Particularly, may cause safety problems to the system and to the passengers, if you do not respect the
instructions of this manual, about :
- motor/pump power on and power off
- soft stop sequence
- sensors S1, S2 ed S3
WARNING
The automatic return to the landing in event of lack of voltage should be made moving the car to the
lowest floor. Returning to a landing floor that is not the lowest floor, may cause safety problems to the
system and to the passengers
Never move the sensors S1 S2 S3 !
The sensors are installed, adjusted and tested at the factory.
The change of their position should be performed only by authorized and
properly trained people.
Moving the sensors may cause safety problems, to the system and to the
passengers.
Displacing the sensors voids the warranty.
IMPORTAN PARAMETERS
5.11 Mode
The factory setting is : INSTALLATION
It's possible to change the parameter to NORMAL onlyafter you have completed:
•The installation of the main parties (car)
•The connection of all the signals of the shaft
5.4 p_stat min and
5.5 p_stat max
The parameters are adjusted at the factory on the following pressures:
Pmin (P min> = 12) = pressure calculated with empty car
(or Pmin of the motor / pump - 20)
Pmax = pressure with car fully loaded.
After the installation, to check reading the parameter (Menu 1.1), that the values match those entered and if
theyare different correct them with the ones detected.
These values refer to the run curve in NORMAL mode, and they are ignored in INSTALLATION
mode
All other parameters do not affect the installation, but are used to regulate in detail the system
working in NORMAL mode
ALARMS
ALARM ?
To prevent the appearance of some alarms is sufficient that :
•The pressure is at least 7-8 bar (Menu 1.1)
•The oil temperature is at least 5-8 ° C (Menu 1.2)
•he motor / pump will start only after the RUN signal, sent from the card
(Menu 1.5 output parameter N)
In case of alarms see the troubleshooting section of this manual and follow the
directions.
If you do not find a solution to the problem call for service.
SWITCH TO NORMAL MODE AT THE END OF THE INSTALLATION
1. Use the PT01 programmer to modify the parameter value 5.11 Mode = Normal
2. Verify that the following parameters (menu 5 Setting) are correct :
- 5.1 Lift Ratio : must match the value shown on the project layout
- 5.2 Jack Diam : must match the value shown on the project layout
- 5.4 Pstat min : with empty car must be equal to the value of the menu 1.1 Pressure
- 5.5 Pstat max : with car fully loaded must be equal to the value of the menu 1.1

1.2 LA SCHEDA NGV-EK01
The NGV-EK01 card
- Is designed for applications where you can not install a power unit with
a standard NGV A3 valve and in particular for those installations
where the interface with the control panel is typical of a power unit
with the 3010 valve or similar.
- Is particularly suitable in event of restructuring, modernization and / or
where the control panel, born to operate with a power unit with 3010
valve or similar, it is not suitable to be used with a standard NGV-A3
valve.
The NGV-EK01 card, also
- Can be extended with an additional device in order to manage the
uncontrolled movement of the car (amendment A3).
The NGV-EK01 card coupled to a power unit with NGV-EK valve, is
advantageous because :
- Can be installed on any system in which the control panel, both
existing and new, does not meet the requirements to control of a
power unit with standard NGV-A3 valve.
- interfaces itself with the control panel only using terminals and do not
requires changes to the electrical/working schema
- the absorbing power is less than two solenoid and does not require
changes to the control panel.
- the use of a bypass valve that allows the starting of the motor-pump
with the VB spool closed, makes easier the interfacing with the control
panel.
- Indicates the alarm status via a single relay contact (exchange
contact).
1.3 IL FLUIDO
GMV use and recommend an hydraulic fluid ISO VG 46 that :
- Thanks to classification as category HEES, as rule ISO-UNI 6743-4
and its biodegradability index > 90%, according to standard CEC L33-
A-93, is acceptable from an environmental point of view.
- Thanks to the synthetic base (ISO VG 46 ) and its viscosity index
(>140), higher than the traditional mineral oil, allowing greater stability,
ensuring better performance against wear and aging on systems as
lifts for persons and goods, in accordance with the environmental
directive 2006/118/EC.
- Thanks to a flash point above 220°C compared to the 140°C of the
traditional mineral oil it is safer and reduces the risk of fire.
1.4 HOW THE NGV EK WORKS
The NGV valve 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).In case of
uncontrolled movement the P spool operates to avoid the lift downward
Valve VR It is a valve that prevent , during the downward, the oil inlet to the pump.
It forces the oil coming 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 VMD valve
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 screw-nut
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)
Valve
VBP This solenoid valve controls the fluid flow from the motor-pump towards the valve, and
consequently towards the piston. The VBP, when de-energized deflects the flow in exhaust,

(by-pass) when excited directs the flow towards the valve, allowing then to be able to supply the motor
pump with the VB spool closed. The valve is energized after the VB opening and it is de-
energized at the end of Soft Stop or when occurs an advance interruption of the manoeuvre.
All the other valves have features of safety, pilotage, etc. For example :
MPS+OPP Maximum pressure valve with pilot
5 Overspeed screw
VSMA Emergency lowering valve
1.5 THE DOUBLE SAFET
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 upward 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 pre
ssure 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.

•Cut at 90° the head of the pipe with a saw (do not use a pipe-cutter)
•Do not let metal residuals fall into the pipe 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 pipe against its stop to avoid the rotation, 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 pipe has all around a well
risen border. The border must cover 70% of the front part of
the cutting ring.
•Fix the pipe, 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 there is no dirty inside the tube. The impurities could damage the sealing of the piston and of
the valve block and inhibit the correct operation of the plant.

3.1.1 HOW TO INTERFACE
Different interfacing modes are provided with the various existing configurations of the control panel, settable
by the PT01 programmer through the menu.In case of failure to supply directly the NGV-EK card with the
required voltage, you must use a suitable power supply, type-ALM 03, capable to provide the correct voltage
deriving it from the valve supply voltage available in the control panel. (01-02-03)
The solenoid valve VBP (by-pass) uses the same power supply of the VMD (already available in the control
panel). Consequently, to connect it to the card, just provide only one terminal,since it is busy only for the
upward while VMD is not powered.Therefore,you do no change the circuit layout (05-06)
There are 4 inputs for commands,mutually isolated from each other, signed VMP-VML-AUX-VD, with a
driving voltage independently configurable for each input in one of the two available ranges (04)
In case the control panel is not set for the Soft Stop and the Unintended Car Movement monitoring,just use
the lift shaft signals. On the same connector there is voltage-free changeover contact, to realize the filter-
signal stop for Soft Stop. These signals are combined with those of the existing sensors
WARNING
If the command for the upward solenoid valve (VMP) is not available it is necessary to use the device
MP-ISO in order to detect the motor-pump power.

3.1.1.2 SOFT STOP MODE
Using the parameter 6.10 you can set some different Soft Stop working way.
Mode 0 Soft Stop managed from the control panel.
The Soft Stop starts when the VMP signal fails
Mode 1 Soft Stop managed by NGV-EK01, LS normally open.
Soft stop starts when, during the re-leveling, the LS signal becomes active and the
time set with parameter 6.11 is elapsed.
Mode 2 Soft Stop managed by NGV-EK01, LS normally open.
Soft stop starts when, during the re-leveling, the LS signal becomes not active and the
time set with parameter 6.11 is elapsed.
Mode 3 Soft Stop managed by NGV-EK01, SC1 normally open.
Soft stop begins when, during the re-leveling, the SC1 signal becomes active.
Please refer to the application diagrams for details of interfacing (§ 3.3.1)
