Description
Lift controller reaction
- Field direction of power
supply wrong (change 2
phases)
176/15 Lift fast on VO
If moving upwards the upper
prelimit switch VO was
switched on while the lift was
still running with v3 (position of
VO wrong).
In general, the lift controller
must slow down the lift before
VO switches on. Only by lifts
with just 2 floors the prelimit
switches may be used as
slowdown switches.
Lift is slowing down to arrival
speed v0 if the prelimit switch goes
on.
Check and correct position of
prelimit switch VO.
If incremental or absolute encoder
(AWG) is used as positioning
system: check parameter "Dec. v3
↑
" and place the prelimit switch by
about 90% of this value before
highest level.
176/16 Lift fast on VU
If moving downwards the lower
prelimit switch VU was
switched on while the lift was
still running with v3 (position of
VU wrong).
In general, the lift controller
must slow down the lift before
VU switches on. Only by lifts
with just 2 floors the prelimit
switches may be used as
slowdown switches.
Lift is slowing down to arrival
speed v0 if the prelimit switch goes
on.
Check and correct position of
prelimit switch VU.
If incremental or absolute encoder
(AWG) is used as positioning
system: check parameter "Dec. v3
↓
" and place the prelimit switch by
about 90% of this value before
lowest level.
176/17 Magnet wrong
Only for positioning system via
"Switch": Switching sequence
of the position switches (door
zone switches, slow down
switch) wrong.
Stop in next floor.
Back to normal operation if all
position switches have the right
state again (see switching
sequence diagram in lift
schematic).
Check all position switches.
176/18 SGV in doorzone
Slow down switch SGV
switched inside door zone
(wrong position, see switching
sequence in lift schematic).
A possible reason is also, that
one of the door zone switches
did not switch off.
Stop in next floor.
Back to normal operation if all
position switches have the right
state again (see switching
sequence diagram in lift
schematic).
Check all position switches.
176/19 SGE in doorzone
Reference switch SGE
switched inside door zone
(wrong position, see switching
sequence in lift schematic).
A possible reason is also, that
one of the door zone switches
did not switch off.
Stop in next floor.
Back to normal operation if all
position switches have the right
state again (see switching
sequence diagram in lift
schematic).
Check all position switches.
176/20 Error SGE
State of reference switch SGE
wrong.
(wrong position, see switching
Stop in next floor.
Back to normal operation if all
position switches have the right
