Error Code Troubleshooting
Error codes can take two forms:
•
Alarm: Alerts you to the cause of the alarm and
shuts down the driver.
•
Deviation: Alerts you to the problem, but the driver
may continue to run past the set limits until the
system absolute limits are reached.
NOTE:
The blink code is displayed using the status
indicator (L) on the driver. The blink code given below
indicates the sequence. For example, blink code 2
indicates two blinks, a pause, and then repeats.
NOTE:
To clear an error code, first try turning the
pressure adjustment knob (H) counterclockwise until it
stops. If the status indicator (L) does not stop blinking
shortly after turning the knob to zero, cycle the power by
turning the power switch (E) to the OFF position for at
least 30 seconds before turning back ON.
Standby Mode
When slow blinking is displayed, the driver has entered
Standby Mode. The driver will enter standby mode when
powered on and pressurized with a knob setting greater
than 7, and the pump has not moved any material for 30
minutes.
Standby Mode will be exited when:
•
Material starts to dispense and causes the pump to
move, OR
•
The pressure control knob (H) is adjusted, OR
•
The power switch (E) is cycled OFF and ON

Troubleshooting Steps
1
Alarm
Pump Diving
The pump is diving rapidly. A pressure imbalance between the up and down stroke
of the pump is causing the pump to dive with excessive speed.
•
Pump diving may occur when the pump runs out of material while spraying at
high pressure.
•
Verify that material is being properly fed to the pump.
•
Pressure from the hose could flow back into the pump on the down stroke.
•
Verify that the check valve is installed and is properly working.
2
Alarm
Voltage Too Low
•
Verify that line voltage is within the range specified in
, page 27.
•
Use the recommended cord in your driver manual.
•
Cycle power and check status indicator (L) to see if the error is still active.
3
Alarm
Voltage Too High
•
Verify that line voltage is within the range specified in
, page 27.
•
Cycle power and check status indicator (L) to see if the error is still active.
4
Deviation
High Temperature
The temperature of the system is near the maximum operation temperature. The
performance has been reduced to prevent the driver from completely shutting
down.
•
Reduce pressure.
•
Move the unit to a cooler location.
