Classic AFC Mode
See Figure 4-3. Use the AFC mode to set μ 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 μ A.
Select
μ
A, then press the + or − buttons to enter the desired

The longer a button is pressed the faster the units change.
The valid AFC range is 5 − 100 μ A.
Encore LT PE Mode
To configure the controller for the Encore PE system, set function number 3
(Electrostatic Control) to setting 2 (Encore PE).
When the controller function number 3 is set to PE, the electrostatic settings
will allow the user to control both KV and μ A (custom mode) and they will be
able to control the μ A setting to values less than 3.0 μ A in 0.1 μ A increments.
For example, the user can set the
μ
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.
Two modes of pump air control are available:
