Summary Alarm


Note: With alarm severity setting 'disabled' it is possible to decide which alarms do
not activate the summary alarm. For more details please refer to the Node AM/
Node AM Software manual that is part of the delivery.
The summary alarm is a DC potential-free contact relay.
Observe that the cross-sectional area of the wires to be connected must be in the range
2
from 0.4 – 0.8 mm (AWG 26-20).

There is one external cable gland at the front of the Node
AM, which may be used to connect the external devices.
The recommended cable diameter for the connection
cable is 4 - 6 mm. Please note that connecting the
external devices by a wrong type of cable may result in a
loss of the watertightness.
All external alarms are defaulted to high (3.3V TTL)
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.
