Emergency Stop
The supply disconnecting device may serve as an emergency stop when it is readily accessible to the operator and it is of the type described in EN 60204-1:2006, 5.3.2 a), b), c) or d). When intended for such use, the supply disconnecting device shall be colored red and have a yellow background. (Ref. EN 60204-1:2006, 10.7.5).
The POWER FOCUS 6000 provides an infrastructure to build an Emergency Stop function with redundant breaking according to EN ISO 13849-1 category 3 PL d. The Emergency Stop function must be used when using remote start functionality.
The Emergency Stop functionality can be used with a supply-disconnecting device (such as an Emergency Stop button). When the Emergency Stop button is activated, it breaks the supply voltage to the controller.
A diagnose of the system is run automatically at the start of the controller. This is done both after an emergency stop and at a normal start.
The Emergency Stop function is used with either a single controller or up to 10 controllers in a single emergency stop chain. In a multiple controller configuration, the Emergency Stop signal is distributed from the first controller to all interconnected controllers using the I/O bus interface. The last controller in the chain returns a feedback signal to indicate that all controllers have received the Emergency Stop signal. The event Emergency Stop is displayed.
For the Emergency Stop there is a 24V DC output through the Emergency Stop interface on the connector panel.
