Figure 6-32 GuardII+ Internal Buttons

6.5.1. Alert Button
The Alert Button has three functions:

• Pressing the button will clear the monitor Alert state. This is the most common use of
the Alert button.

• Pressing and holding the button for 5 to 10 seconds will set the Alert into Alert Test
mode; the Alert Relay will perform its programmed behavior. For example, if the relay
is programmed for Momentary Normally-Open operation, holding the button for 6
seconds will force the relay closed for 4 seconds.

• Pressing and holding the button for more than 10s will set the Alert into Forced Alert
mode; the Alert Relay is set to its active state until it is reset. For example, if the relay
is programmed for Momentary Normally-Open operation, holding the button for 10
seconds will force the relay closed until reset.

6.5.2. Online/Offline Button
The Online/Offline button is used to toggle the GuardII+ state between Online and Offline.
As described in Section 4.1, the normal operational state of the monitor is Online, and
when Offline, GuardII+ is not performing measurements.
WARNING:
The monitor MUST be online for normal operation.
If GuardII+ is turned on, but has been offline for more than 24 hours, it will
automatically go online.

6.6. Single-Shot Measurements
In addition to the automatic measurements recorded by the Triggers, it may sometimes be
desirable to manually run a measurement and save it in the database. To do this:
• Use IAM to configure the GuardII+.

• Go to the Partial Discharge configuration page.
