ADJUSTMENT OF THE MAXIMUM PRESSURE VALVE ON THE PAM (VS 10)
To adjust the maximum pressure valve on the handpump (PAM):
1. Refer to the hydraulic circuit diagram of the distributor;
2. Close the shut-off valve (R/S). [the lever must be at 90 ° with
respect to the pipe directed to the piston]
3. Open the pressure gauge tap (6)
4. Use the hand pump (PAM) to increase the pressure.
5. Verify on the pressure gauge (MAN)
If the value matches the one required by the documentation supplied
with the system (2.3 times the maximum static pressure - EN81-
20 §5.9.3.9.2.3) go to point 11
If the value does not match the one required:
6. Loose and remove the protection cap of the safety valve adjustment screw (10)
7. Loose the locknut of the screw (10).
-
Tighten in the screw (10 CW) to increase the intervention pressure
-
Loose the screw (10 CCW) to decrease the intervention pressure
8. Using the hand pump (PAM), reach the required pressure value by verifying the value on the pressure
gauge (MAN).
9. Tighten the locknut of the screw (10).
10. Mount and tighten the protection cap of the safety valve adjustment screw (10)
11. Reduce the pressure on the pressure gauge (MAN) by pressing the VMD or the push-button (ML).
12. Close the pressure gauge tap (6). Open the shut-off valve (R/S).
Example:
If the static pressure at full load is 35 bar, the maximum pressure value is obtained as
follows: 35 x 2.3 = 80.5. For this example, the pressure gauge should indicate 80.5 bar.
3.2.9
REMOTE HAND PUMP FILLING
For correct and safe working of the remote hand pump please refer
to the following procedure:
1. Verify that:
-
the end of the suction pipe, on the power unit side (nylon), is
under the oil level;
-
the suction pipe fitting and the locknut are properly connected
and tightened.
2. Loose the air bleeder screw (S).
3. Use the hand pump until the oil start to get out the air bleeder (S
CCW).
4. Tighten the air bleeder screw (S CW).

EXAMINATIONS AND TESTS BEFORE PUTTING INTO SERVICE
3.3.1
RUPTURE VALVE (VC) [EN81-20 §6.3.8]
ATTENTION
Before performing this test for the first time, make sure that the rupture valve on the
cylinder is already calibrated or make its adjustment.
(see technical report of the system and instructions of the rupture valve)
VC 3006
/B /G
To perform the rupture valve test, follow the procedure below:
1. Move the car with nominal load evenly distributed to the higher floor and
wait for the car stop and the doors close;
2. When the car has stopped, loosen the lock nut on the screw/tap (5) and
close the screw/tap (5 CW) until mechanical stop.
3. Move (Call) the car at the lower floor. The rupture valve, during
downward, when the system reaches the intervention speed, must stop
the car and maintaining it stationary.
ATTENTION
If the car does not stop, it is necessary to check / change the adjustment of the rupture valve
following the instructions contained in its manual.
4. Checked that the rupture valve engages, completely loose the screw/tap (5) and tighten the lock nut;
5. Use the hand pump to unlock the rupture valve
