9040 Cascade Low Voltage Control Unit - Installation
> If the input resistance of the recording
device is less than 5 megohms, it will
affect the reading on the 9040 control unit
microampmeter.

The analog current output signal can be adjusted
such that 0 to 10 VDC represents 0 to 100
microamps or 0 to 200 microamps, by opening or
shorting jumper JP8 on the main PC board (see
Figure 4 for JP8 location). The board is factory
supplied with JP8 shorted (covering both
terminals) such that 0 to 10 VDC represents 0 to
200 microamps. To set the analog output current
so that 0 to 10 VDC represents 0 to 100
microamps open jumper JP8 (reposition so that it
covers only one terminal).
The wiring from the user supplied analog output
current recording device (with input resistance of
5 megohms or greater) can be connected directly
to outside terminal 2PL-8, or for installations
requiring conduit, connected to the inside terminal
2SOC-8 as described below. Connect common
of the recording device directly to earth ground.
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.

9040 Cascade control units for automatic
applicatorss are shipped with a combination Triple
Setpoint/Analog Input Interface Board installed.
When set for triple setpoint operation, three
discreet setpoints for high voltage output at the
spray applicator can be selected, using two 24
VDC input signals. When set for analog input
operation a 0 – 10 VDC or 4 – 20 mADC input
signal can be used to select continuous kV output
at the spray applicator from 0 to rated kV. With
either setting a PLC, robot, ext. can thus select
from different voltages to suit the spray application.

An analog current output signal is available from
the 9040 control unit at 2PL-8 (outside) or 2SOC-
8 (inside). This signal can be connected to a
recording device (strip chart recorder, data
acquisition unit, etc.) to monitor the output current
of the control unit over time. This signal should
be referenced to earth ground. The input
resistance of the recording device should be 5
megohms or greater.
3. Route the wire of the external recording device
through the External Wiring Grommet opening and
connect to the existing wiring for 2SOC-8.
4. Slide the chassis back in, secure the front panel
screws, replace the fuse, and plug the control unit
back in.
