According to function they are the following:
– Torque tripping unit 1
– Limit tripping unit 2
– Signalling unit 3
These units are universal for all sizes of the actuators are mounted on a common base plate 4.
Description and function of control units
a) Torque tripping unit
(Fig. 3)
as an independent assembly unit, it consists of base plate 19, which carried micro
switches 20 and at the same time creates bearings for torque control shaft 22 and locking shaft 29. Torque control shaft
transfers motion of the floating worm from power gear, using segments 23 or 24 and handles 45 or 46, to micro switches.
Tripping torque value is adjusted by rotating the segments against the tripping handles. For possible tripping torque
set-up outside the manufacturing plant, segments 23 and 24 are provided with a scale providing individually for each
actuator indications of points for setting up the maximum and minimum torque. The set up torque is indicated by recesses
in segments 27 and 28. Figures on the scale do not give direct indication of the tripping torque. Increments on the scale
only serve to provide a more accurate division between the maximum and minimum torque levels, and thus to enable
a more precise set-up of the tripping torque outside the manufacturing plant if no loading bench is available. Segment
23 is intended for “closing” direction, segment 24 for “opening” direction.
