Input .
The digital input can be controlled by the process control system.
The reaction occurs when a short circuit of the input takes place;
the signal must be bounce-free.
IMPORTANT
If Safety Mode is enabled, the digital input is disabled automati-
cally.
The digital input is only available as an option. It is available for ver-
sions with HART signal, but not for detectors with fail-safe signal
output.
