Error Code Troubleshooting
To troubleshoot using an error code, you need to first
determine your blink code.
1. The blink code is displayed using the status
indicator (L) on the motor. The blink code given
below indicates the sequence. For example, blink
code 2 indicates two blinks, a pause, and then
repeats.
2. Error codes can take two forms:
• Alarm: Alerts you to the cause of the alarm and
shuts down the motor.
• Deviation: Alerts you to the problem, but the motor
may continue to run until the absolute limits are
reached.
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 motor has entered
Standby Mode. The motor will enter Standby Mode
when powered on and pressurized with a knob setting
greater than 7, and the pump has not moved any
disinfectant for 30 minutes.
Standby Mode will be exited when:
• Disinfectant 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

Blink Code Error Type Troubleshooting Steps
1 Alarm
Pump Diving
Pump diving is when the pump moves through the down stroke too rapidly. A
pressure imbalance between the up and down stroke of the pump cause the pump
to dive with excessive speed.
•
Pump diving may occur when the pump runs out of disinfectant while spraying
at high pressure.
• Verify that disinfectant 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.
• Cycle power and check status indicator (L) to see if the error is still active.
2 Alarm
Voltage Too Low
• Verify that line voltage is within the range specified in
Technical
Specifications
, page 37.
• 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
Technical
Specifications
, page 37.
• Cycle power and check status indicator (L) to see if the error is still active.
