Configuring your Detector 27
• 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.
2.8 Configuring your Detector
You can reprogram the function setup using the RS-485 connection or using
the HART protocol as follows:
• Mini Laptop Kit (P/N 777820): The mini laptop, pre-loaded with the
Spectrex host software, enables you to re-configure settings or perform
diagnostics on all 40/40 series flame detectors.
Refer to manual TM777070 for programming instructions when using the
Mini Laptop Kit.
• USB RS485 Harness Kit (P/N 794079-5): The USB RS485 Harness Kit
with RS485/USB converter, used with the Spectrex host software,
enables you to connect to any available PC or laptop to re-configure
settings or perform diagnostics on all 40/40 series flame detectors.
Refer to manual TM777050 for programming instructions when using the
USB RS485 Harness Kit.
• HART Protocol: Refer to Manual TM 777030 for programming
instructions.
These functions enable you to set:
• Alarm Delay
• Address Setup
• Mode of Operation
• Heated Optics Operation
The factory Default settings listed for each function are:
• Alarm Delay – A
• Alarm Latch – No
• Auxiliary Relay – No
• Automatic BIT – Yes
• Alarm BIT – No
