Control     

Control action 

• PID action (with auto-tuning function) 
• PI action: When derivative time is set to 0 
• PD action (with manual reset function): When integral time is set to 0 
• P action (with manual reset function): When derivative and integral time are set to 0 
• ON/OFF action: When proportional band is set to 0 

              OUT proportional band  : 0.0 to 110.0% (ON/OFF action when set to 0.0) 
 

Integral time 

  : 0 to 1000 seconds (Off when set to 0)   

 

Derivative time 

: 0 to 300 seconds (Off when set to 0) 

 

OUT proportional cycle  : 1 to 120 seconds 

 

ARW      

: 0 to 100%  

 Manual 

reset 

: 

Proportional band converted value 

 

Output limit 

: 0 to 100% (DC current output type: –5 to 105%) 

 

(Not available for ON/OFF action)

• Alarm output   

[Alarm, Loop break alarm and Heater burnout alarm (option) utilize common output terminals.] 
The alarm action point is set by 

  deviation from the SV (excluding Process alarm) 

and when input is out of the alarm setting range, alarm (EVT) turns ON or OFF (High/Low limit   
range alarm). When Deenergized is selected in the Energized/Deenergized selection, alarm 
(EVT) is activated conversely. 
Setting accuracy 

: The same as indication accuracy
