2. Check the vacuum sensor adjustment. First, be aware that the vacuum sensor adjustment is a 270
°
total turn potentiometer.
If you try to turn it more than the 270
°
°°
°
allowed, it will break. The
vacuum generator is an expensive component and abuse is not covered by the E
XATRON
warranty.
The red indicator LED on the vacuum generator should normally be off. Turn on the vacuum using
the handler's yellow vacuum override button. The red indicator LED will remain off. Cover the
vacuum hole in the handler plunger/apply head with one device. (You may also cover the vacuum
hole with the end of your finger, although this may not be as accurate.) You will hear a noticeable
change in the sound of the vacuum as it intercepts the device (or your finger) and the red indicator
LED should turn on.
If the red LED does not turn on, adjust as needed by carefully turning the potentiometer clockwise
until the red LED comes on.
3. If the valves in the vacuum generator assembly become plugged with dirt, you may send the
assembly back to E
XATRON
Customer Service where it will be repaired, if possible, for a fee.
REMEMBER
: Damage caused by a dirty air supply is not
covered by the E
XATRON
warranty.
If you are experiencing dirt-clogged vacuum generator valves, check the air regulator. Verify that it is
clean and properly installed. Please refer to the Air Regulator Maintenance Guidelines section earlier
in this chapter, and as always, contact the E
XATRON
factory for assistance as needed.
