2. SAFETY

Intended use

HD5-B-xxx is a three-position enabling device with integrated AS-i technology, according to the AS-i
specification V 3.0, it is operated in the standard addressing mode. (see chapter "AS-i data")
The device is intended for connection to an AS-i safety bus and connected to a suitable safety controller.
Additionally, the machinery or the equipment causing the potential danger needs to be put in jog position
or otherwise restricted in movement, speed, temperature, etc.
The operator pushes the large black button to a middle position in order to allow a movement. In case of
danger, the operator will either release the button or squeeze it to its bottom position and the machine will
stop. Some models offer additional top and front buttons to control a non-safe signal, e.g. move forward
and/or backward.

Correct use

The protective function of the safety device is only safe if the safety controller is correctly connected and
configured.
Obey the following conditions to prevent misuse and cause danger:

Make sure that these instructions are included together with the documentation of the system to which
the protective device is attached to.

Make sure that these instructions always are available for the operators.

The three-position device must only be used after it has been selected refereed to related instructions,
relevant standards, rules and regulations for labor protection and safety at work, and when installation,
connection, check and start-up are done by an approved person.

The three-position device must be connected and started according to its specifications, for example
the technical data.

The three-position device must be connected so that its safety related capacity meets or exceed the
performance level (PL) or safety integrity level (SIL) that has been estimated in the risk analysis.

The three-position device must not be modified. If the design or the functions are changed the
protective function can be damaged and the warranty of the three-position device is not applicable.

Repair and exchange of parts of the three-position device is not permitted.

The three-position device must be tested regularly by an approved person.

The three-position device must be exchanged within a mission time 20 years, due to requirement in EN
ISO 13849-1. Depending on the use (calculation of T
three-position device might have to be exchanged within a shorter time than 20 years.
