INTRODUCTION
1.1 Description of the XRB80HR
MONOBLOCKSeries
he XRB80HR (high reliability) Monoblock® X-ray
source is designed for OEM applications powering its
internal Bipolar X-ray tube up to 80kV at 100W.It is
a complete integrated system consisting of a high voltage
power supply (HVPS), filament supply, X-ray tube and oil
encapsulant which provides the required high voltage
insulation in one compact enclosure . The combination of
proprietary control system and protection circuitry.
Additional advantages are the elimination of high voltage
cables and low leakage X-ray radiation.
Power factor corrected input regulator is utilized to
improve overall reduction in harmonic emissions and
EMI. The output provides a regulated +390VDC to
downstream switching circuitry enabling optimal
performance and efficiency.
The XRB80HR MONOBLOCKSeries incorporates
remote programming, monitoring, and fault indicators
including interlock.
The X-ray source is a sealed unit containing a HVPS and
an X-ray tube. The insulating oil provides electrical
insulation for the high voltage sections of the power
supply and the X-ray tube in a sealed tank. The oil also
functions as a coolant to carry heat away from the tube.
Convection cooling augmented by customer provided
external fan is required. A bellows in the tank of the X-ray
source compensates for the expansion of the oil as the oil
temperature varies with operating conditions thereby
eliminating the need for bulky overflow tank.
The XRB80HR is available either with fan shaped
(standard) or (optional) cone shaped beam geometries.
Proprietary emission control circuitry provides excellent
regulation of X-ray tube current, along with outstanding
stability performance. The XRB80HR is designed for long
field life.

1.2 Operating Features
The XRB80HR MONOBLOCKSeries incorporates
several standard features designed to optimize user
satisfaction and safety.
INTERNAL FAULT PROTECTION: The
XRB80HR MONOBLOCKSeries continually
monitors internal circuits critical to the proper
operation of the power supply. In the event that one
of these circuits does not function correctly, the fault
detection circuit latches the appropriate fault on the
front cover display and turns off the output.
LED FAULT/STATUS INDICATORS:
Indicators are located on the cover of
Inverter/Control Assembly and are provided to give
the user complete indication of system operation and
fault conditions.
POWER OVERVOLTAGE (OV)
ARC FLT UNDERVOLTAGE (UV)
OVERTEMP (OT) OVER CURRENT (OC)
UNDER CURRENT (UC) X-RAY ON
OVER POWER (OP)
WATCHDOG OPERATION: The HVPS employs
an internal watchdog timer to discontinue X-ray
operation in instances where the host computer has
lost communication and control of the HVPS system
for a period greater than ten second. This feature is
enabled via RS-232 host command.
LOCAL MONITORS: provides Local analog
monitors for the output voltage and current via analog
voltage outputs on J2 on the front cover.
REMOTE PROGRAMMING: Allows remote
adjustment of the output voltage and current via RS-
232 digital interface port at J3 on the front cover. All
program values default to zero upon power up.
REMOTE MONITORS: Provides remote monitors
of the output voltage, output current and Filament
current via RS-232 digital interface port at J3 on the
front cover.
X-RAY ENABLE CONTROL: Provides control of
X-ray ON and X-ray OFF via RS-232 communication
or analog enable via J2-15 (connect to J2-13).
EXTERNAL INTERLOCK: The X-ray cannot be
enabled unless the external interlock is closed by
connecting J2-11 to J2-12. During high voltage
operation, opening the interlock circuit will cause the
High Voltage to be disabled. Interlock status
indication via RS-232 interface at J3.
IMPORTANT
This control signal is not a safety
interlock and should not be used for
protection from X-ray generation for
safety purposes.
HV ON LAMP RELAY: When X-ray ON command
is enabled a NO and a NC relay contact closure will
occur at connector J2. Refer to pin assignments
datasheet SHV#128118-001 and specification for
contact ratings.
OIL TEMPERATURE MONITOR: Provides
remote oil temperature monitor via RS-232 digital
interface port at J3 on front cover.
PS Fault Indication: PS Faults an open collector
output on J2-1, indicates that a faults has occurred.
High = no faults.
X-ray On Indication: X-ray On Signal is an open
collector output on J2-14, indicates that a faults has
occurred. High = X-ray off
XRB80PN100HR MONOBLOCK® MANUAL 4 118169-001 REV C
1.3 System Status and Fault
Diagnostic Display
If a fault occurs, the power supply will revert to the
POWER DOWN mode indicated by extinguishing of X-
ray ON led and via RS-232 as HV OFF. To reset a fault, a
clear command or X-ray ON command must be sent via
RS-232.
EXTERNAL INTERLOCK FAULT: Indicates that
the high voltage supply is inhibited by external
interlock protection circuitry solely via RS-232
communication as (ARG 8) Open Interlock.
OVERVOLTAGE: Indicates the over voltage
protection circuitry has caused the high voltage to
turn off. Over voltage protection is internally set to
88kv. This fault is indicated by OV led status on the
front cover and via RS-232 as (ARG 3), Over
Voltage.
OVER CURRENT FAULT: Indicates the output
current has exceeded 2.20ma or if the allowable
percentage of error between actual and programmed
emission currents is exceeded resulting in the HV to
be turned off. This fault is indicated by illumination
of OC led status on the front cover and via RS-232 as
(ARG 5) Over Current.
ARC FAULT: On the standard unit indicates that an
arc has occurred. This fault is indicated by
momentary (~ 1 sec) illumination of ARC FLT led
status on front cover and via RS-232 as (ARG 1) Arc.
Occurrences of four arcs with in a period of ten
seconds will shutdown the high voltage. This fault is
indicated by illumination of ARC FLT led status on
front cover and via RS-232 as (ARG 1) Arc.
UNDER VOLTAGE: Indicates a failure in the
voltage regulation circuitry. This fault occurs when
there is a lack of output power to maintain regulation
and will result in shutdown of the HV. This fault is
indicated by illumination of UV led status on the
front cover and via RS-232 as (ARG 4) Under
Voltage.
UNDER CURRENT: Indicates failure in the current
regulation circuitry. This fault occurs when the
allowable percentage of error between actual and
programmed emission currents is exceeded, due to
the actual emission current being less than the
programmed level. This fault does not shutdown the
HV, it is indicated by illumination of UC led status on
front cover and via RS-232 as (ARG 6) Under
Current.
OVER TEMPERATURE: Indicates that the internal
oil temperature has exceeded 66 deg C. This could be
either caused by a failure in the customer supplied
cooling fan that would cause the oil temperature to
exceed 65 deg C or the ambient temperature has
exceeded 40 deg C, resulting in shutdown of HV.
This fault is indicated by OT led status on the front
cover and via RS-232 as (ARG 6) Over Temperature.
POWER ON LED: When input power is applied to
the unit it is indicated by the POWER led being
illuminated.
X-ray On LED: when the high voltage status is
“On” state it is indicated by X-RAY ON led status on
the front cover.
WATCHDOG TIMER: Indicates the host computer
has lost communication and with the HVPS system
for a period greater than ten second. This feature is
enabled via RS-232 host command. This fault is
indicated via RS-232 as (ARG 5) Watchdog Time-
out. See digital manual for details.
OVER POWER FAULT:Indicates the output
power has exceeded 107watts. This fault is indicated
by the illumination of both the UC and OC led status
on the front cover an, OP fault via RS-232 as (ARG
9) Over Power.
