figure 5-21 Configuration of external alarm clamps
All external alarms are defaulted to high (5 VDC) without connection. This setting
may be changed on the external alarm page to active high or active low. The severity
levels of the external alarms may be set via the web page. More information about
the external alarm settings is available in the web page and online-help.
Make sure that external alarms which are not required are set to active low or disable
them; otherwise the status will always show an alarm.
The names for each external alarm are user-definable on the external alarm page;
renaming them to indicate the use of these alarms is recommendable.
There are two external cable glands (PG7) at
the bottom of the Node. They may be used to
connect the external devices. Please note that
connecting the external devices by a wrong
type of cable may result in a loss of the water-
proofness. The recommended cable diameter is
4 - 6 mm.
