187. Running7.1 Start running.After the controller is mounted to the control panel and wiring is completed, operate the unit following theprocedures below.(1) Turn the power supply to the KT2 ON.For approx. 3sec after the power is switched ON, the sensor input characters and the temperature unitare indicated on the PV/SV display. See (Table 5.2-1) on page 8.During this time, all outputs and LED indicators are in an OFF status.After that, control starts, indicating the following, depending on the controller status.• Fixed value control statusControl starts, indicating memory number on the MEMO/STEP display and PV (process variable) or SV(main set value) on the PV/SV display. (If PV indication is selected during PV/SV indication selection,PV is indicated. If SV indication is selected during PV/SV indication selection, SV is indicated.)• Program control standby statusThe MEMO/STEP display is turned off, and the PV/SV display indicates input value or " ".(If PV indication is selected during PV/SV indication selection, PV is indicated. If SV indicationis selected during PV/SV indication selection, " " is indicated.)• Program control run statusThe MEMO/STEP display indicates step number, and the PV/SV display indicates input value or currentstep temperature. (If PV indication is selected during PV/SV indication selection, PV is indicated.If SV indication is selected during PV/SV indication selection, current step temperature is indicated.)• When control output OFF function is working;The MEMO/STEP display is turned off, and the PV/SV display indicates " ".(2) Input each set value.Input each set value, referring to “6. Setup”.(3) Turn the load circuit power ON.The controller starts as follows depending on the setting.• Fixed value controlControl starts so as to keep the control target at the SV.• Program controlProgram control runTo perform program control run, press the key. At this time the program control starts with PV start.PV start: When the program control starts, SV and step time are advanced to the PV, then theprogram control is performed.(e.g.) PV is assumed to be 100 in the program pattern of Section “6.1 Main setting mode”.If the program control is performed, the step SV advances from 0 to 100 , and the steptime also advances from 1:00 to 0:30.Program control stopTo stop program control, press the key for approx. 1 second. The program control stops, andthe controller reverts to the program control standby mode.Action after power is restoredIf power failure occurs during the program control run, the control resumes from the point at whichpower failure occurred.If power failure occurs during program control standby mode, the control resumes from the programcontrol standby mode.Progressing time error after power is restored: Within 1 minute regardless of step time unit• ConverterIn the case of DC current output type, each input value (thermocouple, RTD, DC current, DC voltage)is converted to 4 to 20mA DC and outputted.Input/output response is approx. 1 second.When using an alarm action, select Process alarm during A1, A2 type selection.
