Task:
Emergency Stop with monitored Start and Protective Door with automatic start according to category 4 in EN 954-1. (with evaluation as per EN 62061 and EN ISO 13849-1: 2006) with MSS Basic

Solution:
 

In this Safety Function Example, the emergency stop command unit is monitored through the modular safety system 3RK3. When the emergency stop is actuated, the safety switching device switches off the positively driven downstream contactors Q1 and Q2 via the safe outputs according to stop category 0 as defined in EN 60204-1.
Before renewed switch-on or acknowledgement of the emergency stop device via the start button, a check is carried out to monitor whether the contacts of the emergency stop control unit are closed and both contactors are switched off.
The protective door is also monitored by a SIRIUS position switch through the MSS. When this protective door is opened, the safety switching device switches off the positively driven downstream contactors Q1 and Q2 via the safety-oriented outputs according to stop category 0 as defined in EN 60204-1. When the protective door is closed, an automatic start takes place after the position switch and the downstream contactors have been checked.
