Information
ZEUS with emergency stop provides the highest safety (Cat. 4/PLe) acc. to
EN ISO 13849-1 only with an application of an appropriate safety relay/PLC,
such as MOSAIC M1.
In a safety circuit, both contacts of the enabling switch have to be evaluated separately
(2-channel design). In this process, cross circuits and short circuits are identified by the
safety relay.
For the application and use that meet the requirements, a voltage supply with the attribute
SELV/PELV has to be used.
Danger of squeezing or cutting of the connection cable has to be eliminated by means of
appropriate measures:
• Protection of the cable by appropriate routing, e.g. in a protective hose.
• Cross-circuit monitoring with an evaluation device
• Use of cables with separately shielded wires. These shields have to be connected with
the protective conductor system of the machine or plant. Therewith the wiring short
circuits are detected and the control unit is immediately switched off by the activated
protection against short circuit.
The electrical connection should only be performed in a de-energized state by authorized skilled
personnel. After connection, remove debris such as cable residues from the contact element.
