The relationship between the control output variable and control period is de-
fined by the formula below:
Control output variable (%) =
The control output variable during ON/OFF control (when SW203-1 on the rear
panel is ON) is ON = 100% and OFF = 0%.
The auto-tuning operation begins when the Up Key is pressed. The PV and SV
return to the respective present value and set point displays. While auto-tuning
is in progress the AT indicator blinks.
To interrupt, press the Level and Display Keys again to display at. When at
appears, press the Up Key. When the interrupt is executed, the AT display dis-
appears and the process value is displayed.
When auto-tuning is completed, the AT indicator stops blinking and the P, I, and
D data is written to EEPROM.
Execute bank copy
When the Up Key is pressed, the data other than the set point is copied from
bank number 1 to banks 2 through 8.
Use this method to create data in banks 2 through 8 by slightly modifying the
data in bank number 1.
