Selecting New Home Port
The user may select any port as the new “Home Port”
in the field. When a new home port is selected, the
new home port is identified as Port 0 or 8 and the MPA
reassigns all other port numbers (1-7) in a
counterclockwise sequence around the MPFS. The
MPA recalculates the exact calibrated port position
based on factory calibration values so no accuracy is
lost.
To select a new home port, click on the desired
selection in Detailed Setup for User Home Port and
Label (0 or 8) as shown in figure 14.
Note
When a new home port is selected, it must be a port without piping
connected and must be fitted with a blind cover to allow for future seal
inspection and visual port alignment. Selecting a new home port will
cause the MPA to recalculate all calibration parameters based on the
factory calibration and store the new values to EEPROM.
Home port may be identified as either Port 0 or Port 8. The desired
designation may be selected by the CA configuration parameter as
shown on page 38.
Home Port LED Function
The home port LED on the LDM will now identify the
newly selected home port position. This LED is on
when the actuator is within 0.25 degrees of the
selected home port. When the blind cover of the home
port is removed in the field to inspect the seals, the
home zero may be verified and corrected if an error is
detected.
