6.4.1 TROUBLESHOOTING
Fault
Possible cause
Possible solution
1 The system
- do not start but the pump
works
The card do not receive the
signal VS from the control
panel.
The control panel do not
receive/recognize the RUN
signal from the card.
Verify in the Menu 1.4 if the card receive
the signal VS from control panel. Verfy that
signals RDY and RUN are according to the
schema 2.3.3
2 The system
- run slowly in up and down
direction
- stops immediately without
deceleration
The Menu 5.12 is set on
“Install” and the system run
only in inspection speed.
The default parameter is “Install”. At the
end of the installation you must set the
parameter 5.12 = “Normal”
3 The system
- run only with low speed
The card
- do not receive the speed
signal (V0, V1, V2)
- receive the speed signal
after the direction signal (VS,
D)
Verify (menu 1.4 S0123DICA) that the card
receives the speed and the direction
signals.
If the card do not receives any signal check
the signal flow from the control panel and
repair the error.
4 The system
- has an abrupt departure in
up direction (run fast for
piece of the travel, slows,
and return to the correct
speed.
The motor starts before of
the RUN signal
Verify that the signals RUN and RDY are in
compliance with § 2.3.3. Verify (menù 1.4
S0123DICA) that all signals are received
and (menù 1.5 1234YND) send correctly
to/from the card.
The motor do not must start before:
- VS, up command
- RUN
- Out 4=UP if used
5 The system
- starts in up direction with
an not regular acceleration
(it starts with a little burst
and immediately return to
the correct acceleration)
The starting time is not
correct, the oil output line
was open in advance and
the oil reach the piston until
the motor is at full.
Increase the value of the menu point 6.8 to
delay the oil output line opening.
6 The system
- run irregularly and
inaccurate
The basic parameters are
not corrects
Verify (menu 5) that the values set are in
compliance with the effective system data.
Particularly, verify values 5.5 Pstat MIN e
5.6 Pstat MAX
7 The system
- stops over/under the
landing level when the
system has a reduced floor
distance (< 1,8m)
The system arrive at landing
in nominal speed (Vo)
instead of intermediate
speed V1.
The intermediate speed set
is too high
Verify that the card receives the speed
signal V1 (menu 1.4 S0123DICA). If the
card do not receive the signal check the
signal flow from the control panel and
repair the error.
If the card receive the signal you must
decrease the intermediate speed V1
parameter (in up direction menu 6.2, in
down direction menu 7.2 recommended
value 0,3 m/s) and/or increase the
deceleration distance.
8 The system
- do not decelerate correctly
The speed signals (V0, V1 o
V2) are not according with §
3.5 or the magnet position is
not correct
Verify (menù 1.4 S0123DICA) that the
status of the speed signal V0 changes from
1 to 0 when the car comes in the
deceleration zone.
Verify that the parameters 4.9, 4.10, 4.11 e
4.12 are correctly set (default = 0) and
otherwise, set the correct value.
Verify that the magnets are at the correct
distance from the floor
If the problem persist, please, contact the
technical support.
