CONTROL UNIT
(CASCADE UNITS)
When the AC power is turned on, the unit will
display the PC board applicator type number on
the kV setpoint display and the software revision
level in the µA display for 2-3 seconds.

Changing the Setpoint at the
Applicator
To change the setpoint at the applicator, the ap-
plicator must NOT be triggered. By pushing the
kV button on the rear cover of the applicator, the
setpoint will change. If there are 2 green lights lit,
setpoint 1 is active. If 2 green lights and 2 yellow
lights are lit, setpoint 2 is active. If all lights are lit
(2 green lights, 2 yellow lights, and 2 red lights)
setpoint 3 is active.
kV to the applicator can be turned off by pressing
the applicator kV button in for 2-3 seconds. This
can be done whether the applicator is triggered
or not and is useful if the kV needs to be turned
off for spraying into recessed areas. When the
kV is disabled in this manner, the kV meter will
DO NOT
turn the applicator off using the
applicator button in place of interlocking with
a solvent supply for flushing. The applicator
must be interlocked with solvent supply such
that when the solvent is on to flush the appli-
cator, there is no kV at the applicator.

read zero, OFF will be displayed in the microamp
meter, and all kV setpoint indicator lights will be
disabled. Pressing the kV button in for another
2-3 seconds turns the kV to the applicator back on.
BASIC OPERATION
(CASCADE UNITS)
Triggering
High voltage is actuated by pulling the trigger
to start the flow of atomizing and fan control air
through the applicator. When the applicator is
triggered, a new switch in the applicator is ac-
tivated. The kV setpoint is displayed on the kV
display, the actual current draw on the µA display,
and the high voltage light illuminates. Under the
µA display is a bar graph meter that illuminates
according to the actual current draw.
