Notes
:
•
RS-485 is used for communication network as specified in
Appendix C
(Terminals
10, 11, 12) and to connect (in safe area) to PC/Laptop for configuration/diagnostics.
•
Alarm relay:
•
N.O. energized contact in wiring options 1, 4, 5.
•
N.O. and N.C. energized in options 2 and 3.
•
0-20mA is ‘Sink’ in option 1 and ‘Source’ in option 2 and 3.
•
0-20mA ‘Source’ in options 2 and 3 available with the HART protocol.
•
In Wiring Option 1, link Terminals 1 and 8 to change the mA output to ‘Source’.
•
The Fault output is N.C. energized SPST relay. The contacts are closed when the
Detector is in its normal operational condition in options 1, 2 and 4, and available as
N.O. energized in options 3 and 5.
•
The Auxiliary output is N.O. energized (SPST) relay. The Auxiliary Relay may act in
parallel with the ALARM relay to activate another external device or it may provide a
warning signal, depending on the function configuration.
