Chapter 1

INTRODUCTION

1.1 Description of the XRB80HR
MONOBLOCK Series

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 MONOBLOCK Series 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 MONOBLOCK Series incorporates
several standard features designed to optimize user
satisfaction and safety.

 INTERNAL FAULT PROTECTION: The

XRB80HR MONOBLOCK Series 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 X­ray 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.
