9.14 Plausibility error
Due to an invalid combination of interacting parameters in the conguration level, a plausi-
bility error arises which is indicated by PLAU blinking on the display. A correction of the in-
teracting parameters resets the error message.
Causes of plausibility error
− Invalidapplicationselected(whenCodec01=C):
"Pt1000" (Code c01 = C) is set as the source (only available for PID controller applica-
tion, Code 6 = PID). Afterwards, the application is changed to "Positioner" (Code 6 =
POSI) or "Temperature closed-loop control upon input signal failure" (Code 6 = POSF),
causing a plausibility error.
Recommendedaction: Set Code 6 to PID controller.
− Invalidapplicationselected(whenCodec01=VIA):
"Interface" is set as the source (Code c01 = VIA). Afterwards, the application is changed
to "Temperature closed-loop control upon input signal failure" (Code 6 = POSF), causing
a plausibility error.
Recommendedaction: Set Code 6 to positioner or PID controller.
− Invalidvalueforlowerrangevalue(Codec02):
A value <1.0mA or <0.5V is set in Code c02 combined with an active detection of in-
put signal failure (Code c31 = YES).
Recommendedaction: Set Code c31 to NO or c02 to a value ≥1.0mA or ≥0.5V.
− 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.
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.
