Alarm

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.
