Troubleshooting
Control Board Status Light
D20
1.Plug sprayer into correct voltage, grounded outlet.
2.Set power switch OFF for 30 seconds and then ON again (this ensures sprayer is in normal run mode).
3.Turn pressure control knob clockwise 1/2 turn.
4.View digital displayy.
Keep clear of electrical and moving parts during trou- bleshooting procedures. To avoid electrical shock haz- ards when covers are removed for troubleshooting, wait 5 minutes after unplugging power cord for stored elec- tricity to dissipate.
For units without a display, see ProGuard (page 18). If there is a voltage supply issue (CODE 04, 08, or 17), the ProGuard status light will blink continuously when the ON/OFF switch is ON. To determine which code (or any other code besides voltage supply) refer to the control board status light. Turn the ON/OFF switch OFF, remove the control cover then turn power back ON. Observe the status light. Blinking LED total count equals the error code (for example: two blinks equals CODE 02).
