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.

In Manual operation, the relay turns on while the
or key is pressed. Output limiter does not work.
