MELTER OPERATION
Adjusting the manual valve
Follow the steps below to set the pressure using this type of valve
(approximate):
1. Screw the spindle in as far as possible in the clockwise direction. In
this position, the maximum pressure is 81,5 kg/cm
2
(80 bar).
2. Gradually loosen anti-clockwise until the desired pressure is reached.
Each millimetre the spindle sticks out corresponds -approximately- to
a reduction of 9 kg/cm
2
(8,82 bar).
By default, the equipment is calibrated with a hydraulic pressure of
approximately 40 bar.
Pneumatic valve control
To adjust the pressure with this valve model, follow these steps:
1. Unlock the pressure regulator control by pulling on it gently.
2. Turn it clockwise to increase the pressure. This will be seen reflected
on the pressure gauge located next to it.
Warning: Do not exceed 6 bar of pressure. This corresponds to 80 bar on the
hydraulic circuit.
Turning off the melter
If it is necessary to disconnect the melter:
1. Press the control card ON/OFF button to switch off the card.
2. Disconnect the equipment’s power switch located on the side, next to
the power supply input.
3. Disconnect the applicators’ pneumatic power supply and the electric
supply to the control programmer if applicable.
