5 Important Notes
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
To use the equipment flawless and safe, transport and store properly, install and start professionally and
operate as directed.
Only let persons work with the equipment who are familiar with installation, start and use and who have
appropriate qualification corresponding to their function. They must observe the contents of the instructions
manual, the information which are written on the equipment and the relevant security instructions for the
setting up and the use of electrical units.
The equipments are built according to DIN / EN and checked and leave the plant according to security in
perfect condition. To keep this condition, observe the security instructions with the headline „Attention“ written
in the instructions manual. Ignoring of the security instructions may lead to death, physical injury or damage of
the equipment itself and of other apparatus and equipment.
If, in any case the information in the instructions manual is not sufficient, please contact our company or the
responsible representative.
Instead of the industrial norms and regulations written in this instructions manual valid for Europe, you must
observe out of their geographical scope the valid and relevant regulations of the corresponding country.

ATTENTION!
When all relays are programmed in operation current mode (= pick up at alarm), a
loss of the supply voltage or an instrument failure can remain unidentified. When the
relay is applied as control instrument, the operator must ensure, that this error is
recognized by regular examinations. We recommend to program and accordingly
evaluate at least one relay in the closed-circuit current mode.
Caution! Temperature sensor terminals
The pin connections of Sensors 1…6 (below) are not compatible with Sensors 7…12 (above). If a 3-wire-
technique sensor connected below is to be connected above, both external connections must be swapped.
Temperature sensors must be connected to the plug-in terminals T11, T12, T13 etc. To ensure proper
operation this plug-in terminals have gold-plated contacts. Do not use these plugs for other terminals.
Caution!
The sensor inputs and the RS485 interface are applied to the same electrical potential but are galvanically
isolated (2kV) for the auxiliary voltage. Take this into consideration during configuration.
RS485 connection:
Use RS485 Interface only with shielded wires.
Large cable lengths may shift the potential ground and the transmission can be disturbed.
Corrective measures can be galvanic separation or an additional ground wire.
Max. allowed cable length is 1000m.
6 Installation
The device can be mounted:
Distribution board or switchgear cabinet on 35 mm rails according to EN 60715
Observe the maximum temperature permissible when installing in switching cabinet. Make sure
sufficient space to other equipment or heat sources. If the cooling becomes more difficult e.g.
through close proximity of apparatus with elevated surface temperature or hindrance of the cooling
air, the tolerable environmental temperature is diminishing.
Attention! Universal power supply
The unit is equipped with a universal power supply that is suitable for DC- and AC-
voltages. Before connecting the unit to the current, make sure that the allowed scope
of voltage of the control voltage Us, written on the lateral type plate, corresponds to
the supply voltage of the unit.
A circuit-breaker or switch must be situated within easy reach of the
unit and fused. Installation excess current protection should be ≤ 10 A.

8.5 Configuration mode (last decimal point flashes)
The value of a parameter can be set in the configuration mode. The display continually alternates between
the parameter name and the currently set value until the Up/Down key is pressed, which changes the value of
the parameter. If no key is pressed for 2s, the display starts alternating.
If no key is pressed for 30s (simulation mode 15min), one automatically returns to the display mode (the most
recently set value is taken over)
Function key
Set / Reset
Press briefly: The settings are taken over; continue to
next parameter. After the last
parameter, change into menu mode
Press for ≥2 s: Returns to display mode (except
simulation mode), the most recently set
values are taken over during this
Function key
Up / Down
Press short/long: Changes the parameter value
(fast/slow)
Hint: Pressing the Up and Down keys simultaneously sets the adjustable value to zero. If you keep the Up or
Down key pressed while setting a value, the speed of the change in the display is accelerated.
8.6 2-wire technique line resistance compensation
Connect the sensor at terminals xT1 and xT3, xT2 has to be open.
To compensate the line resistance short-circuit the wires nearby the sensor and measure the line resistance.
We recommend using 2 or bettering 3 wires for each sensor. With 2-wire connection and a common line for
all signals, all sensor measuring currents will be added on the common line. Thus the value of the
compensation line resistance RK must be calculated as follows: RK = (n+1) x RL/2 (RL = line resistance of
two wires, n = number of sensors)
