18 Servomotor type SQM 5...
Electromotoric actuator for air and gas dampers
The actuators SQM... are designed to drive air and gas dampers for load-independent regulation of fuel
and combustion air flow, e.g. directly by way of various automatic firing sequence controllers.
NOTICE:
For more information please see Siemens datasheet 7851 in the appendix.
18.1 Function
A synchronous motor drives a drive shaft with fitted cam roller by way of a gear box. The cam roller actuates
limit and auxiliary switches. The switching position of each limit or auxiliary switch can be configured by
way of an associated cam disk within its movement range.
The Axis can be disconnected from gear box and motor by way of manual actuation of a coupling with lock-
ing pin (10) and (11).
