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 Electrical Troubleshooting, page 37 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.
Gun Overview
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 Adjusting the Low Voltage Setting, page 10.
NOTE: If the Error display appears, the Smart module has lost communication with the power supply. See Error Display, page 10, for further information.
