lamps are defective and should be
replaced in order to generate high
voltage. Control power and X-ray off
lamps are also dual type lamps for
added reliability. This should go out, or
appear in a different form.
INTERNAL FAULT PROTECTION
AND DIAGNOSTICS:
The DF/FF
series continually monitors internal
circuits critical to the proper operation
of the power supply and X-ray tube.
The diagnostic programming is a
software based, decision-making
technology. Flexible software provides
very sophisticated decision-making
capabilities within the power supply.
Also, a variety of user configurations
can be achieved by custom software
written by Spellman Engineering. If a
specific fault condition or diagnostic is
required, consult Spellman High
Voltage Engineering Department.
1.2.1 REMOTE OPERATING
FEATURES
REMOTE PROGRAMMING:
Allows remote adjustment of the output
voltage, output current, filament current
limit, and maximum tube power via an
external voltage source.
REMOTE MONITOR: Allows
remote monitoring of the output voltage
and output current.
REMOTE X-RAY ON/OFF
CONTROL:
Allows remote control of
X-ray ON and X-ray OFF functions.
Signals are also provided for remote
indication of X-ray ON status. This can
be used for a variety of water control or
remote lamp functions.
REMOTE POWER ON: Allows
remote control of Control Power
ON/OFF function. This feature also
allows remote reset of the power supply
in case of a fault shutdown.
EXTERNAL INTERLOCK: Interlock
connections are provided for a variety of
water flow and safety functions. The unit
will not operate unless the interlock is
closed. Opening the interlock circuit will
cause the unit to shut off.
REMOTE STATUS SIGNALS: A
variety of power supply status signals are
available on the remote interface. These
signals are open collector type. Over
current, over voltage, filament limit,
overpower, and power supply fault status
signals are available from the remote
interface. Other signals can be supplied as
required.
REMOTE FAIL-SAFE INDICATOR
LAMP:
A remote signal is available for
connection to an external X-ray ON
indicator lamp. This circuit senses proper
operation of the external lamp and will
shut down high voltage if the lamp is
open. 12V-24Vdc or 220Vac lamps can
be accommodated. 24Vdc is standard,
other voltages may be specified when
ordering.
REMOTE WATER SOLENOID
CONTROL SIGNAL:
A signal is
provided for energizing a remote water
solenoid for X-ray tube water flow
requirements. This signal can be provided
when the control power is energized of
when X-ray ON is energized. 24Vdc
energized with X-ray ON is standard,
220Vac switched is also provided. See
1.3 for optional configurations.
DUAL FILAMENT SUPPLY
INTERFACE:
An optional dual filament
power supply is available. This chassis
interfaces to the DFFF power supply.
