4.8.1 Adjusting of backstop screws during switching-off the EA from position unit
If EA is equipped with torque switches thus these fulfill the function of limit switches in case when EA
is not switched-off from the position unit switches, eventually they fulfill also protective function against
overloading of EA.
Procedure:
•
release both backstop screws in such way that their heads shall be on the same level as the
opening edge (Fig.13)
•
readjust the EA into position „Z“ (“closed”) until disconnection of the position switch
•
rotate the backstop screw to the right until you feel increased resistance when bumped the
backstop. Under such achieved status turn the screw by 1/2 rotation backwards as minimum to
avoid sooner connection from the torque unit,
•
perform similar adjustment of the backstop screw for position "O" (“open”).
4.8.2 Adjusting of backstop screws during switching-off the EA from torque
When using the backstop screws as endpoints (backstops) for the EA output shaft path thus the
EA must have the torque unit adjusted in such way that no overrunning of the switching-off torque could occur.
Procedure:
•
by means of manual wheel readjust the EA into position "Z" (“closed”),
•
release both backstop screws in such way that their heads shall be on the same level as the opening edge
(Fig.13)
•
rotate the backstop screw for position "Z" (“closed”) to the right until you feel increased resistance when
bumped the backstop
Adjustment of stroke 90° - with changed position of operating angle +10° in direction „O“ (open)
