DO NOT operate the Analog Input
Feature with the jumpers removed
from JP2 or JP3, or with the jumpers in
any other positions that those shown
on the PC board silkscreen.
6.
Connect the positive analog control input
(source) to TB1-6 and the negative analog input
(common or return) to TB1-7. Route the wiring
through the external wiring grommet on the rear
of the 9040 control unit.

DO NOT use the analog input board
as a method for turning high voltage ON
and OFF. The control unit has specific
inputs for this purpose (see “Pneumatic
Connections and External High Voltage
Control” in this section).
>
ALWAYS turn the control unit’s AC
Power ON/OFF switch to the OFF
position before flushing, cleaning, or
serving the applicator.
NOTE
>
To eliminate problems caused by
external noise, a twisted, shielded pair
should be used for the analog input con-
trol wiring. Connect the shield to ground
at the analog control source ONLY.
5.
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.
6.
Slide the chassis back into the cabinet,
secure the front panel screws, replace the fuse,
and plug the control unit in.
The Analog Input board is now ready for use. A
0-10 VDC or 4-20 mADC input signal will
produce an applicator output of 0 to rated kV.
NOTE
>
The input resistance of the Analog Input
Board feature is:
0-10 VDC Operation: 200 Kilohms
4-20 mADC Operation: 249 Ohms
