The setting up of the safety switch on the overspeed governor is not necessary.
3.2 TENSION WEIGHT WITH COUNTERWEIGHT (EN 81)
a) guide rail mounted tension pulley with horizontal or vertical counterweight:
• shift the mounting clamp of the tension weight with counterweight in such a way that the safety switch does
not become operative (Fig. 1 and Fig.2, Pos. 1).
At the same time take into consideration the stretching of the rope!
On the safety switch adjust the connecting position on the slots in the vertical direction
●
(Fig.1 and Fig.2, Pos.2).
