2.3.2.3 Relay Contacts

There are two sets of relay contacts available via the output connector:
Process Alarm (Relay 1)
This relay changes state to indicate that the process variable has exceeded the alarm
set point value. See section 3.2 for details on how to configure the process alarm trip
criteria. This alarm can also be used to give an early indication that the optics require
cleaning.
System Alarm (Relay 2)
This relay changes state to indicate a fault has occurred which requires operator
intervention. See section 4.6 for detailed information on faults.
