Channel comparison of
door circuit input

This error can appear if the voltage on
door input was on the threshold be-
tween state “open” and state “closed”
for more than 3s.
This threshold are is round about 80 ...
105 V for the 110 V version and
140 V ... 200 V for the 230 V Version
Check voltage on door input. If it is too
low while the doors are closed, correct
this. If checking the voltage leads to no
results, supply the safety circuit with an
online sinewave UPS.
Remark/explanation:
It is likely that this fault is caused by
unusually high EMC disturbances on the
safety circuit. An online sine wave UPS
solves the problem because it consist-
ently delivers a pure sine wave, even if
the sinewave is severely disturbed.

Comparison of floor
table and floor table as
received from the control
failed

Check the number and position of floors
stored in LIMAX Safe SG/SC and the
number and position of floors stored in
the lift control. The number of floors
must match. The floor positions stored
in LIMAX Safe SG/SC and in the control
must match with a tolerance of 50mm.
If this is not the case, correct the floor
table of the control or LIMAX Safe
SG/SC. If table of LIMAX Safe SG/SC
has to be corrected a new learn trip will
usually be necessary.
This error requires a special reset, see

although it is error level 2 NOC will open additionally to OC,
but opening of OC is not treated in the error level because the NOC will close again when lift is in recall
