l

	
Applicable area adheres to IEC 721-3-3 (Regulation 721-3-3 by International Electro-technical Commission ) Grade 3K5








	
l

	
Environmental temperature: -5...+50°C








	
l

	
Valve inner medium temperature: +2...+130°C









	
l

	
Using installation fittings ASK30 can drive the following 4mm or 5.5mm turn valves: X3i..., WG45..., VXG45..., VXG46... and VVI51...









Function Three-position or ratio control signal


Revisable synchro motor adopts three-way control signals (SQS35 and SQS85) or ratio control signal DC 0...10V (SQS65 and SQS65.5) or DC 2...10V (SQS65.2) for driving. It makes corresponding valve way through anti-lock gear mechanism.







Three-position control of Terminal Y1or Y2:



	
l

	
Y1 has voltage: valve rod contracts and valve gate opens








	
l

	
Y2 has voltage: valve rod extends and valve gate closes








	
l

	
Y1 or Y2 has no voltage: valve rod keeps in current position












SQS65...       Flow Characteristics Selection


Repositioning connection S1 (under cap/under print circuit board) can change the flow characteristics of 5.5mm turn valve (from “equal proportion” to “linear”). In any case, flow characteristics relate to valve way.



	
l

	
S1 connecting A and C can produce equal-proportion flow characteristics (factory set), which is mainly used for heating application.








	
l

	
S1 connecting B and C can produce linear flow characteristics, which is mainly used for cooling application.








	
l

	
For automatic operation, S1 connecting A and C or connecting B and C mainly depends on necessary flow characteristic.

Notes:

	
It must adhere to regulations and requirements for personal and property safety at any time.


	
SQS65...

	
When using Actuator SQS65..., valves with Types VVG55..., VMP..., VVP... and VXP... must be connected onto “lin” for connectors of selected flow characteristics.


	  	
It must obey allowable temperature (see “Application” and “technical Data”). It must be illustrated in Facility Diagram if auxiliary switch is needed.















Installation





Direction


















	  	
Valve Installation Handbook is printed on the back of actuator. Accessory Guide is put in corresponding accessory package box.


	
Debugging

	
Connection and function is inspected when debugging, in addition, auxiliary or auxiliary switch are also inspected and set necessarily.













	


	



	 	 
	
Stroke《0》= valve door close

	
Stoke 《1》=valve door open













	  	
Manual Regulator: Manual regulator is rotated clockwise to close Siemens 5.5mm Stroke Valve (=0% stroke)


	  	  
	
SQS35.../SQS85...

	
The flow characteristics of these actuators are linear when connecting to Valves of Type No. VVG44..., VVI52... or VXG444...


	  	  
	
SQS65...

	
The flow characteristics of these actuators are equal-proportion (factory sets) by electrical assembly when connecting to Valves of Type No. VVG44..., VVI52... or VXG44.... The flow characteristics can turn to “linear” through relocating connectors.

Guarantee

	
Actuator Technical Date (Δpmax, ΔPs, leak rate, noise level and working life) apply to Siemens valves listed in matched “Compatibility” only.


	  	
Siemens neither guarantee nor promise if SQS... actuators are connected to third-party valve doors.


	
Maintain

	
When repairing valves: turn off pump and power source, turn off main stop valve on pipes, release pressure in pipes and cool it down completely. If necessary, electrical connection from terminal should be disconnected.


	  	  
	  	
Actuator must be installed correctly with valve door, then restarting can be done.
