− Invalidlimitsofprocessvariablerange(Codec88/c89):
The set point (Code c81) is within the range dened by the lower (Code c86) and upper
adjustment limits (Code c87). The lower limit of process variable range (Code c88) has a
greater value than the lower adjustment limit (Code c86) or the upper limit of process
variable range (Code c89) has a lower value than the upper adjustment limit (Code c87).
Recommendedaction: Adjust the limits of the process variable range (Code c88/c89) so
that they are identical to the adjustment limits (Code c86/c87) or that the adjustment lim-
its (Code c86/c87) are within the limits of the process variable range (Code c88/c89).
