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.

Troubleshooting Steps
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 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.
Voltage Too Low
•
Verify that line voltage is within the range specified in Technical Specifications,
page 26.
•
Use the recommended cord in Power Supply Requirements listed in the Driver
Installation manual.
•
Cycle power and check status indicator (L) to see if the error is still active.
Voltage Too High
•
Verify that line voltage is within the range specified in Technical Specifications,
page 26.
•
Cycle power and check status indicator (L) to see if the error is still active.
NOTE: To clear an error code, cycle power by turning
the power switch (S) 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. When the driver is on and pressurized
but the pump has not moved any material, the driver will
enter Standby Mode.
Standby Mode will be exited when:
•
Material starts to dispense and causes the pump to
move, OR
•
The pressure control knob (N) is adjusted, OR
•
The power switch (S) is cycled OFF and ON
