1FEATURES AND REQUIREMENTS
1.1 THE 3010 2 H A3 DISTRIBUTOR
The 3010 2CH A3 Distributor is a two-speed electro-mechanical valve with:
- the Fluitronic technology.
- the possibility to use ecological fluid or traditional mineral oil
- The use for slowing and stopping in normal operation of two valves operating in series, redundant and
electrically monitored
Guarantees:
- System reliability
- Constant downward speed regardless of the load
- The protection against unintended movement of the car (A3)
integrated.
- Compliance with various regulatory and environmental requirements
(Ex. compliance with the Directive 2006/118/EC on the environment)
Offers:
- Speed up to 0,8 m/s
- Downward speed greater than the upward (up to + 20%)
- Soft Stop function (optional)
1.2 THE FLUID
GMV uses and recommends a hydraulic fluid ISO VG 46 that:
- Thanks to classification as category HEES, as rule ISO-UNI 6743-4 and its
biodegradability index > 70%, according to standard OECD-301-B, 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/CE.
- Thanks to its flash point above 300°C compared to the 140°C of the traditional
mineral oil it is safer and reduces the risk of fire.
1.3 HOW THE 3100 2 H A3 SYSTEM WORKS
For the normal operation of the system in upward:
The VMP 2CH or 2CH / S solenoid valve must be initially energized for about 1s and remain de-energized
until the next call.
For the normal operation of the system in downward:
The VMP 2CH or 2CH / S valve is energized and de-energized simultaneously with the main downward valve
(VMD); it follows that the two valves are considered hydraulic valves operating in series and require the
monitoring that requires the type examination certification (EN81-20 § 5.6.7.3).
This monitoring must be carried out from the control panel or from a device that interfaces with it, checking
automatically and continuously, 2s after each stop of the car at floor, the closed state of VB and VRP through
contacts SE1 and SE2 which must both be closed to authorize the next call.
A3 Intervention
In the well there must be a system capable to detect the unintended movement of the car with open doors
both upward and downward and stop the car within the limits required by EN81-20 §5.6.7.5.

To identify the unintended movements of the car, a device complying with point 5.6.7 of the EN 81-
20 standard and verified in accordance with point 5.8.3 of the EN 81-50 standard must be used.
This circuit, if detects movement of the car with the doors not closed, outside the unlocking area, it
must prevent the control panel from sending any command to the solenoid valves and / or to the
motor / pump unit. The system must be reset only by authorized and properly trained personnel.
2.4.2 HOW THE SE1 AND SE2 ONTA TS WORK
The 3010 2CH A3 distributor is equipped with two contacts (SE1 and
SE2) to control the closing of the shutters:
- VRP, piloted by the VMD solenoid valve (SE1) and
- VB, piloted by the solenoid valve VMP 2CH or 2CH / S (SE2)
The closing and the opening of the contacts SE1 and SE2 is related to
the position of the VRP and VB cursors and to the excitation or non-
excitation of the VMD and VMP solenoid valves.
Their condition must comply with what is shown in the following
diagrams.
2.4.2.1 THE STATUS OF THE SE1 AND SE2 ONTA TS (2 H)

2.5.1 ONNE TION WITH 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 hose verifying it is thoroughly
tightened.
ATTENTION
Ensure that there is no dirty inside the tube. These impurities could damage the sealing of the piston
and of the distributor and inhibit the correct operation of the system.
2.5.2 ONNE TION 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 clampdown. 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.
ATTENTION
Ensure that there is no dirty inside the tube. These impurities could damage the sealing of the piston
and of the distributor and inhibit the correct operation of the system.
