Setting the pump pressure
The pump working pressure is set at the pressure regulator. The pressure regulator can be secured
against unintended changes by pressing the control knob into a grid position. If you want to adjust the
knob again, first pull it out of the catch position. The set pump pressure can be read on the pressure
gauge. The maximum pump pressure in the
perfect
Melt
is reduced to max. 5.3 bar by the safety valve. If
you need a higher working pressure, please contact our technicians.
Automatic pressure release
Upon removal of the air supply to the hot glue system, a safety valve opens and pressure in the hydraulic
circuit is released.
When using this function, please note:
•
You need an input pressure to the system of at least 4 bar with a quick exhaust function upon
shutdown
•
The removal of the input pressure has to be conducted by the customer, such as by opening a
security door and then by switching the main air supply.
•
For maintenance tasks in hydraulics, inadvertent switching on of the air after removal of the input
pressure has to be prevented; please follow the instructions in the machine manual for this
purpose. It is also urgently necessary to activate the manual pressure relief devices (chapter->
Bleeding the system). Of course, the safety instructions regarding adhesives are to be observed
(PSA, among others).
Attention!
The pressure relief function has to be checked regularly,
depending on your operating conditions!
