Mounting and Installation
Applying AC supply voltage at devices
with bridge rectifier circuit :
A bridge rectifier circuit is used for rectifying AC supply voltage.
Applying DC supply voltage at devices
with bridge rectifier circuit :
This device variant can be supplied with 15 ... 36 V DC.
Because of using bridge rectifying, polarity of supply voltage
is not relevant.
G
Switching status selectable via DIP switches
Self-locking:
By means of DIP 1 self-locking at the occurrence of moisture
can be activated. A RESET can be done by pressing a pushbutton or
by voltage OFF ⁄ ON.
Relay status:
By means of DIP 2 the relay status for setting off alarm
can be inverted so that the relay either drops when ELECTRODES
are conductive or when conduction is interrupted.
