Intended use
The GCLS is exclusively intended for use in industrial areas and must only be used to open electrical circuits
through the positive locking entrainment of a driven shaft. Geared cam limit switches of type series 51 (GCLS) are
universal, mechanical switchgear that show a maximum number of shaft revolutions to the angle of rotation of the
installed cam disc. Mechanical contacts are actuated by these cam discs.
The GCLS may only be operated with the correctly-installed and functioning IP protection classes.
2.3.1
Application limits
The application limits are defined in the technical specifications, see section 4.1. The GCLS must not be used in
potentially explosive areas.
2.3.2
Approvals
Overview of the respective national and international approvals of the GCLS, see section 4.1.8.
2.4
Foreseeable misuse
Engaging the contacts using elements other than the cam discs (e.g. screw drivers, wires, etc.) can cause
damage.
2.5
Non-intended use
Any use other than the intended use of the GCLS may lead to dangerous situations.
•
Only use the GCLS for its intended use in accordance with the details in this documentation, especially in
observing the application limits given in the technical specifications.
•
Reconstruction, retrofitting or modification of the construction or individual equipment parts, with the aim of
changing the application range or the usability of the GCLS, should be avoided.
