1. Before Startup
When operating the alarm unit, certain parts of the
module can carry dangerous voltage! Ignoring the
warnings can lead to serious injury and/or cause
damage!
The alarm unit should only be installed and put into
operation by qualified staff. The staff must have
studied the warnings in these operating instructions
thoroughly.
The adjustment with the potentiometer on the front
may only be carried out with a screwdriver which is
securely insulated against the input voltage! Do not
select ranges during operation.
In applications with high operating voltages
sufficient distance and isolation as well as shock
protection must be ensured.
Safe and trouble-free operation of this device can
only be guaranteed if transport, storage and
installation are carried out correctly and operation
an maintenance are carried out with care.
Appropriate safety measures against electrostatic
discharge (ESD) should be taken during range
selection and assembly on the alarm unit.
2. Short description
The Alarm Unit is used to monitor limit values and control
automation processes in 0(4) ...
±20 mA and 0 ... ±10 V standard
signal circuits. Two switch channels with one SPDT relay each can
be separately configured by using DIP switch. The switch point and
hysteresis can each be adjusted by means of their own 12-turn
potentiometer located on the unit’s front. Input, power supply and
the relay outputs are protective separated.
3. Functioning
The signal on input will be compared with the adjusted limit value.
Depending on setting the output relays react. The switch state is
indicated by a yellow LED. Both switch outputs can be set up as
either MIN or MAX alarm. Additionally the SPDT relays can be
configured as Normally Open (
de-engergized) or Normally Closed
(energized), so it is possible to consider the switch state by power
off. The power-detect function (S1-8) set Relay
II under proper
power conditions independent of the input signal. A green LED on
front indicate the auxiliary power.
4. Configuration
Set the DIP switch as indicated in the following table:
S1- OFF ON
1 Relay I MAX Relay I MIN
2 Relay I N.O. (Normally Open) Relay I N.C. (Normally Closed)
3 Relay II MAX Relay II MIN
4 Relay II N.O. (Normally Open) Relay II N.C. (Normally Closed)
5 Relay. II normal function Relay. II power detect
6 Input 0 ... 20mA/10V Input ± 20mA / ±10V
7 - -
8 - -
Boldface: Factory setting
After configuration switch point and hysteresis will be adjusted with
the potentiometers on the front. Connect a current/voltage source
with desired limit values on input terminals and adjust the set point
by observe the LED. Note that the LED indicates the state of the
comparator, not the state of the relay because it could be inverted
as result of the N.O./N.C setting!

2) As far as relevant the standards and rules mentioned above are considered
by development and production of our devices. In addition relevant assembly
rules are to be considered by installation of our devices in other equipments.
For applications with high working voltages, take measures to prevent
accidental contact and make sure that there is sufficient distance or insulation
between adjacent situated devices.
