- Visually check the safety relays K5/K6/K7 (deformed contact pins)
- Check the connection KMPRO to KMREL board
The control contact of safety relay K5 reports a permanently inactive relay despite having left the zone.
The control switched into “out of operation 6“
The control stops in the next possible landing.
The control stops in the next possible landing and descends into the lowest landing from
there.
- Check selection signals SM/SZ (First SZ and then SM must turn active when approaching the zone.)
(Pay attention to the LEDs over the relays)
- Check selection signals for voltage (When a signal is active one should be able to measure a 24V
voltage between the signal and +24V.)
- Check the DIL switch „S1“ on the GENIUS20-relay board (All switches must be positioned on “off”)
- Check the jumper „J3“ (refer to the wiring diagram)
- Visually check the safety relays K5/K6/K7 (deformed contact pins)
- Check the connection KMPRO to KMREL board
S1 interruption in normal mode
The safety circuit 1 was interrupted during travel.
Due to the interruption of the safety circuit the lift is forced to stop and the control switches into “Out-
of-operation” mode.
- Main switch was switched off
- Safeties MCB FC has triggered
- Speed governor or lift arrestor contact have triggered
- Other contact before the S1 tap has triggered (refer to the wiring diagram)
- Measure voltage between S1 and NIN
- If no voltage can be detected, check the safety circuit contacts
- If some voltage can be detected but is not indicated properly by the control it might that the
optocoupler on the KMREL board is defective. Replace optocoupler or KMREL board.
S1 interruption in inspection mode
The safety circuit 1 was interrupted during travel
Lift stops and no further inspection run can be carried out
- Main switch was switched off
- Safeties MCB FC has triggered
- Speed governor or lift arrestor contact have triggered
- Other contact before the S1 tap has triggered (refer to the wiring diagram)
- Measure voltage between S1 and NIN
- If no voltage can be detected, check the safety circuit contacts
- If some voltage can be detected but is not indicated properly by the control it might that
the optocoupler on the KMREL board is defective. Replace optocoupler or KMREL board.
