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.

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 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.

The temperature of the system is near the maximum operation temperature. The
performance has been reduced to prevent the driver from completely shutting
down.
• Check fan operation. Clean the fan and driver housing.
• Reduce pressure, duty cycle, or gun tip size.
• Move the unit to a cooler location.
