1. Ensure the AC power, safety ground, low voltage
cable, and interlock connections are made as
described in the “Installation” section of this manual.
2. Turn the high voltage adjustment knob fully
counter-clockwise.
3. Turn the AC Power ON/OFF switch (see Figure
2) to the ON position. When the AC power is on the
green CPU Indicator on the front of the discreet
I/O module will illuminate.
4. Turn the MicroPak ON/OFF switch to the ON
position. The kV and
μ
A displays will come on
along with the yellow MicroPak Power Indicator
located above the switch.
5. Momentarily push the High Voltage Enable
Switch to the ON position. Assuming dipswitch
SW3-3 is off, the red High Voltage On Indicator
should turn on.
6. Using the kV Adjust Knob set the kV output to
the desired value as displayed on the kV Meter.
Ensure the over-current setpoint is set above, or at
for current control, the maximum expected current,
or an overload fault will occur. The over-current
setpoint can be adjusted by turning the
μ
A Adjust
Knob with the View/Change Setpoint Switch held
in.
7. To turn high voltage off, momentarily move the
High Voltage Enable Switch to the OFF position.
8. When finished spraying, turn the AC Power ON/
OFF Switch (see Figure 2) to the OFF position to
prolong the life of the internal fan.
0 to 10VDC kV setpoint input. When in local mode,
the over-current setpoint is adjusted by using the
uA Adjust Knob. When in remote mode the over-
current setpoint is adjusted by potentiometer R21
if dipswitch SW3-1 is OFF, or by the remote 0 to
10VDC over-current setpoint input if dipswitch
SW3-1 is ON.
Feedback Fault Indicator
Feedback Fault Indicator
Feedback Fault Indicator
Feedback Fault Indicator
Feedback Fault Indicator
Glows yellow whenever a feedback fault occurs.
The feedback fault monitors the HV and current
feedback signals from the cascade for abnormal
signal levels. A feedback fault indicates a possible
open circuit between the controller and the cascade
located in the Evolver applicator. Check the low
voltage cable and its’ connections for the cause.
When high voltage is on, a feedback fault may also
indicate a defective cascade. If the Feedback
Fault Indicator comes on and flashes, this indicates
a board malfunction. In this case, the MicroPak
Control Unit should be removed from service and
sent back to ITW Ransburg for repair.

Determines whether the MicroPak Control Unit is
in local or remote mode. In local mode the kV and
over-current setpoints come from the front panel
kV and
μ
A Adjust Knobs, respectively. In remote
mode, the kV setpoint comes from the remote
analog 0-10VDC kV input and the current setpoint
comes from either R21 at the top of the MicroPak
process Board (see Figure 6A) or from the remote
analog 0-10VDC Over-Current Setpoint input,
depending on the setting of dipswitch SW3-1.
