Err37
Brake
contactor
feedback
abnormal
1. The output of the
brake contactor is
inconsistent with the
feedback.
2. When both feedback
signals of the brake
contactor are enabled,
their states are
inconsistent.
1. Check whether the brake coil
and feedback contact are correct.
2. Check the signal feature (NO,
NC) of the feedback contact.
3. Check whether the control
circuit of the brake contactor coil is
normal.
5A
Err38
Encoder signal
abnormal
1. There is no input
of the encoder pulses
when the elevator runs
automatically.
2. The direction of the
input encoder signal
is incorrect when
the elevator runs
automatically.
3. F0-00 is set to 0
(SFVC) in distance
control.
1. Check whether the encoder is
used correctly.
2. Exchange phases A and B of the
encoder.
3. Check the setting of F0-00, and
change it to CLVC.
4. Check whether the system and
signal cables are grounded reliably.
5. Check whether cabling between
the encoder and the PG card is
correct.
5A
Err39
Motor overheat
The motor overheat
relay input remains
valid for a certain time.
1. Check whether the thermal
protection relay is normal.
2. Check whether the motor is used
properly and whether it is damaged.
3. Improve cooling conditions of the
motor.
3A
Err40
Elevator
running
timeout
The set elevator
running time is
reached.
The elevator is used for a long time
and needs maintenance.
4B
Err41
Safety circuit
breaking off
The safety circuit signal
is cut off.
1. Check the safety circuit switches
and their states.
2. Check whether the external
power supply is normal.
3. Check whether the safety circuit
contactor acts properly.
4. Confirm the signal feature (NO,
NC) of the feedback contact of the
safety circuit contactor.
