PROGRAMMING THE DUAL-SPEED STARTER

This section applies only to units fitted with the dual-speed starter.
The dual-speed starter must be programmed for the X-ray tube type used at this site. This is done via DIP
switch SW1 on the dual speed starter board.
The following tube functions are set with this switch:
•
High-speed start and run voltages.
•
Low-speed start and run voltages.
•
Brake time and brake voltage (high speed).
•
Boost times.
•
Boost time increments. Boost time may be increased in 100 ms steps in the range of 100 to 700 ms.
SW1 on the dual-speed starter must be set correctly to match the X-ray tube in use. Failure
to set this correctly may result in improper anode RPM and therefore may damage the X-ray
tube.
PLEASE BE SURE TO READ AND UNDERSTAND THIS SECTION FULLY BEFORE
PROCEEDING.
2.8.1

EPROM type / dual speed starter

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 HT
tank. Refer to chapter 6 for the EPROM replacement procedure, and to the table below for the
applicable EPROM part numbers.
DSS part number
901297-02
901297-12
901297-13
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 a label near the top left side of the dual speed starter
chassis. Keeping the dual-speed starter part number current will maintain configuration control of
the product.
2.8.2

Setting tube type

1. Select the desired tube type from table 2-2. Record the tube type number (housing and insert)
and the binary code as per the third column in the table. Please note that the tube compatibility
applies only to the housing and inserts listed, i.e. for the specific manufacturer(s) shown.
2. If the desired tube type is not listed, please contact CPI product support for assistance.
Use and disclosure is subject to the restrictions on the title page of this CPI document.
