Alarm contact
The alarm contact is closed during normal operation (N/C).
It opens in the case of alarm or power outage. As a result,
a failure message is provided even in the case of line
breakage (fail-safe behavior). For contact ratings, see
Specifications.
Error messages can also be signaled by a 22 mA output
current.
The operating behavior of the alarm contact is shown on
Pg 91.
The alarm delay acts on the LED, the 22 mA signal, and
the alarm contact.
