Function description
Characteristic for dual-pole outputs: Output capacitance C dependent on load current
4.4.3
Notes
}
For applications in accordance with Category 4, PL e and SIL 3, detection of shorts
between contacts must be guaranteed either via the on/off test or through other meas-
ures (e.g. asynchronous switching). A short between contacts must be simulated during
commissioning.
4.5
Fast shutdown
The module switches the outputs off immediately when:
}
The signal from the protected field evaluation (OSSD) switches from 1 to 0 (protected
field violated).
}
The signal for dynamic muting (MUTE) switches from 1 to 0. (Object interrupts advance
measuring field.)
}
The signal switches from 1 to 0 at one of the input pairs I00 and I01, I02 and I03. The
edge used to trigger the fast shutdown can be configured (see

WARNING!
When wiring an output with capacitance it is essential to note the pulse dur-
ation, repetition period and scan time of the power-up test, otherwise the
load may switch on unintentionally.
