Table 4.1.15-13 Measured values
Description
Minimum earth-fault current after motor start
up
Thermal level
One-minute demand value
Demand value during the specified time range V62
Maximum one-minute demand value during
the specified time range
1)
Changing the thermal level via serial communication will generate an event code.
2)
During motor start up, the value will be displaced by dashes on the LCD and by "999" when
parameters are read via the SPA bus.
3)
If the demand value is reset and the specified time has not elapsed, dashes will be shown on the LCD
and "999" when the parameter is read via the SPA bus.
4)
Writing to the parameter will reset the number of motor start ups.
Event codes
Special codes have been determined to represent certain events, such as start and
tripping of protection stages and different states of output signals.
The events are stored in the event buffer of the relay. The maximum capacity of the
buffer is 100 events. Under normal conditions the buffer is empty.
The contents of the buffer can be read using the L command, five events at a time.
Using the L command erases the previously read events from the buffer, with the
exception of events E50 and E51 which have to be reset using the C command.
Should a fault occur and reading fails, for example in data communication, the
events can be re-read using the B command. If needed, the B command can also be
repeated.
Events to be included in the event reporting are marked with the multiplier 1. The
event mask is formed by the sum of the weighting factors of all those events which
are to be included in event reporting.
