abnormal
101, 102: The feedback
of the RUN contactor is
active, but the contactor
has no output.
103: The controller
outputs the RUN signal
but receives no RUN
feedback within 2s.
104: When both
feedback signals of
the RUN contactor are
enabled, their states are
inconsistent.
101, 102, 103, 104:
•
Check whether the feedback
contact of the contactor acts
properly.
•
Check the signal feature (NO, NC)
of the feedback contact.

Err37
Brake
contactor
feedback
abnormal
101: The output of
the brake contactor is
inconsistent with the
feedback.
102: When both
feedback signals of the
brake contactor are
enabled, their states are
inconsistent.
101, 102:
•
Check whether the brake coil and
feedback contact are correct.
•
Check the signal feature (NO, NC)

Err38
Encoder signal
abnormal
1: SVC is used for non-
inspection running in
distance control.
2: In non auto-leveling
or shaft auto-tuning
state, the elevator runs
in the opposite direction
for more than 10 cm
(subcode 2 reported for
up direction, subcode 3
for down direction).
3: In non auto-leveling or
shaft auto-tuning state of
CLVC, the running time
exceeds FH-03 and the
F4-03 does not change.
1 to 4:
•
Check whether the encoder is
used correctly.
•
Check whether the motor running
direction is correct.
•
Check whether the system
grounding and signal grounding
are reliable.
•
Check whether wiring between
the encoder and the PG card is
correct.
5A
Err39 Motor overheat
101: The motor overheat
relay input remains valid
for a certain time.
101:
•
Check whether the thermal
protection relay is normal.
•
Check whether the motor is
used properly and whether it is
damaged.
•
Improve cooling conditions of
the motor.
