Gun Overview

Smart Guns

The Smart Gun module displays spraying voltage,

current, alternator speed, and the voltage setting (low

or high). It also allows the user to change to a lower

spraying voltage. The module has two modes:
• Operating Mode
• Diagnostic Mode

Operating Mode

Bar Graph

See Fig. 2, and Table 1 on page 11. The Operating

Mode displays gun data during normal spraying. The

display uses a bar graph to show the voltage level in

kiloVolts (kV) and the current level in microAmperes

(uA). The bar graph range is from 0 to 100% for each

value.
If the uA bar graph LEDs are blue, the gun is ready

to spray. If the LEDs are yellow or red, the current is

too high. The ﬂuid may be too conductive, or see

for other possible

causes.

Hz Indicator

The Hz indicator functions the same as the ES

indicator on standard guns. The indicator lights to

show the alternator speed status, and has three

colors:
• Green indicates the alternator speed is correct.
• If the indicator changes to amber after 1 second,

increase the air pressure.

• If the indicator changes to red after 1 second,

reduce the air pressure.

Voltage Adjustment Switch

The voltage adjustment switch (VA) allows the

operator to change from low to high voltage.
• The high voltage setting is determined by the

maximum voltage of the gun and is not adjustable.

• The low voltage indicator (LO) lights

when the switch is set to LO. The low

voltage setting is user adjustable. See

NOTE: If the Error display appears, the Smart module

has lost communication with the power supply. See

, for further information.
