section for switches other than the “WIRE FALLS SELECTOR SWITCH AND WIRE AND WIRE
FALLS DISPLAY LED” shown in the next section.
1. WIRE FALLS SELECTOR SWITCH AND WIRE FALLS DISPLAY LED (BLUE)
Fall mode must be set as “Searcher hook mode” when operating searcher hook. Using
searcher hook other than in “Searcher hook mode” may prevent issuance of the pre-warnings
and boom auto-stop even when the overload is near happening, and thus may result in crane
damage or the machine tripping over and may result in a serious accident.
Use this switch to change the number of wire falls.
•
Keep pressing the switch for 2 seconds or more.
The setting changes from “4-falls” to “Searcher hook mode”. At
the same time, the wire falls display LED changes from “4-falls”
to “Searcher hook mode (all lights ON)”, indicating that the
setting has changed.
• Then each time you press the switch for 2 seconds or more, the
setting of the wire falls changes from “Searcher hook mode” to
“1-fall”, then “1-fall” to “2-falls”, and then “2-falls” to “4-falls”.
NOTES
When changing the setting right after doing so, release your
hand from the switch, and then press the switch again.
