A brief description of the general states can be found below:
•
Trip: The equipment has tripped. This bit is the OR of all the trips, of any of the functions, plus the
external trip input. If a certain function should not cause a trip, it must be individually prohibited.
In the case of the external trip input, it should be just left unconfigured.
•
50 Hz network frequency: activates when the frequency setting is 50Hz, and deactivated when
the frequency setting is 60Hz.
•
The Ready bit encompasses the correct functioning of the relay and has the following logic:
This bit is normally assigned to a contact that has a NC contact.
•
Measurement error: The self-diagnostic algorithms have detected a problem in the
measurement block.
•
Protection error: The self-diagnostic algorithms have detected a problem in the
measurement block.
•
Setting change: Activates when a change is made to the settings.
•
Date-time setting: Activates when the date-time is synchronized.
•
Local: the sum of the "HMI activity" and "Local communication" bits in the "Local
communication" state group
•
Default settings: the equipment has its default settings, not executing the trip.
•
Eeprom error: The self-diagnostic algorithms have detected a problem in the eeprom
memory, which contains the settings.
•
Eeprom change: activates when the settings or configuration are changed. The difference
between this and the setting change is that this indication includes configuration changes,
which are also stored in said memory.
•
Error events: The self-diagnostic algorithms have detected a corrupt even in the circular
buffer. This bit is reset by deleting the events (from the HMI or through communications)
•
HMI activity: this state is active if any keys have been pressed in the last fifteen minutes.
Pressing a key assumes that the relay is set to local mode.
•
Remote Control to Local: whether or not the remote control is activated
Some states have an associated event, which is a log of the change that occurs in the state.
Some states have one associated activation event, and other states have two associated events:
activation and reset. These events are saved in a buffer with a capacity for up to 1000 events,
and a time stamp precision of one millisecond.
Events can be viewed on the HMI and through communications. Reading the log does not delete
it; it remains stored in the equipment. To clear the events from the HMI, navigate to the events
menu and press and hold the "RESET" key until the number of events reads "1" and corresponds
to "Deleted events". Use the corresponding "delete events" command to delete the events from
communications.
