What To Do If; Technical Features - Nice Mindy A924 Manuel D'instruction Pour L'installateur

9) What to do if...

Some of the most common problems that can occur during installation are indicated below.
• No Led is on:
check terminals 1 and 2 for mains voltage and make sure fuses F1 or F3 have not blown.
• The manoeuvre does not start:
check that the safety input led's "Stop", "Photo" and "Photo2" are active and that the motor is blocked (release led off).
• The direction of movement is inverted during the manoeuvre:
check that no safety devices have triggered ("Photo" in the closing manoeuvre and "Photo2" in the opening manoeuvre) or that the current
sensitivity device has not cut in; in the latter case check that the adjustment is sufficient for the movement of the door. If this is not the
case, increase the level by rotating one of the two trimmers clockwise (TR2 for opening, TR1 for closing).
• The "OK" led flashes quickly:
the input voltage is insufficient or an incorrect combination has been selected with the Dip switches.
• The motor moves slowly:
if it was previously released, the control unit is performing an alignment operation; the first cut-in of the current sensitivity device is
considered as a mechanical stop and the correct position is recalled from the memory.
• The motor performs the acceleration phase and stops:
check whether the encoder led flashes while the motor is moving. The led may flash at different speeds depending on the speed of
movement. When the motor is stopped the led may be on or off depending on the position in which the motor shaft stopped.
• The "OK" led remains on for a few seconds immediately after a command:
this shows there is a fault in the motor command stage; check the wiring and earth connection of the motor, other wise replace the
control unit.
