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

Operating

Operating Elements

Parameters (setpoints, times, etc.)
All selectable parameters hold a parameter number (e.g. P03), you

will find a listing on the next page.

Calling up and editing

Press key 'P'............. parameter number appears

Use 'ñ/ò' .................select desired parameter

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

Use keys 'ñ/ò' .........adjust parameter value

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

Auto scrolling
Hold 'ñ/ò'-keys to scroll values automatically.

Manual Defrost
In cold storage controller mode (P14=4) and while the actual control

value is displayed, a defrost event can be initiated by holding the 'ñ'-
key for more than 2,5 seconds.
The defrost event can be terminated holding the 'ò'-key for more
than 2,5 seconds.

Detecting controller type without a type label

1. Switch off supply voltage

2. Push and hold key 'P'

3. Switch on power again.
Now the display shows one after another :

manufacturing.

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.
