Startup

4. With the spray gun aimed into the booth, trigger the control unit and test
the spray pattern. Adjust the flow rate and atomizing air pressures until
you obtain the desired pattern.
NOTE:
The following steps describe electrostatic voltage settings made on
a Versa-Spray II control unit that includes AFC controls. A Versa-Spray II
spray gun can be used with older Versa-Spray control units without AFC
controls, but only the kV mode will be available unless the optional current
limit kit is installed.
5. Turn the control unit kV/AFC switch to the on position. Push the kV/AFC
switch in to put the unit in kV mode or pull it out to put the unit in AFC
mode.
S
If the switch is set for the kV mode, rotate it fully clockwise for
maximum voltage.
S
If the switch is set for the AFC mode, rotate it to position 4. This
position represents approximately 40 microamps.
NOTE:
When a new spray gun is put into service, or a multiplier is
replaced, set the kV/AFC switch to the kV mode. Turn the switch to the
maximum setting, and record the
μ
A output with no parts in front of the
spray gun. Monitor the
μ
A output daily, under the same conditions. A
significant increase in
μ
A output indicates a probable short in the gun
resistor. A significant decrease indicates a failing resistor or voltage
multiplier.
6. Coat a part and adjust the kV output or AFC settings and air pressures
to achieve the desired results.
Shutdown
WARNING:
Turn off the electrostatic voltage and ground the gun electrode
before making adjustments to the spray gun or nozzle.
1. Turn off power to the master control unit or the IPS control unit. Ground
the gun electrode to discharge any residual voltage.
NOTE:
Voltage and air to the pump and spray gun will be turned on and off
when the master control unit is turned on and off. The IPS control unit
power switch, kV potentiometer, and air pressure regulators can be left on
after the initial air pressure and kV settings are made.
2. Perform the daily maintenance procedure.
For information on the operation of other system components, refer to their
respective manuals.
Maintenance
WARNING:
Turn off the electrostatic voltage and ground the gun electrode
before performing the following tasks. Failure to observe this warning could
result in a severe shock.
