Set delay time:
On units with selectable delay time, the delay time of the safety contacts 47-48 and 57-58
can be set on the front of the unit using a screwdriver.
Reset function:
The delay time cycle can be ended prematurely by opening the reset circuit Y39-Y40. For
this purpose, one N/C contact is connected between Y39-Y40 instead of a link.
Operating modes
} Single-channel operation: No redundancy in the input circuit, earth faults in the start
and input circuit are detected.
} Dual-channel operation with detection of shorts across contacts: Redundant input cir-
cuit, detects PNOZ XV3P
– earth faults in the start and input circuit,
– short circuits in the input circuit,
– Shorts across contacts in the input circuit.
} Dual-channel operation without detection of shorts across contacts: Redundant input
circuit, detects PNOZ XV3P
– 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.
} Monitored start: Unit is active once the input circuit is closed and once the start circuit is
closed after the waiting period has elapsed (see Technical details [ 352]).
} Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.
