Fault Legend Description
12B63 76643 11107 CAVE Input A CAVE function block has
detected an out of range value at
its "NumberOfSamples" or
"MaxNumberOfSamples" input, or
an infinite or NaN value at its
"InputSignal" input. No Yes Yes Minor FB_se
tup
Ensure that the CAVE function block
uses a range of 1 to 500 for
“MaxNumberOfSamples” input and
“NumberOfSamples” <
“MaxNumberOfSamples”. Ensure that
the value at "InputSignal" is not
infinity or NaN (Not A Number).
Infinity can be created by dividing by
zero or taking the logarithm of 0.
NaN values can be created with
equations such as square root of a
negative number or zero divided by
zero.
12B64 76644 11108 POSR_1
Input A POSR_1 function block has
detected an out of range value at its
“Roll_Diameter” input or its
RetainMaxValue input is equal to its
RetainMinValue input. No Yes Yes Minor FB_se
tup
Ensure that the POSR_1 function block
uses a value for its “Roll_Diameter”
input > 1. Ensure that the Dancer Signal
has been calibrated (i.e. its
RetainMinValue and RetainMaxValue
must both not equal zero).
12B65 76645 11109 POSR_2
Input A POSR_2 function block has
detected an out of range value for
one of its inputs labeled
“RatedLineSpd”,
“S_RPM_At_M_RPM”,
“RatedDancerStorage”, “R1_Factor”,
or “R2_Factor”. No Yes Yes Minor FB_se
tup
Ensure that the POSR_2 function block
inputs labeled “RatedLineSpd”,
“S_RPM_At_M_RPM”,
“RatedDancerStorage”, “R1_Factor”,
and “R2_Factor” have values > 0.
