2.2.5 Parts of Line
The load sensor often shares the weight with multiple parts of line. For accurate load indication the
GS550 must be programmed for the number of parts of line.
1. Press Menu and Enter to enter menu 1) Parts of Line.
2. Use Next and Back to select the load sensor; typically sensor number one is asso-
ciated with sheave one (the main hoist) and sensor number two is associated with
sheave two (the auxiliary hoist) etc.
3. Use Up and Down to adjust the number of parts of line.
4. Press Enter to save any changes and then press Exit twice to return to the opera-
tion display.
2.3 Rated Capacity Indicators
The GS550 can be programmed to assist the operator by indicating the working load limit (WLL)
from the crane specific rated capacity charts according to the angle and radius information re-
ceived from the boom mounted sensors.
