CPI Canada Inc. Installation 2
5. For units fitted with the optional dual-speed starter board 728877-06: 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 as described in the section EPROM type / dual-speed starter. Confirm
that this has been done.
___ Check
For units fitted with the optional dual-speed starter board 903132-xx, the line input voltage is
sensed automatically by the board and no component needs to be changed.
2.11.0 TUBE mA AUTO CALIBRATION
It is recommended that the generator be tested at this point with only the X-ray tube and rotor / high-
tension cables connected. The generator should be able to complete an X-ray tube seasoning and
calibration cycle without other equipment connected to the generator (other than the basic interlocks as
noted below). This will allow for easier fault isolation as each section of the system is connected and
tested.
Before being able to make X-ray exposures, the room door interlock must be closed and the thermal
switch must be closed. The interlocks cannot be deprogrammed during tube mA auto calibration.
It is recommended that the tube(s) be conditioned (seasoned) before beginning tube auto calibration,
particularly if the tube has not been used for some time. Refer to chapter 6.
Before beginning tube auto calibration, the tube(s) used in this installation must be properly selected, and
the generator limits should be programmed. Refer to chapter 3C.
2.12.0 FINAL CHECKS
The room interface connections may now be completed. These items are described in 2.6.8.
• When finished all wiring, check that all connections are tight and secure.
• Check that all cables are dressed neatly inside the main cabinet, and secured as necessary.
• Reconnect any grounds that have been removed from covers. Then reinstall all covers before placing
the generator into service.
• For units with the touchscreen console, perform touchscreen calibration. Refer to chapter 3C for the
proper calibration procedure.
NOTE: THE INSTALLER SHOULD ENSURE THAT ALL CABLE CONNECTIONS TO THE
GENERATOR ARE SECURE, AND ALL CABLES EXTERNAL TO THE GENERATOR
ARE ADEQUATELY PROTECTED AGAINST ACCIDENTAL DISCONNECTION.
