16. TROUBLESHOOTING

There is a fault if the State LED is blinking. The faults can be read by WPT.
16.1 THE DOOR DOES NOT MOVE
16.1.1 The door does not move at all
- Check that the power is ON. The POWER LED H80 must light up if D1 is connected and the circuit break-
er in the elevator control panel is ON
- Check WATCHDOG LED H20, switch OFF/ON or replace board in case it lights up.
- Check that the motor and encoder wires are connected correctly (plug X4 and X10) and the motor
is not overheated (<= 60° C).
- Check that the control panel is sending an Open or Close command (I1-I2/X1, Led I1, I2).
- Check if there is too high friction if door is moved manually. If the state LED flashes read the faults by
using WPT, switch ON/OFF or replace board in case it flashes.
- Check if the open force limitation is deactivated (S 1/7 OFF).
16.1.2 The door does not open
- Check that the OPEN command LED I1 lits up when an open command is present (I1/X1 low).
- Check that the CLOSE command LED I2 does not light up (I2/X1 not low). A close command overrides the
open command.
- Check that the landing door lock is not jammed.
- Check if the open force limitation is active (S 1/7 ON) and the friction is too high.
16.1.3 The door does not close
- Check that the CLOSE command LED I2 lits up or the Input I2/X1 is switched on COM.
- The closing force may be too low (or friction too high). Turn CLOSE FORCE potentiometer slightly clock-
wise to increase the closing force, but watch the maximum allowed force!
16.1.4 The door only partly opens or closes
- Check that the open and close signal times (LEDs I1, I2) from the elevator controller are long enough.
The door moves only as long as command is set.
16.2 THE DOOR DOES NOT REOPEN
- If no automatically Re-open is selected (DIP Switch S1/2 is OFF):
- To reopen the door, the elevator controller must receive either a reopen request signal from the door
electronics (REOPEN) or from an independently wired safety device (e.g. Photocell or Curtain of Light).
- For reopening the elevator controller must remove the close command and activate the open command
- If automatic Re-open is selected (DIP Switch S1/2 is ON):
- An automatic 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).
