Description:
The process variable engineering unit is composed of three characters, which will be applied to the indication of
the parameters P0040 and P0041. The parameter P0530 defines the left most character, P0531 the center and
P0532 the right most.
The characters that can be chosen correspond to the ASCII code 32 to 127.
Examples:
A, B, ..., Y, Z, a, b, ..., y, z, 0, 1, ..., 9, #, $, %, (, ), *, +, ...
−To indicate "bar": −To indicate "%":
P0530 = "b" (98) P0530 = "%" (37)
P0531 = "a" (97) P0531 = " " (32)
P0532 = "r" (114) P0532 = " " (32)

Description:
Those parameters are used in the functions of the digital/relay outputs, with the purpose of signalizing/alarm, and
they will indicate:
Process Variable > VPx and
Process Variable < VPy
The values are in percentage of the process variable full scale:
