3.3.2
RESTRICTOR/ONE-WAY RESTRICTOR (VC) [EN81-20 §6.3.9]
ATTENTION
If a restrictor is installed on the cylinder, before performing this test for the first time, make
sure that it is already calibrated or make its adjustment.
(see technical report of the system and instructions of the restrictor)
VC 3006
/D /R
The test procedure is the same as for the rupture valve.
An exception is point 3 in which, during the downward, the restrictor must not block the system but
limit its descent speed to the defined value.
3.3.3
PRESSURE TEST [EN81-20 §6.3.10]
This optional test assures you about the integrity of parts under pressure, including those which
cannot be visually checked.
To perform the test, follow the procedure below:
5. Open the shut-off valve (R/S) (position A).
6. Move the empty car to the highest floor and using the hand pump (PAM)
send the piston to the up stroke.
7. Open the pressure gauge tap (6)
8. Looking at the manometer (MAN), use the hand pump (PAM) until a pressure
equal to 200% of the maximum static pressure is reached.
9. Once the pressure is reached, observe the system for 5 minutes to verify if
there are pressure drop and leakage
(leakages up to 10 bar are considered acceptable).
10. At the end of the test, press the button above the VMD to return the piston to
normal stroke conditions and to reduce the system pressure.
11. Close the pressure gauge tap (6).
3.3.4
PROTECTION AGAINST UNINTENDED MOUVEMENT [EN81-20 §6.3.13]
ATTENTION
The 3010 distributor is able to control the unintended movement of the car. Perform these tests only
after carrying out the previous ones.
To check the correct behaviour of the devices against unintended movement, it is necessary to check that the
control panel and the system work in compliance with EN81-20 §5.6.7.
3.3.4.1
PRELIMINARY REQUIREMENTS
As required by the EN 81-20 standard, the following must be respected:
-
The system must be equipped with at least one switch device capable of detecting the unintended
movement of the car.
-
The control panel must not send commands to the distributor and to the motor/pump unit when the
system is located, with doors not closed, outside the door unlocking zone.
NOTE
Before proceeding, check on the manual of the electrical part the operations to be performed,
necessary to carrying out the test.
3.3.5
ENERGY STATUS ZERO
NOTE
Before any cleaning or maintenance intervention it is necessary to set the hydraulic power
unit at energy status zero, referring to the following procedure.
1. Move the car to the lower floor.
2. Turn the main switch to the 0 - OFF position
3. Press the red button for manual descent manoeuvre (ML), so as to
move the car to the lower extra-travel point (car resting on the shock
absorbers/buffers)
4. Close the shut-off valve (R/S) by moving the lever to the OFF position;
for safety and to avoid accidental opening, remove or lock the lever
5. Completely release the residual pressure by pressing the central part of
the VMD.
6. In addition, comply with all the safety requirements required by the laws
and regulations in force in the country where the power unit is installed.
