8.1 Voltage Setting Procedure
8.1
Voltage Setting Procedure
On the back of the PDP, in the top right hand corner, you find the Voltage Setting label:
Figure 8-1 Voltage setting label
This Voltage Setting label shows the following messages:
Table 8-1
If the voltage adjustments Vs and Va on the Power Supply Unit must be performed, depends on the version of the Power Supply Unit (see
table 8-2).
Table 8-2
This table also shows if the Vs and Va control loop must be switched ON or OFF.
The voltage adjustments Vw and Vx are done automatically via ComPair. After exchange of the Logic Board, click on ‘Ship out’. The settings
from the old Logic Board will be restored in the new Logic Board.
