Adjustment of one safety trip point

Essential conditions:

- The hook of the lifting system should be free of any load.
Equipment required:
A load ("Pm") equivalent to 100 % of the working load limit of the lifting system.
-
- An additional load equivalent to 10 % of « Pm ».
ACTIONS
Lift the two loads (100 % + 10 %
1
WLL) by about 10 cm.
2 Adjust the safety threshold S1.
3 Check correct operation.
REMARKS
The additional 10 % represents the overshoot value
authorized in accordance with the European
directives.
Gradually screw in the threshold adjustment screws
(§ 2.1, rep. G) until the NC contact opens (see § 3.1).
Use an ohmmeter, for example, to check the state of
the contact.
It must be possible to lift the "WLL" load.
It must be possible to lift the "WLL" load + 10 %.
Depending on the lifting speed, the dynamic effect
may produce an unintentional overload. In this case,
consult with a technician capable of integrating a
signal filtering device (example: time-out, etc.).
