7.2. Trouble Test.
Cover the Prism totally with a non-reflective material and confirm that the Detector indicates a Trouble
condition after approximately 10 seconds (the amber LED on the Detector will illuminate, and the Trouble
relay opening will indicate this). The Trouble condition will automatically reset after a period not greater
than 2 seconds when the obstruction is removed.
8. Connection and Configuration Settings.
8.1. Field Wiring.
The field-wiring interface is accessed through the back plate of the Detector Head (See Fig 4). The 2-pin
connector is the port for the Low Level Controller. The 8-pin connector is the interface to the field wiring
and is numbered left to right. Each unit is fitted with a ‘flying’ lead, with an 8-pin connector fitted (6 pins
used), for easy field wiring. See table below:
