1.1 General non-discrimination
In this operating manual, only the male gender is used where grammar
allows gender allocation. The purpose of this is to make the text easy to
read. Men and women are always referred to equally. We would like to
ask female readers for understanding of this text simplification.
1.2 Explanation of the signal words
Different signal words in combination with warning signs are used in this
operating manual. Signal words illustrate the gravity of possible injuries if
the risk is ignored:

7.3.2 24 V and 230 V alarm signals
The alarm input signal, e.g. from a gas warning device, is usually a 230 V
AC signal. Alternatively, you can also use a 24 V DC alarm input signal.
The control unit has been prepared for a 230 V AC alarm input signal on
the factory side. You can recognise this by the fact that a bridge is insert-
ed between terminals 2 and 3 on terminal block -X5. For a 24 V DC alarm
input signal, you must insert the red bridge between terminals 1 and 2.
Abb. 4: Brücken an -X4 (links) und -X5 (rechts)
Fig. 4: Bridges on -X4 and -X5
If the 24 V DC alarm input signal comes from a gas warning device or ex-
ternal control, the control unit itself must be potential-free (passive). To
this end, the bridge between terminals 6 and 7 on terminal block -X4
must be removed. The signal input contact is connected to terminal 5.
The external GND signal is connected to terminal 6.
If the 24 V DC alarm input signal is to come from a sensor, Emergen-
cy-Stop button, etc., the control unit must supply the 24 V DC supply volt-
age. For this purpose, the bridge is placed between terminals 6 and 7 on
terminal block -X4. The signal input contact of the sensor is connected to
terminal 5. The signal output contact is connected to terminal 6.
Terminal block -X4 also has a potential-free alarm output. Here, you can
connect e.g. a flashing light or alarm horn that signals the closing of the
ChlorStop valves.
7.3.3 Switching function of the control unit
To detect a cable break between the gas warning device and the control
unit, the switching function of the control unit is a normally closed con-
tact. This means that if the input signal is cancelled, the self-holding
function of the control unit is triggered and the voltage supply is interrupt-
ed. As a result, all connected ChlorStop valves close. If the control unit has
an uninterrupted voltage supply, the closing process is delayed.
If a normally open contact is required as the switching function of the
control unit, the contact on the respective relay must be connected from
14 to 12. However, this means that cable break detection is no longer
possible.
