7.1 FAULTS AND FAULT CODES
The system can generate one fault code at a time. If a second fault condition occurs, it will register after the reset
button has been pressed and the first fault has been resolved.
The Stop button LED will display a 250 mS ON pulse (button illuminated) followed by a 250 mS OFF pulse (button not
illuminated). Once the number of pulses flash for the current system error, the pulse sequence will repeat after a one
second pause.
Fault Code
Stop Button LED
Indicator
Description
Stop Fault
Illuminated, no
pulsing
Occurs when the Stop Button on the panel door is
pressed. Stops system operation, all lubrication outputs
and the HVPS will be disabled.
Arc Fault
Continuously pulsing
Occurs when too much current flows through the HVPS.

Arc Fault Troubleshooting
Nozzle 1 Pressure Low Fault
Pulses 2 times
Time delayed fault–
when a pressure or flow sensor
detects problems with fluid delivery to the nozzles.
Nozzle 1 Pressure High Fault
Pulses 4 times
Time delayed fault–
when a pressure or flow sensor
detects problems with fluid delivery to the nozzles.
Nozzle 2 Pressure Low Fault
Pulses 6 times
Time delayed fault–
when a pressure or flow sensor
detects problems with fluid delivery to the nozzles.
Nozzle 2 Pressure High Fault
Pulses 8 times
Time delayed fault–
when a pressure or flow sensor
detects problems with fluid delivery to the nozzles.
Low Air Pressure Fault
Pulses 10 times
Indicates an open air pressure switch.
—When the air supply pressure drops below the required
pressure, the switch will open and latch the spray control
panel into a fault.
Low Reservoir Fault
Pulses 12 times
Indicates that the reservoir fluid level has fallen to an
unsafe operating level.
—When the fluid level drops below the float sensor level,
the switch will open and the system will latch into a fault .
SECTION 7
FAULTS AND TROUBLESHOOTING
NOZZLE PRESSURE LOW FAULT
Low fluid pressure can indicate a faulty pump, a faulty pump solenoid, or a leak in the tubing connecting the pump to
the nozzle.
NOZZLE PRESSURE HIGH FAULT
High liquid pressure can indicate an obstruction in the fluid delivery system, such as debris in the nozzle spray tube.
