Connecting alarm to potential-free contact

Once the alarm settings have been configured, the
alarm must be assigned to a set of potential-free
contacts. The terminals for these contacts are labelled
K201 (relay 1) and K202 (relay 2) and are located to the
right of the AC LOCAL OUT connection.

The potential-free contact can be activated in two ways:

1.

Normal: The contact closes when the alarm is
activated and opens when the alarm is deactivated.

2.

Pulse: The contact opens and closes at the selected
frequency for the configured length of time when the
alarm is activated and does so again when the alarm
is deactivated.
