Operating Instructions for Rope Pull

When installing and adjusting the rope pull switch, it is necessary to take into account the physical changes in
the rope length as a result of variations in temperature.
Table 3 shows the permitted rope tension lengths as a function of the expected temperature difference.
The diagram also shows the maximum permitted rope tension length for the different spring forces of the
respective switch types. It also permits selection of the appropriate switch corresponding to the expected
temperature variations.
