Smart 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

Bar Graph Graph
Bar Bar Graph
See Fig. 2, and Table 1 on page 10. 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 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

causes.
Hz Indicator Indicator
Hz 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.
