Malfunctions
− Invalid value for lower range value during fast conguration (FCO):
Lower range value (Code c02) and active detection of input signal failure (Code c31 =
YES)areavalidcombination.However,aplausibilityerrorarisesifaninputsignalfrom
0to20mAor0to10Visselectedthroughfastconguration(FCO).
Recommended action:SetCodec02toavalue≥1.0mAor≥0.5V.
− Invalid set point (Code c81):
Thesetpoint(Codec81)isnotwithintherangedenedbythelower(Codec86)andup-
per adjustment limits (Code c87).
Recommended action:Setthesetpoint(Codec81)ortheadjustmentlimits(Codec86/
c87) so that the set point is within the adjustment limits.
− 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:
Î 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limits(Codec86/c87)are
withinthelimitsoftheprocessvariablerange(Codec88/c89).SeeAnnexA.
We recommend performing a reset to default settings and reconguration (see the 'Opera-
tion' section) if plausibility problems due to changes in various parameters cannot be recti-
ed.
