Siemens Acvatix SQS65 Actuator

[Gary S]

Is there an adjustment on these actuators to reverse the direction? i have no info on this valve as im not installing it new. it has only 3 connections. 24v positive and negative and connection for 0 - 10V dc. It is installed on a 3 port valve for heating coil on a AHU.
at the moment when it drives to position 0 it is on full heat where it should be in bypass mode i think. i know a bms engineer would be able to change whether 0vdc is full heat or bypass but if i can do it without calling one out would be handy.
thanks in advance

yep theres a lil rotary changeover switch to set the rotation

where mate? i was there this evening and couldnt see it anywhere

its been modified since i last replaced them, the 0-10v dc signal connects on either y1 or y2 depending on direction req

[Gary S]

yeah the one i have is different G is 24v positive, GO is 24v negative and Y is the 0-10vdc. then theres R M and U. these are not connected. think R is 0-1000 ohms.

dont think there is rotation on a 3 port valve actuator- stem down is 0vdc and 10vdc stem lifts for flow
damper actuators do have the direction switch- cant copy the data sheet for it as its secured

[Gary S]

no worries thanks anyway. maybe a bms engineer is required to sort it. dont think its been right for a long time
