8.3 How to Use the Error Output
The E5EK-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 page 4-26.
•
LBA allows you to detect the following errors:
(1) Heater burnout (HBA)
(2) Output error (contact weld, damaged transistors, etc.)
(3) 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 or auxiliary output 2 when input is in error. When this error
occurs, remedy by following the description for “Input error”.
•
If you assign error 2 as the output, an error can be output to auxiliary
output 1 or auxiliary output 2 when the A/D converter is in error.
When this error occurs, remedy by following the description for “A/D
converter error”.
