4.8 Description of Functions
LO This function serves to set the fail position of the actuator/valve. Initially during
this calibration the valve is driven to the fail position (hard stop). The user will
notice full pressure to Outlet Port 2 and zero pressure to Outlet Port 1. After a
short period of time pressure will increase in Outlet Port 1 and the valve will be
driven to the fully energized position and then back to the fail position. At this
point the user has the option to select the hard stop as low (zero) position or to
select an arbitrary position as low (zero) position.
