2.13.0 PROGRAMMING THE DUAL SPEED STARTER

This section applies only to units fitted with the dual speed starter option.
The dual speed starter must be programmed for the X-ray tube type(s) used at this site. This is done via
DIP switches SW1 and SW2 on the dual speed starter.
The following tube functions are set with these switches:
•
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 and SW2 on the dual speed starter must be set correctly to match the X-ray tube(s) in
use. Failure to set these 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.

2.13.1 Setting tube type

1. Select the desired tube type from table 2-3. 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.
3. The generator is factory configured to support one type of stator only (for example "R" type stator),
therefore only stators of that type may be used with this generator. Refer to the customer product
description form in chapter 1D of this manual for compatible X-ray tubes.
REFER TO SECTION 2.13.2 IF IT IS DESIRED TO USE TUBES WITH STATOR TYPES NOT
COMPATIBLE WITH THIS GENERATOR, OR IF YOU ARE NOT CERTAIN THAT THIS
GENERATOR IS COMPATIBLE WITH THE STATOR IN YOUR TUBE.
4. Refer to figure 2-10. Set the DIP switch SW1 (for tube 1) with the binary code for the selected
tube. The binary code shown in the table programs the tube type (housing and insert), for
example housing type Varian Diamond with standard "R" stator and inserts per table 2-3 requires
SW1-1 to be set OFF, SW1-2 OFF, SW1-3 ON, SW1-4 OFF and SW1-5 OFF. This programs the
voltages, brake times, and boost times in table 2-3.
the preselected values (for example to run an older tube with worn bearings). For example, binary
000 gives zero increase, binary 001 gives 100 ms increase, binary 100 gives 400 ms increase,
and binary 111 gives a 700 ms increase in boost time. SW1-6 represents bit 1, SW1-7 bit 2, and
SW1-8 represents bit 3.
EXAMPLE:
Binary 100 = decimal 4 = 400 ms incremental boost time increase:
