General
The TKP / TKC Controllers include all necessary functions usedin refrigeration and freezing applications:
l Temperature control , locked during defrostl 2nd setpoint for overnight energy savings,
controlled by internal clock or external signal.l Warning thermostat for every evaporatorl Evaporator fan controll Defrost control by internal clock or external signall Defrost thermostat with sensors for each evaporatorl Defrost safety limiterl Demand defrost control (by temperature-differential)l Demand defrost control (Optimizing-Method)l Runtime controllllll Roller blind controll Frame heater control
The most important feature of the TKP / TKC controller series isflexibility and easy operation without the need for any plug-onservice tools. The parameters and values are shown uncoded ona backlit LCD- display together with a lot of information and dataon the application.The user can change the configuration of this controller in the field,thus the same hardware fits all the different applications incontrolling refrigeration and freezing devices. The controllers canbe networked together with other ELREHA controllers.This enables the user to operate the controllers remotely. Thedifferent possibilities range from a PC-controlled network to anetwork with the Central Compound Control Unit VPR 3000.For places with a high interference rate the TKP 3xxx is availablewith an optional fibre optics interface.

Selectable Versions
The "TKP_3/TKC_19 Version" parameter (mode-page)allows the user to select one of several built-in versionswhich fits his application best.Each version is tailored to meeting the requirements
of a typical refrigeration/freezing device with various functions.With the version the controller changes the function of theinputs and outputs (see table on page 21).Normally this parameter is fixed during the runup, but it can bechanged by a master system (VPR 3000 or PC/Software).

Technical Manual TKP / TKC valid for Software Vers. 970225/1sha Page 2
Version: AApplication: Two (2) separate control circuits with one (1) evaporator each. This controller version is used in applications
where two individual cooling circuits are to be controlled and each single circuit has not more than one evaporator.Since there is no extra relay output for the fan, the fans run constantly or are hooked up to the cooling output.
Warning: The temperature warning thermostat uses a common offset from the individual setpoints. The warning output iscommon for both circuits.
Defrosting: Defrosting is initiated from either the built-in timer or from a remote signal. Defrosting on demand (optimizingmethod) can be selected. Sensors in the evaporators are used for individual defrost termination whilst the selected(safety) termination time is common for both circuits. Cooling comes on again upon defrost termination of both circuits.
2nd Setpoint: The internal timer or a control input can be used for toggling between two (2) setpoints. The 2nd setpoint is oftenused for overnight operation with increasedtemperature for energy savings.
Special Function: One sensor is called the 'shop sensor' andcan be used to capture any temperatures. Ver-sion A contains roller blind / frame heatercontrol. A separate control input allows ofswitching the controller in ‘standby’. This cancelsout the control functions but keeps the controllerunder power.

Version: FApplication: So this version is used in single control circuits with up to two (2) evaporators where the fans are to be
controlled and defrosting is initiated on demand according to the actual amount of icing . The main featureof this controller version is the demand defrost by the differential method. One room sensor is used as the controlsensor and the other room sensors are used for monitoring and temperature warning.
Warning: Temperature warning is activated if the value of one room sensor increases a set offset from the setpoint. All temperaturewarning works on one output relay.
Defrosting: Defrosting is requested by temperature difference and unblocked by either the built-in timer or a remote signal. Eachevaporator has its own defrost termination sensor whilst the selected (safety) termination time is common for bothevaporators. Cooling is cancelled until all evaporators have finished their individual defrost cycle.
2nd Setpoint: The internal timer or a control input can be usedfor toggling between two (2) setpoints.
Special Function: The user can select one relay output forcontrolling the roller blind or the frame heater .A separate control input allows of switchingthe controller in ‘standby’. This cancels out thecontrol functions but keeps the controller underpower.

Version: IApplication: Chest freezers, refrigerated shelfs or similar consisting of one (1) pilot element and three (3) slave elements wit h
one (1) evaporator each.The control sensors are placed at the 'air out' opening, one additional alarm sensor is placed at the 'air in' opening. Sincethere is no extra relay output for the fan, the fans run constantly or are hooked up to the cooling output.
Warning: Temperature warning is activated if the value of one of the sensors increases a set offset from the setpoint 1.All temperature warning works on one output relay.
Defrosting: Air circulation defrosting . Defrosting is initiated from either the built-in timer or from a remote signal and disables thesolenoid valves. Defrosting on demand (optimizing method) can be selected. Each evaporator has its own defrosttermination sensor whilst the selected (safety) termination time is common for all evaporators. Cooling is cancelleduntil all evaporators have finished their individual defrost cycle.
2nd Setpoint: The internal timer or a control input can be usedfor toggling between two (2) setpoints. The 2ndsetpoint is often used for overnight operationwith increased temperature for energy savings.
Special Function: A 'shop sensor' can be used to capture anytemperatures. The user can select one relayoutput for controlling the roller blind or theframe heater . A separate control input allowsof switching the controller in ‘standby’.

Version: NApplication: Walk-in coolers with a single compressor, up to three (3) evaporators and controlled fans.
For the fan(s) ‘Intervall’ or ‘Permanent’ mode can be selected and a start up time delay after defrost eliminates waterbeing splashed around.
Warning: Temperature warning is activated if the value of one of the control sensors increases a set offset from the setpoint.All temperature warning works on one output relay.
Defrosting: Air circulation defrosting . Defrosting is initiated from either the built-in timer or from a remote signal and disables thesolenoid valves. Defrosting on demand (optimizing method) can be selected. Each evaporator has its own defrosttermination sensor whilst the selected (safety) termination time is common for all evaporators. Cooling is cancelleduntil all evaporators have finished their individual defrost cycle.
2nd Setpoint: The internal timer or a control input can be usedfor toggling between two (2) setpoints. The 2ndsetpoint is often used for overnight operationwith increased temperature for energy savings.
Special Function: Version'N' is monitoring the 'security chain'(security devices), if the chain is open, allcontrol and regulation functions are stopped.
Parameter: The parameters listed below are available if'TKP_3/ TKC_19' (Modes) is set to "Version N"

page, where "Setpoint Channel x" is the first setpoint and "2ndSetp Channel x" is the secondary setpoint of the individualchannel.
Internal TogglingThe internal timer can toggle these setpoints automatically at agiven time. Parameter "2nd Setting ON" fixes the time for thesecond setpoint to become activated. Parameter "2nd SetpointOFF" fixes the time for the setpoint toggling back to normal.Don‘t forget to activate the timer by tieing the external toggle inputto phase (230 V AC). If the internal timer is not used, set ON andOFF times to ‘24:00’.
External togglingIf the external toggling input is open, the 2nd setpoint is activatedall time and the internal timer is disabled.With this input to phase (230 V AC), the normal (1st) setpoint isactivated and the internal timer is enabled. If setpoint toggling bythe timer is to be disabled, set ON and OFF times to ‘24:00’.
Run Time Monitoring
The controller adds up the running hours per day of the coolingoutput internally. This value is displayed under parameter "RunTime Cool x" for each channel. One day counts from 18:00 to18:00 of the next day.A parameter "Cooling Limit " can be set to a reasonable value(hours per day) which, when exceeded on three days in a sequence,will cause an alarm.
This alarm is to be cancelled via the network or bydisconnecting the supply voltage from the controllerfor a short time.
Temperature Warning
Any over- or undertempera-ture condition results in a tem-perature alarm which causesthe normally energized alarmrelay to de-energize. Herebythe N/O contacts open andthe N/C contacts close. Toavoid alarming for short irre-gular conditions there is analarm delay which can be setwith the "Warning Delay" pa-rameter. The alarm conditionis indicated with an LED at the front of the controller. The alarm iscancelled automatically when the temperature is back to normal.
Overtemperature WarningIf the temperature at any room sensor or control sensor getshigher than the effective setpoint plus the "Warning Offset" setting,an alarm will come on with the delay explained above.
Undertemperature WarningIf the temperature at any room sensor or control sensor gets lowerthan the "Warning Low Limit" setting, an alarm will come on withthe delay explained above. This setting is an absolute setting anddoes not refer to the control setpoint.
Defrost Warning DelayAfter a defrost cycle the temperature might take longer to stabilizeand the normal warning delay turns out to be too short. For thisreason the "Defrost Alarm Delay" setting adds on to the normalwarning delay after defrosting.
Alarm:Warning relayde-energized
Functional Description
In order to avoid switching errors caused byinterferences, the controller delays any relayenergizing by 5 seconds. De-energizing is not delayed.
Control Sensor
In the mode page you will find the parameter "Control Parameter"which defines the sensor to be used for the temperature controlfunction. Here you can select ‘room sensor’, which is the normalmode of operation, or ‘defrost sensor’ (evaporator sensor, Air-Out-Sensor), which is used in special applications.
Cooling
Cooling is controlled by switching the output relay contacts ONan OFF. In case of power loss or other controller defects theoutput contacts must switch in a position which is safe for theapplication. For this reason we are using the N/O contact inrefrigeration applications (fail-safe: open contacts). In freezingapplications we use the N/C contacts (fail-safe: closed contacts).The type of application is to be selected in controller configuration(‘Cooling Mode’ in mode page).The setpoint is always the ‘cut-out’ point. The output cuts in againwhen the sensor value exceeds the setpoint by the selectedhysteresis (switching differential) value.The output can be disabled remotely via the network.
Analog Output
The TKP / TKC contains an analog output which can be used forregulation or to control an external display. The signal is availableas a DC-Voltage or a DC-Current-Signal. With the parameter"Analog Output" the range of the output signal can be isolated.Because both outputs are treated equal by the hardware"0-100%" is equal to 0-10V resp. 0-20mA,"20-100%" is equal to 4-20mA bzw. 2-10V.
PI-Control
Sometimes, when the cooling media is water or a water/glycolmixture, the cooling flow is controlled by a valve with progressive(continous) action. For this reason you can use the PI-Control.This function is available for the 1st channel of the controller only.The control action is ‘PI’ (proportional-integral) in order to avoidany steady off-set from setpoint. To realise this analog controloutput, the "Analog Output Parameter" in the mode page must beset accordingly and the parameters "Ch 1 Proportional Band" and"Ch 1 Integral Time" in the settings page are to be adjusted to fitthe requirements of the control circuit.
Transmitting an actual value
The analog output can be used to connect external displays,protocol systems or similar. If the "Analog Output Para(meter)" isset to ‘Actual Sensor Value’, the analog output corresponds to a-50....+100 °C range.The voltage and current outputs can be either 0...10 V and 0...20mA, if the "Analog Output" parameter is set to ‘0...100 %’, or 2...10V and 4...20 mA, if the parameter is set to ‘20...100 %’.
Secondary (2nd) Setpoint
You can use the controller with two (2) sets of setpoints, where thefirst (1st) setpoint is used during times of normal operation and thesecond (2nd) setpoint with a higher temperature is used duringnight times for energy savings or with a lower setting for shockfreezing periods. Both setpoints can be edited in the ‘Settings’

Evaporator Fan Control (Versions E, F and N only)
Versions E, F and N of the controller are equiped with a fancontrol output relay. The fan is controlled from the N/O inrefrigeration mode and from the N/C contact in freezing mode.The fan operation mode is selected in the ‘Mode’ page. You canselect either ‘permanent’ mode, where the fan runs continouslyand stops only during electric defrosting, or select ‘intervall’,where the fan runs during cooling periods only.There is a close connection with the ‘Defrost Type’ parameter.With this parameter you can select either ‘Electric’ defrosting(fan stops during defrost period) or ‘Free Air’ defrosting (fan runsduring defrost period). The start-up time delay for the fan afterdefrosting is set with para-meter "Fan Delay" in the‘Settings’ page.

PermanentOperation
This mode is mainly used on refrigerated shelfs,refrigerated display counters and chest freezers,where the fan runs even during defrost.Using controller types without a fan output, yourun the fans directly from the mains. Using acontroller type with controlled fan output (versionE, F or N), you can run the fan from this output. Inthis case you select a "permanent" fan mode and"Free Air" defrosting even if you have an electricheater connected to the defrost output.
This mode is mainly used on walk-in refrigera-tors. If parameter ‘Fan Mode’ is selected "inter-vall" and ‘Defrost Mode’ is "Free Air", the fan willrun when cooling is on and during a defrost cycle.
This mode is mainly used with walk-in refrigera-tors and walk-in freezers. If parameter ‘Fan Mode’is set to "intervall" and parameter ‘Defrost Mode’set to "Electric", the fan runs when cooling is on.The fan is disabled during defrost periods andcomes on after defrost with a time delay which isset with the ‘Fan Delay’ parameter. Please notethat the fan output contacts change with theapplication (refrigeration/freezing).
If ‘Fan Mode’ is selected "permanent" and ‘DefrostMode’ set "Electric", then the fan will runcontinously and stop during a defrost period only.The fan comes on after defrost with a time delaywhich is set with the ‘Fan Delay’ parameter.Please note that the fan output contacts changewith the application (refrigeration/freezing).

Defrosting
The controller is equiped with one or more relay output(s) forcontrolling an electric heater for defrosting the evaporator(s).The parameter ‘Defrost Type’ allows you to select either "Electric"or "Free Air" defrosting. This parameter works in close connectionwith the ‘Fan Operation’ parameter (see above). A defrost cycleis initiated by either the built-in timer or a remote contact via amains voltage input. A manual initiation via the keyboard ispossible at any time.An electric heater for defrosting is run from the N/O contact(s) ofthe defrost output relay(s) independent from the application(refrigeration/freezing). Cooling is disabled during defrostautomatically.
Defrost Initiation
Note: Defrost can only be activated if at least onedefrost (evaporator) sensor is active and thetemperature is below termination temperature. If
no evaporator sensor is used, at least one defrost sensorinput is to be simulated with a fixed resistor of 1.3 kOhmsand set active. In this case defrost is terminated by time only.
Defrost Timer
A built-in timer allows you to program up to six (6) different timesfor defrosting within 24 hours. The parameters are named "DefrostTime #" in the ‘Mode’ page.The setting ‘24:00’ is ineffective and can be used for those timeswhich are not used for that specific application. If the parameter‘Defrost Mode’ in the Mode page is set to "external", the timerfunction is disabled.
Remote Defrost Initiation
There is a mains voltage input available for remoteinitiating a defrost cycle. The input signal must havea duration of minimum 2 seconds and not last longer
than the shortest possible defrost cycle. Make sure that the opto-coupler signal input is tied to Neutral with the correct terminal.The signal itself is a phase signal.
Defrost termination
Defrosting is teminated for each defrost output individually by thecorrespondent defrost (evaporator) sensor. The defrost term-ination temperature(s) is set with parameter ‘Defr Temp Chan x’in the 'Settings' page.A defrost cycle is completed as soon as all defrost outputs havebeen reset or the safety time has expired. Now cooling is enabledagain. Defrost safety time is set with parameter "max Defr Time"in the 'Settings' page.
Cooling Delay
With 'Cooling delay' (settings page) you can set a duration wherethe solenoid valve(s) are disabled after defrost termination. Seethe remaining time at 'Remain cool del' (actuals page).
Defrost disabled
The controller disables defrosting for a period of 15 minutesafter a defrost cycle. During this period no defrost can beinitiated by any method.Disconnecting the controller from supply clears thedisablement.
Manual Defrost
Defrosting can be initiated by setting the value of parameter"Manual Defrost" (Setting page) to ‘1’.
Demand Defrost by Optimizing Method
With every requested defrost cycle the controller detects theactual period of time needed for melting the icing at the evaporatoraround freezing point. This time has a dependent relationship onthe number of defrosts needed per day or, with other words, howmany of the programmed defrost events can be skipped. Theresult of this calculation is displayed under parameter "n/o Defrignored" in the Mode page. A manually initiated defrost cycleclears this memory and starts a new calculation.
Demand Defrost by Differential Method (version F only)
This defrosting method uses two (2) additional sensors whichsense the differential temperature across the evaporator. Thisdifferential increases with increased icing.At a pre-set amount of icing (temperature differential) which is setwith parameter "Demand Defr Diff" in the 'Settings' page, thecontroller starts a measuring cycle for a certain period which isset with parameter "Dem Defr Period".If, during this period, the differential reading keeps its valueabove setting, the controller puts a demand signal into itsmemory (displayed under parameter "Demand Defr stored").Any stored defrost demand results in initiating a defrost cycle atthe next available defrost time (timer) or upon activating thedefrost signal input.For achieving good results with this demand defrost method thetwo additinal sensors must be placed carefully as explained inchapter ‘Sensor Positioning’.

Timer(internal)
Remotecontrol
In ‘frame heater’ mode the ON settings of the timerparameters disables the relay output (to save energyduring over-night operation) to be enabled again withthe OFF setting.To enable the timer function the external optocouplercontrol input must be connected to phase.
Both timer settings "2nd Setting ON" and "2nd SettingOFF" should be set to ‘24:00’.If the optocoupler input is connected to mains voltage(phase) the pulsed relay output is enabled (day-operation).If the optocoupler input is open, the frame heater relayis disabled.

Additional Functions
Versions A,C,F, I. K, L and M are giving you a choice of selectingone of two additional functions under parameter "Add Function"in the ‘Modes’ page. Both functions can be controlled by either aremote contact or the internal timer:
Roller Blind
Selecting the ‘Roller Blind’ function activates the relay output foropening and closing the roller blind(s) automatically. A defrostoverrides this function and opens the roller blind(s) for the defrostperiod.
The timer parameters "2nd Setting ON" and "2ndSetting OFF" are activating not only the secondarysetpoint(s) but have also an effect on the roller blind/frame heater output relay.If ‘roller blind’ mode is selected, the ON setting runs theroller blind in closed position and at the OFF settingtime the roller blind opens again. The optocoupler inputmust be connected to mains voltage (phase).
If the optocoupler input is connected to mains voltage(phase), we are in the ‘day’ mode. This results in de-energizing the relay when ‘Roller Blind ’ is selected andrunning the blind(s) open via the N/C contact. An openinput runs the roller blind(s) shut via the N/O contact.In the frame heater mode the output relay is activatedwith voltage to the optocoupler input (day) and totallyinactivated when the input is open (night).To avoid interference by the internal timer, both timersettings "2nd Setting ON" and "2nd Setting OFF"should be set to ‘24:00’.
Frame Heater
Choosing ‘FrameHeater’ activates arelay output forcontroll ing theenergy to the frameheater with a certain"frequency" and"pulse width" (modespage).The parameter"pulse width" meansthe heating durationin % of the frequency.

Controller OFF
Sometimes it is necessary to switch off cold storages completely including the controller. But if the controller works in a network, thebus-master detects a malfunction and generates an alarm.If the optocoupler input 'Controller OFF' is connected to phase, all regulation and control functions are disabled. The actual displaysare working properly, but no alarm will be activated.
'Security Chain' Control
The TKP versions M and N, which are suitable for single compressor applications, are monitoring the security devices (security chain)of the compressor. Normally the optocoupler input is connected to phase. But if the input is open, the cooling and the fan (version N)are switched off, a defrost period is terminated and a new defrosting impossible. The alarm relay will be activated. It is possible toset a delay time with parameter 'safety chain delay' (settings page).
Single Compressor Mode
The TKP-versions M and N are optimized for single compressor applications. This versions are containing a parameter called 'comproff time' which describes the unattended time of the compressor after running. The remaining time is displayed with 'Rem Compr Pause'(Actuals page).
Day-Counter
Every TKP is counting the time during he is switched on and stores the value in his memory. This value can be read only by a bus-master via network.
Summer/Winter Switching
The built in real time clocks are containing an automatic summer / winter switching. With the parameter 'summer / winter sw' the rulesfor this function can be changed or switched off.
Technical Manual TKP / TKC valid for Software Vers. 970225/1sha Page 16
Each controller in a network has its individual ‘adress’ which is set underparameter ‘Adress in Netwk’ in the ‘Modes’ page. This adress is necessaryfor selecting the right controller when a data message is transmitted on thenetwork bus. If the controllers are used outside a network, the adress andassignment parameters are of no importance.
Remote control of equipment andparameters
Your requirement:No local PC, no data logging. Youwant to get alarm messages fromyour equipment and you want toremote control the devices.You need:The communication module BSA 3000and a modem.The BSA-3000 module has the duty tocontrol the modem and tocommunicate with E-LINK. If there isand alarm, the BSA module istransmitting a message automatically.
There are two ways to communicatewith this E-LINK-"Network":
Central parameter editing and datalogging
Your requirement:You want to log individually selectedparameters (temperatures, switchingevents, etc.), remote control andgraphic analysis.
You need:A PC (IBM compatible) with one freeRS-485-interface or a PC with a freeRS-232-interface and a SSC interfaceconverter, the software MMA95 and aprinter.Communication with your office-PCis possible with a modem.
There is a Central Processing Unit (VPR 3000) available which controls upto two (2) cooling compound systems and that can network a number ofup to 64 controllers (TKP or TKC), which are working as 'intelligent slaves'.This central unit can be operated remotely too.
When a TKP or TKC network is supervised by a VPR 3000 central unit,there is a possibility of assigning each controller to a certain compound(refrigeration / Freezing) with the "Compound R/F" parameter in the ‘Mode’page. This enables the central unit to close the solenoid valves via therelated controllers in case of failure in a compound.
TKP/TKC-behavior during a compound system jammingIf he is assigned to a certain compound and a disturbance occurs, the TKPresponds as follows:- The solenoid valves were closed- The fan is switched off- A defrosting will be terminated. A new defrost period is only possible if the
compound jam is removed.To see if this function is released, look at 'Solenoid Valve' ('Modes' page).
Data transmitting disturbances / CPU (VPR) failureIf the controller gets no new informations from the central processing unit,he continues working with the actual values.If there was an order from the CPU to close the solenoid valves and atechnical defect interupts the data transmitting for more than 30 minutes,the TKP/TKC ignores this order and begins to work normally.If data transmitting is possible again and the CPU order is always valid, thesolenoid valves will closed again immediately.
E-LINKThese controllers can be networked together with other models from the‘3000’ controller series. For this duty ELREHA has developed 'E-LINK'.E-LINK is a two-wire bus-system based on the RS-485-Standard. With E-LINK up to 78 Controller can be assembled.

Operation / Control Elements
Operating the controller is very easy.
Four (4) keys allow you to read and edit all parameterswhich are displayed on a large backlit LCD panel.The parameters are shown uncoded.
The device contains no more control elements likejumper or DIP-switches.
Programming
All parameters are listed in three (3) pages: The ‘Actual’ page withall actual values, the ‘Settings’ page with the setting parameters,and the ‘Modes’ page with the initial settings and functionalmodes.
When no key is pres-sed for about 5 minu-tes, the display showsthe first parameter inthe ‘Actual’ page.
To edit a certain pa-rameter, you selectthe page with the"PAGE" key.
Using the "ñññññ" and "òòòòò"keys you can scrollthrough this list to findthe parameter.

To edit the parameter value you must first press the "PROGramming"key until the display starts flashing. Now you can edit the value ortoggle through a cyclic field by pressing the "ñññññ" and "òòòòò" keys.Pressing "PROG" again brings you back in normal mode and storesthe new value.The "ñññññ" and "òòòòò" keys, when pressed momentarily, change thedisplay by one step; continous pressing lets the display run with acertain speed.
Unauthorized Changing of Parameters
To avoid changing parameters by unauthorized per-sons, the PROG function is locked until the correct code waspunched in. The parameter ‘Identification’ asks you for enteringthe correct code. This code is related from the actual time of theday as the sum of the hour (0 to 23) plus ‘10’.
As an example: At 9:35 a.m. the code is 9 + 10 = 19.At 9:35 p.m. the code would be 21 + 10 = 31.
NOTE: You can find the actual time as a parameter in the ‘Mode’page. Correct if necessary.
If you have pressed no key for 5 minutes after punching in thecode, the keys are locked again automatically.Temperature control ‘setpoints’ and the ‘Manual Defrost’ need notto be unlocked..
Technical Manual TKP / TKC valid for Software Vers. 970225/1sha Page 18
Installation / Getting Started
Temperature sensors generallyThe used temperature sensors are identical (TF 201). You will findinformations about sensor positions in chapter 'sensor positions'.
Before applying voltage to the controller, make surethat all wiring has been made in accordance with thewiring diagram in this manual and is fitting the
application. Sensor harnesses may be up to some hundred metersin length, but shielded cable must be used with one end of theshield connected to ground. This avoids irregular switching eventscaused by electro-magnetic interference.Connect the ‘PE’ terminal carefully to ground because otherwisethe operation of the internal noise filter will be disabled.
The sensors used with this controller are moisture-proof but theyare not designed for being immersed in water for a long period oftime (not pressure-proof).
Replace old TKP 1901 types: see page 22
Upon applying voltage to the controller, the display readsthe actual temperature of room sensor # 1 (1st parameterin ‘Actual’ page) and the display backlight is off. Punching
any key turns the backlight on.
l Your first job is now to select the controller version. Press‘PAGE’ until the display reads 'TKP_3/TKC_19' (modespage) which is the first parameter in this page. The 2nd rowin display indicates the controller version. To change thisversion, press ‘PROG’ and the controller will ask you foryour identification (access code).Using the "ñññññ" and "òòòòò" keys, fill in the valid code (see chapter‘Unauthorized Changing ...’) and press ‘PROG’ again.When the parameter reading starts flashing, this indicatesthat you are in programming mode. The "ñññññ" and "òòòòò" keysnow allow you to select a version from several availableoptions. Upon pressing the ‘PROG’ key again, you leavethe programming mode and the new setting is stored.
The next step is to inform the controller about the sensorsto use.
l If you don‘t need all available sensors, you can cancel thefunction of a sensor with the "Correction Sensor # x"parameter. If the sensor is ON, this parameter shows eitherthe correction factor (set in the ‘Actual’ page) or a sensorfailure. In programming mode you have an OFF choicewhich deactivates the sensor completely.
l Sensor corrections can be made in the ‘Actual’ page byediting each individual sensor reading. The resultingcorrection factors are listed in the "correctin factor"parameters of the ‘Modes’ page.
Now you have to fix the basic operation modes. You willfind the required parameters in the 'modes' page:
l defrost type "Defrost Type"l fan operation "Fan Operation"l cooling mode "Cooling Mode"l defrost mode "Defrost (Init) Mode"l additional function "Additional Function"l predefine the control sensor "Control Parameter"l operation mode "Operation Mode"
etc.
l Now the controller has its initial configuration. The temperatureand time delay settings are made in the ‘Settings’ page by thesame programming (editing) procedure.
l Check the "Actual Failure" parameter in the ‘Mode’ pagefor being cleared. Otherwise correct failure which might becaused by incorrect settings or other hardware faults.
Failure Codes
Failures which are still actual are listed under parameter "ActualFailure" in the ‘Mode’ page. Sensor failures are additionally listedwith the sensor in the ‘Actual’ page.Failures of the past are listed with time and date of occurrence inthe "Historical Failure" list in the ‘Mode’ page.
"----" ......................... no failure"Init" ......................... first initialisation of the controller or data lost"Hard" ...................... hardware failure"main" ...................... loss of supply"SeCh" ....................

Detailed informations about wiring and EMC-problemsyou will find in our actual product catalogue.
Attention:
The first evaporator sensor cannot switched off. If there shouldbe no evaporator sensor in your application, you have to installa termination resistor (1,2K / TF 201 selected or 820 ohms / Pt1000 selected) instead of the first evaporator sensor.
Technical Manual TKP / TKC valid for Software Vers. 970225/1sha Page 19
Sensor Positions
The controller needs to have temperature input information which is as correct aspossible. For this reason positioning of sensors must be made with a certainknowledge of the control loop. Different applications require different sensor positions.In the following we are giving some examples for sensor positions:
Refrigeration devices with ‘Free Air Defrost’
These cooling divices usually have no defrost sensor(s). De-activate the correspondentinputs by setting the ‘Corr Sensor’ parameters OFF. The defrost time is set with the‘Defr Time’ parameter in the ‘Setting’ page.
Cooling devices with ‘Electric Defrost Heater’
Defrosting with electric heater(s) or hot gas defrost needs to be terminated bytemperature. For this reason each evaporator is equiped with an individual defrostsensor. In applications where the evaporators are serving different physical spaces,each area can have its own room sensor for temperature warning purposes.
Walk-in Coolers
The room (control) sensor is fitted in the return air. The defrost (evaporator) sensorcan sit between the evaporator fins or at the side wall of the evaporator. Make surethat the sensor doesn‘t touch the heater or any piping with hot gas defrost.
Refrigerated Display Counters
Although placing the room sensor in the return air would be the correct solution, inpractice the sensor is placed in the outlet air from the evaporator. If for monitoringpurposes the room temperature is to be sensed, use a free room sensor. The defrost(evaporator) sensor can sit between the evaporator fins or at the side wall of theevaporator. Make sure that the sensor doesn‘t touch the heater or any piping with hotgas defrost.
Refrigerated Shelfs
These devices normally have a thermometer built-in from the equipment manufacturer.Placing the room (control) sensor the same location with the sensor of the thermometergives best controlling results. The defrost (evaporator) sensor -if used- can sitbetween the evaporator fins or at the side wall of the evaporator. Make sure that thesensor doesn‘t touch the heater or any piping with hot gas defrost.
Chest Freezers
Since these devices seem to be frequently overloaded by the user, the control sensorin the return air is not always representing the actual temperature of the goods. Tohave always save conditions, in practice the device is controlled from the evaporatoroutlet air temperature.The defrost (evaporator) sensor can sit between the evaporator fins or at the side wallof the evaporator. Make sure that the sensor doesn‘t touch the heater or any pipingwith hot gas defrost.Some applications are using just one (1) sensor in the air outlet for controlling anddefrost termination. In this case the "Control Mode" parameter in the ‘Mode’ pagemust be set to ‘Defrost sensor’.
Reach-in Freezers
The room (control) sensor is fitted in the return air. The defrost (evaporator) sensorcan sit between the evaporatir fins or at the side wall of the evaporator. Make surethat the sensor doesn‘t touch the heater or any piping with hot gas defrost.In master/slave applications, each single device has its own defrost sensor and aroom sensor. The room sensor in the master unit is the control sensor for thecomplete set and the room sensors in the slaves are used for temperature warning.
Demand Defrost by Temperature Differential
This method uses two additional sensors to record the temperature differentialacross the evaporator. The ‘cold’ sensor is mounted directly to the 2nd or 3rd elbowof the evaporator tube and the ‘warm’ sensor sits in the evaporator outlet air. Roomand defrost sensor are placed in the same way as explained in former paragraphs.

Failure Locating
This Technical Manual was set up to our best knowledge und we guess having covered all important factors around the ‘TKP 3000’controller.If, nevertheless, you run into problems, we have listed below some common questions which might help you in trouble shooting:
The display shows unreasonable temperature readings:l Check sensors for correct type and connections. Sensors are of same type (TF 201) and should read a resistance value of
2000 Ohms @ 25 °C and 1645 Ohms @ 0 °C.
No regulation functions:l Is the input 'controller off' connected to phase ?l Single compressor versions: Is the security chain open ?
Controller doesn‘t defrost: Check following parameters:l is ‘time of the day’ set correctly ?l are ‘defrost times’ set ? (no defrost at 24:00)l are defrost sensors below ‘defrost temperature’ setting ?l notice that defrost is disabled for 15 minutes after prior defrostl are ‘defr mode’ and ‘defrost type’ set correctly ?l is wiring in accordance with selected mode and type ?l check parameter ‘defrosts ignored’ for number of defrosts to be skipped when optimizing method was selected !
No manual defrost:l check for disabled period (15 minutes after defrost)
Room temperature warm but no cooling:l check for correct setting of ‘cooling mode’ and corresponding wiring connections !l room sensor and defrost sensor mixed up ?l check for active setpoint (day / night) !l if networked: has central unit disabled the solenoid valve ?
Alarm stays ON:l are sensors and wiring correct ?l setpoints and warning offset correct ?l unused sensors switched OFF in ‘sensor correction’ parameter ?
Fan doesn‘t come ON after defrost:l are ‘fan mode’ and ‘defrost mode’ set correctly ?l is ‘fan delay’ set to a reasonable time ?
Defrost is not terminated by temperature:l check for mixed up sensors !l is the defrost sensor(s) activated in ‘sensor correction’ parameter ?l defrost (safety) time set too short ?
Night setpoint (2nd set) active all time:l check OK 1 input (connect to phase and corresponding terminal to neutral) !l check timer settings !
Data lost ( INIT ):l is PE terminal connected to ground ?l sensor leads shielded and shield connected to ground ?l Please check over your installation conditions, informations are available in our actual product catalogue.
