Step Action (membrane console)
3. Once the desired tube has been selected,
parameters for that tube are displayed
showing the default values. DO NOT
adjust the default values at this time.
When the desired tube is selected, the default limits are displayed (membrane console). Please consult the X-ray tube data sheet(s) before
making any changes.
The dual speed starter operates at 60 or 180 Hz (50 or 150 Hz for some tube types) independent of line frequency.
The low speed starter operates at 50 Hz for 50 Hz mains, or 60 Hz for 60 Hz mains. The generator samples the line frequency via a zero-
crossing detector on the generator interface board. Therefore, for units fitted with a low speed starter, the generator automatically derates the
60 Hz tube ratings for 50 Hz operation if required.
PLEASE DO NOT CHANGE ANY DEFAULTS UNLESS THE IMPACT OF THOSE CHANGES IS CLEARLY UNDERSTOOD. INITIAL
CALIBRATION SHOULD BE PERFORMED USING THE DEFAULT VALUES.
NOTE: BEFORE CHANGING X-RAY TUBE DEFAULT PARAMETERS, PLEASE FILL IN THE X-RAY TUBE AND GENERATOR
PARAMETER WORKSHEET, TABLE 3C-3. A BLANK FORM THAT SHOULD BE PHOTOCOPIED IS LOCATED AT THE END OF
THIS SECTION. THIS ALLOWS RECORDING OF THE DEFAULT VALUES AND THE NEW (CHANGED) VALUES.
Use these steps to set the tube limits and the associated parameters. Refer to the definitions in the previous table.
