The rotary limit switch is adjustable and provides over-travel protection for the upper and lower limits of hoist
travel. The limit switch is connected to the control circuit.
Note: Not available on Single Phase – 115 Volt Models
Note: Rotary limit switch assembly cannot be added to a Hoist. The Hoist must have
the rotary limit switch assembly provided at time of initial production.
Adjustment
The position of the air-gap between the two discs (red – gray) determines the stopping place. This position
can be found by gently turning the two discs. The length of air gap determines length of reset play in
opposite direction.

To reset the rotary limit once it has tripped, the load block assembly must travel approximately 11" [27cm] in
opposite direction.
