Classic Electrostatic Mode (contd)
Figure 4-3 kV/ A Display and STD/AFC Selection for Classic Mode
Classic AFC Mode
See Figure 4-3. Use the AFC mode to set A output limits. In AFC mode kV
automatically defaults to 100 kV. When current output increases, kV output
and electrostatic charging decreases. The closer the gun comes to the part,
the greater the current draw.
1. Press the STD/AFC button to toggle between STD and AFC. The AFC
LED lights when AFC is selected.
2. Press the View button
to toggle the display between kV and A.
Select A, then press the + or − buttons to select the desired A
setpoint. The longer a button is pressed the faster the units change.
The valid AFC range is 5−100 A.
Encore Nano Feedback Control Mode (NFC)
To configure the controller for the Encore NFC system, set function number
3 (Electrostatic Control) to setting 2 (Encore NFC).
When the controller function number 3 is set to NFC, the electrostatic
settings will allow the user to control both KV and A (custom mode) and
they will be able to control the A setting to values less than 3.0A in 0.1A
increments.
For example, the user can set the A settings from 5, 4, 3.0, 2.9, 2.8, .....
through 0.1.
Powder Flow Settings
The controller varies the flow and atomizing air to a venturi-type powder
pump depending on the settings. Flow air controls the amount and velocity
of the powder; atomizing air dilutes the powder flow and increases the
velocity. Since the air flow values are continuously monitored and adjusted,
a slight high frequency pulsation in the air lines is normal.
