Installing the Detector
FV-40 Series Flame Detector
087-0056 REV F
36
*Available with the HART protocol.
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. de-energized contact in wiring options 1 or 4 or 5.
N.O. and N.C. de-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 or 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.

Configuring your Detector
Failure to follow these instructions could result in an incorrect
configuring of the detector which could lead to serious injury or
death.
You can reprogram the function setup using the RS-485 connection or using
the HART protocol as follows:
USB RS485 Harness Kit
(P/N 8000453): The USB RS-485 Harness Kit
with RS485/USB converter, used with the Scott Safety host software,
enables you to connect to any available PC or laptop to re-configure
settings or perform diagnostics on all FV-40 series flame detectors.
Refer to manual 087-0058 for programming instructions when using the
USB RS485 Harness Kit.
HART Protocol
: Refer to Manual 087-0057 for programming
instructions.
These functions enable you to set:
Sensitivity
Alarm Delay
Address Setup
Mode of Operation
Heated Optics Operation
