█ Control loop break alarm (LBA)
If the measured value (PV) is within the proportional band (PB),
the LBA operation is not performed and LBA operation starts after it is out of the proportional band.
• Loop break alarm (LBA) operation
- When the output is “0” % and the control output operation is a direct operation
It operates when the measured value does not rise more than 2 ℃ (2 ℉, 2 %) within the time set in LBA.
- When the output is “0” % and the control output operation is the reverse operation
It operates when the measured value does not fall more than 2 ℃ (2 ℉, 2 %) within the time set in LBA.
- When the output is “100” % and the control output operation is a direct operation
It operates when the measured value does not fall more than 2 ℃ (2 ℉, 2 %) within the time set in LBA.
- When output is “100” % and control output operation is reverse operation
It operates when the measured value does not rise more than 2 ℃ (2 ℉, 2 %) within the time set in LBA.
• Hysteresis of loop break alarm (LBD)
- LBD sets the hysteresis of the loop break alarm output in the parameter.
- Even if an alarm occurs due to LBA operation, if the measured value is within the LBD,
the alarm operation does not occur.
