Boom position
Boom Position is designed to allow the boom height to be set accurately to allow furling
systems to work with optimum effi
ciency.
Calibration of Boom Position
Boom Position is an arbitrary value and the value is not used in further calculations, as such an
absolutely accurate calibration is not required.
If Boom Position is not available in the menu it is necessary to determine the linear input in
use and confi gure it correctly.
Position the boom at the optimum point for furling/reefi ng, set POINT 1 to be 0.0, the voltage
is automatically recorded and can be noted from VOLTS 1 if required.
Position the boom at its highest normal position, set POINT 2 to be 5.0, the voltage is
automatically recorded and can be noted from VOLTS 2 if required.
After calibration check that the value displayed for Boom Position is positive if the boom is
high of the furling position, zero at the furling position and negative when the boom is below
the furling position.
Before furling it is a simple case of adjusting the boom height until Boom Position reads 0.0.
