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. 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!
Connecting temperature sensors Pt 100
Temperature sensors must be connected to the plug-in terminals 1T1, 1T2, 1T3 etc.
To ensure proper operation this plug-in terminals have gold-plated contacts. Do not use these plugs for other
terminals.
The measuring-inputs 1T1 to 4T3 and RESET Y1, Y2 do not have an insulation to
USB-Terminal and to analog output OUT 1 / OUT 2.
The temperature-sensors need an appropriate insulation that complies with SELV
(Safety Extra Low Voltage).
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 an 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.
Attention!
The sensor-alarm-relay K7 signals an error in a sensor. The relays for the
alarms 1-4 do not switch with a disturbance in a sensor. When relay K7 is
programmed in closed-circuit current mode (= release at alarm = factory setting),
also an interruption of the supply voltage and an instrument failure are reported.
We recommend the evaluation of K7.
