    6. OPERATIONS CAUTIONS Connect the input signal wiring, and then turn ON the power. If the input signal wiring opens, the instrument judges the input is disconnected. Action at input break : Up-scale Action at input short circuit : Downscale No influence is exerted upon the instrument for power failure of 20 ms or less.
  • Page 51 6. OPERATIONS (4) Requirements for autotuning (AT) Autotuning (AT) is the function of automatically measuring, computing and setting the optimum PID constants. The requirements for autotuning (AT) start and suspension are described in the following. Autotuning (AT) is started/stopped by "PID/AT transfer" in the mode transfer (See P.19).

  • Page 56: Function Description

    9. FUNCTION DESCRIPTION 9.1 PV bias The value set in the PV bias is added to the actual input value to correct the input value. The PV bias is used to correct the individual variations in the sensors or when there is difference between the measured value (PV) of other instruments.

  • Page 57: At Bias

    9. FUNCTION DESCRIPTION 9.4 AT bias The AT bias is set when the autotuning function in which the measured value (PV) does not exceed the set value (SV) is activated. Our autotuning method performs ON/OFF control centering around the set value (SV), then calculates and sets each of the PID constants by hunting the measured value (PV).

  • Page 58: Alarms (Alm)

    9. FUNCTION DESCRIPTION 9.6 Alarms (ALM) Alarm (ALM) function sets up the alarm status when the measured value (PV) or the deviation reaches the alarm set values. In the alarm status, the alarm output is output from the digital output terminals, and the alarms are used to drive the equipment danger signals or the safety equipment.
