NOTE A
-12 volts DC is required for the Sensor Board’s conductivity circuits and the Blood Pressure Module:
•
Referring to the Figure 4B (next page), if the machine is equipped with the Old Style Power Logic
Board the miniature -12 volt ‘Convertor Board’ is required. This board plugs into the motherboard’s
nine (9) pin TEST Connector (#1).
•
If equipped with the New Style Power Logic Board (released in 2008) the -12 volt supply is
incorporated into the Power Logic Board and the ‘Convertor Board’ is NOT necessary.
•
Both the Old and New Style Power Logic Boards are compatible with 2008K and K 2 machines but
CAUTION must be exercised. If an Old Style Power Logic Board is installed in a machine
equipped with the New Style Power Logic Board the ‘Convertor Board’ MUST ALSO be installed
otherwise a “Cond Ref” or “Cond Offset” error will occur. If a New style Power Logic Board is
placed into a machine equipped with the Old Style Power Logic Board the ‘Convertor Board’
should be removed!
