4. Set up
Attention!
See article 1.2.
Switch OFF the electric actuator from electric power line!
Adhere to safety regulations!
EA is from production plant set up to fixed value of working revolutions S (stated by customer
in the order). If you want to set up EA to other parameters, proceed according to following instructions.
Set up is performed on mechanically and electrically connected electric actuator. In this chapter is
described set up of electric actuator to parameters specified in specification table in case if you need
to change preset parameters of electric actuator. Displacement of adjusting elements of control board
is in pic. 3, respectively in pic. 4.
4.1 Set up of transmission unit (pic. 5)
4.1.1 Stage set up
The gearbox of transmission unit is necessary to adjust into two stages (see table 2).
Individual stages are geared into mesh by shifting toothed wheel (43), which is faste-ned onto
output shaft (48) by the pin (50). After adjustment of required stage and securing of shifting wheel is
put on the upper front of a gearbox (49) with input wheel (12) and is secured by locking washers (47).

4.1.2 Set up of subscale
For set up of relevant subscale according to Table 2 is used the magnitude of curve rising “a“
(short curve), respectively “b“ (long curve).

The growth of circulant based on the angle, must be clockwise from the sight of eccen-tric.
Should set up curve is unsufficient; unscrew the nuts (41) pic. 3, respectively pic. 4, thus allowing
access to gearbox fastening bolts, remove securing ringlet (52) pic.5 and washer (61) and eccentric
(15) turn the other side. During repeated securing by securing ringlet you will have to overcome the
force of flat spring, which in connection with other parts forms friction securing clutch of transmission
unit.
Example:
EA MO 3.5 with 10 working revolutions (II. stage, curve “b“) should be set up to stroke of 15 working
revolutions (III. stage, curve “a“).
