1.Generally
1.1Purpose and application oftheproduct
Electricmultispeed actuators(hereafterreferred toas EA),types MO3.3,MO3.4resp.MO3.5 are
highperformanceelectro-mechanicalproducts, designed fordirect assemblyon controlled devices(wedge-
typeand apron slide controllersand otherequipments). EA aredesigned forremotecontrolofarmaturesby
reversingrotarymotion inbothdirectionsoftheirmovement. Theyareequipped bymeasuringand
technologicalprocessescontrollingmeans;the information carrieron theirinputand/oroutputisunified
analogue directcurrent, orvoltagesignal.Theycan beused inheating,energy,gas,air-conditioningand
othertechnologicalequipments,forwhicharesuitabledue totheirmanufacturingqualities.Theyare
assembled bymeansofflangeand connectingcomponentinaccordancewithISO5210,DIN3338,orin
accordancewithOST26-07-763.
1.It isprohibited touseEA aslifting device!
2.The option ofswitching EA via semi-conductivetriggerswitchesmustbe consulted withthe
actuatormanufacturer.

· The camsforsignaling are, until otherwiseagreed, set up justinfrontofterminalposi-tions.The
possibilityofsignalization isthroughout wholeworking angleinbothdirections, i.e. 100 %.
4.3Setup ofresistive transmitter
ResetEA toposition “closed“.Turnthe toothed disk (13)(pic.4,5)clockwisebyscrew-driver.
Thuswill be achieved turning ofeccentric(15),along the curveofwhichisshif-ted the backstop ofthe

Attention:
The backstop ofshifter(27)mustnotduring turning ofeccentric(15)pass through the top ofeccentric.In
thatcasewould the senseofresistivetransmitterrotation be reversed and the range oftransmission unitsetup
would be changed, in connection withtransition fromone eccentriccurvetoanother.
