Display Assignment:
Displays lines 1 & 2 may be assigned to
process values for Channels A (Ch-A, current), V (Ch-V, voltage),
or P (Ch-P, apparent power); toggle between (Ch-A & Ch-V, Ch-A &
Ch-P, Ch-V & Ch-P, and Ch-A, Ch-V, & Ch-P); relay set points; max
and/or min values for CH-A, Ch-V, or Ch-P; CH-A and units; Ch-V
and units; Ch-P and units; or Modbus input. The lower display may
also be set to show engineering units or be off, with no display.
