ON/OFF Action Differential Gap:
ON/OFF control is possible when the Proportional band is set to “0” or “0.0.” In
ON/OFF control with Reverse action, when the Measured value (PV) is smaller than
the Set value (SV), the Manipulated output (MV) is 100 % or ON. When the PV is
higher than the SV, the MV is 0 % or OFF. Differential gap setting prevents control
output from repeating ON and OFF too frequently.
