7.3 How to Use Error Output
The E5CK controller allows you to assign error output to terminals as out-
puts.
For details on output assignments, see 3.3 Setting Output Specifications
(page 3-5).
•
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 4-9.
•
LBA allows you to detect the following errors:
(1) Heater burnout
(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 when input
is in error. When this error occurs, remedy by following the description
for “Input error” (page 7-3).
•
If you assign error 2 as the output, an error can be output when the A/D
converter is in error. When this error occurs, remedy by following the
description for “A/D converter error” (page 7-3).
