 Versions: – Choice of drive shafts (refer to «Type summary»)

The actuators SQM45... / SQM48... and this Data sheet are intended for use by

OEMs which integrate the actuators in their products!

Use

The SQM45 / SQM48 actuators are suited for driving oil pressure controllers, butterfly

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

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

as thermal process plants.

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

volume and combustion air volume in connection with the electronic ratio control LMV5.

Mounting notes      Ensure that the relevant national safety regulations and notes on standards are complied with In the geographical areas where DIN regulations are in use, the requirements of VDE must be complied with, 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.

Mounting notes (cont´d) IP54 To ensure degree of protection IP54, suitable M16 glands must be fitted in the actuator’s M16 openings. The M16 glands used must feature cable strain relief. To ensure degree of protection IP54 during the actuator’s entire service life, the bearing of the drive shaft must be located such that it will not be directly exposed to water or dust. Mounting example Spacer Mounting plate SQM45... Mounting plate VKF41...

Installation notes       Ensure that the electrical wiring is in compliance with national and local regulations. Make certain that strain relief of the connected cables is in compliance with the relevant standards (e.g. as per DIN EN 60730 and DIN EN 60335) Ensure that spliced wires cannot come into contact with neighboring terminals.

Lifetime The actuator has a designed lifetime* of 250,000 start cycles (OFF  ON  OFF) 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 service (starting from the production date given on the nameplate). This is based on the endurance tests specified in the standard EN 298. A summary of the conditions has been published by the European Control Manufacturers Association (Afecor) (www.afecor.org).

Terminating resistor At the end of the serial bus cabling, a terminating resistor must be fitted. For that purpose, a jumper must be set to BUS TERMINATION on the last actuator of the bus cable, which will activate the resistor. On all the other actuators, that jumper must be set to the other position (deactivated).
