Feeder Protection Relay
Operator's Manual - ANSI Version
HMI operation levels
The HMI menu consists of a user level and a technical level. The user level is used
for measuring and monitoring whereas the technical level is used for advanced
protection relay setting and can be configured to demand a password. The password
will be required after the default value 999 has been replaced.
User level
Menu groups of the user level
The user level contains four menu groups:
• MEASUREMENTS = monitored measured values
• RECORDED DATA =
• stored event values from the protection functions
• registered number of pickups of protection functions
• continuously updated registers of actual values from protection functions
• OPERATION = resetting of Trip lockout
• INFO = information on the relay, such as device type and relay serial number
You can monitor the data without a password.
How to monitor measured values
You can monitor all measured values via MEASUREMENTS in the HMI menu. In
addition, the measured current values on phases I
of I
can also be monitored by activating the monitoring state.

To access the measured values on phases I
I(unbal) and TH LEVEL via the HMI menu:
1. Press an arrow button to access the main menu.
2. The cursor will be at the first menu item, MEASUREMENTS. Press
the measured value on phase I
3. Use

as multiples of the rated current, I
current, In, while I(unbal) is shown as a percentage of the highest phase current
and TH LEVEL is shown as a percentage of the thermal trip level. Press
once more to see the corresponding primary current value for I
the conversion factors have been set to zero, dashes will be displayed instead.
4. Use the arrow buttons to monitor other measured values in the menu DEMAND
VALUES; see
Fig. 3.2.1.2.-1
5. Press
