E-20: PURGE INITIATE ALARM
Cause Solution
System detects atomizing air to the gun when purge is
selected.
Shut off gun air.
For systems with a gun flush box, gun is not in the box
when purge is selected.
Place gun in gun flush box. Verify that gun flush box is
operating properly.
For systems with auto dump on, gun is not in the box
when auto dump is initiated.
Place gun in gun flush box. Verify that gun flush box is
operating properly.
For systems with a gun flush box, Fuse F2 is blown. Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
E-21: MATERIAL FILL ALARM
Cause Solution
For systems with minimum mixed material fill volume
entered, the system detects that fill volume is not
achieved during mixed material fill time.
Check for restrictions or leaks in the fluid supply system.
Check if the fill volume is properly configured:
• Adjust fill volume.
• Adjust fill time.
For systems without color change and with minimum
mixed material fill volume entered, Fuse F1 is blown.
Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
E-22: TANK A LOW ALARM, E-23: TANK B LOW ALARM, or E-24: TANK S LOW ALARM
Cause Solution
The tank volume reaches the low-level threshold. The EasyKey screen will display the alarm and prompt
the user to do one of the following:
• Refill tank volume to clear the alarm.
• Resume mixing by selecting “Spray 25% of remain-
ing volume.” If this selection is chosen, a second
alarm will occur after 25% of the remaining volume is
mixed. Refill tank volume to clear the alarm.
