AUTOMATIC DOORS FOR LIFTS

•
The control does not answer to the TEST or AUTOADJUSTMENT button.
- Switch off and on the controller and test again. Change the controller If nothing happens.
•
The door does not move.
- Verify the motor cable and its connection with the motor connector.
- Verify that a variable voltage is applied to the motor when a movement order is applied. This voltage
is different when the door stops closed or open, because in open position a torque to keep the
position is needed.
The motor voltage has to be checked with the Fermator programming tool.
You should change the motor if no movement is made when the voltage is present.
•
The door stops before the end of the learning cycle.
Verify the encoder :
- The door keeps open with no movement → sense of opening reversed, so interchange the 2
middle cables in the connector (55).
- The door closes and opens only 20 cm then stopping → encoder disconnected, encoder not
supplied or damaged, pulley screw wrong tight.
Change the encoder if nothing solves it.
•
The door opens instead of close.
- Verify the DIP switch 3 position.
- Reverse 2 phases of the motor connection (56).
•
The door makes the learning phase correctly but the skate stays open with the closed relay
active.
- Verify the switch 2 according to the correct open sense of the door. The door should be close in
the motor zone with the skate closed too.
•
The door stops in the skate zone.
- Verify by hand the correct and soft movement of the skate (see the assembling manual).
•
The door does not close completely.
- Disconnect the whole system and verify that no obstruction happens.
TEST always in this way in order to obtain the correct movement and verify in a well known
schedule.
If the autoadjustment was correctly passed, then the connections with the lift controller. The 3
potentiometers can be regulated too.
A Connect the cables coming from the lift controller.
- Connect the inputs cables (8, 9, 10, 11 and 12) and priority inputs cables
(26, 21, 25 and 23).
- Connect the photocell (17, 18, 19 and 20).
- Connect the relays outputs cables that inform the lift controller (30 to 41).
