Honeywell LKS310-15 (A5D-30S1) actuator

The Honeywell LKS310-15 (A5D-30S1) actuator is designed for use in multistage or modulating oil and gas burners with a fully closed position. The Conectron 78-LKS310-15U servomotor is equipped with an output shaft for asynchronous motor power and a backlash-free camshaft, which is controlled by a gear reducer. The camshaft controls the limit and auxiliary switches. The position at which one of the switches is triggered can be steplessly adjusted within the operating range using a special camdisc disc. For this purpose, manually adjustable lever-operated cams are available, as well as spindle-driven cams that are adjustable with a screwdriver.
