7.2 TROUBLESHOOTING
ID
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 receives the
signal VS from control panel. Verfy that signals
RDY and RUN are according to the scheme
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 arrives 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 receives 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.
