Elevator System Fault List (Cont'd)
The safety protection function of safety circuit
board has acted, the door circuit break
because the car runs out door zone. System
reports door zone missing error, this error will
not recover until reset.
Because it will run out door zone, when door zone
misses, and brake force become invalid in same time. It
is for reminding maintenance staffs of solving door
zone missing error in time, and avoiding the car runs
out safety door zone while creeping.
The car meets unexpected sliding and during
releasing passengers, the signal of top limit
vibrates.
The sliding protection function of safety circuit board
has acted. After the system finds brake invalid, the
signal of top limit vibrates during upward creeping.
Then the safety protection will be stopped by top limit
error. This error will be latched and will not recover
until reset.
The car meets unexpected sliding and during
releasing passengers, the signal of bottom limit
vibrates.
The sliding protection function of safety circuit board
has acted. After the system finds brake invalid, the
signal of bottom limit vibrates during downward
creeping. Then the safety protection will be stopped by
bottom limit error. This error will be latched and will
not recover until reset.
The car meets unexpected sliding and during
releasing passengers, the signal of top terminal
vibrates.
The sliding protection function of safety circuit board
has acted. After the system finds brake invalid, the
signal of top terminal vibrates during upward creeping.
Then the safety protection will be stopped by top
terminal adhesion error. This error will be latched and
will not recover until reset.
The car meets unexpected sliding and during
releasing passengers, the signal of bottom
terminal vibrates.
The sliding protection function of safety circuit board
has acted. After the system finds brake invalid, the
signal of bottom terminal vibrates during downward
creeping. Then the safety protection will be stopped by
bottom terminal adhesion error. This error will be
latched and will not recover until reset.
Wrong parameters setting of unexpected
sliding protection.
Enable sliding protection, but not enable
door-open-in-advance and releveling function.
Signals of safety door zone miss.
Enable sliding protection but cannot detect safety door
zone signals at door zone.
Unreasonable parameter setting.
Check the following setting: Check if parking floor,
homing floor, fire floor is set to non-stop floor; Check if
both front and rear door of stop-able floor are set to
disable while in two door mode; Check if group control
is enabled while parallel control or two door mode is
enabled at same time.
Drive module overheat protection.
While running, the drive power module occurs
overheat protection.
The signals of up and down door zone are
reversed.
The signals of up and down door zone are reversed.
Exchange wirings of up and down door zone signals.
Changing speed is too late, which after running
through door zone.
Increase the minimum single layer velocity and curve
acceleration.
Haven’t used X31 as hall door detection, but
X31 is effective. Or have no door contactor but
X11 become effective.
1. Check if X31 is effective when F4-06-12 is OFF;
2. Check if X11 is effective when F4-06-13 is ON.
The minimum speed change distance is less
than the door zone segment magnetic plate.
Increase the minimum running speed of single floor.
