Safety instructions
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.
Ä
In the event of a fault, put out of operation
In the event of malfunctions and visible damage, put the control unit out of
operation by decommissioning it.
Ä
Prevent the machine from restarting
Prevent the machine from restarting while a hazard exists, e.g. by using a
starting lockout.
Ä
Avoid electric shocks
Before working on electrical systems, disconnect them from the power supply
and secure them to prevent them being switched back on to avoid electrical
injuries.
For your
own safety
, you must adhere to the following safety instructions.
Ä
Take care when setting up the interface
Overall safety is affected by the quality and reliability of the interface between
the protection device and the machine. Take particular care when setting up
the interface.
The control unit is designed for processing the signals of a pressure-sensitive pro-
tection device (PSPD). It evaluates the output signals of sensors with monitoring
resistor 8k2 or 10k. The integrated output signal switching devices (OSSDs) trans-
mit the evaluated safety signals directly to the downstream control.
The product complies with ISO 13849-1:2015 category 3 PL d. To prevent any re-
duction in the safety classification, the downstream control must be of the same
category or higher.
The product has been developed taking EN 50155 into consideration and is suita-
ble for rail applications.
