Intended use

The control unit is designed for signal processing of a pressure-sensitive protective
device. It evaluates the output signals of sensors with monitoring resistor 8k2. The
integrated output signal switching device (OSSD) transmits the evaluated safety sig­nals directly to the downstream control.
The product complies with ISO13849-1:2015 Category 3 PLe. So that the
safety classification is retained, the downstream control must be of the same or a
higher category.

Safety instructions

For your own safety the following safety instructions apply.

Ä Prevent electric shock

When working on electrical systems, always disconnect them from the power
supply and secure them against being switched on again, to prevent injuries from
electric shock.

Ä Ensure careful configuration of interface

The quality and reliability of the interface between the safety device and the ma­chine aects the overall safety. Take special care when setting up this interface.

Ä Prevent restarting of the machine

As long as a hazard continues to exist, take measures to prevent the machine
from restarting, for example by means of a startup lockout.

Ä Disable in case of error

Disable the safety device in case of malfunctions or visible damage.

Ä Do not use in ATEX zones

Do not use the Control Unit in potentially explosive environments (ATEX). The
control unit is not authorised for use in these zones.

To prevent irreparable damage to the product, the following safety instructions ap­ply.

Ä Do not open the control unit

Never open, tamper with or alter the control unit.

Ä Observe degree of protection

Only use the control unit in rooms with a minimum degree of protection of IP54
(e.g. switch cabinet).
