1 Introduction

1.1 About this documentation

Stromag GmbH strongly emphasises that the technical details such as dimensions, weights in kg, tolerances,

tightening torques and units required for assembly, such as securing means and lubricants, must be obtained

from the dimensional drawing.

Should this information be necessary during assembly, a corresponding point in these mounting/operating

instructions will be referenced on the dimensional drawing.

A dimensional drawing is supplied as a separate document and can be requested additionally from our aftersales

services, see section 11.2. For this, the information on ordering spare parts is required, see section 11.1.

For the purpose of simplification, the following designations are used in the mounting/operating instructions.

•Mounting/operating instructions will be referred to as Documentation in the following.

•The gear limit switch, type series 51, will be referred to as GCLS in the following.

This documentation makes it easier for the operator to familiarise himself with the GCLS and to use it for its

intended application.

This documentation covers various GCLS designs. The figures used are partly by way of example only. The

specific design of the supplied GCLS is shown in the dimensional drawing, see section 4.2.

The documentation contains important instructions on how to operate the GCLS safely, properly and

economically. Observing the documentation helps to avoid dangers, to reduce repair costs and down times and to

increase the reliability as well as the operating life of the GCLS. Read the documentation carefully and thoroughly.

1.1.1 Target group

The documentation is limited to use by qualified as well as trained personnel.

The documentation must be read and applied by every person that is assigned with performing at least one of the

following tasks:

•transport

•assembly,

•use,

•maintenance and inspections,

•troubleshooting,

•disassembly

•disposal of operating and auxiliary materials

1.1.2 Use/storage

This documentation must always be kept to hand at the operation location of the GCLS. The documentation must

then be integrated into the overall documentation of the machine and into the safety concept. When selling the

GCLS, the documentation must also be passed on.

2.2 Required personnel qualifications

The following table shows the qualifications specified for the different tasks.

•Only employ qualified or trained personnel.

•Do not authorise people whose ability to react is impaired, for example by the influence of drugs, alcohol,

medication or similar. Observe the specific national age guidelines.

•Observe all other nationally-applicable guidelines of the respective country of use.

2.3 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
