Adjustments 2

Adjusting the 40-4 HDR I.I. Power Supply 2

The control and adjustment component of t he I.I. power supply is adjusted at the factory
along with the high voltage components . These work steps cannot be carried out i n the field.
This means that if there is a defect of the control and adjustment component or of a high
voltage component, the complete I.I. power supply must be replaced.
The 40-4 HDR power supply is mounted on a bracket and can only be r eplaced
completely.

NOTICE

General 2

Use the voltage values given in the test certi ficate to check or reset the adjustment
parameters of the I.I..
The voltages are set in the factory f or the replacement I.I..
Setting the I.I. voltage levels (refer to circuit diagram X2181). 2
For optimal adjustment of the I.I., the reference voltage values given in the I.I. te st certificate f or the i ndividual electr odes have to be set at the power supply. After you switched on the power supply, wait 10 minutes before you begin setting the voltage values. (Perform only when the power supply is being replaced).

Gettering the Image Intensifi e r 2

The I.I. is switched to continuous gettering.

Instructions for Correcting Malfuctions 3

If there is a resolution problem with the image intensifier, the volt age values must be
checked per the test certificat e, and if needed, must be readjusted.
It is particularly import ant to check the lead connections from the I.I . power supply to the
the image intensifier; make sure the re is good contact.
When plugging in the high voltage connector , the creep paths must be clean. If
necessary, clean them with ether; do not use alcohol.
If there really is a malfunction i n the I.I. power supply, the complet e power supply must
be replaced (high voltage componen ts with control and adjustment component)!
