H2 H3 Description of reason for abort
yellow green
* - Same as 82, but learning the force to close the
door
* - Timeout (25 sec) when opening the door, to door
position 5 cm before "door open"
* 0 Same as 83, but 5 cm before the position "door
open"
* 0 Same as 83, but 5 cm before the position "door
open"
- - The required torque is too large when learning the
force to open the cam
- The required torque is too large when learning the
force to close the cam
- Timeout (5 sec) on opening the cam, before learn-
ing the door mass
0 - Timeout (5 sec) until constant rpm was reached to
learn the door mass
0 Learning the door mass cancelled, as braking
distance not adequate (position 60% opened)
0 Necessary starting speed to learn the door mass-
was not reached
- Braking distance was too short to learn the door
mass (less than ½ motor revolution)
Learned door mass too large
Learned door mass too small
- - Learned reduction ratio outside the limits:
60 ≤ aipm ≤ 310) impulses/cm

Short-duration blinking
LED blinks
2 blinks The two diodes blink in an alternating rhythm (1 on / 2 off); (2 on / 1 off);...
2 blinks The two diodes blink with the same rhythm (1 and 2 simultaneously on or off)
2 blinks 2 blinks LED 1 blinks in an alternating rhythm with LED 2 and LED 3 (1 on, 2 and 3 off); (1 off, 2 and 3 on)
Tab. 30 Explanation of the LED indicators
Possible cause
> Same as 82
> Belt tension too weak (belt slippage)
> Same as 82
> Same as 82
> Cam blocked, incorrect cam path learned.
> Cam blocked, incorrect cam path learned.
> Cam or landing door lock jammed
> Currently no known cause
> Currently no known cause
> Frictional forces too high
> Door blocked
> Same as 92
> Incorrect reduction ratio or door mass too large
(hardware)
> Incorrect gear ratio aipm (impulses per cm of
path)
> Error when learning the impulses per cm of path
(aipm)
> The specified door path was not maintained
when closing the door.
