5.2 Collimator Lamp voltage Selection Procedure
Before starting this procedure ensure that the XT control board and the Collimator lamp are
accessible (refer to Collimator SM for instructions).
1. Select on digital multimeter:
− V
AC
− Auto range (or manual range > 240 V
2. Measure the actual voltage at Collimator lamp bulb base with the lamp switched ON.
3. With The GE type lamp, ensure that voltage is greater than 23V when the electrical jumper
J11 is in place.
4. With The Philips type lamp, if the voltage is within 21.5−V
of the electrical jumper position next to J9 or J10 cannot be used to set the voltage closer to
22.5V
AC
your system.
If so, then move jumper from J10 to J9. (Refer to table below for tap selection voltages).

5. If the voltage is out of the range 21.5 − 24 V
(between J100−1 & J100−5). If it is not 230 V
Dir. 2137354−100 and correct line voltage setting on generator.
If the input line is correct, move the electrical jumper to a more appropriate position in order to
keep the voltage within 21.5 and 24 V
greater than 23 V
6. Record actual final voltage reading at Collimator lamp bulb base only if you have to do HHS
measurement on your system.
