Unlock Keys / Access code

To prevent un-authorized persons from editing parameter values, there is a

lockingfunctionwhichallowsonlythemostimportantparameterstobechanged

at any time. All other parameters must be unlocked as follows:

- enter access code before programming at parameter P41 or

- directly at the parameter to be changed. If a code no. is necessary the

display shows "C00". Set the matching code no. by the "/"-keys (70 or

88, see parameter listing) and confirm by "P".

If no key is hit for about four minutes, the access code is cancelled and the

editing function is locked automatically.

After entering of the code '70' the control functions will be disabled.

They will be restartet if the code will be changed manually (e.g. to 88

for other parameters) or will be resetted automatically after 4 minutes

without any press on a button.

Technical Manual TAR x700-2 page 3

Functional Description

Signal Input

The controller unit is able to work with the tempe-

rature sensor types TF 201 and TF 501 (Pt1000).

This must be preset by parameter P25.

Ranges:

P25 = 1 (TF 201).......-50...+100°C

P25 = 3 (TF 501/Pt1000).......-100...+300°C

Please note the specific temperature restric-

tions of the different sensor types (e.g.

-40...+80°C with standard-TF-types) and ask

for matching products if necessary.

Actual Value- and Status Display

Temperaturevaluescanbedisplayedin°Cor°F.This

will be preset together with the sensor type.

P01 shows the measured value of sensor 1.

If other parameters are selected, 4 minutes after

the last keypress the display switches back to P01

automatically. In operating mode 3+4, P02 shows

the measured value of sensor 2. In operating mode

'Differential control', P03 shows additionally the

differential value between sensor 1 and 2.

Display Correction

The Actual Value Display P01 can be calibrated by

P23, P02 can be calibrated by P24.

Operating Modes

The TAR controller knows 4 different operating

modes, which can be preset by P19:

P19 = 1: 3 Stages + Alarm.

In this mode

you realize a 3-

stage controller,

relay K4 works

as a closed cir-

cuit alarm relay,

sensor input 2 is

disabled.

The value of

sensor 1 will be

compared with

P04, P05 and

P06, the relays K1, K2 or K3 switch depending on

the deviation. P04 is always an absolute value, the

following setpoints can be either relative values or

absolute values (preset by P08).

Relative values = Stage switches in a specific

distance to the leading setpoint P04. If P04 will be

changed, the relative setpoints will be changed the

same amount.

P19 = 2 : 4-stage controller

Sensor input

2 is disabled

in this mode.

The value of

sensor 1 will be

compared with

P04, P05, P06

and P07, the

relays K1, K2,

K3 or K4 switch

depending on

the deviation.

Controlsetpoint1(P04)isalwaysanabsolutevalue,

the following setpoints can be either relative values

or absolute values (preset by P08).

P19 = 3 : Double 2-Stage Controller

Sensor 1 af-

fects on the

control set-

points P04/

P05 (= relays

K1/K2=control

circuit 1).

P04 is the lea-

dingsetpointof

control circuit

1, control set-

point 2 (P05)

can be either absolute or relative (P08). Sensor 2

affects on the control setpoints P06/P07 (= relays

K3-K4 = control circuit 2). P06 is the leading setpoint

of control circuit 2, P07 can be either absolute or

relative (P08).

P19 = 4 Differential Controller

Thecalculateddif-

ferential amount

from "sensor 1

minus sensor 2"

will be compared

with P04.

Relay K1 swit-

ches, if the pre-

set value P04 +

hysteresis P18

is reached. The

relay switches off

again, if the dif-

ferential amount

decreases and reaches P04. The stages 2 (relay

K2, P05, assigned to sensor 1) and 3 (relay K3,

P06, assigned to sensor 2), can work independly

as single stage controllers.

Relay K4 works as a closed circuit alarm relay.

Switching Hysteresis

With P18 you set a switching hysteresis, which

affects to all setpoints. The position of this hyste-

resis (above/below the setpoint) depends on the

selected switching characteristics (P10-P13) of

the single relays.

Setpoint Limits

To prevent that the final user adjusts the setpoints

to an inadmissible value, the setpoint range can be

limited by P16 and P17.

Real time clock

The integrated real time clock allows to change the

setpoints at specific times. The timer has a power

backup for about 10 days in case of power failure.

The time of the day and the date can be set with

parameters P35...P36.

Because the display has only three digits, the time

value comes in the following format:

Day-/Night Mode / Setpoint Offset

Initiation by real-time clock

With P14/P15 you can set a period of time within

all setpoints will be shifted by the amount of P09.

If not necessary, you can disable P14/P15 (display

shows "oFF").

Initiation by Digital Input

Digital Input OK 1 can also be programmed to

activate this offset (P29=1). An active 2nd setpoint

is indicated by a flashing decimal point.

Temperature Alarm

If the tempe-

rature value

measured with

sensor 1 ex-

ceeds the ran-

ge set by P27

and P28, the

alarm relay will

be activated

after the delay

timerP26isrun

down.

Parameter P21 shows the remaining time up to

an alarm.

P28 (lower limit) is an absolute value, P27 is always

a relative value in a distance to the actual setpoint

1 (P04 + potential shift).

Relay Switching Characteristic

The Switching Characteristic of the relay K1-K4 is

defined by the parameters P10...P13. The following

characteristics are possible:

1= Refrigeration (RF)

Used for standard applications (e.g.

temperatures above 0°C). The load would be

switched by the N/O-contact.

Actual value = setpoint + hysteresis: Relay on

2 = Freezing (FR)

The load would be switched by the N/C-

contact, this enables that the load will be

switched on permanently in case of mains

loss or controller defect.

Actual value = setpoint + hysteresis: Relay off

3 = Heating (HT)

Usable for heating applications. Load

would be switched off in case of mains

fail or controller defect.

Actual value = setpoint -hysteresis: Relay on

Minimum Idle-Time

If a load is switched off by a relay, this relay cannot

be switched on again before the time set with P20

is over. P20 affects all relay stages.

The indicator LED's of the single stages flashes

while this idle time runs.

The Minimum Idle-Time affects immediately after

power-on of the controller.

Digital Input

Digital input DI1 is normally connected to mains

voltage. If this voltage is interrupted, the function set

with P29 will be initiated after a time delay (P30).

P30 is adjustable within 0...99 minutes, but at '0' the

minimum delay is appr. 4 seconds.

P29=oFF Digital input DI/OK 1 is de-activated

P29=1 Control Setpoint 2 (night-setpoint) is

active. The setpoints increase/

decrease by the amount of P09.

P29=2 An external alarm is detected after

P30 is run down. LED 4 and the alarm

relay are activated after P26 has been

run down.

P29=3 Controller unit oFF. All control

functions will be disabled, the display

shows "oFF". This allows to switch off

the unit without an alarm message in

a network. Relays 1-3 are deactivated,

the alarm relay remains in a neutral

position.

Analogue output behaviour:

• Delivers 0V with op-mode

proportional (P34=1 or 3).

• Delivers 10V with op-mode

anti-proportional (P34 = 2 or 4)

P22 shows the remaining delay time of the digital

input.

Using the TAR 1700-2 this function must

bestartedbyopeninganexternal,potential

free contact connected to terminals 11/12.

Never connect mains voltage to these

terminals, danger of destruction! This

contact must be suitable for 5VDC/1mA.

TAR 1700-2 - Dimensions and Connection

Connection Example (simplified)

Voltage Output / Analog Output

The TAR contains an analogue 0-10V DC-signal

output. Because the output is scalable, it can be

used either to forward the actual value of sensor 1

(P01) or as a proportional /PI-controller output. In

differential control mode the voltage output depends

on the determined differential amount.

P31......actualtemperature(resp.differentialamount)

the output voltage delivers 10V.

P32......actual temperature (resp. differential

amount) the output voltage amounts 0V.

P33......integral part (I-part) of the output signal in 5

steps from appr. 0,25 to 4 minutes or oFF.

Analog Output Modes

P34 fixes the Analog Output Mode.

P34 = oFFOutput is de-activated.

P34 = 1 Output works proportional, that means

rising temperature

-> rising output voltage.

P31/P32 are absolute values.

P34 = 2 Output works anti-proportional, that

means rising temperature

-> falling output voltage.

P31/P32 are absolute values.

P34 = 3 Like P34=1 but the values set by

P31/P32 work relative to the current

setpoint 1 (P04 + offset).

Example:

P31 = 10°C, P32 = -10°C, P34 = 3,

P04 = 15°C, no current shift

Output Voltages:

10V at P04 + P31 = 25°C

0V at P04 - P32 = 5°C

P34 = 4 Like P34=2, but the values set by P31/

P32 work relative to the

current setpoint 1 (P04 + offset).

Example:

P31 = 10°C, P32 = -10°C, P34 = 4,

P04 = 15°C, no current shift

Output Voltages:

0V at P04 + P31 = 25°C

10V at P04 - P32 = 5°C

Example: Actual value Image

You need a remote display or similar, which shows

-50°C with 0V DC input voltage and +50°C with 10V

DC input voltage:

P32 = "-50", P31 = "+10", P34 must be "1".

Example: Proportional Controller

You want to drive e.g. a motor valve with 0-10V

DC input depending on a temperature. This valve

should be half open at 15°C. If the temperature falls,

the valves should open, if the temperature passes

10°C it must be full open. If the temperature rises,

the valve should be closed, with 20°C and above it

should remain closed.

P32 ="10.0", P31 ="20.0", P34 ="2"

Slow-down time / I-part

P33 (slow-down time) fixes the effect of the I-part

to the control process in 5 steps. The I-part amount

of the controlling variable is identical with the P-part

and will be added. The full size of the I-part will effect

after P33 is run down.

Effects of the Slow-down time

When P34 = 1

Act.Val. = Setpoint: Output 5V ± I-Part

Act.Val. > Setpoint: Output shifts with I-part

to 10V

Act.Val. < Setpoint: Output shifts with I-part

to 0V

When P34=2

Act.Val. = Setpoint: Output 5V ± I-Part

Act.Val. > Setpoint: Output shifts with I-part

to 0V

Act.Val. < Setpoint: Output shifts with I-part

to 10V

When P34 = 3

P31/P32 define a proportional band around the

active setpoint. The output voltage is 10V at P04

+ P31 and 0V at P04-P32.

Act.Val. = Setpoint: Output 5V ± I-Part

Act.Val. > Setpoint: Output shifts with I-Part

to 10V

Act.Val. < Setpoint: Output shifts with I-Part

to 0V

When P34 = 4

P31/P32 define a proportional band around the

active setpoint. The output voltage is 0V at P04

+ P31 and 10V at P04-P32.

Act.Val. = Setpoint: Output 5V ± I-Part

Act.Val. > Setpoint: Output shifts with I-Part

to 0V

Act.Val. < Setpoint: Output shifts with I-Part

to 10V

After an excursive change of the actual value the P-

part is calculated from the max. output voltage and

the proportional band:

Ux = (10V / (|P36 - P37| [K])) * delta Theta [K]

Example: • 10V Uout at +10°C, 0V Uout at -10°C

• aimed setpoint 0°C = 5V Uout

• current actual value 0°C

Actual value increases by 2K ->

• Uout rises to 6V immediately

• Uaus rises farther, after P38 is run

down, 7V will be reached.

Important: use double-pole

switches only if all controllers are

supplied by the same transformer

Electrical Cabinet

Important: Never connect

the secondary coil of the

transformer to PE!

Danger of destruction!

Attention

Networking of TAR controllers

All controllers can be networked to a host (PC or

SMZ) via their built-in RS-485-interface.

• Because all units are connected parallel on the

datacable,eachunithasitsownnetworkaddress

(P39) to ensure a specific communication.

!! Never use address 64 !!

• The data transmission speed is fixed by P38, the

default value is 9600 Baud.

• Wiring must be made by standard data cable.

• Shieldings must be connected to the nearest

grounding terminal.

• The unshielded part of the data cable must be as

short as possible.

Ifnetworkedcontrollers(1700-2typesonly)aresup-

pliedbyonetransformeronlyandthesinglepositions

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 PC-software notifies a unit breakdown !

A better way is not to switch-off the supply voltage

but to disable the unit by Digital Input.

CONNECTION INFORMATION & SAFETY INSTRUCTIONS

The guarantee will lapse in case of damage caused by failure

to comply with these operating instructions! We shall not be

liable for any consequent loss! We do not accept liability for

personal injury or damage to property caused by inadequate

handling or non-observance of the safety instructions!

The guarantee will lapse in such cases.

This manual contains additional safety instructions in the

functional description. Please note them!

If you notice any damage, the product may not be connected

to mains voltage! Danger of Life!

A riskless operation is impossible if:

• The device has visible damages or doesn't work

• After a long-time storage under unfavourable conditions

• The device is strongly draggled or wet

• After inadequate shipping conditions

• Never use this product 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.

• The product may only be used for the applications

described on page 1.

• Electrical installation and putting into service must be

done from qualified personnel.

• During installation and wiring never work when the

electricity is not cut-off ! Danger of electric shock!

• Never operate unit without housing.

Danger of electric shock!

• All ‘PE’ terminals must be connected to ground.

Danger of electric shock! Additionally, the internal noise

filter will not work, faulty indicated values may occur.

• Please note the safety instructions and standards of your

place of installation!

• Before installation: Check the limits of the controller and

the application (see tech. data). Check amongst others:

- Make sure that all wiring has been made in accordance

with the wiring diagram in this manual.

- Supply voltage (is printed on the type label).

- Environmental limits for temperature/humidity.

- Maximum admitted current rate for the relays. Compare

it with the peak start-up currents of the controlled loads

(motors, heaters,etc.).

Outside these limits malfunction or damages may occur.

• Sensor/probe cables must be shielded. Don’t install them

in parallel to high-current cables. Shielding must be

connected to PE at the end close to the controller.

If not, inductive interferences may occur.

• Please note for elongation: The wire gauge is not critical,

but should have 0,5mm² as a minimum.

• Mounting the controller close to power relays is

unfavourable. Strong electro-magnetic interference,

malfunction may occur!

• Take care that the wiring of interface lines meets the

necessary requirements.

• All used temperature sensors must be identical. Never

use different types at the same time. This will not work.

• TF-type sensors are not designed for being immersed in

fluids permanently. In such a case, always use dip-fittings.

With extreme temperature variations, the sensor may be

damaged.

Cleaning

to clean the product.

Never use acids or acidic fluids! Risk of damage!

Installation / Start-up

Read Safety Instructions !

If the TAR unit is switched ON, the display shows

the actual value of sensor 1. At first you have to set

the basic parameters:

• Enter Access Code '70' at P41

• Operating mode (P19)

• Type of used sensor (P25)

• Enter Access Code '88' at P40

• Switching characteristic of the relays

(P10-P13)

• Task of control input DI1 (OK1) (P29)

• If the unit is networked:

Address in network (P39) and Baudrate (P38)

• Function of the Analogue Output (P31 - P34)

This was the basic configuration, now you can enter

the specific setpoints, times, etc.

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.

Display Adjust

To calibrate the two actual value displays, use para-

meters P23 resp. P24 to correct the value.
