Adjusting the I.I. minivoltage supply

CAUTION
NOTE
•
Hold the covers firmly when removing or installing them!
•
Remove the cover from the front of the C-arm by removing the screws (I.I. side).
•
Move the I.I. into the service position (see Section "I.I. service position").
•
Loosen the two fastening screws of the control unit on the I.I. flange of the C-arm.
•
Carefully remove the control unit from the C-arm.
•
Adjust the voltages E1 (test point UE1), E2 (test point UE2), E3 (test point UI15) and
anode (test point UI30) according to the I.I. protocol, see also wiring diagram.
•
Reinstall the control unit in the C-arm.
•
Reinstall the cover of the C-arm.
•
Perform the IQ quick test.
•
Check the function and setting of the collimator and adjust if necessary.
•
Check the function and setting of the monitor collimator display, adjust if necessary.
•
Check the 0° position of the camera rotation (see "Replacing the VIDEOMED DC, 0°
position").

Danger of injury!
In the case of non-compliance slight to medium physical injury
and/or damage to property can arise.
The C-arm cover contains counterbalance weights and weighs
> 10 kg. Hold the covers firmly when installing or removing them.
Before loosening the C-arm cover, move the C-arm into its middle
orbital position. After loosening the C-arm cover, do not move the
C-arm into its orbital end positions (I.I. in orbital end position).
The cathode wire of the I.I. (black wire connected to plug CON1.8
on the control unit) is sometimes very short.
The cathode wire can be extended for easier access to the test
points and potentiometer on the control unit. To extend the wire,
split the wire and strip off the insulation from the wire ends.
Place 2 pieces of shrink tubing of suitable diameter over the wire
ends. Solder an approx. 25 cm wire of 0.75 mm². Insulate the wire
ends with shrink tubing.
