CHAPTER 5 PARAMETERS
E5CK
5–24
LBA detection time
Conditions of Use
The LBA (Loop Break Alarm) function
must be assigned as an output.
Ă• This parameter is automatically set by AT execution.
Ă• The LBA is output if the change width of the process value falls below 0.2 %fullĆscale
of the time preset to this parameter when the manipulated variable is set in the MV
upper limit" or MV lower limit" parameters.
Ă• The LBA function is disabled when this parameter is set to 0".
Setting Range
Unit Default
0 to 9999 Second 0

MV at reset
MV at PV error
Conditions of Use
Advanced PID control.
Ă• The MV at reset" parameter sets the manipulated variable when operation has
stopped.
Ă• The MV at PV error" parameter sets the manipulated variable when an input error
occurs.
Control Method Setting Range
Unit Default
Standard -5.0 to 105.0 % 0.0
Heating and cooling -105.0 to 105.0 % 0.0
The manipulated variable at the cooling side during heating and cooling control is
expressed as a negative value.
