4.15 Error messages during teach-in procedure
Error: Lift did
not go to top
floor!
During teach-in the lift could not reach the top floor.
Possible causes:
- Faulty door zone switch SGM or switching points for SGM set
incorrectl
- Lower prelimit switch VU has not switched off
- Upper prelimit switch VO has not switched on
Door error
Door closing error when starting the teach-in trip
Lift not in
bottom floor
Lift not located on the bottom floor when starting teach-in procedure.
The shaft switches must have the following states when starting
teach-in procedure (complete calibration or calibration shaft switches):
- door zone switch SGM switched on
- upper prelimit switch VO switched off and lower prelimit switch VU
switched on (if available) or reference switch SGE off (if available)
- SGO and SGU (if available) switched on
Teach in not
possible, check
lift state!
Tech-in not possible because actual lift state is not "Setup" (e.g.
Inspection, Emergency recall operation, error state).
Time exceeded
Exceeded time between 2 status changes of SGM, SGO or SGU
during teach-in (see parameters "triptime[s]").
State changed.
New state:
Xxxx
Lift state changed during teach-in (e.g. error state or emergency recall
operation switched on)
Floorcount error
Check SGM
The door zone switch SGM has switched too often during the teach-in
procedure (e.g. due to bouncing of the switch).
VO switched
in doorzone
Upper prelimit switch VO switched while the lift was inside the door
zone. Check switching point.
VU switched
in doorzone
Lower prelimit switch VU switched while the lift was inside the door
zone. Check switching point.
SGE switched
in doorzone
Reference switch SGE switched while the lift was inside the door
zone. Check switching point.
Error on SGO
Upper door zone switch SGO not working during teach-in.
Error on SGU
Lower door zone switch SGU not working during teach-in.
Position of SGO
wrong!
Error in switching sequence SGO (SGO switched at undefined or at
wrong position). Possibly SGO and SGU are reversed.
Position of SGU
wrong!
Error in switching sequence SGU (SGU switched at undefined or at
wrong position). Possibly SGO and SGU are reversed.
Count direction
wrong!
Counting direction of the position encoder incorrectly. The two
channels of the encoder must be changed.
Setup position
switch not done!
The teach-in of the braking distance was started before teach-in of the
floor positions (magnetic switches) was finished.
Encoder is not
counting
No signals from encoder during teach-in trip.
Check encoder and wiring!
Encoder error
Irregular encoder signals during teach-in trip. Check encoder and
wiring!
Door zone too
small for stop
distances!
Check settings!
In normal case, the door zone (SGM or parameter "Vane length" if
using absolute encoder) should be adjusted so that the point where all
spped signals will be switched off is located inside door zone. The
