9040 Low Voltage Control Unit Kit- Installation
To utilize the Triple Setpoint Feature perform
the following (refer to Figures 5a and 5b):
1. Ensure the front panel fuse is removed, the
control unit is unplugged, and the ON/OFF
switch is in the OFF position.
2. Loosen the front panel screws and slide the
control unit chassis out.
3. Ensure JP2
point/analog input board are set to TSP ON
position as shown on PC board silkscreen.
4. Route the wiring through the External Wiring
Grommet and connect to the Triple Setpoint
Board as follows:
Robot or PLC Common
24 VDC Setpoint 1 Select
24 VDC Setpoint 2 Select
An interlock line with the control unit
>
power and overload signal is provided
across terminals TB1-4 and 5. This line
can be used to indicate that high
voltage is ready (control unit is on and
not in overload state) if desired.
5. Slide the chassis back into the cabinet,
secure the front panel screws, replace the fuse,
and plug the control unit in.
The Triple Setpoint Board is now ready for use.
Turning on the robot or PLC output connected
to TB1-1 will activate Setpoint 1, while turning
on the robot or PLC output connected to TB1-3
will activate Setpoint 2. The third setpoint is
determined by the setting of the control unit
High Voltage Adjust Knob when both robot or
PLC outputs are off.

NOTE
High voltage outputs selected by TB1-1 (Setpoint
1) and TB1-3 (Setpoint 2) can be adjusted by
tweaking potentiometers P1 and P2 on the Triple
Setpoint Board, respectively. Typically P1 is
factory set to provide approximately 50% of
maximum kV, while P2 is set to provide
approximately 75% of maximum kV.

Board should be positioned so that it
covers only one terminal (open) for
proper operation. Turn the control unit
power OFF before flushing, cleaning,
or servicing the applicator.
To utilize the Analog Input Feature perform the
following (refer to Figure 5b):
1. Ensure the control unit is OFF< unplugged from
the AC outlet, and the front panel fuse is removed.
2. Loosen the front panel screws and slide the
control unit chassis out.
3. Set JP2 jumpers on Triple Setpoint/Analog
Input Board to ANLG ON position as shown on
PC board silkscreen.
When JP2 is set to TSP ON position
>
and no 24 VDC triple setpoint inputs
are applied, high voltage control is from
the High Voltage Adjust Knob on the
front of the control unit.
4. Set JP3 jumpers on Triple Setpoint/Analog
Input board to desired input (0 to 10 VDC or 4
to 20 mADC) position, as shown on PC board
silkscreen.
