Error Codes - Graco e-Xtreme Z25 Operation - Repair - Parts

Error Codes

Error codes can take two forms:
Alarm: alerts you to the alarm cause and shuts down
the pump.
Deviation: alerts you to the problem, but pump may
continue to run past the set limits until the system's
absolute limits are reached.
NOTE: The blink code is displayed using the power
indicator (L) on the driver. The blink code given below
indicates the sequence. For example, blink code 2
indicates two blinks, a pause, then two more blinks, and
then repeats.

Voltage Too Low
• Verify that line voltage is within the range specified in Technical Data,
page 25.
• Use the recommended cord (see page 6).
• Cycle power and check status indicator to see if error is still active.
Voltage Too High
• Verify that line voltage is within the range specified in Technical Data,
page 26.
• Cycle power and check status indicator to see if error is still active.
• Verify that outlet check valve is installed on pump and functions properly.
NOTE: A faulty outlet check valve can result in excessive pump speed and
cause high voltage internally to the electric driver.
Low Temperature
• Warm equipment.
• Contact your Graco distributor or Tech Service for more information.
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 OFF.
Power Saving Mode
When fast blinking is displayed, the sprayer has entered
Power Saving Mode mode. When the sprayer is on and
pressurized but the pump has not moved any material in
30 minutes, the sprayer will enter Power Saving Mode
and will only control up to 75% of the maximum pressure.
Power Saving Mode will be exited when:
• Material starts to dispense and causes the pump to
move, OR
• The pressure knob is adjusted, OR
• Power is cycled OFF and ON
