New software was installed during routine maintenance.
or
Non-volatile memory contains invalid data or has malfunctioned.
Reset all parameters to their default values:
Caution:
This procedure will erase all previously entered parameter
settings! Be sure to record all current settings on page 39 before
performing this step. If you are installing new software, then you must
record the current settings
before
installing the new microcontroller
chip.
1. Turn the AC power
off
.
2. Press and hold the EXIT button.

4. When the ‘reset’ message appears on the numeric display, release the
EXIT button.
5. Set parameter 2 (end-of-travel mode) and other parameters to their
previous values. Refer to page 17 for more information about setting
controller parameters.
Sensor polarity is wrong.
The value of parameter 3, 4, or 50 must be
changed for the selected sensor. Refer to page
6
17 for more information
about setting controller parameters.
Servo gain is too high.
Decrease the value of parameter 5. Refer to page

End play in the actuator or mounting.
Press the MANUAL button and
then press IN and OUT buttons several times. Actuator operation should be
smooth and free, without binding. Firmly grasp the web guide mechanism
moving part and push and pull to check for end play. Observe the actuator,
mechanical components, and mounting hardware. There should be no
observable motion in the mechanical system. If motion is noted, repair the
web guide or actuator as required, or return the equipment for repair.

Sensor in wrong position.
Unwind stand:
The sensor should be located down-web, close to the last
shifting idler roll. Refer to the guide application drawings on page 137.
Winder stand:
The sensor should be located up-web before the last fixed
idler roll, one to two web widths from the shifting base. Refer to the guide
application drawings on page 137.
Intermediate guides:
The sensor should be placed close to the exiting
idler roll. Refer to the guide application drawings on page 137.
Excessive chuck wobble.
Decrease the web speed or re-chuck the roll of
material.
