Level 1 Mode
AT Execute/Cancel
• Selects the limit cycle of MV change width (40% or 100%) for execution. After AT
execution, the "PID" and the "LBA detection time" (Loop Break Alarm) parame-
ters are automatically set.
Function
• During heating and cooling control or position-proportional control, only 100%AT
can be executed.
• To execute 40%AT, select [
execution of auto-tuning, the AT LED flashes. However, note that during heating
