8.6 Performing Auto-reset

Notice
• Auto-reset is cancelled in approximately 4 minutes. It cannot be cancelled while performing
this function.
• If input is burnt out, Auto-reset will be forced to stop.
Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within
the proportional band during the PD control. Since the corrected value is internally memorized, it is
not necessary to perform the Auto-reset again as long as the process is the same.
However, when OUT1 proportional band (P) is set to 0 or 0.0, the corrected value is cleared to 0 (zero).
