DESCRIPTION
5.1
COMPONENTS
VM 500
B_07020
The VM 500 control unit, together with the matching GM 5000EA or GM 5000EAC spray gun
and other components, form an electrostatic manual spray system.
5.2
MODE OF OPERATION
The VM 500 control unit supplies the control voltage for the spray gun, in which high
voltage is subsequently produced. The high-voltage supply is switched on and off via the
trigger of the spray gun.
The special linear characteristic for high voltage ensures that, if the spray gun is brought
too close to the work piece (or ground), the high voltage is reduced automatically to
prevent an accidental spark discharge.
The VM 500 control unit also offers a fault display.
5.3
PROTECTIVE AND MONITORING EQUIPMENT
The following functions are provided for safety:
– Electrical monitoring of high voltage and spray current (maximum ignition energy 0.24 mJ)
No ignition danger and no danger to personnel.
– Electrical ground monitoring of the spray gun.
