Activating and Adjusting the Electrostatics
WARNING
The atomizing air (A2) must be on before turn-
ing on the turbine air (TA). Actuating the turbine
air without atomizing air flow could damage the gun
and may create hazardous operating conditions
and result in serious injury and property damage.
1. Complete all the checks under the Operating
Checklist on page 14.
2. Make sure the atomizing air (A2) is on, then turn
on the turbine/electrostatics air (TA).
3. The turbine air pressure should be adjusted to 30
psi (2.1 bar) at the gun manifold inlet when air is
flowing. The gun may be operated at a lower air
pressure, but some voltage loss could occur. Do
not exceed 40 psi (2.8 bar) air pressure as there is
no added benefit and turbine life could be reduced.
Use the chart below to set the proper pressure at
the turbine hose inlet . Do not exceed these recom-
mended pressures or turbine life will be reduced.
Air Hose
Dynamic Pressure at Air Hose
Length
Inlet Required for Full Voltage
15 ft (4.6 m)
32 to 38 psi (2.2 to 2.7 bar)
25 ft (7.6 m)
34 to 38 psi (2.4 to 2.7 bar)
50 ft (15.3 m)
36 to 40 psi (2.5 to 2.8 bar)
75 ft (22.9 m)
38 to 42 psi (2.4 to 2.9 bar)
100 (30.5 m)
40 to 44 psi (2.8 to 3.1 bar)
4. Check the gun electrostatics display module, if
used, to see the voltage and current output levels.
Operation
NOTE: The gun's normal high voltage reading is 60 to
70 kV. If a ball end high voltage measurement probe is
used, the gun voltage will rise to about 85 kV. This will
happen with all resistive electrostatic guns.
See Electrical Troubleshooting on page 25 to cor-
rect voltage problems.
Activating the KV Switch
Apply a minimum of 50 psi (3.5 bar) air pressure to the
KV switch air fitting (KV) to activate it and switch to the
lower voltage setting. The lower voltage setting is fac-
tory set to 60 kilovolts at zero microamperes. To
change this setting, see page 37.
The solenoid valve used to activate the KV switch
must bleed the air out of the line for the switch to draw
back to the higher voltage setting.
