DESCRIPTION OF TABLE
1 INTERLOCK AND I/O
TERMINALS
Input Terminals
kV Setpoint (0-10VDC)
0 to 10 VDC remote analog signal input that con-
trols applicator output from 0 to 100 kVDC when
high voltage is enabled. This input is active when
the MicroPak local/remote switch is in the remote
position. Otherwise control is from the kV adjust
knob on the front of the MicroPak. In either mode,
the kV setpoint can be viewed by pushing and
holding the View/Change Setpoint switch (see
Figure 8) on the front of the MicroPak.
Over-Current Setpoint
(0-10VDC)
0 to 10VDC remote analog signal input that sets the
over-current point between 0 and 85 μA when high
voltage is enabled. If the current goes above this
setpoint an over-current fault will occur. This input
is active when the MicroPak local/remote switch
is in the remote position and dipswitch SW3-1 on
the MicroPak process board (see Figure 6A) is set
to the ON position. The range of the over-current
setpoint in this mode is 0 to 3.30VDC equals 0 to
85 microamps. The microamps are limited to 85
for all voltages above 3.30VDC.
If the local/remote switch is in the remote position
and dipswitch SW3-1 is OFF, then potentiometer
R21 on the top of the MicroPak process board (see
Figure 6A) will control the over-current setpoint.
This mode is convenient if it is desired to supply an
analog input signal for the kV setpoint but not for the
over-current setpoint.
Finally, if the local/remote switch is in the local
position, the over-current setpoint is controlled by
the μA adjust knob on the front of the MicroPak.
In any of the modes, the over-current setpoint
can be viewed by pushing and holding the View/
Change Setpoint switch (see Figure 8) on the front
of the MicroPak.
High Voltage Reset (24VDC)
24VDC remote input signal that allows remote
reset of fault conditions. When a fault occurs, a
momentary supply of 24VDC to this terminal will
reset the fault. Faults can also be reset by moving
the kV ON/OFF toggle switch on the front of the
MicroPak to the OFF position and back to the ON
position. This input can also be used to remove
the MicroPak from ready mode.
High Voltage On (24VDC)
Remote input signal that enables high voltage.
When 24VDC is supplied to this terminal, high
voltage will be enabled. This input mode is active
in either local or remote mode when dipswitch
SW3-3 on the MicroPak process board (see Fig-
ure 6A) is set to the ON position and the Ready
input is active (the ready input is made active
by moving the High Voltage Enable Switch (see
Figure 8) to the ON position or by connecting the
remote Ready input (see Table 1) to ground). If
in local mode and dipswitch SW3-3 is set to the
OFF position, high voltage can only be triggered
by moving the kV ON/OFF toggle switch on the
front of the MicroPak to the ON position.

† Never set dipswitch SW3-3 to the OFF
position with the remote Ready input active
(connected to ground) or high voltage will be
on all the time (whenever AC power is on).
Ensure dipswitch SW3- 3 is ON whenever
the Remote Ready input is active.
