TROUBLESHOOTING
SYSTEM WILL NOT OPERATE CORRECTLY IN AUTOMATIC MODE
1. Make sure Remote Switch is ON when attempting to
control with Remote Operators Control and OFF
when trying to control with the front panel controls.
2. Select Manual Mode on the AE120 front panel.
Attempt to move linear actuator with the Manual
Push Buttons. If linear actuator does not move:
a. Make sure there is no physical obstruction
or restriction to guide roll movement.
b. Check linear actuator limit switches. Both
limit switches should be closed, unless
linear actuator is at its travel limit.
3. Move web back and forth through sensor sensing
zone and determine if the Error Indicator lights up
symmetrically left and right as the web moves. If is
does not, recalibrate the system for the specific
sensor involved.
