POSSIBLE RESOLUTION
Safety sensors are not installed, connected or wires may be cut. Inspect
sensor wires for a disconnected or cut wire.
There is a short or reversed wire for the safety sensors. Inspect safety sensor
wire at all staple points and connection points and replace wire or correct as
needed.
The wires for the door control are shorted or the door control is faulty. Inspect
safety sensor wire at all staple points and connection points and replace wire
or correct as needed.
Safety sensors are misaligned or were momentarily obstructed. Realign both
sensors to ensure both LEDs are steady and not flickering. Make sure nothing
is hanging or mounted on the door that would interrupt the sensors path while
closing.
No RPM pulses have been detected. Check the door manually for balance,
binding or obstructions. Internally the possible cause may be the motor, logic
board or RPM sensor. Try resetting door travel limits. Contact service centre.
RPM pulses have been detected after motor has turned off. Possible broken
spring. Check the door is correctly balanced and not creeping up or down.
Contact a door service centre.
Possible logic board failure. Reboot opener by turning the mains power OFF
and then ON after 15 seconds. Reprogram the door travel limits and force
settings. Contact service centre.
Check the passpoint module has been activated by the belt Position Tab,
during the door travel. Reset the travel limits.
Check travel module for proper assembly, replace if necessary.
Battery backup charging circuit error, replace logic board. *(if applicable)
Manually open and close the door. Check for binding or obstructions, such as
a broken spring or door lock. If the door is binding or sticking contact a trained
door systems technician. If door is not binding or sticking attempt to reprogram
travel (refer to page 24 ).
Communication error to travel module. Check travel module connections,
replace module if necessary.
