5. Setup
Wire the power terminals only. After the power is turned on, the sensor input characters and temperature
unit are indicated on the PV display and the input range high limit value is indicated on the SV display for
approx. 3 seconds (Table 5-1).
(If any other value is set during the scaling high limit value setting, the value is indicated on the SV display.)
During this time all outputs and the LED indicators are in OFF status.
Control will then start, indicating the input value on the PV display and SV on the SV display.
(While control output OFF function is working,

AT setting
• Performs PID auto-tuning. However when PID auto-tuning has
not finished after 4 hours, PID auto-tuning is cancelled automatically.
•
If Auto-tuning is cancelled during the process, P, I, D values return to the previous value.
• PID auto-tuning cancellation:
OUT proportional band setting
• Sets the OUT proportional band.
• The control action becomes ON/OFF action when set to 0 or 0.0.
• 0.0 to 110.0% [Percentage of the scaling span (scaling high limit-scaling low limit)]
Integral time setting
• Sets the integral time.
• Setting the value to 0 disables the function.
• Not available for ON/OFF action.
• 0 to 1000 seconds
Derivative time setting
• Sets the derivative time.
• Setting the value to 0 disables the function.
• Not available for ON/OFF action.
• 0 to 300 seconds
Anti-reset windup setting
• Sets anti-reset windup.
• Available only for PID action.
• 0 to 100%
