1.3 System Status and Fault
Diagnostic Display
If a fault occurs, the power supply will react as described
and the fault will be reported via RS-232 or Ethernet. To
reset a fault, a clear command must be sent via RS-232 or
Ethernet.
•
POWER ON LED:
When input power is applied to
the unit it is indicated by the POWER LED on the
control cover 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 control cover.
•
EXTERNAL INTERLOCK FAULT:
Indicates that
the high voltage supply is inhibited by external
interlock protection circuitry. This fault is reported
solely via RS-232 or Ethernet communication as
(ARG 9) Interlock.
•
OVER VOLTAGE:
Indicates the over voltage
protection circuitry has caused the high voltage power
supply to turn off. The over voltage protection is
internally set to turn off the high voltage to the X-ray
tube if the X-ray tube voltage is 10% greater than the
set point or at 10% greater than the maximum rated
voltage. This fault is indicated by OV LED on the
control cover and via RS-232 or Ethernet as (ARG 6),
High Voltage.
•
UNDER VOLTAGE:
Indicates the under voltage
protection circuitry has caused the high voltage power
supply to turn off. The under voltage protection is
internally set to turn off the high voltage to the X-ray
tube if the X-ray tube voltage is 10% less than the set
point. This fault is indicated by illumination of UV
LED on the control cover and via RS-232 or Ethernet
as (ARG 5) Low Voltage.
•
OVER CURRENT:
Indicates the over current
protection circuitry has caused the high voltage power
supply to turn off. The over current protection is
internally set to turn off the high voltage to the X-ray
tube if the X-ray tube emission current is 18% greater
than the set point or at 10% greater than the maximum
rated emission current. This fault is indicated by
illumination of OC LED status on the control cover
and via RS-232 or Ethernet as (ARG 3) High Current.
•
UNDER CURRENT:
Indicates the X-ray tube
emission current is less the setpoint. This fault occurs
when the emission current is 18% less than the
programmed emission current. This fault
does not
shutdown the high voltage power supply, it is
indicated by illumination of UC LED on the control
cover and via RS-232 or Ethernet as (ARG 4) Low
Current.
•
ARC FAULT
: Indicates that an arc has occurred.
When a single arc occurs, the event will be indicated
by illumination of the ARC LED on the control cover
and via RS-232 or Ethernet as (ARG 2) ARC. Both the
ARC LED and the digital flag will be reported for 30
seconds.
Occurrences of four arcs within a period of ten seconds
will turn off the high voltage. This fault is indicated by
illumination of ARC FLT LED on control cover and
via RS-232 or Ethernet as (ARG 2) Arc.
•
OVER TEMPERATURE:
Indicates the over
temperature protection circuitry has caused the high
voltage power supply to turn off. The over temperature
protection is internally set to turn off the high voltage
to the X-ray tube if the internal oil temperature has
exceeded 65 degrees C. This fault is indicated by the
OT LED status on the control cover and via RS-232 or
Ethernet as (ARG 1) Temperature.
•
TEMPERATURE WARNING:
Indicates the oil
temperature inside the Monoblock is greater than 58
degrees C. This fault
does not
shutdown the high
voltage power supply. The warning is indicated by
flashing the OT LED status on the control cover and
via RS-232 or Ethernet as (ARG 11) Temperature
Warning.
•
POWER LIMIT FAULT
: Indicates the output power
has exceeded maximum rated power of the
Monoblock® causing the high voltage power supply
to turn off. This fault is reported solely via RS-232 or
Ethernet communication as (ARG 8) Power.
•
WATCHDOG TIMER:
Indicates the host computer
has lost communication and with the Monoblock® for
a period greater than 3 seconds. This feature is enabled
on by default. This fault is reported solely via RS-232
or Ethernet communication as (ARG 7) Watchdog.
