APPLICATION

The LKS 131 air damper actuator is designed to be fitted to

multi-stage or modulating oil and gas burners with fully

closed position.

EN2C-0111SZ20 R0202 2

A synchronous motor powers an output shaft and a backlash-

free cam shaft via a gear reducer.

The cam shaft operates limit and auxiliary switches. The

GENERAL

Electric actuator up to 0.6 Nm

• Drive times: 3 ... 38 sec.

• Variants: - clockwise or counter clockwise rotation

- with integrated electronic circuitry

- shaft version

DESCRIPTION

position at which one of the limit or auxiliary switches operates

can be adjusted steplessly within the operating range using

the associated cam disc. Spindle-driven cams, which can be

adjusted with a screwdriver, are available.

FEATURES

• Internal position indicator

• Easily adjustable limit and auxiliary switches

• Synchronous motor

• The regulations and standards applicable in each

particular case must be observed.

• Installation and commissioning must only be

carried out by qualified technicians.

• Electrical wiring must comply with national and

local regulations.

• Always lay the burner ignition cable separately

and as remotely as possible from the device and

other cables.

• Carefully check all cabling and wiring prior to

commissioning.

• Disconnect the actuators completely from the

power supply when working close to terminals

and connections.

• Screw the housing cover securely in place to

provide shock-hazard protection on the actuator

and all electrical connections.

• Electromagnetic emissions must be checked on

a case by case basis.
