NGV A3 VALVE MANUAL
INSTALLATION, USE AND MAINTENANCE
1.3 HOW THE NGV A3 WORKS
The valve NGV is made with a non-return valve VR, a control spool VB controlled by a stepping motor and by
a system with pilot operated non-return valve VRP - P
(moved in opening by the electro-valve VMD)
Valve VR
It is a valve that prevent , during the downward, the oil inlet to the pump.
It forces the oil that comes from the VRP C2 to pass through the spool VB and then in the
C3 and in the tank T1.
Valve VRP-P
It is the pilot operated non-return valve, requested by rules.
During upward the valve works only as ON/OFF, the spool VRP opens or closes
depending on the oil that comes. Its position is determined by the ratio between the
pressure that develops in the chamber C2 and the one that occurs in chamber C1
During downward, instead, it opens the oil way to the valve block (chamber C2).
Its opening is made by the pushing of the piston P that is opened by the pilot operated
valve VMD
Spool VB
It’s the main part of the control block.
It adjusts the oil quantity that should be discharged and determines all the movements of
the car
Its movement is controlled by a stepping motor coupled to the spool VB, through a screwnut coupling (necessary to transform the rotatory motion into translatory).
The spool adjusts both the upward phase (with a direct control of the oil that should be
discharged and, indirectly the oil for the cylinder) than that of downward (directly)
All the other valves have features of safety, pilotage, etc. For example :

1.4 THE DOUBLE SAFETY
For the double safety the system has two spools in series, the VRP and the VB.
Both work together to stop the car in different ways between upvward and downward
UPWARD
The spool VB controls acceleration and deceleration.
During the approach to the landing, the spool VB, will be almost fully open to discharge a quantity of oil
equal to:
Qt = Qp - Qc
where
Qt = Oil sent to the drain through the VB, Qp= Pump flow
Qc= Flow to the cylinder, corresponding to the car speed
The car stop at the landing is made by opening completely the VB and bringing the value of Qt = Qp. As a
result Qc becomes zero.
The car stops when the pressure of the chamber C2 become equal to the pressure of the chamber C1
(Static pressure of the system). In this case,
the VRP spool closes, because is pushed by the pressure and
by the spring, and the car stops at the landing.
DOWNWARD
The downward phase is simpler and, after the opening of the VRP spool, the car speed is controlled by the
VB spool. To a more opening of the spool corresponds an higher speed of the car
The phase of arrival at the landing is determined by the following events:
The VRP spool is opened by the push of the spools P, controlled by the VMD pilot valve
The VB spool closes to stop the car
The VMD valve, raised the landing, is de-energized and consequently the VRP spool closes.
During standard operation of the system, both upward and downward, the proper working of the two
spools (VRP and VB) acting in series, is controlled by three switches :
One, (S1) installed on the VRP, to control the full close position.
Two (S2, S3) installed on the VB, to control the full close and the full open positions
During all phases the system control that the spools reach the correct open and close position.
If this do not happen, the system send an alarm to the control panel, which must turn the system into the
out of service status
WARNING
Needful prerequisite of the control panel, when the system is outside of the doors unlocking zone, is
that it does not send commands to the card and/or the motor / pump.

WARNING
The control panel, when receive a FAULT signal from the NGV-A3 card (RUN and RDY output),
should not send commando to the valve and/or the motor/pump
In FAULT condition the motor/pump group should NOT be active
WARNING
To detect the unintended movement of the car the system use the circuit required by paragraph 7.7.1
and 14.2.1.2 of the rule EN 81-2:2010. This circuit, if it detects a movement of the car, with doors not
closed, outside the unlocking zone, prevents the control panel to send any command to the valve.
The system restore should be performed only by an authorized and properly trained person.

2.3.3 FAULT SCHEMAS
A control panel installed with the valve NGV A3 must continuously monitor the signals RDY and RUN (UP)
that it receives from the card NGVA3-xx.
The control panel should go in error status, stop the system and do not send commands to the valve and / or
the motor / pump when, for more than 2s, signals RDY and RUN are simultaneously in the same condition.
The contemporary of the ON or OFF status require different behaviours, in particular:
If RDY and RUN are both in ON status, the control panel must detect the error, move the car to the nearest
landing and stop the system without allowing more travels;
If RDY and RUN are both in OFF status, the control panel must stop immediately the system and prevent any
further movement with the exception of the manual emergency operation.

2.8.1 CONNECTION WITH FLEXIBLE HOSE
· Remove the gear and the cutting ring from the terminal
connection of the silencer.
· Ensure that the terminal connection is well fixed on the
silencer.
· Clean and oil the threading and their seats.
· Fix the flexible hose verifying it is thoroughly tightened.
WARNING
Ensure that there is no dirty inside the tube. These
impurities could damage the sealing of the piston and of
the valve block and inhibit the correct operation of the
system.
2.8.2 CONNECTION WITH A RIGID PIPE
· Cut at 90° the head of the tube with a saw (do not use a tube-cutter)
· Do not let metal residuals fall into the tube and eliminate the burrs internally and externally.
· Remove the gear and the cutting ring of the terminal connection and insert it on the pipe.
· Ensure that the cutting ring is inserted as indicated in image
· Ensure that the terminal connection is well fixed on the silencer.
· Clean and lubricate the threading and the connection seat with
a slight oil veil.
· Insert the pipe into the cone at 24° up to lay it on the stop limit
of the cone itself.
· Screw thoroughly the gear by hand until it is felt that the cutting
gear lays perfectly to the nut.
· Then screw the nut using a wrench until the cutting edge of the
ring is in contact with the tube and prevents it from rotating.
· Keep the tube against its stop to avoid it rotates, screw the
fixing nut by 3/4 rev. In doing so the ring engraves with the
necessary depth the external part of the tube and rises a
border in front of its cutting edge.
· Loose the nut and check that the tube has all around a well
risen border. The border must cover 70% of the front part of
the cutting ring.
· Fix the tube, close the nut with a wrench until a certain
resistance is felt; from this moment on screw for a further 1/4
turn, contrasting wrench against wrench.
WARNING
Ensure that there is no dirty inside the tube. These impurities could damage the sealing of the piston
and of the valve block and inhibit the correct operation of the plant.

6 MAINTENANCE AND FAULT ANALYSIS
6.1 PROGRAMMED MAINTENANCE
For a correct and safe lift use, it is necessary to make a preventive programmed maintenance, following a
fixed plan.
To define the periodical maintenance frequency, you should consider more events, particularly :
- Number of travel per year
- Travelling and stopping periods
- Age and condition of the lift
- Site and type of the building in which the lift travel
- Passengers and goods demand
- Inside and outside working condition (climate, vandalism, etc.)
In the next table, parts are shared in groups and for each group is shown the type of check and its longest
frequency recommended. Checks operative instructions are detailed in the maintenance schedules on
chapter.
Please, note that all checks are applicable only if the part is really installed..

What to do: (see image)
Valve gaskets seals
- At the end of installation, and during check-
ups, verify the gasket seals, in the following
way: with the oil at room temperature close
the ball valve (B) and open the pressure
gauge shut off (4). Check that the pressure
gauge reading on pressure gauge should
not drop more than 4 bar in 5 minutes.
Oil level check-up.
- With the elevator at the highest floor, check,
using dipstick (F) or level indicator (L), that
the oil level is above the minimum level and
(the motor should be fully covered in oil).

Oil Characteristics
- Check visually that no change are occurred in the oil conditions. Perform this check after leaving the
system down for a few hours. Once every year it should be better to discharge a little amount of oil
from cap (J) and to check if it’s clean. If oil is not clean keep on discharging oil until you see to flow
clean oil.

- Check static and dynamic (working) pressure at the end of installation.
Check regularly that all values of these parameters remain unchanged.
Pressure gauge shut off (4)
- Close the ball valve (B), open the pressure gauge shut off (4) and fully discharge the pressure using
electro-valve (VMD). Close the pressure gauge shut off (4) open the ball valve (B) and check that the
level shown on pressure gauge is zero.
Pressure test (static pressure x2)
· This test assures you about the integrity of parts under pressure, including those which can not be visually
checked.
· To correctly carry out this test follow these instructions and make reference to the images:
- Close the pressure gauge valve (4).
- Close the ball valve (B). Remove the pressure gauge (MAN).
- Connect the hand pump (M) in place of the pressure gauge (G1/4) as
shown in the image on the right side
- Open the pressure gauge valve (4).
- Open the ball valve (B).
- Open the hand pump valve (N) for about 1 minute.
- Close the hand pump valve (N).
- Close the ball valve (B).
- Operate the hand pump (M) until the required pressure is reached,
checking it on hand pump pressure gauge (O).
- At the end of the test, discharge the pressure to zero by pressing the
push-button on (VMD) (see image up).
- Close the pressure gauge shut off (4).
- Disconnect the hand pump (M)
- Mount the pressure gauge (MAN).

P – Pump fitting
Q – Cupper washer
Labels, signs and schemes
- Check that all the tags and diagrams are in place and legible (oil data label, emergency operation
manual, electrical diagram and hydraulic power unit schemes).
Overall check-up
- Perform an overall check up of the power unit. When the overall check-up ends, check all the settings
for the power unit start-up.
· Replace or restore all the components not correctly working.
NOTE
In case of oil replacement, do not throw the oil away in the environment, but give it to oil recycling
company.
NOTE
When the power unit in no longer required, don’t throw it away, but give it to a recycling company or to
the manufacturer.

contact support). If the problem
persist on the sensors S2 e S31
probably the stepping motor does
not work correctly (verify and
eventually replace) or not work
correctly the VB (verify and/or

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.

The system
- do not stops at landing
The signal VS or D do not
switch off or is switched off
too late (up to 1-2 cm from
floor)
The deceleration speed or
the levelling speed is too
high.
Verify (menu 1.4 S0123DICA) that the
signal VS or D is switched off before that
the car arrives at floor, at the beginning of
the deceleration zone.
If the signal do not change status check
the signal flow from the control panel and
repair the error.
If the problem persist, verify the
parameters set in Menu: 4.2, 4.4, 4.6 e 4.8
and if are not the default value set to
default (default = 0). Verify that the value of
parameters 6.4, 6.5, 7.4 e 7.5 is the
recommended value. (see § 5.3)
If setting parameter to the default values
do not solve the problem, you should
personalize the value set in the Menu: 4.2,
4.4 (min = car empty), 4.6 e 4.8 (max = car
with full load).
10
The system
stops during the switching
from nominal speed to slow
speed; with the car empty or
full loaded.
If the basic settings are
correct (Menu 5) the slow
speed (6.4 and 7.4) or the
low speed offsets (4.2, 4.4,
4.6 e 4.8) should be too low.
Input the recommended values for the
menu points 6.4 e 7.4 or increase the
offsets of the slow speed (4.2, 4.4, 4.6 e
4.8)
11
The control panel detects an
insufficient minimum
pressure
The system minimum
pressure is below the
minimum allowed or control
panel and card do not work
with the same type of signal.
(the card send a normally
close (NC) signal and the
control panel works with a
normally open (NO) signal).
Control (Menu 1.1) the pressure value of
the system, if the value is below the
minimum (5.7 bar) and the red led is switch
on, you must increase the minimum
pressure of the system.
If you have no error on the card and the
minimum pressure is higher than 5.7 bar
you must verify that the card and the
control panel have the same type of signal
(both NC or both NO)
