Grasp the “lift tab” at the center of the front panel (near the top) and lift upwards approximately 1” to unhook the bottom of the front panel from the base of the cabinet. - Page 17 325E X-Ray Generator Summit Industries, Inc. Model Numbers F280 / A700 2. Connect x-ray tube a) High voltage cables (HV cables) – The high voltage generator requires the use of H.V. cables constructed with federal terminals. Note: Use extreme care when handling the H.V. cables to avoid damaging the plug or terminal pins.
- Page 18 325E X-Ray Generator Summit Industries, Inc. Model Numbers F280 / A700 3. Connect high voltage generator to control – a) The 25’ primary cable for the H.V. generator is connected to the control at the factory. The loose end, marked P1, P2, and GND, should be connected to the corresponding terminals of the H.V.
- Page 19 325E X-Ray Generator Summit Industries, Inc. Model Numbers F280 / A700 7. Auxilary exposure switch – Terminals have been provided in the control for connecting an auxilary exposure switch. They are on TB2 and are marked S1, s2, and S3. Refer to control circuit schematic for connection details.

325E X-Ray Generator Summit Industries, Inc. Model Numbers F280 / A700 F. Preliminary Electrical Checks and Adjustments 1. Line voltage adjustments – Terminals in the control on TBI are provided for coarse adjustments of line voltage. Measure the line voltage at the disconnect switch and relocate wire marked LVA to the corresponding terminal. - Page 21 325E X-Ray Generator Summit Industries, Inc. Model Numbers F280 / A700 Note that the 02249-000 timer board will display error codes per the table below. If more than one selection is invalid the highest number will take precedence. For example, an “invalid mA” and “kVp too low” would display as E04. Once the mA error is cleared the kVp low error E03 would then be displayed.
