Note: 1. Where a sensor is earthed locally, either to the Earth Stud or
through the sensor casing or mounting, to avoid earth loops
the screen sheath of the cable should only be connected at
one end. ie. At the sensor or at the Interface/relay Card.
2. The Searchline Excel analogue output is non isolated and is
factory configured as current sink or current source.
