octopus3000 allows you to control a number ofdifferent serial data options such as baudrate, parity, and software flow control.

STEP 7POWER UP THEOCTOPUS 3000 CONTROLLER

If your system includes a modem, X-10 PowerLine Interface or Control modules, be surethat these components are plugged in BE-FORE powering up the Octopus 3000.

Plug the end of the cable from the powertransformer into the power jack located onthe bottom left of the Octopus 3000 (See

Figure 2.13). Be sure to use the protectivepower cord drip loop to prevent water fromrunning down the cord into the Octopus 3000controller. The cord should extend below theoutlet so that any runoff will not enter theelectrical outlet.

When the controller is first plugged in, it goesthrough a diagnostic self check. The LCDscreen will show a series of messages indicat-ing that a self diagnosis is in progress, asshown in Figure 2.14.

When powering up the Octopus for the firsttime, make note of your system serial numberand H2O/S software version. This informa-tion is required should you find it necessaryto obtain technical support. When thecurrent status screen begins to display youwill notice that the top line of the display willshow the current probe readings. The secondline will show system activity such as sys-tems being activated, and alarms occurring.When the Current Status Screen is shown,Figure 2.15, you are ready for programmingthe Octopus controller.

dyne specifically for advanced water qualitymonitoring applications. The H

2O/S software

setup consists of Steps 9-23 in the installationprocess. A summary of these steps is given inTable 3.1. Step 15 (Entering Setpoint Values)is perhaps one of the most important of thesesteps.

STEP 9SET THE SYSTEM CLOCK(SETUP MENU)

The Octopus 3000 is equipped with aninternal clock that includes its own batterysource. So, you wont need to set the clock as

were May 16, 1997, then you would enter "05/16/97." The controller will then prompt you toverify the date before continuing to enter thetime. If you answer NO to the question"Correct?," then you have an opportunity tore-enter the date.

Next, enter the time in a 12-hour format.After the time is entered you are again giventhe opportunity to verify that what you

entered is correct. If you answer NO, then youwill be given another opportunity to enter thetime.

a result of power failure. However, becauseeach clock is set from the factory with PacificStandard Time, you may need to adjust theclock to your time zone. Control of the clock isaccessed under the Setup Menu under Timer.

Your first option in setup is to load thecurrent date. Data is loaded in the followingorder: First, the month (01=January, 02=Feb-ruary. . ., 12=December), then the day of the

month, and finally the last two digits of theyear. To enter the year 1997, you would onlyenter "97." For example, if the current date

STEP 10ENTER THEPROTECTIVE PASSWORD

The use of a password will protect yourcontroller from unauthorized use. Anyoneattempting to use the controller will not beable to enter the Main Menu without enteringthe correct password. Your password mayconsist of up to five characters, letters and/ornumbers. You may choose not to utilize thepassword protection; if so, do not enter anypassword and move to the next setup proce-dure.

Many people find password numbers easier toremember; you may want to choose a numberyou already use somewhere else, such as anaddress. To enter your password, go to theNew Password selection in the Setup Menu.

When you press Enter, you will be promptedto enter your password of up to five charac-ters. To do so, push the arrow until the firstcharacter you desire appears, then pushenter. Follow this process for the remainingcharacters of your password. If your pass-word has less than five characters, push enter

a second time to signal that your password is

complete. You will be prompted to enter thesame password a second time to ensure thatthe password has been entered correctly.When your password has been entered andverified the LCD Screen returns to the "ExitPassword" Screen.

In order to activate your password selection goto the Operations Menu, press Enter, thenscroll using the arrows to the "Lock-Unlock"menu. Push Enter and the display will show"Lock Now." Push Enter and you have acti-vated the password.

STEP 11SET THE NOISE FILTERCONTROL

The Octopus 3000 comes with a softwarenoise filter which minimizes the effects ofelectrical noise on probe measurements. Thefilter may be set to one of four states: Off, Low,Medium, or High. Unless your Octopus 3000is having problems recording data into thedata-log, we recommend an initial setting ofOff. If your aquatic environment is stable, butyour HP hand-held printer output is showingunusual high-low readings, then some

adjustment to the filter setting is warranted. Itis always advisable to first identify andeliminate the source of the interference before attempting to use the filter to achievethe same goal. The filter menu is accessedunder the Setup Menu.

Note that the noise filter does not alleviate theX-10 control problems associated with electri-cal noise. Contact your nearest X-10 controlmodule dealer who can help troubleshootinstallation problems.

Entering AQDYN at the newpassword prompt willdisplay the system serialnumber and the version ofH

2O/S software installed in

the Octopus. This informa-tion will be required shouldyou need to contact technicalsupport for any reason.

Note


43/113



STEP 12SELECT THECONDUCTIVITY TEMPERATURECOMPENSATION SETTINGS

Temperature will affect conductivity readings.Therefore a temperature compensationadjustment is provided. This adjustmentallows you to artificially adjust the conduc-tance reading in percent per degree Celsiusfrom 0 to 5% per C. As a general rule, anadjustment of 2-3% is common for the waterenvironment.

To reach the temperature compensationmenu (Temp Comp Menu), press Enter onthe Setup Menu, then press the arrow keysuntil you scroll to the Conductivity menu(Cond. Menu). When you press Enter again,you will be at the Temp Comp Adjust Menu.

NOTE: You can test the required percentadjustment setting by using water tempera-tures of known conductivity value andobserving the conductivity readings. Thereadings should stay constant as the waterchanges temperature.

STEP 13SELECT ACONDUCTIVITY RANGE

The conductivity range menu allows you toset the appropriate conductivity scale. This isimportant since the conductivity range ofwater varies greatly depending on the applica-tion. Saltwater, for example, ranges fromabout 45,000 to 55,000 S (45mS - 55mS),whereas freshwater conductivity is typicallybetween 800 and 1,500 S, depending on thewater source. Hydroponic and other applica-tions can vary across a broad range as well,depending on the crop and the stage of

growth.

You will need to select the conductivity scalethat is appropriate for your system. Theconductivity scale choices are 0-1000 S (lowrange), or 0-100 mS (high range). The firstscale is a much more sensitive scale since itreflects changes in conductivity of only onemicroSiemen (1 S). The second scale is lesssensitive and reflects conductivity changes inincrements of 100 S.

From the Setup Menu, press Enter to reachthe submenus. Use the directional keys to

STEP 14SELECT ATEMPERATURE SCALE

The temperature scale menu allows you toselect the scale you wish to use for tempera-ture measurementCelsius or Fahrenheit.The Octopus 3000 controller is set to Fahren-heit at the factory.

Changing the temperature scale automaticallyrecomputes your setpoints. For example, ifyour setpoints were entered in Fahrenheit andyou change the temperature scale to Celsius,

all of your setpoints will be automaticallyconverted to their Celsius equivalents.

The Temperature Scale Menu is accessed bypressing Enter at the Setup Menu. Use thedirectional keys to scroll through the menuoptions until the temp scale menu is reached.Press Enter to access the item, and use thedirectional keys to choose a temp scale.

STEP 15ENTER SETPOINT ANDRANGE VALUES

Various setpoints and ranges must be estab-

lished for each of the four monitoring param-eters: conductivity, temperature, pH and ORP

There are three values that must be entered:

The optimal setpoint value (in Step 15).

The control range (in Step 15.

The alarm range (in Step 16).

When these three values are entered, thesystem will operate as illustrated in Figure3.5. As long as the water quality parametersremain within the acceptable operating range,no control or alarm will be activated. If,however, the parameter rises above or falls

below the acceptable operating range, theOctopus 3000 will activate the appropriatecontrol device. The control device remains inoperation until the parameter returns to theSetpoint value. (For ORP, the control deviceremains in operation until the ORP valuereturns to the HIGH control point.)

Entering Data on the Setpoints Menu

Generally speaking, you enter or change anysetpoint by first pressing Enter from anyposition on the Top Level Display. This will

bring you to the Setpoints Menu. Press Enterand you will be at the Temp Setpoint menu.Scroll left or right using the arrows until youarrive at the desired parameter. Press Enter.When the current setpoint is displayed, pushthe right arrow to increase the value or theleft arrow to decrease the value. Once thesetpoint value you want is displayed, pushEnter once to register your selection. Table 33shows which parameters need to be set formonitoring and alarming functions and theadditional settings needed for adding control.

As you choose a setpoint value, check the

System Status light. The light should be solidgreen. If the light turns yellow as you areselecting your value, the setpoint is out of thenormal value range for that parameter. Adjustthe setpoint accordingly.

Conductivity Setpoints

To enter the conductivity optimal setpointvalue, press Enter from any place on the TopLevel Display. You will be at the SetpointsMenu. Press Enter and you will be at theTemperature Setpoints Menu.

Using the left arrow key, scroll to the conduc-tivity menu and press Enter. At the flashing

need to enter other values in the SetpointsMenu including dosing times for low and highconductivity, and dwell times.

A dwell time is the length of time that theOctopus 3000 will wait until dosing can occuragain. This feature prevents overdosing asystem with a dosing solution and protectsagainst short cycling of equipment.

Conductivity Example

Suppose that you desire an optimal setpoint

value of 45 mS, an operating range of 5 mSand an alarm range of 3mS. Figure 3.5illustrates the relationship between theoptimal setpoint value, and the control range.

For these systems, if the conductivity valueremains within the target operating range, theparameter status light will not be illuminated.If the conductivity value enters the controlrange, the parameter status light will turneither red if the low conductivity dosingsystem is enabled, or green if the high con-ductivity dosing system is active. If theparameter status light is flashing red, the low

conductivity dosing system is in a dwell state.A high conductivity dosing system dwell stateis indicated by a flashing green parameterstatus light (See Figure 1.2).

Temperature Setpoints

The temperature setpoint defines the opti-mum water temperature. In a control applica-tion you will also need to enter the controlrange on the Setpoint Menu.

To enter the temperature setpoint, go to theSetpoints Menu. Press Enter and you will beat the Temperature Setpoint Menu.

When you press Enter again the currenttemperature setpoint will begin flashing onthe LCD display window. Pushing the rightarrow will increase the setpoint value andpushing the left arrow will decrease thesetpoint value. When the desired value is

displayed, push the Enter key to select it.

If the system is configured for monitoring andcontrol, you will need to enter values for thetemperature range in addition to the tem-perature setpoint. This determines thecontrol range for heating and chilling devices.

Since most heaters and chillers have theirown thermostat, these thermostats can beused as a backup temperature control system.The heater thermostat should be set severaldegrees above your desired temperature andthe chiller several degrees below. If your

desired temperature is 78F then set yourheater thermostat at 81F and your chillerthermostat at 75F.

Temperature Example

Suppose you have a setpoint value is 78.2 F,your target operating range is 0.1 F, and thealarm range is 0.1 F. (Figure 3.5 illustratesthe relationship between the setpoint value,and the control and alarm ranges.)

If the temperature stays within the targetoperating range (78.178.3 F), the parameterstatus light will remain off.

If, however, the temperature enters the controlrange (between 78.1F on the low side and78.3F on the high side), the parameter statuslight will either turn green if the chillingsystem is active, or red if the heating systemis active.

At the beginning of the control range, theOctopus will turn on the chiller or heater, asneeded. These peripheral devices will remainactivated to drive the temperature value back

to the optimal setpoint, and once achieved,the peripheral device will be turned off.

Configuration data such assetpoint values, are stored inpermanent (nonvolatile)memory. Should primary orbackup power to the Octopusbe lost, the setpoint values willbe restored to their previousvalues when power is restoredto the Octopus.

Note

Note that the chiller system hasa protective feature that pre-vents the chiller from turningon/off more often than every 10minutes.

pH Setpoints

The pH setpoint defines the optimum pH levelthat you wish the Octopus 3000 controller tomaintain in the aquatic environment. Toenter a pH optimal setpoint value, go to theSetpoint Menu. Press Enter and use the rightarrow to reach the pH Setpoints Menu. Whenyou press Enter, the current pH setpoint willflash on the LCD display. Push the rightarrow to increase the setpoint value or the leftarrow to decrease the setpoint value. Whenthe desired value is displayed, push Enter toregister your selection. Other setpoint valuesare entered similarly. For controlling pHadditional values must be entered on the Set-points Menu, including the dose and dwell values.

The Octopus can control the pH system by dosinga buffer solution or injecting CO

2gas or do both.

The pH control range is selectable from 0.05pH units to 1.00 pH units, and determinesthe ON points for the pH and CO

2dosing

systems.

The Current Dose in minutes (time per dose of

buffer solution) will flash on the screen. Thisis the number of minutes that the Octopuscontroller will dose buffer to bring the pHlevel back up into the Setpoint . The accept-able values for buffer solution dosing are from1 to 99 minutes.

Dose times will range from 0-99 minutes. Youare also required to enter a dwell time TheDwell Time is the length of time that theOctopus 3000 will wait until dosing can occuragain. This feature prevents overdosing asystem with buffer.

The next option is the setting of the CO2Dosing, in seconds. This controls how longthe CO2gas valve will remain open. Thepossible values range from 0 to 99 seconds.For example, if you enter 10 seconds, whenthe upper end of the target operating range for

pH is reached, the Octopus will turn on theCO2gas for 10 seconds to reduce the pH to alower value. A CO

2Dwell Time will force the

Octopus 3000 to wait to allow the gas to beabsorbed into the water. This will prevent thepH value from dropping to fast.

If you enter a value of 0 seconds, then theOctopus 3000 will turn the gas valve on whenthe pH level reaches the high end of the targetoperating range and will keep the valve openuntil the pH drops below the optimal pH level.The 0 seconds option is for systems withpressurized CO2injection.

The last pH control selection is the CO2dwell

time. This is the time that the Octopus waitsbefore allowing another CO2gas injection tooccur. This time is selectable from 1-255minutes.

If the Octopus 3000 senses that the pH isoutside of the target operating range, it will

ORP Setpoints

The ORP setpoint defines the acceptable levelof oxidation reduction potential in theaquatic environment. The ORP level is anindicator of ozone. Acceptable levels arebetween 200 and 450 mV. The ORP setpointcan be maintained through the use of anozonizer in Monitoring and Control System.However, unlike the proceeding parameters,the ORP setpoint has a FIXED range of 5mV.

Verify All Setpoint Settings

You can easily view the parameter setpoints.From the Top Level Display, simply pusheither the right or left arrow keys to scrollthrough the screens. Each successive push ofan arrow will display another setpoint untilit returns to the current status screen. PushEnter at any time to enter the other menus.

STEP 16ENTERING ALARMRANGE

General Alarm System

The alarm is located in the Setup Menu underAlarms. All alarm ranges are entered in thismenu. The alarm range can only be entered ifthe alarm system itself is also enabled first. Inaddition to an alarm range for each systemthere is a common alarm hold-off time whichcan be entered. This will prevent any systemfor generating an alarm until the hold off time

has expired. Table 3.5 lists all system param-eters that are located in the Setup menurelating to alarming or system configuration.

When a alarm occurs the status line on theLCD screen will show which system(s) had thealarm and whether the alarm was a high orlow alarm condition. When the hold-off timehas expired the controller will generate anaudible alarm and initiate a alarm page if thepager system is enabled on the controller. Thealarm condition is reset by pressing the Enterbutton on the front of the controller. Pressingthe Enter key during an alarm will stop the

audible alarm and cancel any pending pagesbut the alarm status messages will NOT becleared until the alarm condition is no longersensed by the controller.

Alarm will be triggered when the value mea-sured falls outside of the control range. (See

Figure 3.5).

The high or low alarm triggerpoints are computed by addingthe control value and the alarm

value to the setpoint value.

Conductivity Alarm

The conductivity alarm range is entered in theSetup Menu under the Alarms sub-menu.From the Setup Menu, press the Enter key.Then press the right or left arrow until youreach the alarm menu. Press the Enter keyand you will go to the pH menu. Scroll leftusing the arrows until you get to CondAlarm. Press enter and then select Enabledand press Enter again. You will automaticallybe directed to the conductivity alarm rangemenu.

As long as the conductivity value of the waterstays outside the alarm range, (i.e. within theacceptable operating range or control range),the alarm will not be triggered.

If the conductivity value goes outside thecontrol range, an alarm will be triggered. Thealarm condition will be confirmed by an alarmstatus message appearing in the LCD screen,the sounding of an audible alarm, and theissuance of a pager alarm (if installed), oncethe hold-off period has expired. (See Figure3.5)

In addition to the general conductivity alarmthere is also two separate conductivity alarmoutputs which can be configured in the SetCtrl Address menu. One for a low conductivityalarm and the other for a high conductivityalarm. Theses outputs will go active in a lowor high conductivity alarm condition.

Temperature Alarm

The temperature alarm range can be set from0.10 degrees to 2.00 degrees. The tempera-ture alarm range can only be set if the tem-

perature alarm is enabled.

An alarm will be triggered when the valuemeasured falls outside of the control range.

For example, suppose you have a optimaltemperature setpoint value of 78.0 F and anacceptable operating range of 0.1. Figure 3.6illustrates the relationship between thesetpoint value and the acceptable operatingrange. When the parameter value stays withinthe acceptable operating range (77.978.1 F),the system monitoring function will notdetect an alarm and the parameter statuslight will be off.

If, however, the temperature drifts past theacceptable operating range (below 77.9 F or

above 78.1 F), an audible alarm will betriggered, the monitored parameter will begin

flashing on the current status screen, and apager alarm will be issued (if installed), uponthe expiration of the hold-off period.

As a second example , suppose you have asystem with the same values as above butwith a temperature range of 0.2F. If thetemperature value drifts away from the targetoperating range and comes to the controlrange (lower than 77.8F or higher than78.2F), then the peripheral device (heater orchiller for example), will be activated. If thetemperature continues to drift away from the

target operating range and comes to the end ofthe control range (i.e. 78.3F),then the heater or chiller will remain activebut an audible alarm will be triggered, themonitored parameter will begin flashing onthe LCD display window, and a pager alarmwill be issued (if installed), upon expiration ofthe hold-off period.
