Tube type setting on DIP switch SW1 for DSS Boards #728877-06 and #903132-02
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.
•
Boost times.
•
Boost time increments. Boost time may be increased in 100 ms steps in the range of 100 to 700 ms.
DIP switch 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.
1.
Select the desired tube type from Table 2 of X-Ray Tube Stator Compatibility Tables Supplement
746026-00. 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.

The recommended dual-speed starter used in CMP 200
DR X-ray generators will be one of the
following part numbers: 901297-
02
,
12
,
13
,
15
or
16
(400 VAC units), 901298-
02
,
12
,
13, 15
or
16
(480 VAC units), or 906664-21, 22, 23. Refer to the X-Ray Tube Stator Compatibility Table
Supplement 746026-00.
The stated capacitor values are equivalent capacitor values, and are derived from several
combinations of relay-selected series / parallel discrete capacitors, depending on the part
number. Refer to MD-0924 and MD-1069 in chapter 9 for details.

To determine if the dual-speed starter contained within your generator is compatible with the
desired tube as selected in step 1, note the part number of the dual-speed starter in your
generator. This is printed on a the back of the mounting plate, opposite the board assembly (see
