Honeywell LKS310-21 (A5D-30S12) actuator

The Conectron LKS310-21 (A5D-30S12) servo motor is designed for use in multistage or modulating oil and gas burners with a fully closed position. This Honeywell 78-LKS310-21U servomotor is equipped with an output shaft for an asynchronous motor and a backlash-free camshaft controlled by a gear reducer.

The camshaft controls the limit switches and auxiliary switches. The position at which one of the switches is activated can be steplessly adjusted within the operating range using a special camdisc disc. For this purpose, there are manually adjustable cams controlled by a lever, as well as spindle-driven cams adjustable with a screwdriver.
