Mounting multi-turn actuators SA/SAR
Mounting the multi-turn actuator:
.
Thoroughly degrease the faces of the bearing flange at actuator and of
the input flange at spur gearbox.
.
Place the multi-turn actuator on the spur gearbox.
.
Ensure that the spigot mates uniformly in the recess and that the
mounting faces are in complete contact.
.
Fasten actuator with screws (see table 1) at the flange of the spur
gearbox.
.
Fasten screws crosswise with a torque according to table 2.
Do not attach ropes or hooks for the purpose of lifting the
actuator by hoist to the handwheel. If multi-turn actuator is
mounted on gearbox, attach ropes or hooks for the purpose
of lifting by hoist to gearbox and not to multi-turn actuator.
