INSTALLATION CHECKLIST
The following checklist is provided as a means of
double checking the system to be sure that all phases
of system installation are complete and have been
performed correctly.
1. OPECL detector is installed as described in the
OPECL manual (95-8556).
IMPORTANT
To ensure proper operation, the OPECL must
be configured for PIR9400 Analog Fault Code.
Refer to the HART section in the OPECL manual
(95-8556) for more information.
2. OPECL housing covers are tightly installed.
3. All cable shields are properly grounded.
4. Conduit seals have been installed at all junction box
entries (if conduit is being used).
5. OPECL to controller wiring is correct.
6. Power wiring to OPECL and the controller is installed
and power source is operational.
7. External loads are properly connected to the
controller.
8. Controller is programmed as desired. Record this
information for future reference.
9. Controller is properly installed in the mounting
enclosure.
10. Proper ventilation is provided to prevent over-
heating of the controller.
Proceed to Startup Procedure, Setpoint Adjustment,
and Calibration.
STARTUP PROCEDURE
1. Output loads that are normally actuated by the
gas detection system should be secured (remove
power from all output devices) to prevent undesired
activation.
2. Check all external wiring for proper connection.
3. Before installing the controller in the mounting rack,
inspect it to verify that it has not been physically
damaged in shipment. Check the jumper plugs
and rocker switches on the controller for proper
programming, then slide the controller fully into the
mounting enclosure.
4. Apply power to the system.
NOTE
The controller has a power-up delay before
beginning normal operation after power is applied
to the system. During this time the outputs are
inhibited, the FAULT LED is illuminated, and
the current output indicates a fault condition.
This delay allows time for the OPECL output to
stabilize before beginning normal operation.
5. Put the controller in the Setpoint Display mode to
determine the present alarm setpoints. If changes
are required, perform the Setpoint Adjustment
procedure.
6. Perform the calibration procedure. This involves
zero calibrating the OPECL using the procedure
described in the OPECL manual, then calibrating
the controller using the procedure described in the
“Calibration” section of this manual.
7. Check the 4 to 20 mA current loop for proper
calibration and adjust as required.
8. After calibration is completed, restore the system
output loads to ready condition.
