10. TROUBLESHOOTING GUIDE
Operator is checking continually the proper performance and runing a continuous diagnosis of key components of the
machine and monitorize all sensors connected to the control board. So that, if any failure is detected digital selector
warns the error type.
This is the list of errors operator can detect automatically:
LIST OF ERRORS
Type of
Error
Description
Possible cause
Possible solution
Error 1
Incomplete Set up
“Set up” maneuver it has not
been performed
Activate “set up” from
digital or key selector
Error 2
Obstruction
Door might be bloqued by an
obstacle.
Check if door has any
obstacle. Check motor
turns free or check encoder
cable.
Error 3
Electrolock failure
Electrolock might be stuck
If it is a “failsafe” lock set
test in OFF and leave
operator working. Then
remove it. If it is
“failsecure” remove it.
Error 4
Microprocessor memory failure
Damaged microprocessor
Remove control board
Error 5
Motor driver temperature
The transistor of motor
control are overheated or
damaged
Door will open slowly and
stop until driver
temperature is cool.
Error 6
Motor overcurrent
Motor brushes damaged
Remove motor
Error 7
Motor temperature
Motor is overheated
Door will open slowly and
stop until motor
temperature is cool.
Error 8
Inside photocell continuously
activated
Obstacle in the detection area
of photocell
Remove obstacle
Error 9
Outside photocell continuously
activated
Obstacle in the detection area
of photocell
Remove obstacle
Error 10
