The switch is factory-set to OFF.
Set each loop to either straight line (no approximation) or square root approxi-
mation.
Set to "enabled" to use input loop 2, or to "disabled" to use only input loop 1. It is
not possible to use only input loop 2.
Note Always set this switch to the ON (disabled) position when input loop 2 is not
used. A sensor error occurs if this switch is set to the OFF (enabled) position
when no temperature sensor is connected to loop 2.
This setting selects the SP storage memory. Set it to ON or use RAM Write com-
mands if the writing is to be frequently changed.
Selects whether setting and SVs displayed on the Data Setting Console are in
Celsius or Fahrenheit.
Reverse:
The output is increased when the measured temperature is below the SP (i.e., a
negative temperature difference).
Normal:
The output is increased when the measured temperature is above the SP (i.e., a
positive temperature difference).
Selects the method of control.
