MicroPak - Operation
Ransburg
13 LN-9218-00.13
OPERATOR CONTROL
Operator control may be accomplished by:
(1) front panel controls
(2) CANBus serial communication
(3) node adapter
(4) discrete analog and digital I/O
1. Front panel controls are provided for power on,
high voltage set point, over current set point, di/
dt sensitivity, and high voltage on/off.
2. CANBus connection provides expanded
control and monitor functions shown as analog
in/out and discrete in/out in the MicroPak Spec-
ifications.
3. Node Adapter connection converts an external
serial protocol, such as Allen-Bradley Remote I/O,
to CANBus for communication to the MicroPak.
The format for Allen-Bradley communication is
shown under “MicroPak Node Adapter PLC I/O”
in the “Operation” section of this manual.
4. Discrete I/O connections are made via the
76111-xx I/O cable which connects to connector
J12. The 76111 connector must be secured to
the J12 connector shroud by the two screws on
the connector body. The pin-out of the discrete
signals begins on page 14.
The Discrete I/O Module switch SW2, position 1
must be set for the cascade in use with the Mi-
croPak. For RP1000 or LEPS5002 application,
SW2-1 is OFF. For HP404, RP404 and HP505
application, SW2-1 is ON.
OPERATION
MODES OF OPERATION /
CONFIGURATION
(Refer to Figure 6)
Local / Remote
The Local/Remote switch located on the front panel
determines the source for the setpoints for kV, di/
dt and Over Current. In the Local Position, these
come from the front panel controls labeled kV and
µA. In the Remote position, these come from the
Node Adapter, directly from CANBus, or from the
Discrete I/O Module, except as described below.
The MicroPak can be configured for a fixed (in-
ternal adjustment) µA (overload) setpoint while
accepting a remote analog kV setpoint. To enable
this feature, see figure 6. In this configuration,
the µA setpoint comes from pot R21 at the top of
the Process PCB instead of the external analog
signal. Holding in the “SET” button will display
the analog kV setpoint and the fixed (internal) µA
setpoint.
HV Cascade / Regulation Mode
The MicroPak is factory configured for HP404,
RP404, or HP505 cascade applications or ap-
plications using the 74793-XX or LEPS5002 HV
units. In addition, the cascades may be operated
in voltage regulation or current regulation modes.
Each configuration has a specific part number as
shown in the “Parts Identification” section of this
manual.
HV On Control Remote
When remote HV On controls are used, SW3-3
should be set to ON. Motherboard terminal J6-3
should be jumpered to J6-2 to enable the HV
Ready mode.
