5. Setup
Wire the power terminals only. After the power is turned on, the sensor input character and temperature
unit are indicated on the PV display and the input range high limit value is indicated on the SV display for
approximately 3 seconds. (Table 5-1)
(If any other value is set during the scaling high limit setting, the set 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 (PV) on the PV display and main set value (SV) on the SV display.
(While control output OFF function is working,
is indicated on the PV display.)

AT setting/Auto-reset setting
•
Selects auto-tuning Perform or auto-reset Perform.
•
If the auto-tuning is cancelled during the process, P, I and D values revert to the
previous value.
•
When auto-tuning has not finished after 4 hours, it is cancelled automatically.
•
Auto-reset is cancelled in approximately 4 minutes.
OUT1 proportional band setting
10
•
Sets the proportional band for OUT1.
•
The control action becomes ON/OFF action when set to 0 or 0.0.
•
0 to 1000 (2000 ), 0.0 to 999.9 ( ) or 0.0 to 100.0%
OUT2 proportional band setting
1.0 times
•
Sets the proportional band for OUT2.
OUT2 becomes ON/OFF action when set to 0.0.

Available only when Heating/Cooling control (option) is applied
•
0.0 to 10.0 times (multiplying factor to OUT1 proportional band)
Integral time setting
200 seconds
•
Sets the integral time.
•
Setting the value to 0 disables the function.
•
Auto-reset can be performed when PD is the control action (I=0).
•
0 to 1000 seconds
Derivative time setting
50 seconds
