Necessary for Loop control with PV auto-selector for 3 inputs or 4 inputs
For the model with optional suffix code /DR:
Refer to the function block diagram of
Loop control with PV auto-selector (2 inputs).
When sensor
burnout occurs
In Estimating-type position proportional control, the limiter function does not
work on output operation.
The reverse-signal relay turns on when being limited by low limit.
The direct-signal relay turns on when being limited by high limit.
Sensor burnout occurs when PV, RSP, AIN2, or AIN4 input burnout occurs.
However, burnout is not detected if input is not conncted.
Position Proportional Computation Output cannot be calculated by ladder program.
In Manual operation, the relay turns on while the
or key is pressed. Output limiter does not work.
