Description
The lower prelimit switch VU
switches within the door zone
(incorrect shift position).
One possible cause is that one
of the door zone switch has not
switched off.
The switching state of at least
one of the prelimit switches VO
or VU is wrong (for example
both switches on or lift in
lowest floor, but VU is not on).
This error message may also
occur if the door zone switches
SGO/SGU are not working
well; so the lift controller may
have miscount the floor
number.
According to the measurement
of the positioning system the lift
is located inside door zone, but
the door zone switch SGM is
off.
Possible reasons:
- switch SGM defective
- Positioning system defective,
for example incremental
encoder not connected well).
According to the measurement
of the positioning system the lift
is located outside door zone,
but the door zone switch SGM
is on.
Possible reasons: see above.
The feedback signal from the
safety circuit for moving with
open doors was not activated
while the lift was entering the
door zone.
The feedback signal from the
safety circuit for moving with
open doors was not
deactivated while the lift was
leaving the door zone.
Lift stops before reaching the
99/196
Lift controller reaction
See above
Emergency stop.
Back to normal operation if all
position switches have the right
state again (see switching
sequence diagram in lift
schematic).
Emergency stop.
Back to normal operation if all
position switches have the right
state again (see switching
sequence diagram in lift
schematic) and the positioning
system is counting well again.
Mainly a reset is necessary.
If the motor encoder is used as
positioning system this error also
may occur during technical test. In
this case a reset has to be
performed.
See above
Emergency stop.
Back to normal operation if
feedback signal is switched on
again.
Check safety relais on HSE (KH5,
KH6, KH7) and poitioning system /
doorzone switch).
