SQN70... / SQN71... SQN74... / SQN75...

Actuators SQN7...for air dampers and control valves of oil or gas burners

Reversible electromotoric actuators with torques up to 2.5 Nm

• Run times: - SQN70... / SQN71...- SQN74... / SQN75...

4...30 s4...60 s

• Versions: - Clockwise or counterclockwise rotation- With integrated electronic modules- Choice of drive shafts

• With 2 end and 2...4 auxiliary switches, some with fine adjustment• Geartrain can be disengaged• SQN70... / SQN71... - With adapter for direct replacement of actuators

type SQN30... / SQN31...• SQN74... / SQN75... - Drive shafts, fixing holes and cable entries are

matched to the same type of actuator supplied byConectron or Berger

• Versions with UL listing for use in the U.S. and Canada

The SQN7... and this Data Sheet are intended for use by OEMs which integratethe actuators in their products!

Use

The SQN7... actuators are designed for driving air and gas dampers of oil or gas burn-ers of small to medium capacity and afford load-dependent control of the amount ofgas, oil or combustion air• in connection with single- or 2-wire control, or 3-position controllers, or• directly via the burner control

Warning notes

To avoid injury to persons, damage to property or the environment, the followingwarning notes should be observed!

Do not interfere with or modify the actuators!

• Before performing any wiring changes in the connection area of the actuator, com-pletely isolate the equipment from the mains supply (all-polar disconnection)

• Ensure protection against electric shock hazard by providing adequate protectionfor the terminals and by securing the housing cover

• Check to ensure that wiring is in an orderly state• Fall or shock can adversely affect the safety functions. Such units may not be put

into operation, even if they do not exhibit any damage

Mounting notes

• Ensure that the relevant national safety regulations are complied with

Installation notes

• Installation work must be carried out by qualified staff

Commissioning notes

• Commissioning work must be carried out by qualified staff• Prior to commissioning, ensure that wiring is in an orderly state

Norms and standards

Conformity to EEC directives- Electromagnetic compatibility EMC (immunity) 89 / 336 EEC- Low-voltage directive 73 / 23 EEC

Service notes

• Maintenance work must be carried out by qualified staff• Each time a unit has been replaced, check to ensure that wiring is in an orderly

state

Disposal notes

The actuator contains electrical and electronic components and may not be disposed oftogether with household waste.Local and currently valid legislation must be observed.

Mechanical design

- Made of impact-proof and heat-resistant plastic

Color: SQN70... / SQN71...: Geartrain housing dark-grey,cover light-grey

SQN74... / SQN75...: Completely black

- Reversible and locking-proof synchronous motor

- Drive shaft can be manually disengaged from geartrain and motor- Automatic reengagement

- By means of adjustable cams- Scales beside the cams indicate the angle of the switching point- Assignment of cams to the end and auxiliary switches is color-coded (refer to

«Connection diagrams»)- Some of the cam switches feature fine adjustment; they can be changed with a

standard screwdriver- The other cams can be adjusted manually or with the enclosed hook-spanner or

similar tool

- Internally:Scale at the beginning of the camshaft on the geartrain side

- Screw terminals

- Maintenance-free

- Made of black-finished steel- Ready fitted to the front of the geartrain- Different versions available

- Front of the geartrain is used as the mounting surface- Actuator is secured via through-holes

- Made of glass-fiber reinforced epoxy resin- Metalized through-holes

Function

The synchronous motor drives the drive shaft which carries the camshaft.

The camshaft actuates the end and auxiliary switches.Using the associated cam, the switching position of each end and auxiliary switch canbe adjusted within the working range.Some of the actuator versions are equipped with electronic modules that perform aux-iliary functions in connection with the end and auxiliary switches or with external de-vices, such as controllers (refer to «Connection diagrams»).The functions and technical data of both lines of actuators SQN70... / SQN71... andSQN74... / SQN75... are nearly identical.

Using an adapter (refer to «Accessories»), actuators type SQN30... and SQN31... canbe replaced by the SQN70... / SQN71... .

There are no mechanical modifications required.The different terminal assignments of the 2 types of actuators must be observed, how-ever.

The «Type summary» contains the SQN3... that can be replaced by SQN7...actuators.

The SQN30... and SQN31... listed in «Type summary»• refer to the SQN7... AC 230 V versions.

The respective SQN3... AC 110 V versions use the same type reference as theAC 230 V versions, with one exception: Type suffix ..A27.. is replaced by ..A17.. .

• are versions with no facility for fitting a potentiometer (refer to Data Sheet 7808)

with special functions for heat generation plant(refer to Data Sheet 7865)

3-position controller for OPEN / CLOSEpositioning pulses with neutral position inbetween (2-wire control).

«BV2» is not used. Air / gas ratio control isused instead.

This can be accomplished in the form of• a control damper «RV» that is rigidly

connected to the air damper, or• an air / gas ratio controller «GL» type

SKP70... (refer to Data Sheet 7651)that – if combined with safety shutoff –is used in place of «BV1» (shown inbroken lines)

Thermostat or similar with N.O. contact (single-wire control).

In heating systems where the air damper does not fully close in the case of burnerOFF, thermal uplift occurs in the flueways (boiler, stack), causing the boiler to cooldown rather quickly, thus giving rise to increased heat losses.

If, during the program sequence, a damper position switch is approached from bothsides, it is not actuated in the same damper position, due to the switching differential.To ensure that actuation takes place in the same position, the program sequencemakes certain the required damper position will be passed for a short period of time.

The prepurge rate of the heat generation system (boiler, stack, etc.) prior to establish-ment of the flame must be in compliance with country-specific regulations. As a generalrule, the prepurge rate with oil burners should be 3 times the volume of the heat gen-eration system, and with gas burners, 5 times that volume. But these are only guidevalues. The effective prepurge volume required depends primarily on the type of con-struction of the heat generation system and is entirely the responsibility of the manu-facturer of that system. If prepurging is selected for the low-fire position, the prepurgetime is to be appropriately extended (against prepurging for the nominal load) to attainthe required air volume.

• For supplementary connections on the burner controls, refer to the relevant Data Sheets

• For auxiliary switches with fine adjustment, refer to «Technical data»

• In the connection diagrams, the positions of the end and auxiliary switches I...VI in the actuator for theworking range are shown between 0° and the adjusted angular position of the cams, that is, in the start position
