SW3-3 on the MicroPak process board (see Figure
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.

Ready
Remote input used to put the MicroPak Control
Unit in ready mode. This input is made active by a
momentary ground connection. Once active, it
can only be deactivated by activating the remote
High Voltage Reset input or by momentarily moving
the High Voltage Enable switch (see Figure 8) to
the OFF position. This input must be made active
(grounded) before high voltage can be enabled
using the remote High Voltage On input. This can
be done externally or by hardwiring this input to the
P3-A2 ground connection for MicroPak #1 or the
P3-A6 ground connection for MicroPak #2. When
hardwired to ground, the MicroPak will be in HV
ready mode whenever there are no faults present
and the High Voltage Reset Input is not active.

Each 24VDC output is supplied through a relay
contact capable of handling up to 1 amp of current.
However, if one or more outputs are active at the
same time, the total output current should not
exceed 2 amps.

Interlock Terminal
Terminal that allows interlocking of high voltage
with safety components. In order to obtain high
voltage, the interlock terminal for the respective
MicroPak control unit must be connected to ground
by a jumper or voltage free contact. If the high
voltage is enabled without the interlock terminal
being connected to ground, high voltage output will
not occur. This terminal is a convenient place to
interlock the controller with the exhaust fan and
conveyor as required by NFPA-33. If the interlock
connection is momentarily lost, the connection
must be restored and the high voltage re-enabled
before the high voltage output will turn back on.
