N. Fault Type Description Remedy
3
Low speed too
long
Car moving at low speed for too
long. In case of VVVF may be too
low engine torque in the
approching floor phase.
Check:
1- Check parameter “Low Speed fault
time” (§ 5.5) and increase time if
necessary
2- the elevator speed to a low speed (in
the case of VVVF); increase it if
necessary
3a- the decelarating distance to the
plane indicated (magnets / flags FAI /
FAS)
3B- value of the distance R1D / R1S if
Encoder is used (§ 5.9)
4 Overload
Overload input (SUR) activated
(NO contact)
Check
1- the SUR input (if locked) and wiring
2- the setting of the load weighing device
5 Positioning fault
This error shows a difference
between the performed theoretical
counting and the real position
detected:
FAI/FAS: at the activation of the
AGB/AGH limit contacts;
ENCODER: at the activation of the
AGB/AGH limit contacts (cod 0)
and at the activation of ZP magnet
floor (cod 100) or stop level’s ZP
magnet floor (cod 200)
Check:
1- the correct positioning of the magnets
(or flags)
2- operation of magnetic reeds, optical
detector or encoder; verify the arrival of
24V current
3- the distance between extreme contact
and magnet (or flag)
6 Direction fault
The controller detects the wrong
direction of travel
Check:
1- the direction of travel of the engine
(control UP vs. Car movement direction)
2- the installation and connection of FAI /
FAS sensors
3- CW / CCW Encoder configuration (§
5.9)
4- AGH and AGB inputs
7
Safety 3 open at
stop
Safety chain interrupted with
elevator not running. Calls are
deleted. On the PlayPad Led SE3
is off.
Check all contacts between the terminals
SC2 and SE3 (Safety Gear, Limit switch,
Overspeed Governor).
9 Door lock fault
Safety chain open at point SE6
when a call is registered
With automatic door: door re-
opens and then closes (3 times,
after which all calls are cancelled).
Other door types: after a few
seconds all calls are cancelled
Cod 5: floor locks
Cod 6: car door
Check all contacts between the terminals
SD2 and SD3 (floor locks) or SC4 and
SC5 (car doors) according cod info, their
connection and if an object obstructs the
closing of the door to the indicated floor
(POS).
In case of 81-21 devices check its
contacts in Normal mode operations.
