Connection of the Sensor

Read the chapter on Safety and, in particular, the section on Installation and
Commissioning (see chapter 1.6) before connecting the sensor.
Warning!
Risk of short circuit
Injuries and damage to the device are possible when working with live parts.
Before working on the device, always disconnect the supply voltage.
■
Connect the device to the supply voltage only after completion of the work.
■
Take care not to reverse the polarity when connecting the sensor cable. The loop
resistance of the extension cable should not exceed 20 Ω for the sensors.
For extending the sensor cable, use cable connector LAL-SK2.
Note!
Avoid installing sensor cables parallel to other cables that may transmit interfering
signals, which impair the sensor signal and thus the alarm function. Use
unshielded 2-wire cable for each sensor.
To ensure perfect operation of the warning device, do not exceed:
the max. cable length of 190 m with a cross-section of 0.75 mm
■
the max. cable length of 250 m with a cross-section of 1 mm
■
Note!
Further information on connection of the sensors to the warning device is
available in the manual of the warning device NVD-111.
