Ransburg Voltage Master 2 78789_LEPS5001 - Manual (Page 23)

AC REMOTE I/O
If required by the application, the following AC
remote I/O connections can be made. The wiring
for these connections should be supplied through
conduit to the REMOTE I/O (AC) opening in the
bottom left corner of the control panel.
High Voltage On
As shown in Table 2 and the schematic of Figure
5, an external momentary, normally open switch
or PLC contact can be wired from terminals TB2-3
to TB2-5 to initiate turn on of high voltage. The
switch or contact should be rated for at least 2
amps at 120 VAC.
High Voltage Off
As shown in Table 2 and the schematic of Figure
5, an external momentary, normally closed switch
or PLC contact can be wired from terminals TB2-
8A to TB2-10 to initiate turn off of high voltage.
The switch or contact should be rated for at least
2 amps at 120 VAC.
External Alarm
As shown in Table 2 and the schematic of Figure
5, an external alarm horn can be wired from termi-
nals TB2-15 to TB2-chassis. This external, user
supplied alarm must be rated for 120 VAC and
have an operating current of less than 0.5 amps.
DC PUMP I/O
In applications utilizing the Ransburg 9966 DC
Fluid Pump Drive Assembly, terminal TB2-20 (see
Table 2 and Figure 5) can be connected to the
controller of the DC Pump. In this manner, the DC
pump is activated whenever high voltage (CR2) is
on. Also, by supplying air to pressure switch PS2,
the high voltage can be disabled while keeping
the DC pump on. This allows for checking of flow
rates without high voltage. The wiring for the DC
pump should be supplied through conduit to the
DC PUMP I/O opening in the bottom left corner
of the control panel.
DC REMOTE I/O
If required by the application, the following DC
remote I/O connections can be made.
High Voltage Setpoint Analog Input
When the front panel kV Local/Remote switch is in
the Remote position and high voltage is enabled,
a 0 to 10 VDC or 4 to 20 mADC signal (see Table
4) on this input produces 0 to 100 kV output from
the power supply tank.
Current Overload Setpoint Analog
Input
When the front panel OL Local/Remote switch is
in the Remote position, a 0 to 10 VDC or 4 to 20
mADC signal (see Table 4) on this input produces
a 0 to 1500 microamp current overload setpoint.
Actual kV Analog Output
Output signal which varies proportionately from
0 to 10 VDC or 4 to 20 mA DC (see Table 4) as
power supply tank output voltage varies from 0
to 100 kVDC.
Actual Current Analog Output
Output signal which varies proportionately from
0 to 10 VDC or 4 to 20 mA DC (see Table 4) as
power supply tank output current varies from 0 to
2000 microamps DC.
For maximum noise immunity, all analog I/O wiring
should be run in cable having a foil shield with an
overall braided shield. The foil shield provides
100% shielding, while the braid provides a means
of making proper 360° shield terminations at the
cable to cabinet connection points. To make
analog control connections perform the following:
1. Remove the cable grommet hardware from the
connector housing(s) labeled REMOTE I/O (DC)
on the bottom of the control panel (see Figure
6). Two connectors are provided so 2 separate
cables can be used if the connections opposite to
the control panel are in different locations.
