CHAPTER 6 - Use and Operation
6.8
USE OF THE MECHANICAL OR ELECTRICAL SLOW CLOSING INLET VALVE (OPTIONAL FEATURE)
The following instructions need to be applied prior to pressurising the water in the machine.
When the machine is equipped with a mechanical valve.
Ensure the ball valve is OPEN and to do so just ensure the rod of lever L is completely moved to the left as shown in the picture below.
OPEN CLOSED
L
When the machine is fi tted with electric valve:
Ensure the water valve opens after turning on the computer and pressing the + key on the keyboard as required by the program displayed on the
monitor and if needed, manually operate the suitable lever.
If the above conditions are met and the hose is unwound, the system delivering water to the machine may be pressurised.
CAUTION
If the machine is equipped with slow closing inlet valve, the pumping station must be equipped with an automatic stop. In the
event it is not, the pumping station must be stopped intentionally and in due time in order to prevent hazardous situations due
to excessive pressure in the machine's water inlet pipes and/or downstream of the station.
6.8.1
ADJUSTMENT OF SLOW CLOSING INLET VALVE
When the machine is fi tted with mechanical valve, no adjustment is required.
When the machine is equipped with an electrical valve, the parameter set on the computer must be adjusted to change its closing time, the computer
Manual must therefore be referred to.
6.8.2
OPERATION TO BE PERFORMED ON THE MACHINE PRIOR TO MOVING IT, IF IT IS EQUIPPED WITH SLOW
CLOSING INLET VALVE
When the machine has completed work and in any case where it should be required to interrupt work for any need to move it, the following operations
must be performed:
NOTE
Prior to disconnecting the pipes delivering water to the machine and/or to moving the machine, it is essential to ensure the
pumping station has automatically switched off at the end of work or has been intentionally shut off to interrupt operation.
Consequently, the valve in question must have either automatically shut off or been shut off by the operator and the water
delivery pipe is still pressurised.
1) Close the valve upstream of the piping (pumping station) conveying water to the machine.
2) For the mechanical valve manually move lever L in OPEN valve position so the internal pressure is cleared.
For the computer controlled electrical valve, perform the OPENING operation using the computer keyboard so the internal pressure is cleared.
3) When the pressure has run out, disconnect the hose delivering water to the machine and proceed with its preparation for moving.
6.9
USE OF THE MECHANICAL OR ELECTRICAL DISCHARGE VALVE (OPTIONAL FEATURE)
When the machine is equipped with a mechanical discharge valve, the following steps must be followed:
1) Start up the machine.
2) Ensure the water valve is OPENED by the 3-way cock controlling it when the stroke end stop is simulated (see item 6.par. 6.2.2.2).
When the machine is equipped with a computer controlled discharge valve, the following steps must be followed:
1) Turn the computer on and press the + key on the keyboard as required by the program that is displayed on the monitor and ensure the solenoid
valve has received the impulse to CLOSE the water valve.
2) Ensure the valve is OPENED by the impulse received by the solenoid valve when the stroke end stop is simulated either by acting on the corrector
or pressing the STOP key on the computer keyboard. (see item 6.par. 6.2.2.2).
DANGER
When the discharge valve opens, water
fl ows out suddenly and forcefully. Do not stand in the immediate vicinity of the outlet
hose.
If the machine is positioned near a road or work place, ensure the water expelled by the discharge valve does not reach persons
or transit areas.
To prevent this hazard, a rubber hose must be connected to the discharge valve outlet fi tting, so the water fl ows to the ground
without creating any hazardous situations.
