1.2 Operating Features
The
XRBHR/XRBD
MONOBLOCK
Series
incorporates several standard features designed to optimize
user satisfaction and safety.
•
INTERNAL
FAULT
PROTECTION
:
The
XRBHR/XRBD 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 X-ray output.
•
LED FAULT/STATUS INDICATORS
:
Indicators are located on the cover of the Control
/Inverter Assembly and are
provided to give the user a
complete indication of system operation and fault
conditions.

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 Monoblock®
for a period greater than three seconds. This feature is
may be enabled or disabled via RS-232 or Ethernet
host command and will default to enable at system turn
on.
•
LOCAL MONITORS
: Provides local analog
monitors for the X-ray tube voltage and current via the
analog interface connector on the front cover of the
control assembly. Reference XRBHR data sheet
SHV#128132-001or XRBD data sheet SHV#128146-
001.
•
REMOTE PROGRAMMING
: Allows remote
adjustment of the output voltage and current via RS-
232 or Ethernet interface. All program values default
to zero at system turn on.
•
REMOTE MONITORS
: Provides remote monitors
such as output voltage, output current and operating
temperature via RS-232 or Ethernet interface. See the
Communication Interface document SHV#101501-
695 for a full description of features and commands.
•
EXTERNAL INTERLOCK:
The X-ray cannot be
enabled unless the 24VDC has been applied to pins 1
and 2 of the analog interface connector as outlined in
the XRBHR data sheet SHV#128132-001 or XRBD
data sheet SHV#128146-001. During high voltage
operation, opening the interlock circuit will cause the
high voltage to be disabled.
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 RELAY:
When X-ray ON is enabled a N.O.
and a N.C. relay contact closure will occur. Refer to
the XRBHR datasheet SHV#128132-001 or XRBD
data sheet SHV#128146-001 for pin assignments and
contact ratings.
•
OIL TEMPERATURE MONITOR:
Provides
remote oil temperature monitoring via RS-232 or
Ethernet interface.
•
FAULT SIGNAL:
The Fault Signal is an open
collector output that indicates that a fault has occurred.
The connection can be accessed at pin 7 of the analog
interface connector. High = no faults.
