XRBHR/XRBD SERIES MONOBLOCK® MANUAL
8
118185-001 REV B
BEFORE CONNECTING THE MONOBLOCK® TO
THE AC LINE, FOLLOW THIS PROCEDURE.
1) PROPER GROUNDING TECHNIQUES:
The
Monoblock® must be grounded, by making a ground
connection to the M5 threaded hole on the tank flange. The
control assembly must also be grounded using the M5
ground stud located on the cover of the control assembly.
Note:
For optimal EMC results the Tank and Controller
should be mounted to the same ground plane, if not a
ground wire (preferably a braided wire) should be
connected between the tank and the controller.
2)
Connect the control cable to the Monoblock® and secure
the cable ground to the Monoblock® using the M5
threaded hole on the tank flange.
3) ENSURE THAT THE EXIT PORT IS PROPERLY
MATED
TO
THE
COLLIMATOR
OR
SATISFACTORILY SHIELDED WITH LEAD PLUG
TO LIMIT EXPOSURE TO LEAKAGE RADIATION.
X-ray Safety Procedures must be followed when
testing this unit. The XRBHR/XRBD is capable of
producing Lethal Voltages and X-ray Radiation.
Only proceed with operation of the HVPS after
a) consulting with the Manufacturer and
verification of X-ray setup for the proper
precautions.
b) reading this entire document.
NEVER OPERATE THIS UNIT WITH AN OPEN
X-RAY EXIT PORT.
It is recommended not to allow leakage radiation
exceeding 0.5mR/hr at 5cm from any surface of
the XRBHR/XRBD MONOBLOCK
.
3.2 Signal and Power Interface
Connections
1)
Connect Ground wires as suggested above.
2)
Connect digital signal interface RS-232 or Ethernet
communication cable from the host computer to the
connector on Control Assembly.
3)
Connect 90 - 264VAC line to the AC input connector.
Reference power and interface connections located on the
XRBHR data sheet SHV#128132-001 or XRBD data sheet
SHV#128146-001. Make sure AC line voltage is OFF
when connecting to the unit.
4)
Connect 24VDC to pins 1 and 2 of the heat dissipation
unit. It is critical that power is supplied to the heat
dissipation unit to ensure proper operation of the
Monoblock. Reference DC input for heat dissipation unit
located on the XRBHR data sheet SHV#128132-001 or
XRBD data sheet SHV#128146-001.
5)
Apply the 24VDC external Interlock by connecting
24VDC to pins 1 and 2 of the analog interface connector.
Reference analog interface located on the XRBHR data
sheet
SHV#128132-001
or
XRBD
data
sheet
SHV#128146-001.
6)
Determine unit’s idle time and refer to Appendix A for
the recommended seasoning schedule. Also reference
paragraph 4.5.21 and 4.5.28 of the Communications
Interface document SHV#101501-695.
3.3
Analog monitors
1) The X-ray tube voltage can be monitored by measuring
the voltage at pins 4 and 5 of the analog interface
connector. Reference analog interface located on the
XRBHR data sheet SHV#128132-001 or XRBD data sheet
SHV#128146-001.
2) The emission current can be monitored by measuring the
voltage at pins 6 and 5 of the analog interface connector.
Reference analog interface located on the XRBHR data
sheet
SHV#128132-001
or
XRBD
data
sheet
SHV#128146-001.
3.4
Digital control
G.U.I and operation instruction
1) Install the G.U.I software to the host computer (See CD
with GUI).
2) Start the G.U.I.
3) Read agreement then click AGREE.
4) Operate the unit using the GUI. For instruction on GUI
operation, see the “Monoblock® X User Manual.
3.5 X-ray Tube Seasoning Process
Caution
: To prevent premature degradation of the X-ray
tube, it is highly recommended to season the X-ray tube if
the unit has been idle for greater than 24 hours. Please refer
to Appendix A for the recommended seasoning schedule.
Also reference paragraph 4.5.21 and 4.5.28 of the
Communications Interface document SHV#101501-695.
