ComTroller 702

1 General

MJK Comtroller 702 is developed for control andsurveillance of small pumping stations and waterborings. Comtroller 702 is a complete unit with in-and outputs, CPU, data logger, real time clock andcommunications port for data transmission onowned lines.

Comtroller 702 is an advanced product based onthe experience from the thousands of monitoringsystems delivered during the past 15 years.

Comtroler 702 is an advanced product for on-sitemounting with control, data logging storing andtransmission of analog and digital measuring valuesto be used in both small and large SCADA sy-stems.

Comtroller 702 is typically arranged in clusterswhere each Comtroller is connected to a 2-wirecommunications line. A Data Transmitter 795 isthen connected as a master communications unit.Every single Comtroller 702 can be calledindividually by their different ID numbers, and theData Transmitter 795 simply handles the datatransmission via a telephone modem, a radiotransceiver or a GSM modem directly to theSCADA system.

Comtroller 702 has all necessary functions built insuch as interface to measuring and controlequipment, a data logger, counters and data

transmission. Comtroller 702 is programmed directlyfrom a PC, from the SCADA system or via a MJKData Transmitter 795 as a master communicationsunit.

Comtroller 702 is a compact unit containing allnecessary functions such as communications inter-face and drivers, software, I/O ports, data storagememory and RS485 repeater.

Comtroller 702 is simple and economic to utilizesince it contains all necessary facilities to decreasethe number of external components needed toform a complete unit for control, monitoring anddata transmission.

The RS 232 port is used for interconnectionthrough external modems, GSM-modems or a PCfor configuring or data readout.

1.2 MJK-Link™The MS-Windows™-based program MJK-Link™can be used for monitoring one or more Comtroller702. It is possible with MJK-Link™ via a PC with amodem to read realtime values, stored values forinvestigation of storm flows and changing ofsetpoints.

This manual deals with MJK Comtroller 702 withComli-protocol for telephone modems. GSM-modems, RS 485 on owned lines, powerlinemodems and closed radio networks.

Screen dump from the monitoring program MJK-Link™, where a pumping station with 2 pumps, monitored andcontrolled by a Comtroller 702 are operated in a window that appears as the well-known MJK Data Transmitter 795.

ComTroller 702

The figure shows an overview of the functional buttons and their general function.

2 OperationA Comtroller 702 can be considered as a DataTransmitter 795 without display and keypad andwith a built-in pump controller. Instead of displayand keypad the Comtroller 702 is operated via theserial communications port from either a PC withMJK-Link™ or a Data Transmitter 795.

MJK-Link™ is used for monitoring and operation ofComtroller 702. The Comtroller 702 will appearexactly as a Data Transmitter 795 in MJK-Link™with its well-known 2 x 24 character display andkeypad. The kepad is simply operated via the PCkeyboard.

MJK-Link™ makes it possible to upload,download and save the settings for one or moreComtroller 702's interconnected on the same multi-drop communications æline. It is thus possible todownload the setting from Comtroller no. 9, savethe setting as i.e. "Pumping station at the bend"and upload the setting to Comtroller no. 14, placedat "Pumping station at the pond". It is also possibleto name the in- and outputs individually.

A Data Transmitter 795 with Master-software canalso be used to operate a number of Comtroller

702's on the same multidrop communications line.The desired Comtroller 702 is selected by enteringthe corresponding ID-number on the Data Trans-mitter 795, after which the selected Comtroller canbe operated exactly as if it were a Data Transmitter795. At the same time the Data Transmitter 795contains a surveillance function that calls theComtrollers one by one over an adjustable interval.If a Comtroller does not respond, the Data trans-mitter will send a system alarm.

A Data Transmitter 795 also managescomunication to the SCADA system, MJK-Link™etc.

A typical installation covers five to 20 Comtrollers inan area where communication takes place viaowned lines or with MJK PowerLine modemsthrough the mains supply network.

On ie. the main pumping station, a Data Transmit-ter 795 with master software is installed, which willbe able to send alarms via a telephone- or GSMmodem to the SCADA system and/or one or moremobile telephones as SMS messages.

3 Menus

3.1 F0 - Unit type/ID, software version, clockand protocol type

Menu F0 show the MJK unit type, protocol type,program version and date / time.

MJK 702 : 3 COMLI 83080216:07:29 24/10/01

In above example, the Data Transmitter isconnected to a Comtroller 702 with unit ID no. 3.

The Unit ID no. is set binary by means of 8switches on the front panel. (All OFF = 0 - All ON =255.) Note! The unit ID no. must be set within therange 1 to 247.

3.2 F1 - Inputs on/offIn menu F1 is shown whether the digital inputs areON or OFF.

INPUTS 1 2 3 4ON : OFF:

In above example, DI no. 1 and 2 are ON while DI3 and 4 are OFF.

A delay time can be set individually for each digitalinput in order to allow the input to go ON withoutactivating i.e. an alarm. (See section 6.)

When the input is OFF an empty field is shown.When the input is ON, the field will flash for theduration of the delay time. When the delay timehas expired, a full field will be lit.

3.3 F2 - Outputs on/offMenu F2 show the status of the digital outputs.

OUTPUTS 1 2 3 4ON : OFF:

In above example, DO no. 1 and 2 are ON whileDO 3 and 4 are OFF.

A delay time can be set individually for each digitaloutput in order to delay the activation of thecorresponding output relay. (See section 7.)

When the output is OFF an empty field isshown. When the output is ON the field will flashfor the duration of the delay time. When the delaytime has expired, the output relay is activated andthe field will be shown in a steady state .

3.4 F3 - Limits high/lowMenu F3 indicate if the high and low limits for theanalog inputs are exceeded.

The first two fields indicate if the high limits areexceeded and the last two show if the low limitsare exceeded.

LIMITS HIGH/LOW 1 2 3 4 5 6 1 2ON : OFF:

A delay time can be set individually for each analoginput allowing the input to exceed the limitmomentarily without i.e. activating an alarm. (Seesection 5.)

If the analog input are within limits, the field will beempty. If the limits are exceeded, the field will flashduring the delay time. When the delay time hasexpired, the field is shown in a steady state.

3.5 F4 - Analog inputs #Menu F4 shows the immediate value of an analog in-put as a horizontal bar formed of up to 24 fields. If theinput signal is 4 (0) mA (see also section 5.2), none ofthe fields is lit (0 %). If the input signal is 20 mA, all 24fields is lit (100 %).

ANALOG INPUT NO #

Select the desired analog input with the arrowkeys or by keying the corresponding input number(1 - 2).

3.6 F5 - Analog input scaledMenu F5 shows the immediate value of an analoginput in digits rather than a horizontal bar as in theprevious menu.

The first set of digits read out the signal value asthe percentage between the low mA value (0/4mA) (see also section 5.2) and the high mA value(20 mA). The next set of digits read out the samesignal multiplied with a programmable scaling factor.

The readout scaling is determined by programmingthe desired readout range corresponding to thelow mA value (0 / 4 mA) and the high mA value (20mA) respectively. If e.g. a tank level is measured,and the level varies between 2 metres and 3metres, the low mA value is set to correspond to"200" and the high mA value is set to "300". A levelmeasurement of i.e. 2,5 metres will corespond to asignal value of 50 %, resulting in a readout of "250"(See section 5.3 - 5.4)

ANALOG INPUT NO #50 % SKALERET 250

Select the desired analog input with the arrowkeys or by keying the corresponding input number(1 - 2).

7.3 Time / FixedA time controlled output is only ON for a certainperiod of time (the ON-time) whereafter it goesOFF. A fixed output which is turned ON mustreceive a command in order to set the output OFF.


7.4 Time before startEnter the delay time before start - which is the timepassing from an ON-command is transmitted untilthe output responds.



7.5 Set ON-timeEnter the ON-time for the output. The On-time isthe period of time the output is turned ON if theoutput is set to "time controlled".



7.6 Special functions for the digital outputs(This menu is only accessible if 'Fixed' is selectedas described in section 7.3.)

It is possible to perform AND logic sequences bymeans of the digital in- and outputs.

For example the Comtroller 702 can be program-med to activate a digital output when 2 digitalinputs are ON. The digital signals can also derivefrom exeeding a limit value on an analog input - ora combination of a signal caused by exceeding alimit value and an active digital input.

The following signals can be combined:

- digital input 1 - 4- analog limit HIGH 1 - 2- analog limit LOW 1 - 2- combi alarm 1 - 8

8 InterlockWhen interlocking two MJK Comtroller 702's theywill communicate with one another. In this way onedata transmitter can control a digital outputremotely on the other.

8.1 Interlock in use yes/noSelect whether the interlock function is to be usedor not.


8.2 Start of interlockSelect the signal which - when it goes ON - willmake the Comtroller call the other Comtroller andset an output ON.


The following signals can be selected:


As long as the signal is ON, calls will take place in10 minutes interval. The remote controlled outputmust therefore be set to "time controlled" andconfigured with an ON-time of more than 10minutes (e.g. 15 min.), thus securing that the out-put is not constantly ON if an error situation shouldoccur (e.g. a broken telephone cable). This waythe output is certain to go OFF even in the case ofcommunication failure.

At faultless communication the ON time of theremote controlled output will be initialised at eachcall and the remote controlled output will stay ONas long as the controlling signal is active.

8.3 Stop interlockSelect the signal which - when it goes ON - willmake the Comtroller call the other Comtroller andset an output ON.


The following signals can be selected:


Only one call attempt will be made. If the samesignal is chosen both as start and finish conditionfor the inter lock, the finish condition will be whenthe signal goes OFF.

10 Telephone list for alarms(This section applies is only

10.1 Telephone number 1-9In this menu up to 9 telephone numbers are keyedin which will be dialed chronologically at an alarmsituation.

Press key 1 - 9 to select the number which is to bechanged, press ENTER to change the receivertype (PC, Pager, ph [phone], SMS), press ENTERto correct the number - key in the number with thenumerical keys, and confirm with ENTER.

After keying in the telephone number the MENUkey must be used in order to move on to the nextmenu, the ENTER key will be of no use here.

When calling through a switchboard, a * can beused for awaiting a dialtone. A * gives a pause of 2seconds. I.e. 0*00454556,656##23 means:

First dial 0 to get an external line, await the diallingtone, then dial 0045 45560656, wait for 4 seconds,then dial 23.

In the parenthesis following the number, it is statedwhich type of reciever the call has been made to.When calling a modem set to 1 [PC]. When callinga beeper / pager set to 2 [Pager]. When calling anordinary telephone set to 3 [PHONE].

10.2 Key In PS MessageIf a telephone number has been chosen as a PSnumber, a message of up to 8 digits can be typedin (e.g. the telephone number of the data transmit-ter), the message can be different for the varioustelephone numbers. The message for the pager isshown in the pager display together with a codefor the alarm, which has caused the call.

The alarm codes are:

01 : Digital input no 102 : Digital input no 203 : Digital input no 304 : Digital input no 4

21 : Analog limit no 1 LOW22 : Analog limit no 2 LOW

31 : Analog limit no 1 HIGH32 : Analog limit no 2 HIGH

51 : Combi alarm no. 152 : Combi alarm no. 253 : Combi alarm no. 354 : Combi alarm no. 455 : Combi alarm no. 556 : Combi alarm no. 657 : Combi alarm no. 758 : Combi alarm no. 8

90 : Comtroller power failure

E.g. a datatransmitter with telephone number455660656 where digital input 5 has an activealarm input; will give the following alarm messagein the PS:

05-45560656

The configuration is stored in a EEPROM which isnot lost even if the supply is disconnected

10.3 Entering SMS messagesUp to 8 characters can be entered here if a recei-ver type is selected as an SMS type.

It is possible to enter digits as an SMS messagevia Data Transmitter 795, and with MJK-Link32™ itis also possible to enter a text.

The SMS message will be shown on the cellularphone with "MJK-702" as the opening text,followed by the cause of the alarm and thecorresponding SMS message. If a GSM modemare used as communications unit, the pagermessage will be changed to an SMS message.Check the SIM card in a cellular phone if no SMSmessage is transmitted, and check, if the phonenumber to the SMSC-server is correct. The phonenumber to the SMSC-server depends on the GSMnetwork service provider.

When sending SMS messages and pagermessages, it is not possible to check whether themessage is sent to the recipient or not, since themessages are delivered to an external server.

11 Programming of storm flowcalculation

11.1 Stormflow calculationComtroller 702 can be applied for calculation ofstorm flow by means of one digital and analogueinput. Generally Comtroller 702 is applied to a levelmeter with measuring range adapted to the pumpcontroller. This measuring range is normallyconsiderably higher, than what is necessary forflow measurement, generally 10m for the pumpcontroller and 10-20cm for flow calculation. Theaccuracy of the pump controller’s levelmeasurement is as the whole measuring range.The data transmitter will compensate by means ofa digital input. An electrode relay, e.g. MJK 501and a level electrode e.g. MJK 222860 areapplied.

The level electrode is applied where the storm flowstarts. By this, the chosen level meter will be inzero position and calculate flow on the level signal.This will improve the accuracy 10 to 15 times inshort term. The system provides a simple andaccurate measurement to a reasonable price.

11.2 Stormflow calculation in use Yes/noIndicate application of stormflow calculation.

Use the arrow keys and confirm with enter key.

11.3 Zero-point DI #Indicates the digital input that sets zero-point andactivates the flow calculation.

Choose between AI 1-2

Use the arrow keys, confirm with ENTER.

11.5 Key in the number of Q(h) points (1-9)Indicate the number of Q/H points for singlelinearization of the actual flow. The number can beset between 1 and 9, as zero-point is set to a flowof 0 m3/h.

Use the arrow keys and confirm with ENTER.

11.6 Key in the level markKey in the level (h) in a Q(h) – point. Use the keys0-9, confirm with ENTER.

The level must be higher than the previous.

11.7 Key in the flow markKey in the volume (Q) in a Q(h) point. Use the keys0-9 and confirm with ENTER.

12 Combi alarms

It is possible by means of a combi alarm to set off analarm call when 2 digital signals is activatedsimultaneously. A digital signal can derive from adigital input or from a limit alarm.

12.1 Combi alarm #Use the arrow keys or enter 1 to 8 to select thecombi alarm to be programmed.

12.2 Combi alarm in useSelect if the combi alarm should be used. Use thearrow keys and confirm with ENTER.

12.3 Combi alarm signalsSelect the two digital signals to be AND'ed toactivate a combi alarm. The following digital signalcan be selected:

- digital input 1 - 4- analog limit HIGH 1 - 2- analog limit LOW 1 - 2- power failure

12.4 Signal delaySelect the delay for the combilalarm. The delaytime is the time the two digital signals should beactive at the same time to set a combi alarm.



12.5 Combi alarm callsSelect if a combi alarm should set off an alarm call.Use the arrow keys and confirm with ENTER.

13 Alarms

13.1 Operational or alarm signalThe digital signals can be chosen as eitheroperational or alarm signals.

A operational signal can be defined as non-critical,i.e. a signal, that one want to be registered.Typically a signal, that indicate if a pump is runningor not.

An alarm signal is on the other hand a signal, thatnormally is inactive and only will be active, when afault condition occurs. A thermal cutout on a pumpis a typical alarm signal.

Alarm signals has memory and reset, i.e, when thealarm signal becomes non-active, it will bememorized that the signal has been active. The"active" state must be reset by the user before anew active signal can be accepted as an alarmsignal. For both types of signals applies that boththe number of active conditions and the time framewithin the signal has been active, will beregistered.

13.2 Alarm callsIf the function "Alarm - call by telephone" isselected (see section 6.5), the Comtroller 702 willstart a call routine by making a call attempt to thefirst number in the phone list, then the next numberetc.

There will be a pause between the call attemps.See also section 10.

When dialing to a telephone modem, it will be theSCADA terminal that will be responsible forresetting the alarm and stop the call routine.

When dialing a pager or telephone, the call routinemust be stopped with a telephone call back to theComtroller. This procedure will not reset the alarm,only stop the call routine. If an alarm occurs duringthe call routine, the call routine will not stop, i.e.the new alarm will not be reported until the nextcall succeeds.

The telephone list is not used if the RS485 port areused for communication (via radio modem,Powerline modem owned lines etc.). All alarm callsis sent to the Master communications unit.

13.3 Reset of alarmsWhen a digital alarm signal becomes active, it willbe displayed in function menu F 8.1. Functionmenu F 8.2 will display the input number and typecausing the alarm, the corresponding alarm desig-nation, the immediate status of the alarm and thetime when the alarm was set.

When a digital alarm signal become active, thealarm status will be shown in funtional indicationF8.1. In functional indication F8.2 will be shown:the type of alarm, the time of start and a symbol

indicating the status. The symbol flashes until thealarm is registered which makes the symbolpermanently lit. The symbol stays lit until the alarmsignal is no longer active, then the signal disapearsand the stop time will show instead of the starttime.

To reset an alarm directly from the Data Transmit-ter keyboard, the display must show indicationF8.1. With the arrow keys the alarm to cancel ischosen then press ENTER. The symbol will thenstop flashing and the alarm is registered.

An alarm can also be reset from the SCADA sta-tion via modem. This is carried out via thecommunications protocol. If you do not wish tohave more calls on the account of a specific alarmsignal, it can be left unregistered, and there will beno more calls, even if the signal changes from notactive to active.

If the alarm is not registered, and a further 9 alarmsoccur, i.e. the unregistered alarm becomes no 10the alarm will be cancelled.

13.4 Special factory codesComtroller 702 is provided with functions whichshould not be served by the final user.

13.5 Access codeIf the access code is lost, the code 1111 can alwaysbe used.

13.6 Setting up the serial portIf the service code 2222 is used, it gives access toadjustment of the baud rate. Contact the technicalhotline for help.

13.7 Forced reset to factory settingsIt is possible to reset all settings to factory setting,meaning that all settings must be made onceagain. Use service code 2045.
