Error codes can take two forms:
• Alarm: Alarm: Alerts you to the cause of the alarm and Alarm:
shuts down the driver.
• Deviation: Deviation: Alerts you to the problem, but the driver Deviation:
may continue to run past the set limits until the
system absolute limits are reached.
NOTE: The blink code is displayed using the status
NOTE: NOTE:
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: NOTE: To clear an error code, first try turning the NOTE:
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.

Pump Pump diving Pump diving 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.

High High Temperature High Temperature 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.

Standby Mode

Standby Standby Mode 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
