Notes: 1. Where the sensor is earthed locally, either to the stud or through
the sensor casing or mounting, to avoid earth loops the screen
sheath should only be connected at one end, i.e. the sensor
or at the relay/interface card.
2. The above diagram shows the sensor connections for
Channel 1. Channels 2, 3 and 4 connections are similar and
their pin connection numbers are shown below:
