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.
Step 1. Press Menu → Enter to enter menu 1) Parts of Line.
Step 2. Use Next and Back to select the load sensor; typically sensor number one is
associated with sheave one (the main hoist) and sensor number two is associated with
sheave two (the auxiliary hoist) etc.
Step 3. Use Up and Down to adjust the number of parts of line.
Step 4. Press Enter to save any changes and then press Exit twice to return to the operation
display.
