Description
The VantagerManual Spray Gun Control Unit
provides pneumatic and electrostatic controls for
Nordson Econo-Coatr, N80, Vantage, and
Tribomaticrmanual spray guns. The control unit
provides the voltage output to the spray gun and
monitors the feedback current to control the
electrostatic charging of the coating material.
Three versions of the control unit are available
including a standard unit and 115V and 220V units
with vibratory motor control.
The vibratory motor control turns the vibrating
motor on whenever the spray gun is triggered and
remains running for approximately 30 seconds after
the spray gun is triggered off.
Operating Modes
The Vantage Manual Spray Gun Control Unit has
two operating modes:
kV: Operator may adjust the voltage output
AFC: Operator may adjust the maximum current
(μA) output
KV
AFC This key toggles between the two operating
modes. LEDs above the key indicate which mode
is currently active.
NOTE: When the controller is configured for use
with a Tribomatic spray gun, the display shows the
current feedback from the spray gun.
Specifications
NOTE: Because of continuous technological
improvements, specifications are subject to change
without notice.
