SELF-CALIBRATION
Self-Calibration establishes the position range
of the Biffi EHO actuator. The Biffi EHO has the
ability to automatically find its precise full open
and full close set points after adjustments to the
mechanical stops are completed.

SELF-CALIBRATION CYCLE COUNT
Set the number of full cycles for the
Biffi EHO to cycle during self-calibration.
One cycle is defined as one open and one
close stroke.

MAXIMUM OPERATING PRESSURE
Set the maximum hydraulic pressure
of the Biffi EHO during standard
operation. If the operating pressure exceeds
the MAXIMUM OPERATING PRESSURE, an
Over Pressure Alarm[P][F] will be displayed.
