This position can be found by gently turning the two discs. The length of the air gap determines
the length of the reset play in the opposite direction.

Maximum height of lift
Once the limit switch is tripped, the load must travel 18" [50cm] minimum in the opposite
direction to reset the switch.
When furnished, the rotary limit switch, regardless of type, is mounted to the outside of the SM5
hoist body. This increases some hoist body outline dimensions.
*Designation of limit may vary on application. Switch number 2 and number 3 could have
different functions.
