There are two types of switch panels: 8-stream and 18-stream. The 8-stream switch panel
is the standard panel, and is used when the GC has only one heater/solenoid board
installed; if two heater/solenoid boards are installed, then the 18-stream switch panel is
used.
Figure 2-4: Stream valve switches
A valve has the following three operational modes:
AUTO
The valve turns on and off according to the
Timed Events
table (accessible through
Rosemount MON2020). To set a valve to AUTO mode, set its switch on the switch
panel to the Up position.
OFF
The valve turns off and remains off until the operational mode is changed. To set a
valve to OFF mode, set its switch on the switch panel to the center position (the
switch is neither flipped up nor down).
ON
The valve turns on and remains on until the operational mode is changed. To set a
valve to ON mode, set its switch on th switch panel to the down position.

The switch panels also contain the following status lights that allow you to monitor the
GC’s condition:
Working

Unack. Alarm
Turns yellow if there is an unacknowledged alarm.
Active Alarm
Turns red if there is an active alarm.
Flame

photometric
detector (FPD)
The 18-stream switch panel contains an FID or FPD status LED that can
indicate the following:
•
A green light means the flame has ignited.
•
A flashing yellow light means an attempt is being made to ignite
the flame.
