5.2 Installation

Connect the sensor probe connector to the universal interface (fig. 6, item 4).

Lay the sensor to the measuring point.

Fit the sensor probe so that the contacts are pointing vertically downwards towards the floor.
Note:
In order to be able to detect leaks rapidly, the contacts of the sensor probe should be
fitted as close as possible to the floor, approximately 1 to 2 mm above it.

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".
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".
– Continuous orange light: At least one device connected to the CAN bus has the status "Warning".
– Continuous red light: At least one device connected to the CAN bus has the status "Alarm".
