- detect malfunctions
- try to take care of safety during malfunction
- get the operator to recover from the defected state.
In case the result of the diagnostics shows unrecoverable malfunctions, the door
operator is considered as unsafe, and the door is set free for manual use. The user
is informed by blinking both of the LED’s in control unit.

Indication Possible Fault Corrective user interventions in defined order
1) Check the mains.
2) Remove 12 pin connector from the control
board.
3) Measure the voltage from 5 pin connector,
connection points 1 and 3.
If voltage is under 24VDC, change the power
supply unit.
4) Measure the voltage from 12 pin connector,
+24V out against GND.
If voltage is not 24 VDC, change the control
board.
1) Teach the door open and close positions .
2) Check all impulse devices and connections.
3) Check fire detector connection and fire N.C.
jumper.
1) Check that 1000 ohm resistor is connected in
control board or in safety sensor.
2) Check that cables are not damaged.
1) Move obstacle from safety sensor detection
area.
2) Check that cables are not damaged.
1) Switch main switch off for 10 seconds.
2) Check that all applicable jumpers are in place
(one of the two arms is selected, “single” is
selected).
3) Teach the door open and close positions.
4) Change a spare control board.
1) Switch main switch off for 10 seconds.
2) Check that all applicable jumpers are in place
(one of the two arms is selected, “single” is
selected)
Check position sensor’s cable and connector.
3) Teach the door positions.
4) Change a spare position sensor.
