Page 35: Normal Adjustment "V50
6.6.1 Normal adjustment "V50" EKM-0096 Fig. 16 Two cam discs are arranged for each contact, which are continuously adjustable. According to the position of the cam, the castor run can be doubled for a contact and the nominal travel shortened accordingly. The effective cam angle (5) and the usable angle of the cam disc (6) are illustrated in the figure. -
Page 36: Fine Adjustment "Fv50
6.6.2 Fine adjustment “FV50” EKM-0097 Fig. 17 Each contact is assigned to a cam disc group, consisting of an adjustable cam (6) and cam disc (7). The adjust- able cam (6) is connected via positive locking over a ring with toothing on both sides (2) to the switching shaft. While the worm’s (8) self-locking feature is enabled, the torque is transferred further by means of positive lock- ing from the adjustable cam (6) to the toothing of the cam disc (7). -
Page 37: Double Fine Adjustment "Dfv
6.6.3 Double fine adjustment "DFV" EKM-0098 Fig. 18 Two cam disc groups are assigned to each contact, consisting of adjustable cams (6) and cam discs (7). Each cam disc pair can be adjusted infinitely and used in a defined way from both sides. The effective cam angle (10) and the usable angle of the cam disc (11) are shown in the figure. -
Page 38: Normal Adjustment "V70
6.6.4 Normal adjustment "V70" EKM-0099 Fig. 19 Two cam discs are arranged for each contact, which are continuously adjustable. The cam discs (1) can be adjusted independently of one another after loosening the nut (3). The locking plate (2) as well as the inner ring (4) thereby prevent the adjustment of a previously adjusted cam disc by adjusting the next disc. -
Page 39: Block Adjustment "Bv
A cam disc group is assigned to each contact, consisting of a cam disc (1), adjustable cam (2), adjustment worm (3) and tooth ring (4). The adjustable cam (2) is connected to the switching shaft by means of positive locking via a tooth ring (4). The adjustment worm (3) with a self-locking feature transfers the torque further by means of positive locking from the adjustable cam (2) to the toothing of the cam disc (1). -
