    5-1-1 Displaying Setting Values Basic Model • When the Mode Key is pressed in RUN mode, the K3NR displays a setting val- ue on the PV display (in the order of HH, H, L, and LL). • While the setting value is displayed, the corresponding SV display status indi- cator is lit.
  • Page 109 6. To return to the process value display, perform one of the following. • Repeatedly press the Mode Key until the process value appears. • Leave the K3NR with no key input for five seconds.
  • Page 110 Displaying and Changing Setting Values Section 5-1 SETTING EXAMPLE Set Value LED Display Follow the steps below to change the H setting value from 600 to 700 while the Model process value is displayed in RUN mode, provided that the HH setting value is already displayed on the SV display.

  • Page 111: Displaying And Resetting Of Maximum And Minimum Values

    The external RESET input signal is turned ON. The K3NR receives the reset command through communications. • When the K3NR is reset, the maximum and minimum values are set to the pro- cess value. Note The K3NR cannot be reset with the RESET/TEACH Key if the maximum/mini- mum value clear prohibit is ON in protect mode.

  • Page 112: External Input Signals

    The bank number can be displayed on the PV or SV display by pressing the Shift Key for more than one second while the K3NR is in measurement operation. If there is no key input for three seconds, the K3NR will be in measurement opera- tion again.

  • Page 113: Reset (Operating Mode F7)

    5-3-4 HOLD (Operating Modes F1 to F6) • The K3NR will stop the measurement if the HOLD input is ON. • When the HOLD input is ON, the K3NR will retain the process value, output, and BCD data effective immediately before the HOLD input.

  • Page 114: Hold (Operating Mode F7)

    5-3-5 HOLD (Operating Mode F7) • If HOLD input is ON, the counting value is on hold. • The K3NR is in counting operation continuously while HOLD input is ON and comparative output and BCD data are available regardless of the HOLD input.
