8.2 The door does not reopen
- If no automatically Re-open is selected (DIP
Switch S1/2 is OFF):
- For reopening the elevator controller must
remove the close command and activate the
open command
To reopen the door the elevator controller must
receive either a reopen request signal from the
door electronics (REOPEN) or from an inde-
pendently wired safety device (e.g. Photocell or
Curtain of Light).
- If automatic Re-open is selected (DIP Switch
S1/2 is ON):
- An automatical Re-open process is caused by
the Input IPD or by the closing force limiter.
Check the following reopen devices
- Photocell or light cell (defect or dirty).
- Closing force limiter (force too high).
8.3 Faults causing reset or switch off
(STATE LED is blinking, blink
code(x))
- Over current (3) (e.g. Power stage short circuit)(
- motor or encoder short circuit, open wires
and/or missing signals (1).
- Internal electronic fault (3)
- Undervoltage (supply voltage is measured and
the power stage switches off if the voltage is
too low).
- mechanical end not found (>=3,5m) (5).
- door mechanically blocked (4).
8.4 Faults decreasing performance of
door
- Motor and/or power stage temperature too
high. The software reduces the power of the
motor (power stage). If temperature is never-
theless exceeding a higher limit, power stage is
shut down for cooling down a certain time (4).
- Low voltage supply like battery drive or low line
voltage supply.
- Reference switch faulty (5).
