4.13 BROKEN BOOM CABLE PROXIMITY SWITCH
This system uses a proximity switch to detect excessive move-
ment of the cable block. If movement is detected the Cable
Break indicator will illuminate in the platform control panel.
No restrictions are made to the functionality of the control sys-
tem. It is the responsibility of the operator to take immediate
action.
To avoid damaging the proximity switch, install and adjust
after assembling the switch block, compression spring, and
torquing the wire ropes.
Adjusting the Proximity Switch
1. Thread the switch in until it contacts the adjuster block.
2. Thread the switch out 1/8 to 1/2 turn to achieve proper
sensing range.
NOTE: The LED light on the sensor illuminates when power is
applied and the sensor is within the proper range.
3. Tighten the jam nut.
