Operating Instructions
RDW 03 Monitoring Electronics
M
The system quickly and reliably detects even small
liquid leakages. It transmits a warning in form of an
acoustic and optical alarm signal. At the same time,
floating contacts take care of the transfer of corre-
sponding messages to the building management
and control system.
The system is equipped with
• Electronic monitoring system
• Point sensor/sensor cable
• Accessories
Applications
Computer centers, ultraclean rooms, libraries,
banks, insurance companies, public buildings
The contact overviews shown for the “break” and “alarm” relays under terminal assignment in the
documentation for the connected RDW 03 are depicted with the following status:
RDW 03 to voltage – sensor connected – operating status ready = no leakage present
“Break” relay is energised, i.e. electrical contact between terminals 4 - 5;
“Alarm” relays are de-energised, i.e. electrical contact between terminals 6 - 7, 9 – 10
When the RDW 03 is disconnected from the power supply,
the “Break” relay is de-energised = fail safe for system safety.
If a leak is detected, the “Alarm” relays are energised;
recommendation: use terminals 6 - 7, 9 - 10 = fail safe for detecting a leak.
