Operating modes
}
Dual-channel operation (contact or semiconductor outputs from ESPE) without detec-
tion of shorts across contacts
}
Dual-channel operation (contact or semiconductor outputs from ESPE) with detection of
shorts across contacts: redundant input circuit, earth faults in the input circuit or shorts
across the input circuits are detected.
}
Monitored manual start: The supply voltage must be present and the safety circuits
closed before the start contact is closed. The unit is not active until the start button has
been operated once the waiting period has expired (see technical details).
WARNING!
Muting start despite triggered safety function
When the Muting function is started even though the protected field of the
light guard, for example, is interrupted by a person, the machine/plant will
start up again and this may lead to serious injury and death.
Before you start the Muting function, the protected field has to be free and
the OSSD have to be in OFF state. The start has to be triggered manually
by the operator.
