Description
No motor motion was
detected when the
operator was attempting
to move the motor.
Configuration was not
found or was reset to
factory setting
End positions are not
set or stored
Possible Causes Diagnosis
Worn motor brushes Motor DC resistance
should be less than 3
ohms. If it is greater
than 3 ohms, the
brushes may fail to
maintain contact
with the commutator
internal to the motor.

Voltage may vary over
a wide range, from

about 40 volts DC.

Resolution

Replace motor brushes
(extended duty models
only)
If voltage is absent during
activation, check for other
fault codes and correct as
necessary. If no other fault
codes are present, power
cycle the operator and try
again.
If fault persists, reset
settings to factory defaults
and reconfigure the
operators.
If fault still persists,
replace main board.
Correct any issues found
with encoder wiring
If encoder position does
not change with door
movement, the encoder,
encoder wiring, and
powerhead main board are
suspect. Check all three
for any visible damage.
Attempt power cycling and
restoring factory defaults.
Replace or repair
suspected faulty
components.
Review other fault codes
and perform problem
resolution as necessary.
Configure the operator per
the normal process.
