Purge Mode - Graco ProBell Electrostatic Controller Instructions And Parts

Operation Modes and Timing Diagrams

Purge Mode

During Purge mode flush solvent is present,
electrostatics are disabled, and the applicator is not
in motion.
To avoid fire, explosion, and electric shock, always
turn the electrostatics off when flushing, cleaning,
or servicing equipment. Always ground equipment
and waste container.
This can be accomplished by using one of
the interlock inputs or through control of the
Electrostatic Enable pin. This can also be
accomplished by powering down the controller.

Disable the electrostatics any time the solvent supply
is activated. Before enabling electrostatics again,
ensure that the paint and dump lines are completely
free of solvent. Determine any time and volume
requirements for paint to be loaded. Ensure that
the electrostatics are disabled for the entire load
sequence.
Deactivate the electrostatics using one or
combination of the following signals:
• System Power Interlock: Low
• 24 VDC Interlock: Low
• Electrostatic Enable Input: Low
• Powering off the Electrostatic Controller by
pressing the off button.
