Enable/Disable
Low Power Mode: Press the Enable/Disable button
for three seconds to put the controller to sleep. To
wake the controller press the button again.
External Trigger Mode: Guns are turned on and off
by an external signal. To turn off an a single gun,
press the Enable/Disable button on its controller.
The next trigger signal automatically turns the gun
back on.
Continuous Trigger Mode: In this mode, the
Enable/Disable buttons turn the guns on and off.
When the gun is triggered the Trigger LED
lights, and the actual kV/A outputs are displayed.
When not triggered the kV/A setpoints are displayed.
The two air flow displays always show the setpoints.
The Smart Flow LED lights when the
controller is configured for Smart Flow mode. Refer to
Powder Flow Setting for an explanation.
Press the +or −buttons to select the desired
setpoint. The longer a button is pressed the faster the
units change.
Electrostatic Settings
Select ChargerMode
Select Charge Modes and electrostatic setpoints are:
Re-Coat: 100 kV, 15 A
Metallics: 50 kV, 50 A
Deep Recesses: 100 kV, 60 A
The kV/A +or −buttons have no effect in Select
Charge Mode.
Re-Coat Metallics Recesses
The controller switches to STD or AFC mode if the
STD/AFC button is pressed.

Custom Electrostatic Mode
Custom Mode is the factory default mode. In Custom
mode, both kV and A can be adjusted
independently. Both the STD and AFC LEDs are lit
when this mode is configured.
Use the View button to toggle the display
between kV and uA.
SThe valid STD (kV) range is 0 or 25−100 kV.
SThe valid AFC (A) range is 5−100 A.
Classic Electrostatic Mode
Classic Mode is the optional electrostatic mode. In
Classic mode you can choose to control kV (STD)
output or A (AFC) output, but not both at the same
time. When using the AFC mode, you set a top limit
for current output. If the current output goes above
the limit, kV output is decreased to maintain the
current setting.
The controller must be configured to use this mode.
Refer to your system manual for configuration
settings.
Press the STD/AFC button to toggle between
STD and AFC mode.
Press the View button to toggle the display
between kV and A.
Valid ranges are the same as in Custom Mode.
Powder Flow Settings
Smart Flow Mode −This is the factory default mode.
In this mode, you set the Total Flow rate and the Flow
Air %. If you decrease the flow air %, the flow air
pressure decreases, but the atomizing air pressure
increases, so that the result is that the powder
velocity remains the same.
Classic Flow Mode −This is the traditional method
of setting powder flow and velocity, by setting flow
and atomizing air percentages separately and
balancing them manually for optimum results.
Press the +and −buttons to select the desired
setpoint. The longer a button is pressed the faster the
units change.
Smart Flow Mode
The Smart Flow LED lights when the
controller is configured for Smart Flow mode.
sets the powder flow rate (Flow Air %).
sets the powder velocity (Total Flow).
Setting values for both are 0−99%.
Set Total Flow first to obtain the desired pattern size
and penetration, then set Flow Air % for the desired
powder flow.
NOTE: If either Total Flow or Flow Air are set to 0%
then the controller cannot output any air when
triggered and no powder is pumped.
Classic Flow Mode
To use Classic Flow mode, the controller must be
configured for it. Refer to your system manual for
configuration settings.
sets the flow air pressure as a percentage
of maximum pressure.
sets the atomizing air pressure as a
percentage of maximum pressure.
Setting values for both are 0−99% of maximum air
pressure.

Controller Configuration
During power up or wake up from disable, press and
hold the +and −buttons on the kV/uA panel for 1
second. When the kV/A panel displays F −1 for
function 1 the controller is in configuration mode.
To change functions, press the Plus or Minus buttons
on the kV/A panel. To change function values press
the Plus or Minus buttons on the Flow Air panel. To
save your settings and exit Configuration Mode,
press the Enable/Disable button.

System Operation
NOTE: Allow powder in feed hoppers to fluidize for
several minutes before spraying powder.
1. Turn on controller power. Make sure all gun
controllers are enabled. The displays on the gun
controller interfaces should light.
2. Multi-Gun Controller: Turn the interlock keyswitch
to READY.
3. External Trigger Mode: Start the conveyor and
run parts through the booth. The guns should be
triggered automatically by your triggering device.
Continuous Trigger Mode: Start the conveyor,
then press the Enable/Disable buttons to start
spraying power.
4. Adjust each controller to achieve the desired
spray pattern, powder flow rate, and transfer
efficiency.
On Initial Startup: With the gun triggered, air set to
zero, and no parts in front of the gun, record the A
output for each gun in the system. Monitor the A
output daily, under the same conditions. A significant
increase in A output indicates a probable short in
the gun resistor. A significant decrease indicates a
resistor or voltage multiplier that requires service.
Interface Messages
Trigger LED flashing:
SA trigger signal is received but the gun controller
is disabled. Press the Enable/Disable button to
enable the controller.
SA trigger signal is received but the conveyor is off
or the controller is locked out, or both. Start the
conveyor and turn the keyswitch to READY.
Flow display toggles between the setpoint and CO:
Conveyor is off.
Total Air/Atomizing display toggles between the
setpoint and LO: Controller is locked out.
Conveyor OFF
Controller Locked
kV/mA display flashes: Spray gun is shorted. Refer
to Troubleshooting for more information.

Troubleshooting
Refer to your system manual for more troubleshooting procedures, resistance checks, and continuity checks.
Problem Possible Cause Corrective Action
1. Powder not charging,
kV/mA display blinking
Gun power supply shorted Check gun cable and power supply.
Refer to your system manual for
more information.
2. Uneven pattern, unsteady
or inadequate powder
flow
Blockage in spray gun, powder
feed hose, or pump
Check the feed hose and pump.
Nozzle, deflector, or electrode
assembly worn
Remove, clean, and replace as
necessary.
Low pump air pressure Increase pump air setpoints.
Low fluidizing air pressure Increase air pressure.
Damp powder Check powder supply.
3. Voids in powder pattern Worn nozzle or deflector Remove and replace if necessary.
Plugged electrode assembly or
powder path in gun
Remove and clean.
4. Low powder flow or
surging
Low supply air pressure Input air must be greater than 4.0 bar
(58 psi).
Pump throat worn Check and replace if necessary.
Pickup tube blocked Check and clean if necessary.
Fluidizing air not adjusted correctly Check and adjust.
Powder hose plugged, kinked, or
ID too small for length
Check hose. If longer than 20 ft, use
1/2 in. ID hose.
Regulator on controller manifold
plugged or malfunctioning
Remove tubing at controller and
check air flow. Replace regulator if
necessary.
5. Loss of wrap, poor
transfer efficency
Low electrostatic voltage Increase voltage setpoint.
Poor electrode connection Remove and clean. Check electrode
and gun power supply.
Poorly grounded parts Check part grounds. Resistance to
ground should be less than 1
meg-ohm.
6. Powder build up on
electrode
Insufficient air wash air Remove air wash connector from
rear panel. Check orifice for blockage
and clean if necessary.
7. No kV output from gun Damaged gun cable or gun power
supply
Check cable and power supply.
