FEATURES AND REQUIREMENTS
1.1
THE 3010 2CH 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 2CH 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.
