Emergency Stop

Not fully functional emergency stop devices may have fatal consequences!
Emergency stop switches which are red-yellow marked must be effective under
all circumstances in all operating modes of a machine or plant.

The emergency stop switch used on the M70 features two circuits. The contacts
are normally closed.

The emergency stop switch of the M70 meets the requirements of the EN 418.
It must be designed as an emergency stop of category 0 or category 1 (see EN
60204-1) on the basis of the risk assessment for the machine. The connection of
the positive-break contacts to an appropriate monitoring system must meet the
safety category which is defined by means of the risk assessment (in accordance
with EN 954-1) of the machine.
