UP 0, UP 1, UP 2, UP 2.4, UP 2.5 23
Adjustment and setting of the torque unit for EA UP 2, UP 2.4, UP 2.5 actuator to alternative torque values is
possible through the use of adjustment segments according to Fig. 2a . Torque can be reduced by releasing the
screw and sliding the graduated segment along the gauge mark on the arm of the torque unit.
Adjustment towards M results in resetting the switching-off torque to maximum value. Adjustment towards 0
results in reduction of the switching-off torque.
4.2 Adjustment of position-signalling unit
UP 1, UP 2, UP 2.4, UP 2.5 (Fig.3):
By default the actuator is set by the manufacturer to standard stroke (according to specification), as specified in
the nameplate.
While setting, adjusting and resetting follow these steps (Fig. 3):
•
in the version with a resistant transmitter (Fig.4) disengage the transmitter;
•
loosen the nut (22) with simultaneous holding the central milled nut (23) and then loosen the nut (23) fixing
the cams still having the belleville springs which create axial thrust;
•
reset the EA to the “Open” position and rotate the cam (29) clockwise (when viewing the actuating plate
from above) until switch S3 switches over (25);
•
reset the EA by the angle where the “Open” position is to be indicated and turn the cam (31) clock-wise until
switch S3 switches over (27);
•
reset the EA to the “Closed” position and turn the cam (28) counter clockwise until switch S4 switches over
(24);
•
reset the EA back by the angle where the “Closed” position is to be indicated and turn the cam (30) counter
clockwise until switch S6 switches over (26);
•
once the EA is adjusted manually tighten the central milled nut (23) to lock the cams and tighten the lock nut
(22) while simultaneous holding the milled nut;
•
swing the position indicator discs (32) for the given operating stroke against the gauge mark on the top
cover sight;
•
once of the position- signalling unit is adjusted also adjust the position transmitter or converter.
There is an option of bi-directional signalling at all operating stroke time, i.e. 100 %.
