} Dual-channel operation without detection of shorts across contacts: Redundant input
circuit, detects PNOZ X10.11P
– earth faults in the start and input circuit,
– short circuits in the input circuit.
} Automatic start: Unit is active once the input circuit has been closed.
} Manual start: Unit is active once the input circuit and the start circuit are closed.
} Monitored start: Unit is active once
– the input circuit is closed and then the start circuit is closed and opened again.
– the start circuit is closed and then opened again once the input circuit is closed.
The LED "K3" lights when the start circuit is closed and goes out when the start circuit
is opened.
} Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.
