CAUTION: IMPROPER DIP SWITCH SETTINGS WILL RESULT IN IMPROPER ANODE SPEED
ROTATION WHICH CAN CAUSE OVERHEATING AND/OR DAMAGE TO THE X-RAY
TUBE.
WARNING: ENSURE PROGRAMMING THE DUAL-SPEED STARTER IS FULLY UNDERSTOOD AND
PROPERLY DONE, BEFORE PUTTING THE GENERATOR IN SERVICE.
This section applies only to units fitted with a Dual-Speed Starter (DSS). Different settings apply
depending on the DSS board number, and subassembly/tab number installed. Check the subassembly
number and tab number (as shown in Figure 2-10A), and the board number (printed on the board)
installed in your generator and follow the steps outlined in this section to program the DSS.
2.8.1
EPROM type / dual-speed starter - applies only to DSS Board #728877-06.
1.
The dual-speed starter EPROM is different for 400 V units and for 480 V units. If a 400 V unit is
reconfigured for 480 V, or a 480 V unit is reconfigured for 400 V, the dual-speed starter EPROM
will need to be changed. A spare EPROM (the complement of the EPROM that is in the dual-
speed starter) is in a bag attached to the lip on the inside of the cable access slot above the HV
module. Refer to chapter 6 for the EPROM replacement procedure, and to the table below for the
applicable EPROM part numbers.

2.
If you are making the conversion as per the previous step, use an indelible marker to change the
part number of the dual-speed starter assembly (901297-XX to 901298-XX, or vice-versa). The
dual-speed starter part number is printed on the opposite side of the board assembly, at the back
of the mounting plate (see Figure 2-10A). Keeping the dual-speed starter part number current will
maintain configuration control of the product.
NOTE:
DSS BOARD #903132 USES EEPROM* NOT EPROM**. THE TABLE SHOWN ABOVE
ONLY APPLIES TO DSS BOARD #728877-06. MORE INFORMATION ON UPGRADING
THE DSS BOARD #903132 USING EEPROM IS FOUND IN CHAPTER 6, REGULAR
MAINTENANCE.
NOTE:
THE ABOVE CONFIGURATION AND EPROM PART NUMBERS ONLY APPLY TO
SUBASSEMBLIES 901297-XX AND 901298-XX.
