Page 43: Self Tuning
8.5 Self Tuning Unlike automatic tuning which is executed only when the operator intends, Self tuning is the function to execute automatic tuning when the stability of control exceeds the limit or setting changes in steps, etc. by monitoring the existence of deviation, hunting, etc. continuously from the controller. Since the output is not changed in steps as in automatic tuning, there is no disturbance by tuning. -
Page 44: Selection Of Operation Method
8.6 Selection of Operation Method Operation method is selected by the setting on SP remote/local, SP No./PID No. selection and PID mode. The SP No. switching method and the SP and PID to be used are decided by these settings. The relationship between these settings and action is shown in the table below: ×: Setting does not affect. -

Page 46: Chapter 9 Procedure For Major Functions
Chapter 9 Procedure for Major Functions 9.1 Alarms 9.1.1 Pause Alarm This function is validated after turning on the power or after changing the setpoint (SP) or alarm value. An alarm doesn't occur even if it is in an alarm range (both or either of PV and SP at values where an alarm is occurred if usual) if it doesn't pass in a normal range (both PV and SP at values where an alarm is not occurred). -

Page 48: Square Root
9.3.2 Square Root Enabled for mV (except 0.0 to ＰＶ ±10.0mV), V, mA input. The （％） following formula is used to ↑ calculate the process variable (PV) from input: PV＝ √input x 10 Furthermore, PV= 0 is set compulsorily if input is smaller than the input cutoff level. -
Page 49: Profiling Control
9.6 Profiling Control It is a type of cascade control in which the range of remote setting value change for the slave controller is restricted. Master controller adds the value obtained by converting -50 to +50% with 50% PID computing result as 0% into ±7% with the master setting value converted into %, and transmits it to the slave controller. -
