need arises.

 2SHUDWRURYHUYLHZ
If a disturbance occursthe operator hasa possibilityto document it so that the fault that
caused the disturbancecan be analyzed, evaluated and documented for future reference.
The operator can identify the disturbance and, for example, document the fault currents
and voltages at the time of the fault. The operator also has a possibility to retrieve data
about the protected object, which will give further information when analyzing a fault.
This implies viewing the mean current, voltage, power and frequency or primary and
secondary measured phasors. The operator can check the terminal status at any time.
In some cases the operator needs to change the way the terminal operates. This could
be changing the active setting group or a setting parameter value. This must be done in
strict accordance with the company regulations due to that a non-authorized change can
cause severe damage to the protected object if a fault is not properly disconnected.

The human machine interface is used to monitor and in certain aspects affect the way
the product operates. The configuration designer can add functions for alerting in case
of important events that needs special attention from you as an operator.

The human-machine interface consists of:
• the human-machine interface (LCD-HMI) module.

• events may occur that activates for instance a LED, in purpose to draw your atten-
tion to something that has occured and needs some sort of action.
• you as the operator may of own interest view a certain data.
Use PHQXV to navigate through menu FRPPDQGV and to locate the data of interest.

The number of buttons used on the HMI module is reduced to a minimum to allow a
communicationassimpleas possibleforthe user.Thebuttons normallyhave morethan
one function, depending on actual dialogue.
Pressing any button in idle mode will activate the HMI display.
The C button has three main functions:
•&DQFHO any operation in a dialogue window.

2. LCD unit, example of main menu
3. &DQFHO and (QWHU buttons
