DF3/FF3 MANUAL 3 118018-001 Rev E
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 1.5 for optional configurations.
DUAL FILAMENT SUPPLY INTERFACE:
An optional dual filament power supply is
available. This chassis interfaces to the FF3
power supply. Consult Spellman’s Sales
Department for details.
1.4.2 SYSTEM STATUS AND
FAULT DIAGNOSTIC
DISPLAY
LED front panel indicators are provided to give
the user indication of system operation and fault
conditions. If a fault occurs, the power supply
will shut down. To reset, toggle the CONTROL
POWER ON switch, or use the reset function .
INTERLOCK CLOSED: Indicates the
EXTERNAL INTERLOCK connections are in
the closed position.
INTERLOCK OPEN: Indicates the
EXTERNAL INTERLOCK connections are in
the open position.
OVER VOLTAGE: Indicates the over voltage
protection circuitry has caused the power
supply to turn off. Over voltage is internally set to
105%-110% of rated output voltage.
OVER CURRENT: Indicates the output current
has exceeded 110% of rated output current. The
over current level is internally set.
OVER POWER: indicates the output power has
exceeded the front panel or remote programmed
power trip level.
ARC: Indicates that a tube arc has occurred.
KV RGLT ERROR: Indicates that the high
voltage regulation circuit cannot maintain voltage
regulation. This may occur if the input voltage is
too low.
MA RGLT ERROR: Indicates that the tube
emission current regulation circuit cannot
maintain current regulation. This may occur when
tube filament problems exist.
FILAMENT CURRENT LIMIT: Indicates that
filament current has exceeded the programmed
filament current limit trip level.
KV MIN: Indicates the minimum KV level is not
being programmed. This indicator will illuminate
for approximately 10 seconds before shut down.
This provides protection of the tube filament. The
KV min circuitry also resets the KV and
MA/filament ramp circuits. When the voltage is
programmed higher than the kV min level, the
outputs will begin the ramp cycle.
LEAKAGE LIMIT/TEMP : On the FF3 power
supply, a tube leakage current detection circuit is
provided. Shut down will occur if leakage current
exceeds 10mA. A test point on the rear panel is
also provided for test purposes.
OPEN FILAMENT: Indicates the X-ray tube
filament or connections to the filament are open.
1.5 OPTIONS:
The options available are listed in Table 1.1. See
Section 5 for more information on these options
along with operating and set-up instructions. With
few exceptions, these options can be retrofitted to
your power supply at the factory in a short time.
For price and retrofit arrangements, contact the
Spellman Sales Department.
