8.4.3 Uncontrolled stop, EMERGENCY STOP category 0
Function
This function concerns the stop category 0 EMERGENCY STOP for an uncontrolled stop in
accordance with EN 60 204-1. The function enables the voltage to be isolated via the circuit
breaker. The motor coasts down.
The safety shutdown is based on a single circuit. Protection against wire breakage is assured
due to the use of circuit breakers with undervoltage release. The emergency stop button used
is forced.
The following markings have the function:
● Use of proven components
● Suitable for the intended use
● The occurrence of a fault can result in the loss of the safety function.
The probability of a fault occurring is reduced as far as possible by the use of forced contacts.
The use of a single circuit in conjunction with undervoltage release achieves compliance with
safety category 1 to EN 954-1.
