Functional Testing
Module 9095
7-6
Your detector continuously monitors the presence of this important signal via a
circuit called OScillator GOing.
The AC signal is converted to a DC signal that can be found on pin 11 “yellow
wire” on PL1. If this voltage falls below 1V then a “System fault” is generated,
that causes the “Fault Relay” to operate and in turn the “Reject Device” so that
no product will pass undetected.
In the unlikely event of an OSGO generated System fault, transmitter failure
confirmation can be made by using the DMM set on the 20V DC range or
equivalent to measure the voltage at PL1 with respect to the adjacent control
on page 20
in the “Maintenance” section of
this manual shows the connections for PL5. If a failure is confirmed then please
call your local Group Service Centre.
