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.3.
4.1 Adjustment of torque unit
In the production plant switching-off torque for
both the "opening" direction (the torque switch S1, or
S11) as well as for the "closing" direction (the torque
switch S2, or S22 ) are adjusted to specified value
±10%. 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.4)
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. 4):
• 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" is to be end 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) counter-clockwisely 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)
counter-clockwisely 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 signaling cams are set next
to the limit positions. The signal possibility is available
along the whole operation angle in both directions, i.e.
100%.
