10.4.6. Testing the white lamp
If the lamp does not turn on, proceed as follows:
1. To test the lamp, press its lamp cap (1 in Fig. 10-10).
• Lamp does not turn on:
– Lamp is burnt out
– Lamp-test circuit is faulty
The lamp-test circuit and the door releasing circuit are independent of
each other. From the lamp not lighting up, it cannot be concluded that
the door releasing circuit is not working.
• Lamp turns on:
– Door releasing circuit is malfunctioning.

2. Check if the LED of digital input DI07 (input module A2531 in COU1) is lit.
• If the LED is lit, the drive control system receives the feedback signal
"grounding switch is closed", but the control system has not released the
doors.
• If the LED is not lit, the feedback signal is missing.
