Learn run (when the supply voltage is applied)
Table 3- 2 Starting a learn run when the line voltage is applied
Procedure
1. Push the door into the CLOSED position.
2. Disconnect the power supply from X3 (DC).
3. Press the learn run button (S401) and keep it pressed.
4. Connect the power supply to X3 (DC).
5. The learn run starts automatically and the learn run button can be
released.
6. During the learn run, the door is opened about 10 cm, and closed once
or twice at creep speed. The friction of the door system is then deter-
mined by opening and closing the door once through a range of 25 cm
at creep speed.
The door then opens and closes through its complete range of move-
ment at reduced speed. After the door has opened by approximately
15 cm, it passes through an additional short acceleration ramp to de-
termine the weight of the door.
7. The door parameters and the determined door width are saved when
the door is in the CLOSED position.
This means that the door width and weight are re-adapted and saved.
In addition, the default values for the driving curve parameters are
loaded and the speed limits are preset on the basis of the determined
mass and permissible energies.
8. Learn run completed.
Note: If the light barrier / DCPS is set to light barrier and no light barri-
er is connected or if the light barrier bypass is not inserted, the 7-
segment display shows "0".
