8.3 How to Use the Error Output
The E5CKĆT controller allows you to assign error output to terminals as
outputs.
For details on output assignments, see 3.3 Setting Output Specifications
(page 3Ć7).
Ă• LBA (Loop Break Alarm) can be used as a means for detecting loop
breaks when the control loop is not functioning normally. For details, see
4.8 LBA (page 4Ć16).
Ă• LBA allows you to detect the following errors:
(1) Output error (contact weld, damaged transistors, etc.)
(2) Sensor error (constant input values, etc.)
Ă• If you use the LBA function, set the loop break detection time matched
to the control characteristics in the LBA detection time" parameter
(level 2 mode).
Ă• If you assign error 1 as the output, an error can be output to auxiliary
output 1 when input is in error. When this error occurs, remedy by folĆ
lowing the description for Input error".
Ă• If you assign error 2 as the output, an error can be output to auxiliary
output 1 when the A/D converter is in error. When this error occurs, remĆ
edy by following the description for A/D converter error".
