CHAPTER 13: 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
Hard to manually open door
►
On outswing only: Check if shoe position and rod length are in accordance with dimensions
shown within the manual.
►
Except GT710: Reduce the preload on the operator. The Opus is not dependent on preload
since there is no cam and door position switches. Maximum preload on GT8500’s should be one
notch on the operator spline to maintain ANSI 156.19
►
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.
Door does not always close
during Latch Check
►
Software Revision (up to, and including 19)
►
Symptom: When the door is used manually it closes every time. However, when the door is
activated, once in a while it will stop at latch check and not continue to close.
• Increase latch check speed or try increasing operator arm preload (if GT710 - increase spring
tension on hydraulic closer)
Sim Pair behaves oddly
Controls may not be communicating correctly.
Please refer to
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.
Double Egress pairs are not
Synchronizing
►
Software Revision (up to, and including 20)
• Remove CANbus cable. Set both Controls as single doors. The activation signal should
be paralleled between both Controls. Safety signals should only be attached to their
corresponding door’s Control.
►
Software version is 21
• Be sure both controls are set to “Double Egress”. Safety signals should only be attached to
their corresponding door’s control.
• See also “Sim Pair behaves oddly” located at top of this Table.
Sim Pair using “Stop & Close”
but results in a “Push & Go”
►
Software Revision (up to, and including 20)
• Remove sim-pair harness, set both controls to “single door”, parallel the common terminal
and any input being used between both controls.
