Troubleshooting Guide
Problem Likely Cause(s) Possible solution(s)
The door moves slowly, reaches
the endstop and then fails to stop
with a loud “clack clack clack”
noise.
• Door too light
• Endstops not secure
enough.
• Add weight to door as shown
on page 36.
• Make sure the endstops are
secure, if not you may need to
retrofit additional endstops.
SECTION B: GENERAL OPERATING MODE TROUBLESHOOTING
Problem Likely Cause(s) Possible solution(s)
Wall console constantly beeps
twice
• No mains present
• Mains fuse blown
• Check plug socket, and circuit
breaker.
• Replace the fuse (1A Time lag
glass cartridge). It is an inline
fuse fitted on the mains lead.
Wall console constantly beeps
four times
• MAIN FUSE (F2) in wall
console blown.
• Interconnection lead
problem.
• Check the fuse (F2) in the wall
console and replace if blown or
faulty.
If the fuse repeatedly
blows, please contact
technical support.
• Check the interconnection
lead, make sure it is plugged
in securely at both ends.
The lead can be checked by
measuring the outer terminals
for voltage (between 23 and
30 volts DC, depending on
mains voltage)
Door opens a short distance, then
stops. Cannot open door greater
than this distance.
• Encoder problem
• Disengage the door, and open
and close fully, and ensure that
the gear turns all the time
when the door is closed and
opened fully. If it does not, the
spool wheel has likely
damaged the drive wheel and
pulled it off the chassis. This
occurs due to incorrect
installation!
• Encoder dirty, ensure it is
clean and free of debris.
Sometimes insects and other
objects get into the encoder.
