CHAPTER 5 PARAMETERS
Level 2 Mode
LBA detection time
• This parameter is automatically set by AT execution.
• The LBA is output if the change width of the process value falls below 0.2 %full-
scale of the time preset to this parameter when the manipulated variable is set in

MV at reset
MV at PV error
• The "MV at reset" parameter sets the manipulated variable when operation has
stopped on a standard type controller. On a position-proportional type controller,
this parameter sets the action (close/hold/open) when operation has stopped.
Function
• The "MV at PV error" parameter sets the manipulated variable when an input
error occurs. On a position-proportional type controller, this parameter sets the
action (close/hold/open) when an input error occurs.
