Description:
Electromotoric actuator for use with air damper and control valve of oil or gas burners of small to medium capacity, or for load-dependent control of the fuel or combustion air volume:
- In connection with P-PI or PID controllers, such as the RWF40...
- Directly via the different types of burner controls, such as LOA..., LMO..., LMG..., or
- In connection with 1- or 2-wire control or 3-position controllers.
Function:
The synchronous motor drives the actuator’s shaft via the gear train. The attachedcamshaft actuates the end and auxiliary switches. The switching position of each endand auxiliary switch can be adjusted within its working range via the associated cam.Some of the actuator versions are equipped with electronic modules for auxiliary functionsin connection with the end and auxiliary switches or with external devices, such ascontrollers (refer to ?Connection diagrams?). The functions and technical data of bothlines of actuators SQN3... and SQN4... are nearly identical.
