A brief description of the general states is given below:
•
Trip : The equipment has tripped.
•
External trip : A trip has been caused by the activation of the excess temperature input
(external trip).
•
50 Hz : If activated, the equipment works at 50 Hz, if deactivated it works at 60Hz.
•
Trip Block Enable : If the Trip Block functions is available in the model, it has been
enabled.
•
Measure error : The self-diagnosis algorithms have detected a problem in the
measurement block.
•
Ready : No errors
•
Setting change : Activated when the settings are changed.
•
Date-time set : Activated when the date-time are synchronized.
•
Local communication : this is the sum of the "HMI activity" and "Local communication"
bits from the "Local communication" state group
•
Remote communication :
“Remote communication" bit from the "Remote communication"
state group
•
•
Factory settings : the equipment is set to default settings and does not execute the trip.
•
Eeprom Error : The self-diagnosis algorithms have detected a problem in the Eeprom
memory, which contains the settings.
•
Eeprom change : Activated when the settings or configuration (user passwords) are
changed.
•
Events error : due to the fact that the events buffer is circular, new events overwrite the
older events once the buffer is full, and the older events are lost. To show this situation,
the "Events error" bit is activated. This bit is reset by deleting the events (from the HMI or
by using communications).
6.3. Fault Reports
Four fault reports are generated and each fault can store 24 events in non-volatile FRAM memory.
From the standby mode screen, press the “OK” key to access the first line of menus. Use the “▲”
and “▼” keys to position the cursor over the “FAULT REPORTS” screen. They are also accessible
pressing “◄” from the standby menu. The next information can be checked:
•
Date-time at which the fault started.
•
List of all events occurred in the equipment during the fault.
To delete the fault reports buffer, position the cursor over the fault report menu and press and hold
the "RESET" key, until there are no fault reports. There will be an event "Fault reports erased".
6.4. Date and Time by Real Time Clock (RTC)
The Protection devices require a clock, enabling them to have a date and time stamped for events
and registers. This clock has a capacitor that maintains the date and time even without power, up
to 72 hours (It is understood that the capacitor was previously loaded).
If an event queue occurs, and if synchronized with a date-time previous to the last stored event,
the relay will not rearrange the queue but will store the new events immediately after the stored
events.
This clock can be synchronized by any of the two following procedures:
•
From the HMI. In this case the date and time can be entered via the keyboard. The relay
will store the new event indicating that it has been synchronized.
