SETTING UP OPERATIONS

3.1

OVERSPEED GOVERNOR

The safety switch of the overspeed governor has already been set in the factory. Its position is fixed with sea-
ling-wax and it cannot be modified.
The setting up of the safety switch on the overspeed governor is not necessary.
3.2

TENSION WEIGHT WITH COUNTERWEIGHT (EN 81 and TRA)

Only in plants in conformity to EN 81:
a) with tension pulley with horizontal 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, pos. 1).
At the same time take into consideration the stretching of the rope!
• On the safety switch, adjust the horizontal connecting position on the slots (fig. 1, pos. 2).
• After the assembly, release the tension rope and check the control function by moving the tension arm. Then
fix the position with sealing-wax or similar.
• After the insertion, the tripping pin of the safety switch must be reset by hand in the starting position.
b) with tension pulley with vertical counterweight:
• Move the mounting plate of the safety switch in the vertical direction (fig. 2 – pos. 1) in such a way that the
switch does not activate.
• On the switch, adjust the horizontal connecting position on the slots (fig.2 – Pos. 2).
• After the assembly, release the overspeed governor rope and check the control function by moving the coun-
terweight slowly downwards on the guide rail and paying close attention. Then fix the position with sealing
wax or similar.
• Following the insertion, the tripping pin of the safety switch must be reset in the starting position.
