Err 36 E36
Contact
feedback
abnormity
1 .Running contactor is not
pulled in when the brake is
open;
2 .When lift continuously
runs over 1 second, the
contact feedback signal is
lost;
3 .The contactor feedback
signal conglutinates;
4 .No feedback signal after
the contact closed;
1 .Detect contactor and
feedback contact;
2 .Detect whether the
controller output wire
U,V,W is normal
3 .Detect that the
circuit power of contact
controlling is normal or not;
5
Err 37 E37
Brake
feedback
abnormity
The brake output is
not consistent with the
feedback signal .
1 .Detect that the brake
coil and feedback contact;
2 .Notarize the signal
character of the feedback
contact (N .O .or N .C .);
3 .Detect that the circuit
power of brake coil
controlling is normal or not;
5
Err 38 E38
Controller
encode
signal
abnormity
1 .No input encode pulse
when lift is automatic
running;
2 .The direction of input
encode signal is wrong
when lift is automatic
running;
3 .Set to open-loop (F0-00)
when in distance control;
1 .Ensure encoder using
right;
2 .Replce encoder
’
s A,B
phase;
3 .Detect the setting of
F0-00, and change to
close-loop control;
5

Motor overheated and
relay output valid
1: Lift
’
s speed is too low
or the floor is too high
2: Improve the motor

Err 40 E40
Lift run
overtime
The setting time of lift
running is up .
1 .Lift speed is too low or
the floor is too high;
2 .The lift is used for a
long time and needs
maintenance;
4
Err 41 E41
Safety circuit
off
The signal of safety circuit
is cut .
1 .Detect safety circuit, and
look over its state;
2 .Detect whether the
exterior power supply is
normal
3 .check the safety loop
contactor action
4 .check the safety loop
contactor feedback contact
singal (N .O, NC)
5
Err 42 E42
Door lock cut
in running
The door lock feedback is
cut when lift is running .
1 .check the hall and car
door-lock
2 .check the door-lock
contactor
3 .check the door-lock
contactor feedback contact
singal (NC, NO)
4 .Check the external
power
