Causes
Troubleshooting
Fixes
• Faulty louver actuator.
• Test in “Manual Mode” to see
if louver actuator moves. Go to
Menu > Operations >
Manual
Mode. In Manual Mode verify
that internal louver actuator
switches are working by
observing relay ABD-1 and ABD-2
cycle on/off when the louver is
open/closed respectively.
• If a spare louver actuator is
available, swap it to see if it
works.
• Replace louver actuator (check
other causes before buying a new
component).
• Temporary fix: Reset louver
actuator by unplugging louver
actuator and then plug it back in.
• Faulty wiring path from louver
actuator switches to ABD-1 or
ABD-2.
• Obstructed path of the louver
actuator.
• Remove actuator and manually
move the louver to feel if there is
any resistance or obstructions.
• Remove obstructions.
• Blown fuse (F1) or (F9) in Panel
3.
2015-16 machines: F1 or F11.
• Visually inspect the fuses.
• Replace fuse.
• Blown fuse (F8) in Panel 2.
• Visually inspect the fuse.
• Replace fuse.
• Faulty relay ABD-2.
• Swap with relay ABD-1 to see if
it works.
• Replace relay.
• PLC and touch screen not
version 3.1 or higher
(Version 2.3 or higher for 2015-

• Update to Version 3.1 or higher
on the PLC and Touch Screen
