inactive during re-
leveling.
Check whether the leveling signal is normal.
2B
Subcode 102: The
re-leveling running
speed exceeds 0.1 m/
s.
Check whether the encoder is used properly.
Err47
Shorting door
lock circuit relay
abnormal
Subcode 101: During
re-leveling or pre-
open running, the
shorting door lock

2s, but the feedback
is invalid and the door
lock is disconnected.
• Check the signal feature (NO, NC) of the
feedback contact on the shorting door lock
circuit contactor.
• Check whether the shorting door lock circuit
contactor acts properly.
2B
Subcode 102: During
re-leveling or pre-
open running, the
shorting door lock
circuit contactor has
no output, but the
feedback is valid for
continuous 2s.
Subcode 106: The
feedback from the
shorting door circuit
relay is valid before
re-leveling.
Subcode 103: During
re-leveling or pre-
open running, the
output time of the

Subcode 101: The
consecutive times
that the door does
not open to the limit

Err50
Consecutive loss
of leveling signal
Subcode 101:

is detected for three
consecutive times.
• Check whether the leveling and door zone
sensors work properly.
• Check the installation verticality and depth of
the leveling plates.
• Check the leveling signal input points of the
MCB.
• Check whether the steel rope slips.
