Please read before Start-up

• Limit of Application: This product is not designed nor manufactured for use in equipment or systems that are intended to be used under such circumstances that may affect human life. For applications requiring extremely high reliability, please contact the manufacturer first

• Electrical installation and putting into service must be done from authorized personnel.

• Please note the local safety instructions !

• Before installation: Check the limits of the controller and your application. Before starting up we recommend you to read the following instructions for use, since only by doing so you can avoid damage or malfunction and you will benefit all the advantages offered by this product.

• During installation and wiring never work when the

electricity is not cut-off !

• If the units should be networked, never connect the secondary coil of 12/24V transformers to PE !

• To control servo drives/actuators, a TAR 1260 must be supplied by a separate transformer

• Mounting the controller close to power relays is unfavourable in case of the electro-magnetic interference.

• Before applying voltage to the controller: Make sure that all wiring has been made in accordance with the wiring diagram in this manual. Check, if the supply voltage corresponds to the value printed on the type label.

• Connect the ‘PE’ terminal carefully to ground because otherwise the operation of the internal noise filter will be disabled.

• Respect the environmental limits for temperature and humidity. Outside these limits malfunctions may occur.

• Never operate unit without housing.

• Observe the maximum admitted current rate for the relays (see technical data). Compare with the peak startup current of the controlled devices (valve, fan, compressor, heater..)

• Sensor cables may be up to some hundred meters in length. Use shielded sensor cable only. Don’t install them in parallel with high-current cables to prevent inductive interference. A cross section of min. 0,5mm² is sufficient.

• Shielding has to be connected to PE at the end near the controller

• All used temperature sensors must be identical. Never use PTC (TF 201) and PT1000 (TF 501) mixed. This will not work.

• TF-type sensors are moisture-proof but they are not designed for being immersed in water for a long period of time (not pressure-proof). In such a case, always use dipfittings.

• Be care that the wiring of interface lines meets the requirements

Unlock Keys

To prevent un-authorized persons from editing parameter values, there is a locking function which allows only the most important parameters to be changed at any time. All other parameters must be unlocked beforehand. This means that at parameter P43 a certain value is to be set (see parameter listing) :

Press key "P"............. parameter number appears

Use "ñ/ò" ................. select code parameter (P43)

Press "P" again ......... parameter value appears

Use "ñ" ..................... set value to --88--

Press "P" again ......... value is stored, back to parameter no.

If no key is hit for about 4 minutes, the access code is cancelled and the editing function is locked automatically.

Error Display / Error Behaviour

Display shows "oFF":

The controller unit is disabled via digital input OK1 or via network interface (DDC). If the controller has been de-activated via interface before, it can be waked up manually by holding the 'ò'-key for more than 3 seconds.

Display flashes, without minus sign:

Using temperature sensors= O

ne of the two sensors is broken or wrong type Current input = > 25mA

Display flashes, with minus sign:

Using temperature sensors = O

ne of the two sensors has short-circuit or wrong type Current input = < 2mA

All control relays (K1 + K2) switch off immediately. Additionally to the flashing display, an alarm delay runs (P31), after this timer is run run down, the alarm relay (K4) will be activated.

If sensor errors occur, P31 is always < 1min.

Functional Description

Sensor connection

The controller operates either with temperature sensors of the types TF201 (PTCs) and TF 501 (PT1000) or with a 4...20 mA signal. The input will be selected by parameter P26. The selection of inputs and sensors depends on your requests:

Temperature Controller

: For temperatures < 80°C use sensors TF 201 or TF501. For temperatures > 80 up to 300°C you must select an appropriate Pt1000 sensor.

Pressure controller

4...20mA from pressure transmitter

Humidity controller

4...20mA from humidity transmitter

Operation modes The controller can be configured for different

operating modes (with parameter P14):

P14 = 1

: 2 control sensors Sensor 1 effects to setpoint 1, sensor 2 effects to setpoint 2. So you realize 2 independent single stage temperature controllers in one unit. In this mode the

4...20mA input is de-activated.

P14 = 2

: 1 control sensor or transmitter

(dual stage control) Sensor Input 1 or the 4...20 mA Signal Input effects to both setpoints (P03 / P04), Sensor Input 2 is de-activated. P03 is an absolute value, P04 can be also relative (adjustable by P05).

P05 = 1: Setpoint 2 (P04) is an absolute

value (used for dual stage control

with individual setpoints) P05 = 2: Setpoint 2 (P04) is a relative value

(used for dual stage control with

neutral zone, that means that P04

will be shifted the same amount if

P03 is shifted)

P14=3

: 1 control sensor + 1 sensor for

setpoint shift Sensor 1 effects to setpoint 1 (P03), sensor 2 may shift setpoint 1. The 4...20 mA input is de-activated. With this, you realize e.g. an outdoor temperature guided control. P19 is the limit from which a rise or lowering (shift) becomes possible, P20 is the range of the shift, P21 the amount of the shift.

Example:

- Control Setpoint 1 P03 = 10°C

- Limit value P19 = 20°C, that means increasing starts with 20° at sensor input 2, below that value there's no shift.

- range of shift

P20 = 5K

, that means shift range is 25K in total, above 25°C at sensor 2 maximum setpoint shift.

- Size of shift

P21 = 8K

, from 25°C the control setpoint is P03 + 8K, in this example = 18°C.

P18 shows the current shift amount. This value is a sum of the day/hight shift and the setpoint shift.

P14 = 4

: 2 control sensors, cyclic defrost function is active. Sensor 1 effects to setpoint 1, sensor 2 effects to setpoint 2. With this configuration you realize two independent singlestage controllers in one unit like above, but parameters 20/21 get a different function. Cooling via setpoint 1 (i.e. the output effected by setpoint 1) is disabled in specific time intervals to enable air flow defrost. The 4...20 mA input is deactivated.

Actual value display / status display

With temperature sensors:

Temperatures can be displayed in °C or °F selected by parameter P26 (= sensor type switch). The resolution is 0.1°C (or 0,2°F). While operating with temperature sensors, P01 shows the actual value of sensor 1. You also come back to this display at P01, if another parameter is selected and no key is pressed for about 4 minutes. In operation modes 1, 3, 4 and 5 P02 shows the actual temperature value of sensor 2.

With 4...20 mA transmitters

: In op-modes (P14) 2 and 5 the “4...20 mA”input is activated and can be read at P01. The standard current signal can be delivered by an 4...20 mA source or appropriate transmitter.

Adapting of humidity and pressure transmitters, display correction

A transmitter delivers the measured value as a

4...20 mA signal. With parameter P30/P29 the measuring scale will be preset.

Example 1: Humidity transmitter,

Range 0...100% r.H. P29 = 100, P30 =0

Example 2: Pressure transmitter,

Range –0,5 ... +9.0 bar P29 = 9,0 and P30 = -0,5

With P27 the display of actual value P01 can be corrected, with P28 a correction of the value displayed by P02 is possible.

Switching hysteresis For the setpoints P03 / P04 you can fix a

switching hysteresis with parameters P12 and P13. The position of the hysteresis (above/ below the setpoint) depends on the selected relay switching mode (P07 resp. P08).

Setpoint limits To prevent the setpoints being set to an invalid

value (e.g. not below 0°C), the range of P03 / P04 can be restricted by parameters P10 and P11.

Day / night shift - 2nd Setpoint E. g. to save energy it is possible to work with

other setpoints at any time. By parameter P06 an offset value can be set on which all setpoints will be shifted if Digital Input OK 1 is activated.

Temperature- resp. Limit Value Alarm If the value measured with sensor 1 or the

delivered 4...20 mA signal leaves the range preset by parameters P32 and P33, then an alarm relay and a buzzer will be activated after a delay timer (P31) is run down. P22 shows the remaining time of the alarm delay timer. P33 (lower limit) is an absolute value and P32 is always a relative value coupled to the current setpoint (P03 + eventually shift).

Relay switching characteristic The switching characteristic of relays K1 and

K2 are defined by parameters P07 and P08. The following options can be selected:

1= Refrigeration (Standard)

Used for standard applications (e.g. temperatures above 0°C). The load would be switched by the NOcontact.

2 = Freezing (DF)

Used for temperature applications below 0°C. The load would be switched by the NC-contact, this enables that the load will be switched on permenantly in case of mains loss or controller defect.

Note: not usable for relay 2 at type 1260.

3 = HT (Heating)

Usable for heating applications. Load would be switched off in case of mains fail or controller defect. Use NO-Contact.

4 = Cycling

Quasi-Proportional Control with cycling relay. Usable for heaters or certain valves. Here a range will be defined within the relay will cycle. The relay's ON/OFF ratio (cycle ratio) depends on control deviation. The period duration will be set by P40. With P40=1 the period duration is 16 seconds, with P49=2 the duration is 32 seconds, and so on.

P16 defines the Xp-range where relay 1 cycles within. The upper limit of this range is:

P03 (setp.1) - P12 (hyst.1).

The lower limit is built of:

P03 (setp.1) - P12 (hyst.1) - P16

If the signal reaches the hysteresis range P12, relay 1 remains OFF permanently, below the lower limit relay 1 remains permanently ON (e.g. for heating, humidifying).

P17 defines the Xp-range where relay 2 cycles within. The lower limit of this range is:

P04 (setp.2) + P13 (hyst.2).

The upper limit is built of:

P04 (setp.2) + P13 (hyst.2) + P17

Above the upper limit, relay 2 remains permanently ON (e.g. for refrigeration, de-hu midifying), below the lower limit relay 2 remains OFF.

Alarm relay characteristic Parameter P09 defines if the alarm relay is

affected from the actual value P01 or P02 and whether the alarm relay is activated (active) or de-activated (passive) if an alarm occurs.

Minimium idle time If a relay has been switched OFF, it can be

activated first after timer P15 is run down. If the switching characteristic is set to 'cycling' this function is de-activated. Parameters P23 and P24 show the remaining time until the relays will switch ON again.

Example for a cycling heater:

Switching char. ..... P07 = 4

Setpoint 1 ............. P03 = 8°C

Hyst. setpoint 1 .... P12 = 1K

P-range relay 1..... P16 = 4K

8°C = relay OFF permanently 7°C = relay OFF permanently 6°C = relay cycles, 25% ON,

75% OFF 5°C = relay cycles, 50% ON, 50% OFF 4°C = relay cycles, 75% ON, 25% OFF 3°C = relay ON permanently

Defrost Function In operation mode 4 (P14=4) a simple defrost

function can be used. This function suppresses (in adjustable intervals) the switch-on of relay 1 to enable an air circulation defrost. The parameters P20 and P21 have another significance in this mode. P20 defines the defrost cycle, P21 the defrost duration. After power-on of the unit the defrost cycle time (P20) runs down first, before a defrost can start. To prevent a temperature alarm while a defrost event, P31 must be lengthened eventually. A defrost can be started and stopped manually while the actual value is being displayed, a running defrost event is indicated by an LED (see 'operating').

Digital Input

With the Digital (optocoupler) Input OK 1, normally connected to mains voltage, a function (preset by P34) can be activated if mains will be disconnected from this input.

The type TAR 1260 has no optocoupler input, the function will be activated by opening an external, isolated contact connected to terminals 18/19.

Never connect mains voltage to this terminals !

P34 = 0 Digital Input is de-activated P34 = 1 No voltage (1260: ext. contact open) at Digital Input 1

switches to the 2

/night-setpoint. Setpoints will be

increased / decreased by the value of P06.

P34 = 2 No voltage (1260: contact open) at Digital Input 1 starts

an external alarm. After P31 is run down, the internal buzzer and the alarm relay will be activated.

P34 = 3 If ther is no voltage (1260: contact open) at Digital Input

OK 1 all control functions will be disabled, the display shows 'oFF'. The unit can only be reactivated by connecting the input to mains again (1260: external contact closed).

An adjustable delay (P35) is effectual before one of the functions above will be started.

Networking of TAR-controllers

All TAR controllers can be networked via their builtin RS-485-interface. This network can be controlled by a host unit. Normally this host is a PC with a qualified software which allows remote control of units and recording of all parameters.

Because all units are connected parallel on the data cable, every unit has its own network address (P42) to ensure a specific communication.

The communication speed is fixed by P41, the default value is 9600 Baud.

If networked controllers (1xxx types only) are supplied by one transformer only and the single positions must be switched off, use double-pole switches only. If not, the unit will be supplied partially over the shielding of the data connection and continues operation, depending on the secondary voltage of the transformer. Please note: If a unit is not supplied, the PCsoftware notifies a unit breakdown !

A better way is not to switch-off the supply voltage but to disable the unit by Digital Input.

Important: Never connect the secondary coil of the transformer to PE!

The TAR-x260 owns an analog output with a 0-10 V DC-signal. Because of its scalability it can be used both for deliver an actual value 1 image or as a proportional control resp. PI-control output.

P36.... fixes the actual value the analog output delivers 10V DC.

P37.... fixes the actual value the analog output delivers 0V DC.

P38.... Fixes the I-part of the output signal in 5 steps from appr.

0,25...4 minutes or switches it off. Analog Output Operation Mode P39 fixes the operation mode of the output. P39 = 0 Output is de-activated.

P39 = 1 Output effects proportional, that's to say increasing

actual value -> increasing output voltage P36/P37 are absolute values.

P39 = 2 Output effects anti-proportional, that's to say

increasing actual value -> decreasing output voltage P36/P37 are absolute values.

P39 = 3 Output effects proportional, that's to say increasing

actual value -> increasing output voltage. The values set by P36/P37 effect relative to the current setpoint (P03 + shift).

Example:

P36 = 10°C, P37 = -10°C P39 = 3, P03 = 15°C, no current shift

Output-:

10V at P03 + P36 = 25°C

voltages

0V at P03 - P37 = 5°C

P39 = 4 Output effects anti-proportional, that's to say

increasing actual value -> decreasing output voltage. The values set by P36/P37 effect relative to the current setpoint (P03 + shift).

Example:

P36 = 10°C, P37 = -10°C P39 = 3, P03 = 15°C, no current shift

Output-:

0V at P03 + P36 = 25°C

voltages

10V at P03 - P37 = 5°C

Example Actual Value Image:

You have a remote display or similar which shows -50°C at 0V input voltage and +50°C at 10V DC.

P37 = "-50", P36 = "+10", P39 must be "1" .

Example Proportional Controller:

You want to control any device with 0-10V-input depending on pressure. You want it to be half open at 5.0 bar. If pressure descends the device should go more open, fully open from 4 bar. If pressure increases the device should closed, from 6 bar it must remain closed.

P37 ="4.0", P36 ="6.0", P39 ="2" Slow-down time / I-part P38 (slow-down time) fixes the influence of the I-part to the control

process. The amount of the I-part of the controlling variable is identical with the P-part and will be added. The full size of the I-part will effect after P38 is run down.

Example: - 10V U

out

at +10°C, 0V U

out

at -10°C

- aimed setpoint 0°C = 5V U

out

- current actual value 0°C

Actual value increases by 2K ->

rises to 6V immediately

TAR 1260 and Servo Drives / Actuators

Actuators work with 24V AC mostly and so you get the thought to supply actuator and controller from the same source. Unfortunately, supply voltage and control input are not isolated in actuators, this may destroy the TAR 1260. Because of this:

If a TAR 1260 must control a servo drive, the TAR must be supplied by an own, separate transformer !

Technical Manual Temperature-, Humidity-, Pressure-Controller TAR x260

Start-up example: Dual Channel Temperature Controller

Requirements: Cooling ON at +10°C/ OFF at +9°C, Heating ON at +1°C/OFF at +2°C, the

offset Heating/Cooling remains always equal, Overtemperture Alarm at +15°C, Undertemperature Alarm at 0°C, both after 30 minutes. The alarm relay works active-low. At a certain time the setpoint must be increased by 2K (night operation). The controller works with the temperature sensor TF 201. The customer must be prevented from adjusting the setpoint lower than 0°C.

• Please always note safety instructions on page 2!

If the TAR is switched ON, the display shows the value of sensor input 1.

Enter code number "70" at parameter P43

• P26= 1, Sensor Type TF 201 and display in °C

• P14= 2, Operating mode with 1 control sensor (F1) only Enter code number "88" at parameter P43

• P03= 9.0 (cooling setpoint, relay K1)

• P04= -7.0 (heating setpoint 7 K below P03, relay K2)

• P05= 2 (heating setpoint is relative value, coupled to the cooling

setpoint)

• P06= 2.0 (cooling setpoint will be increased by 2K while night operation)

• P07= 1 (relay K1 will be activated with rising temperature)

• P08= 3 (relay K2 will be activated with falling temperature = Heating)

• P09= 1 (alarm relay K4 will be de-activated with an alarm)

• P10= 15 (the setpoint cannot adjusted higher than +15°)

• P11= 0 (the setpoint cannot adjusted lower than 0°)

• P12= 1 (hysteresis of cooling relay, 1K)

• P13= 1 (hysteresis of heating relay, 1K)

• P31= 30 (alarm delay 30 minutes)

• P32= 5 (overtemperature alarm 5 K higher than cooling setpoint)

• P33= 0 (underemperature alarm at 0°)

• P34= 1 (digital input open = night shift)

• P35= 0 (night shift works immediately)

Display Correction The Actual Value Display P01 can be adjusted by P27, the Actual Value

Display P02 can be adjusted by P28.

Start-up example: TAR as Humidity Controller

Requirements: De-humidifying ON at 80% r.H., Moisten ON at 60% r.H., hysteresis 2%,

both setpoints are absolute values, no alarm, no night shift. The controller must work with the humidity transmitter FF 2520. No setpoint limitation for the customer. The customer want to read the humidity value on a remote display with 010V-input.

• Please always note safety instructions on page 2!

If the TAR is switched ON, the display shows the value of sensor input 1.

Enter code number "70" at parameter P43

• P26=5, Transmitters with 4-20 mA signal

• P14=2, Operating mode with 1 control sensor only Enter code number "88" at parameter P43

• P03=78.0 (de-humidify setpoint, relay K1)

• P04=62.0 (moisten setpoint , relay K2)

• P05=1 (setpoints are absolute values)

• P06=0 (no setpoint shift)

• P07= 1 (relay K1 will be activated by rising humidity = de-hum.)

• P08= 3 (relay K2 will be activated by falling humidity = hum.)

• P10= 100

• P11= 0

• P12= 2 (hysteresis for de-humidifying relay, 2%)

• P13= 2 (hysteresis for moistening relay, 2%)

• P29= 100 (display value with 20 mA current input)

• P30= 0 (display value with 4 mA current input)

• P34= 0 (Digital input disabled)

• P36= 100 (Analog output delivers 10V DC at 100% r.H.)

• P37= 0 (Analog output delivers 0V at 0% r.H.)

• P39= 1 (operating mode of analogue output)

Display Correction

The actual value display P01 can be adjusted by P27.

Installation hint:

If the measured values 'jump' check the following: Is the shielding of the sensor wire connected to PE near the controller unit? Is the PE terminal of the controller unit connected to PE? If the sensor wire is shielded correctly but the value on the display continues 'jumping', please try to solve the problem by removing the shield from PE and connecting it to a ground terminal of the TAR.
