The E5CK T controller allows you to assign error output to terminals as
outputs.
For details on output assignments, see 3.3 Setting Output Specifications
(page 3 7).
• 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 4 16).
• LBA allows you to detect the following errors:
(1) Output error (contact weld, damaged transistors, etc.)
(2) Sensor error (constant input values, etc.)
• 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).
• 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 fol
lowing the description for Input error".
• 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, rem
edy by following the description for A/D converter error".
