The following section of code allows the analog parameter to be manually or automatically selected. The mode of operation is
selected with Rack 0, Word 1, Bit 3:
Set = automatic mode
Clear = manual mode
In manual mode the analog parameter is selected via Rack 0, Word 1, Bit 5, 6, 7. In automatic mode the analog parameter is
selected via the code.

Manual Parameter Selection
Output Local Rack analog parameter selection (Rack 0, Word 1, Bit 5,6,7) to SMP Control Word (Rack 2,Word 0,Bits
13,14,15)
Bit 13,14,15 – 000 or 001 = Average Current
010 = Thermal Capacity Utilized
011 = FLC Setting
100 = Current Unbalance
