• Page 23: Operation

  After the unit is mounted to the control panel and wiring is completed, operate the unit following the procedures below. (1) Turn the power supply to the KT4H ON. After the power is turned on, the PV display indicates the input type, and the SV display indicates the input range high limit value (for thermocouple, RTD input) or scaling high limit value (for DC input) for approximately 3 seconds.

• Page 25: Basic Usage

  8. Basic usage 8.1 ON/OFF control In ON/OFF control action, the control output is turned ON when PV is lower than SV, and turned OFF when PV exceeds SV. Overshoot, undershoot and hunting phenomenon occur during ON/OFF action. Therefore, ON/OFF action is not suitable for control which requires accuracy.

• Page 26: Changing Pv Color

  8.4 Changing PV color (1) In the PV/SV display mode, press key for approximately 3 seconds while pressing key. The unit proceeds to the Setup mode, and the Input type selection item appears. (2) Press key several times until [54] PV color selection item appears. (3) Select the PV color with key.

• Page 27: Auto-Reset And Arw

  9. Auto-reset and ARW 9.1 Auto-reset Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the proportional band during the PD action. 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.

• Page 28: Auto-Tuning

  10. Auto-tuning In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made to fluctuate to obtain an optimal value. One of 3 types of fluctuation below is automatically selected. For DC input, the auto-tuning process will fluctuate around the SV for conditions of [1], [2] and [3] below. Notice •…

• Page 34: Sv Rise Rate, Sv Fall Rate Setting Action

  11.11 SV rise rate, SV fall rate setting action [46] SV rise rate and [47] SV fall rate can be set in the Setup mode. (p.21) When the SV is adjusted, it approaches the new SV by the preset SV rise rate or SV fall rate. When SV is adjusted while SV is rising (or falling), SV at the given time becomes a starting point, and approaches the new SV.

• Page 35
  When power is turned on or when control output OFF function is cancelled by the key, SV changes as follows in relation to PV. (e.g.) SV=200 , SV rise rate=6 /Min, SV fall rate=30 /Min [When SV>PV] Temperature SV=200 SV display 200 C (on the SV display) approaches by the SV rise rate.

• Page 36: Communication

  Serial communication and Tool port communication cannot be used together. When performing Serial communication, remove the tool cable (AKT4H820) from the USB port of the PC and tool connector of the KT4H/B. When performing Tool port communication, it is not required to remove the Serial communication cables.

• Page 37
  Do not connect a terminator with the communication line because each KT4H/B has built-in pull-up and pull-down resistors instead of a terminator. Even though a terminator is not necessary for communication between the PLC and KT4H/B, if a terminator is required due to signal reflection, connect the terminator on the PLC side.

• Page 38: Communication Parameter Setting

  12.3 Communication parameter setting Set each parameter following the procedures below. Setting item numbers such as [17, [19], etc. are the same as those on the “6.4 Operation flowchart”. (p.12) Proceed to Auxiliary function setting mode. Press key while pressing key in the PV/SV display mode.

• Page 39: Communication Procedures

  12.4 Communication procedures Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the KT4H/B (hereafter Slave). Master Slave • Response with data Command When the master sends the reading command, the slave Data responds with the corresponding set value or current status.
