Calibration
For the ACS to operate properly, it needs to know the trim tab type, position, and current consumption.
This information is automatically acquired and stored in memory during calibration. Before you start,
ensure that no obstacles hinder the free run of the tabs.
The AUTO indicator blinks to indicate that
calibration is needed. Press the uppermost
and lowermost buttons simultaneously for 4
s to start the calibration. Keep the buttons
depressed for another 8 s while the ACS is
calibrating.
The ACS will now run the trim tabs to their
uppermost position. The tabs are then run
downwards and back up again.
This calibration may take up to 60 seconds and should not be interrupted. After completion, the
indicator LED’s stop blinking. The port trim tab position is now shown by the left bar and the starboard
by the right bar.
