Installation
Connect the sensor cable connector to the universal interface (fig. 3, item 4).
Lay the sensor cable on the floor inside the area to be monitored.
To do so, first stick the supplied retaining clips to the floor using the adhesive.
Then press the sensor cable into the clips.
Note:
The sensor cable has a section of approximately 2.5 m at the connection end where
no leaks are detected. The start of the sensor cable itself is indicated by a yellow
marker.
Connect the leak sensor to the CMC III PU or to the neighbouring elements in the CAN bus using
a CAN bus connection cable (fig. 3, items 2, 3).
Status change display:
– The two green and the two red CAN bus LEDs on the CAN bus connection of the leak sensor
will start to flash.
– The multi-LED of the processing unit flashes continually in the sequence green – orange – red.
– The multi-LED of the leak sensor flashes blue continuously.
Press the "C" key on the CMC III PU (an initial audio signal will sound) and keep it pressed for
approx. 3 seconds until a second audio signal is heard.
Status change display on the CAN bus LEDs:
– Continuous green LEDs: CAN bus status "OK".
– Continuous red LEDs: CAN bus status "faulty".
Status change display on the multi-LED of the processing unit.
– Continuous green light: All devices connected to the CAN bus have the status "OK".
