gas train), the High Temperature switch (located on
the roof of the cabin) or the Air Flow switch (Intake
Pressure switch). Each of these items may be
checked by proving 110 volts from their respective
terminals at the top of the Main Control Panel. The
airflow switch (intake pressure switch) is powered
through the flame safety module, and has two
terminals.
The flame safety module will give an alarm state
(lighting the red burner light on the touch screen
display) for one of three reasons. One, there is no
spark in the burner to ignite the burner pilot. Two,
there is no fuel being delivered to the pilot to create a
flame. Three, the flame guard device is not sensing
that there is flame in the burner.
COMPRESSED AIR FOR SPRAY
APPLICATIONS WITHIN BOOTH:
A solenoid is provided to control compressed air in
the booth. It is located within the Main Control
Panel. 110v power is provided to the solenoid
through the PLC output “5” on the display. For the
PLC to output at “5”, the RA air over electric switch,
Door Air switch, and Exhaust Pressure switch must
be closed giving power to the PLC input “12”.
