5 Important Information
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 equipment is 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" 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 these instructions manual valid for Europe, you must observe
out of their geographical scope the valid and relevant regulations of the corresponding country.
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power supplying this device before
Working on this device.
Attention!
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.
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.
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.
A circuit-breaker or switch must be situated within easy reach of the unit and fused. Installation
excess current protection should be ≤ 10 A.
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.
Temperature sensor terminals
The pin connections of Sensors 1...6 (below) is 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 these plug-in terminals have gold-plated contacts.
Do not use these plugs for other terminals
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 Disposal
Disposal should be carried out properly and in an environmentally friendly manner in accordance with
legal provisions.
