SECTION 2 CONFIGURATION PROCEDURE
Configuration and Calibration procedures should only be
performed at field if Portable Control Board, Control Driver
Board or the High Voltage Transformer are replaced or the
EEPROM memory is re-initialized.
All procedures described in this Service Manuals are
performed from the Control Panel of the X-ray Unit.
Configuration provides the initial settings and checkout procedures that must
be carried out before starting to work with the Unit. Functional characteristics
of this Generator are defined during Configuration.
Calibration data and some configuration data are stored in the extended
memory area of the non-volatile memory U25-EEPROM Microcontroller. It is
located on the Portable Control Board (A3175--03).
Do not supply the main power until specifically instructed in
this document.
2.1 CONFIGURATION OF DIP SWITCHES
The Dip Switches located in the Portable Control Board (A3175-03) define the
Unit configuration:
DipSwitchSW1 Description
1* ON = Service mode enabled
OFF= Service mode disabled
2ON = Hardware errors disabled
OFF= Hardware errors enabled
3ON = Demo mode enabled
OFF= Demo mode disabled
4ON = Filaments disabled
OFF= Filaments enabled
* NOTE.-- Access to Service mode can be also performed using the keyboard as indicated in
Section 2.2 while dipswitch is in “OFF” position.
All Dip Switches are Factory set to OFF position for normal operation.
