CHAPTER 12: TROUBLESHOOTING
Notice: If after troubleshooting a problem, and a satisfactory solution cannot be achieved, please call
Nabco Entrances at 1-877-622-2694 between 8 am – 4:30pm Central time for additional assistance.
DO NOT leave any problem unresolved. If the door cannot be repaired immediately, turn off the
door and leave it inoperable until repairs can be made. Advise the owner NOT to operate the door
in the automatic mode until repairs are effected. NEVER leave a door operating without all safety
detection systems operational.
Programming Issues
Problem
Possible Solution
Control does not react to
Activation signal
►
At the main screen, confirm that “IN” or “EXT” highlights when an activation signal is applied. If
not, check the wiring or the activation device.
►
At the main screen, determine if “BA” is highlighted. If a 4-wire on/off/hold-open switch is
being used, with a blue wire connected to terminal 8, then “Input BA Circuit” (found under
“Input Settings”) must be set to “Normally Closed”. If a 3-wire switch is being used, or no
switch is being used (nothing connected to terminal 8), then “Input BA Circuit” should be set to
“Normally Open”.
►
At the main screen, if Status shows “Stopped” while the door is closed, and BA is not
highlighted, turn off power for at least 4 seconds then turn on again. With the door still closed,
status should now show “Fully Closed”.
►
Must navigate back to the main screen (as shown at right) for an activation signal to work.
Hard to manually open door
►
Software Revision (up to, and including 18)
• Re-enter “0” for “hold closed force” under “optional settings”. The software on early Opus
controls may suggest it’s already set to “0”, but does not act like it. Enter “0” again to fix it.
After manually opening door,
the door stays open
►
Software Revision (up to, and including 18)
“Manual Open Function” is set to “No Action” and “Manual Open Sensitivity” is set to “0”. If “No
Action” is desired, change “Manual Open Sensitivity” to anything other than “0”.
Closing functions do not
work when opened manually
►
Software Revision (up to 17)
• Closing functions such as (speed, latch-check, power close), change “manual open function”
to something other than “no action”. “stop and close” is usually ideal.

Check Motor Fuse.
►
Check Motor for open circuit, short circuit, or short to ground.

It is possible electrical noise may cause a false error. If the error does
not occur repeatedly then it’s most likely not
an issue

Encoder Error
►
Check all connections between the Control and Motor.

It is possible electrical noise may cause a false error. If the error does
not occur repeatedly then it’s most likely not
an issue.

This could be a random error.
• If the error occurs repeatedly, please replace the OPUS Control.
