LKS 310 Actuator for air dampers on multi-stage and modulating burners
2 www.honeywell.com
DESCRIPTION
A synchronous motor powers an output shaft and a backlashfree
cam shaft via a gear reducer.
The cam shaft operates limit and auxiliary switches. The position
at which one of the limit or auxiliary switches operates can be ad-
justed steplessly within the operating range using the associated
cam disc. Manually adjustable lever-operated cams or spindle-
driven cams, which can be adjusted with a screwdriver, are avail-
able.
FEATURES
Electric actuator up to 15 Nm
• Drive times: 3.5 ... 30 sec.
• Gearing can be decoupled
• Position indicator
• Easily adjustable limit and auxiliary switches
• Synchronous motor
• Particulary stable design in aluminium housing
Variants:
• clockwise or counter clockwise rotation
• with integrated electronic circuitry
• different shaft versions

INSTALLATION
Safety Guidelines
1.Screw the housing cover securely in place to provide shock-
hazard protection on the actuator and all electrical connec-
tions.
2. Always lay the burner ignition cable separately and as remotely
as possible from the device and other cables.
3.Electromagnetic emissions must be checked on a case by
case basis.
COMMISSIONING AND INSPECTION
Safety Guidelines
Function control
For safety reasons the actuator should be tested on commission-
ing the installation as well as after a service or longer shut-down.
REPAIRING AND DISPOSAL
WARNING
• The regulations and standards applicable in each
particular case must be observed.
• Installation must only be carried out by qualified
technicians.
• Electrical wiring must comply with national and local
regulations.
• Disconnect the actuators completely from the
power supply when working close to terminals
and connections.
WARNING
• Commissioning and inspection may only be carried
out by qualified personnel.
• Carefully check all cabling and wiring prior to com-
missioning.
It is forbidden to do any repairing on actuator
LKS 310.
The distributor of the heating system assures the pro-
fessional disposol or the forwarding to the manufac-
turer for inspection.
