LED is off.

Requirement is 100-240 VDC @ 47-
63Hz.
2. Verify that the power supply is
connected to the 24V input on the back
of the controller and that the ON/OFF
switch on the controller is in the ON
position.
Unit powers up okay but will not
respond to prober signal.
3. Verify input cable is plugged into the
prober input on the Controller.
2. Verify input cable is plugged into inker
jack on prober.
3. Check continuity of cable. Replace
/repair if defective.
Unit powers up okay, responds to
prober input but the shuttle does not
move.
1. Check that shuttle toggle switches on
the front of the controller are in the
RUN position.
2. Check that the air hose "quick
disconnects" on the back of the
controller are correctly oriented and
connected.
3. Place top mode switch to DISABLE.
Press the RESET button. The shuttle
should cycle. If it does not, and all air
hose connections are correct, the
problem may be that the shuttle
mechanism is binding
