The SQM40.../SQM41… and this Data Sheet are intended for use by OEMs which

integrate the actuators in their products!

Use

The SQM40.../SQM41... actuators are suited for driving oil pressure controller, butterfly

valves, dampers or for use on other applications that require rotary motion.

Areas of application are oil and gas burners of medium to higher capacity as well as

thermal process plants.

The actuators are used primarily for load-dependent control of the flow of gas, oil and

combustion air:

∂ In connection with modulating 3-position controllers or continuous controllers (e.g.,

4…20 mA) and/or…

∂ ... directly by burner controls

Mounting notes ∂ ∂ ∂ ∂ Β Ensure that the relevant national safety regulations and notes on standards are complied with In geographical areas where DIN regulations apply, the mounting and installation requirements of VDE must be satisfied, especially DIN/VDE 0100, 0550 and DIN/VDE 0722 Make certain that the actuator is not exposed to direct solar radiation Required tightening torques for the fixing screws of the - housing cover: 3.
PAGE 4
Electrical connection ∂ ∂ ∂ Β The actuators must always be powered via a prefuse of max. 6.3 AT (as per DIN EN 6012- 2/5) For the protective earth connection, the housing of all variants has a marked PE connecting terminal. A tightening torque of 1.2 Nm must be observed for fitting the screw The supplied RAST3.5 connectors or RAST5 connectors must be used with screw terminals for electrical connections. A tightening torque of 0.
PAGE 5
Cam settings The mechanical setting facility for the cams is physically separated from the connection terminals. When the actuator is disconnected from power, the switches can be adjusted via a scale. The cams can be changed via adjusting screws. The scale indicates the angles of the switching points.
PAGE 6
Lifetime The actuator has a designed lifetime* of 250,000 start cycles (close  open  close) under load with the rated torque in the entire rotation angle range, which under normal operating conditions in heating mode corresponds to approx. 10 years of usage (starting from the date of manufacture on the device type plate). This lifetime is based on the endurance tests specified in standard EN 298.
