4. Adjusting of actuator
Abide by safety measures!
After mechanical connection, electrical connection and
checking of connection and function start setting and
adjustment of the device. The adjustment can be
performed at a mechanically and electrically connected
EA. This part describes adjustment of EA to specified
parameters in case that any unit of EA is reset. Laying
of adjusters of the control board is shown on Fig. 2
4.1 Adjustment of torque unit
In the production plant switching-off torque for both the "opening" direction (the torque switch
S1) as well as for the "closing" direction (the torque switch S2) are adjusted to specified value ±15%. If
not agreed else they are adjusted to maximum value.
Adjustment and setting of the torque unit to other values without any testing device for torque
measuring is not possible.
4.2 Adjustment of position-indicating unit (Fig.3)
The EA are in the production plant adjusted to a fixed
angle (according to the specification), given on the
nameplate. While setting, adjusting and resetting follow
these steps (Fig. 3):
•
In the version with a transmitter put the transmitter out of
mesh.
•
Loosen the nuts (23) fixing cams still having the Belleville
spring creating axial pressure.
•
Put the EA to the position "open" and turn the cam (29)
clockwisely until the switch S3 (25) switches.
•
Change setting of the EA by the angle, where the
position "open" is to be indicated and turn the cam (31)
clockwisely until the switch S5 (27) switches.
•
Put the EA to the position "closed" and turn the cam (28)
counterclockwisely until the switch S4 (24) switches.
•
Turn the EA back by the angle, where the position "closed" is to be indicated and turn the cam (30)
counterclockwisely until the switch S6 (26) switches.
•
Having the EA adjusted lock the cams with the central milled nut and counter-nut (23).
If not agreed else the signalling cams are set next to the limit positions. The signal possibility is
available along the whole operation angle in both directions, i.e. 100%.
