Rope payout
Typically the rope payout sensor is factory installed
on the line riding tensiometer load sensor (figure
above). Alternatively the rope payout sensor may
be installed on an appropriate sheave (figure
below). Power supply must be provided to the rope
payout sensor. A GS550 display can then be
programmed to communicate with the sensor and
to indicate rope payout (length) and rope speed.
Zero the rope payout using the Tare menu before
calibration.
