Valve (10) One Roller Load.
This valve is powered during loading, it diverts the oil to tank between the two
rollers so that for loading only the drive roller rotates.
Valve (11) Wrap Arm Unfold.
This valve unfolds the wrapping arm to the straight position.
Valve (15) Roller Stop.
This valve stops the rollers turning during an automatic wrapping sequence.
It is pulsed on and off to reduce the roller speed when the film break sensors detect
that one film has broken. It can be manually operated by pushing button R4 during wrapping.
Valves 16,17,18 are on the tower block
Valve (16) (VBS) Brake valve.
This is a pilot operated (8:1 Ratio) load holding valve. It makes the wrap arm run smoother
in hilly conditions and holds the wrap arm in place when parked.
Valve (17)(VMP) Cross Line Relief Valve Forward
This valve limits the max. torque of the wrapping arm. If the inlet pressure exceeds the set value, it relieves the oil across to the outlet side of the motor. It is adjusted
so that the pull force on the far end of the arm is approx. 35 KG. If it is set too high acceleration at the beginning of wrapping will be very sharp.
Valve (18)(VMT) Cross Line Relief Valve Reverse
This valve ensures a gradual stop for the wrap arm by limiting the pressure on the outlet side of the motor. If the pressure exceeds the set value, it relieves the oil across to the inlet side of
the motor.
Valve(19) Main Relief Valve
The hydraulic system is equipped with a safety relief valve, which is preset to 185 bar. If this pressure is exceeded it opens and allow the oil from the pressure port to the tank port of con-
trol valve.
IMPORTANT:
Valves 16 to 19 have been carefully set in the factory. Incorrect adjustment of these may cause damage to the machine. Always ensure that trained personnel only adjust the settings of
these valves.
