Fault
Type
Description
Remedy
26
Running time UP
No change in the beam status for
motion sensors (or floor) for more
than planned during car travel. In
case of encodeur the threshold is 1
sec. over AGB/AGH limit point
Cod 0: problem on FAI FAS input (no
changing of inputs for time longer
than “Running time” parameter
Cod 100: problem on encoder
channel
Cod 200: no changing of ZP input for
time longer than “Running time”
parameter
Check contactors, brake, motor power
supply, FAI/FAS sensors (or
ENCODER).
Check “X1” and “12” inputs of the VVVF.
Anti-slippage test:See Annex II – Test
and measures
27
Running time
DOWN
See above but in downward
movement
See above but in downward movement
28
Door A closing
slippage
Only doors with limit switch:
Door A does not close within
programmed time.
3 complete opening/closing cycles are
performed, then all registered calls
are cancelled
Check:
1- door close limit switch FFA (NC
contact) and wiring
2- door motor power supply and fuses
3- door close contactors (RFA)
29
Door B closing
slippage
Same as door A, for second entrance
Same as door A, but signals (FFB) and
(RFB)
30
Out of service
switch
If the relevant parameter has been
programmed, it indicates that the
system has been put out of service
through the activation of input HS
Cod 0: Key HS activation
Cod 100: BDU’s key activation.
Cod 200: cabine key activation.
Check input out of service input (NO
contact)
Cod 0: input HS on screw temrinal
Cod 100: inut IN 2 on BDU
Cod 200: input SPARE on DMCPIT
31
FAI-FAS error
Simultaneous variation of FAI/FAS
positioning sensors. POS [n] indicates
that the error occurred at floor [n].
POS 100 indicates a wrong sequence
of beams
Check power supply to sensors;
Check sensors and magnets position.
32
Temporary op.
without insp.
During temporary operations the input
REV or REV1 or REV2 must be active
or the lift will not move.
Check input REV, REV1 or REV2 (NC
contact)
33
Stopping
accuracy
When the lift stops at floor, the two
FAI/FAS LEDs are on. If within 2
seconds from the stop one of the
beams is interrupted, this fault occurs.
If the system is equipped with
ENCODER the uncertainty of the stop
is more than 2 cm.
Check:
1- position of the magnets;
2- deceleration distances;
3- motor brake
34
Anti-nuisance
It appears after a call cancellation and
if the parameter “Anti-nuisance” has
been programmed.
The reason is too many calls from the
car without the cell being cut (in case
of combined doors) or without landing
doors opening (other door types)
Change number of unwanted calls in the
Anti-nuisance parameter
