Serial number assignments for MIN and MAX
MIN signals are generated from set points below a median value of an analog
signal range. MAX signals are generated from set points above the median of an
analog signal range. To separate between MIN and MAX signals the following
rules apply:
MIN even serial numbers
NOC = 02, 04, ... 48
NCC = 52, 54, ... 98
MAX odd serial numbers
NOC = 01, 03, ... 49
NCC = 51, 53, ... 99
For a switching device that has both a NOC and a NCC, (changeover contacts),
the serial numbers would be assigned with a difference of 50 between them, i.e.
XG01 - XG51 or XG02 - XG52.
