Safety

2.1

Intended use

The intended use of the Sentry safety relay is to monitor the state of a safety device and
depending on the state, activate or inactivate the outputs within the system response time.
The protective function of the safety device is only safe if the safety relay is correctly
connected and configured. The safety relay is not by itself a complete protective device.

• Use the safety relay as a safety monitoring device.

• Use the safety relay as expansion device of safe outputs

• The safety relay is not intended for use in explosive or easily flammable adjacent air.

• Other use than defined as correct is considered as incorrect use.

2.2

Safety precautions

Warning!

The safety precautions must be followed during installation, operation,
maintenance and troubleshooting.

Warning!

The safety functions must be tested at start up or at replacement
before the system is put in operation.

Installation shall be conducted by authorized personnel following the Safety regulations,
standards and local legal regulations. Carefully read through the entire original instruction
before using the device.

Make sure that these instructions are included together with the documentation of the
system. Make sure that these instructions always are available for users of the system.

The safety relay must be selected so 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 safety relay must only be used after it has been selected according to related
instructions, relevant standards, rules and regulations for protection and safety at work.

The entire dangerous zone must be visible from the position where the reset button is
installed. The reset button must be positioned out of reach from the dangerous zone.

The safety functions must be tested after installation or replacement of components or
cables. The safety relay must be exchanged within 20 years.

Failure to comply with instructions, operation that is not in accordance with the use
prescribed in the instructions, improper installation or handling can affect the safety of people
and the system. Failure to comply with the instructions or standards, excludes any liability.
