7. Running

7.1 Start running.

After the controller is mounted to the control panel and wiring is completed, operate the unit following the
procedures 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 unit
are 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 status
Control 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 status
The 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 indication
is selected during PV/SV indication selection, "
• Program control run status
The MEMO/STEP display indicates step number, and the PV/SV display indicates input value or current
step 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 control
Control starts so as to keep the control target at the SV.
• Program control
Program control run
To perform program control run, press the
PV start: When the program control starts, SV and step time are advanced to the PV, then the
program control is performed.
(e.g.) PV is assumed to be 100
If the program control is performed, the step SV advances from 0
time also advances from 1:00 to 0:30.
Program control stop
To stop program control, press the
the controller reverts to the program control standby mode.
Action after power is restored
If power failure occurs during the program control run, the control resumes from the point at which
power failure occurred.
If power failure occurs during program control standby mode, the control resumes from the program
control standby mode.

• Converter
In 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.
