MA-5162-ENG PISTON ADHESIVE MELTER INSTALLATION
3-5
Pneumatic connection
Before connecting the pneumatic power to the melter/applicator, make
sure the pressure regulator is completely closed. To do this, turn the
regulator located on the front of the equipment next to the pressure gauge
counterclockwise as far as it will go.
Connect the plant air supply (max. 6 bar) to the melter/applicator intake using
flexible tubing with an outside diameter of 8 mm. The equipment is provided
with a quick coupling for this purpose.
Activate the air supply to pass and turn the pressure regulator clockwise.
Adjusting to 1 bar of pressure is enough for checking the pump operation.
The pump will not operate and the pressure gauge will show 0 bar until the
melter/applicator and the hoses-applicators connected to it reach the correct
temperature.
Once the pump operation has been checked, you may adjust the pressure to
the operational value you wish.
In the pressure gauge can be found pneumatic and hydraulic pressure values,
the relation between both are 1:13.6.
Warning: Do not exceed a pneumatic pressure of 6 bars under any
circumstances. This may cause severe damage to the unit. Risk of projection
of high-speed particles which may cause significant injury.
(1) The maximum permissible current for a connection is 27 A per phase. The table show the
maximum current when using the maximum possible power. Calculate the power to be installed in
each case to choose a suitable connection.
