AUTOMATIC DOORS FOR LIFTS
The door reopens when the skate is closing.
•
- Check the regulation of the skate, because probably the locking system of the skate is not
well adjusted and the door has a mechanical friction. Verify if the the obstruction LED lights.
• The door hits when it opens.
- Check that the skate unlocking is well fixed before the door starts to open.
In case the skate is not fully fixed you should check the skate adjustment because it is probably too
hard.
• The door hits when it arrives at the fully open position, the "open" LED is not activated and
the system gets out of order.
- Check the tension of the toothed belt, because probably is not correctly adjusted and it slips
on the pulley of the motor and consequently the encoder is sending a wrong information.
Adjust the belt tension and make the autoadjustment again.
• The system gets power but doesn't work and the led ON is off.
- Check if both external fuse are burned and change it for another Fermator fuse
(250 V, 4 A ceramic fast speed).
• The motor is moving intermittently.
- Check the wiring connections or if a phase of the motor is failing.
- Verify that the pulley of the encoder is well assembled.
• The "ON" LED is activated and the door doesn't obey to the signals.
- There has been an obstruction at opening and then the door enters into an "out of order
stage" during 15 seconds.
- In slave mode, there is a continuous obstruction and the lift controller has not changed the
close signal by the open signal in slave mode.
- There has been a short circuit in the output of the motor, and the system will be deactivated
during 3 seconds.
