corresponding field wires in a twin ferrule and crimp it.
When shielded cables are used:
A Strip shield by 45 mm.
B Twist the shield and connect a ferrule.
C Connect the shield to pin 1 of the sensor connector
(24)

2. Wait until the warm-up phase ends.
Depending on the installed sensor the warm-up phase can
take between 5 minutes and 12 hours. Settings can
already be made in the menu.
3. Calibrate sensor
4. Perform test:
a. Check transmission of signal to the control unit.
b. Check triggering of integrated alarm devices.
c. The optionally connected external relays
