3. Set the “LBA detection time” parameter to two times the measured time.
LBA Level • Set the control deviation when the control loop is working properly.
• The default is 8.0 (°C/°F) for Controllers with Thermocouple/Resistance
Thermometer Universal-inputs and 10.00% FS for Controllers with Analog
Inputs.
LBA Band • There is assumed to be an error in the control loop if the control deviation
is greater than the threshold set in the “LBA level” parameter and if the
control deviation does not change by at least the value set in the “LBA
band” parameter.
• The default is 3.0 (°C/°F) for Controllers with Thermocouple/Resistance
Thermometer Universal-inputs and 0.20% FS for Controllers with Analog
Inputs.
Operating Procedure Perform the following procedure to use the loop break alarm.
In this example, the LBA detection time is set to 10, the LBA level is set to 8.0,
