🔍 Key Concepts

• Trace how the LSL contact is wired in series with the hoist (H) and/or lower (L) contactor coils • Compare the positions labeled Hoist and Lower on the master switch MS contacts with the path through LSL • Notice whether any indicator light is actually connected to the LSL contact in this circuit

💭 Think About

• When the drum is being hoisted versus lowered, which contactor coil (H or L) must be energized, and does the current have to pass through LSL in that direction? • If the LSL contact were to open, would it merely change a light circuit or would it break the power path to a contactor coil and stop motion in one direction? • Which end of drum travel (near the boom or nearly all wire paid out) is normally protected by a "low" versus a "high" limit switch in hoist systems like this?

✅ Before You Answer

• Verify whether LSL is drawn as a normally closed contact in series with a contactor coil (H or L) rather than in parallel to a lamp • Confirm if there is any lamp symbol or separate indication circuit shown for LSL (or if it only lies in the control path to a motor contactor) • Determine whether the label LSL vs LSH suggests protection at the low or high cable position, and match that to the direction of drum rotation being limited
