5.2 Installation
Leave the sensor cable on the transport coil until you are ready to lay it.

To lay the sensor cable, carefully wind the transport coil so that the cable is unrolled without twisting,
and positioned directly at the installation location.
Note:
The sensor cable must not be twisted or kinked while unrolling, and must not be trodden
on after laying. Otherwise, a short-circuit may occur, leading to a defect in the sensor ca-
ble.

Connect the sensor cable connector to the universal interface (fig. 6, 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. 6, 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".
