Before continuing, note the phase-shift capacitor value is compatible with your X-ray tube stator. Please
refer to table 1, in the supplement,
X-ray Tube Start Compatibility Tables
in this manual. If the value of
the phase-shift capacitor is
not
compatible with the desired X-ray tube stator type, please contact CPI
product support for assistance.
Confirm that the boost voltage is set correctly for the selected tube type per the referenced Table 1 before
continuing. The procedure for setting the boost voltage is detailed in 2.7.1. The boost voltage may be
measured from F6 to F7 on the H.V. auxiliary board.
If the desired tube type is not listed, please contact CPI product support for assistance.
Confirm proper stator operation using a suitable tachometer before making any exposures.
WARNING: HIGH VOLTAGE IS PRESENT ON THE H.V. AUXILIARY BOARD AT ALL TIMES THAT
THE GENERATOR IS SWITCHED ON. TAKE APPROPRIATE PRECAUTIONS WHEN
SERVICING THIS BOARD
2.7.1
Setting 120 / 240 VAC Boost Voltage
Follow the steps below to verify and configure the low speed starter boost voltage. This is factory
configured to 240 VAC.
1
Confirm the required boost voltage for the selected tube as described above. The requirement for
the vast majority of tubes in Table 1 of the supplement is 240 V. For tubes that require 120 V
boost, this is noted in the table.
2.
The boost voltage is configured via jumpers on the H.V. auxiliary board:
•
E16 to E15 selects 240 V boost.
•
E14 to E15 selects 120 V boost.
Swap the connection at E14 and E16 if the boost voltage needs to be changed. The jumper wire
(E16 - E15 or E14 - E15) will need to be replaced if making this change. Extra jumper wires are
attached to a bag on the lip on the inside of the cable access slot above the HV module. Select
the shortest wire from this bag that will connect between the desired tabs on the board that has
the proper terminations on the jumpers. Do not discard the existing jumper; place it in the jumper
kit to be available for future configuration changes.
Proceed to the next step if the jumper setting is correct.
NOTE:
THE ROTOR BOOST TIME MAY BE ADJUSTED IN THE RANGE OF 1 SECOND TO 4
SECONDS. THIS SHOULD BE SET PER THE X-RAY TUBE MANUFACTURERS
RECOMMENDATION, OR AS REQUIRED TO ENSURE PROPER ANODE ROTATION AT
THE END OF THE PREP CYCLE.
REFER TO
ROTOR BOOST
, UNDER
GENERATOR LIMITS
IN CHAPTER 3C FOR THE
PROCEDURE TO SET THE ROTOR BOOST TIME.
NOTE:
THE LOW SPEED STARTER BOOST MUST NOT EXCEED 5 CONSECUTIVE BOOSTS,
AND MUST BE FOLLOWED BY A MINIMUM 10 SECOND WAIT PERIOD.
3.
Confirm the proper boost voltage and proper anode rotation as described above.
