13.3.1.3 Monitoring and Operating Relays (Controls)

The NetGuardian comes equipped with 4 relays that can be used to control external devices. Monitor the status of
your relays from the M)onitor menu > R)elays option.
Relays 3 and 4 are set to normally open (N/O) as the factory default, but each or all of them can be changed to
normally closed (N/C) by changing their respective jumper.
The four relays can be operated from this screen

13.3.1.4 Monitoring Analogs

View the current reading and the alarm status of your analog devices from the M)onitor menu > a(N)logs option.
The value shown is a snapshot of the channels measurement, not a real-time reading. Refresh the readings by re-
selecting the analogs option. Alarm status indicates that a preset threshold has been crossed and is designated by
an x.
The 6 analog measuring inputs are set to measure voltage as the factory default. If your sensors output is current,
change the appropriate analog shunt, to the current measuring position. The scaling worksheet in the provisioning
section converts all readings shown here into native units, such as degrees Celsius or percent relative humidity.
