Home Port Calibration
If maintenance is performed on the actuator that can
cause loss of calibration, the home port must be
recalibrated. Examples of maintenance that affect
calibration are removal of the actuator from the MPFS
and replacement of the position encoder. If a MPA is
removed from one MPFS and installed on another or if
a CPU module is replaced, the factory configuration
(.mpa) file for the MPFS must be loaded to the new
actuator and the selected home port calibrated.
To calibrate the home port position, remove the blind
cover from the selected home port. Use the hand
wheel of the MPA to position the plug seal over the
port as precisely as possible. Open DCMLink and
connect to Device. Right click Device Tag or select
Calibration button on the Menu Bar. Select the “Home
Port Calibration” as shown in Figure 15. To avoid
accidental setting of a new home port, the user is
required to enter a passcode of 43 to gain access. A
Pop-Up will appear as shown in figure 16 providing a
warning and allow entry of the passcode. The Port Raw
Value should be displayed in the Home Port Calibration
Box. Select Calibrate Home Port and review the value
before closing. The Home Port should be indicated on
the MPA LDM as the MPA is aligned with the Home
Port.
