Application Proposals for Hardware-Based Safety Functions
How to Implement the Safe Stop Category 1 (SS1)
Refer to the schematic EL-1122-05-xx: Inverter Enable circuit Lexium 62 Connection Module / Lexium 62 ILM using the Logic Motion Controller LMC•00C with safety switch device for an emergency stop circuit.
NOTE:
-
All application proposals provide for a protected Inverter Enable-wiring (control cabinet IP54) from the safety-related switch device to the Lexium 62 Connection Module, as wiring issues need to be ruled out.
-
Protection against automatic restart must be provided by the external safety-related switch device.
NOTE: The mains contactor in the circuit suggestion EL-1122-05-xx is not necessary for functional safety purposes. It is, however, used in the application proposal for the device protection of the Lexium 62 Power Supply or the components connected to it.
