Slack Rope
Systems programmed for four load sensors and four load sum indication can be programmed with
a slack rope sensor to warn against unwanted rope payout when the load touches down.
The Slack Rope Minimum Limit
The slack rope sensor compares the sum load to an adjustable slack rope minimum limit. When
the sum load goes below the slack rope limit a slack rope alarm is generated. The slack rope limit
is usually adjusted to less than the weight of all rigging below the load sensors. The default slack
rope minimum limit for is 1000 (lb or kg depending on load display units).
