If the demand value is reset and the specified time has not elapsed, dashes are shown on the
LCD and "999" when the parameter is read via the SPA bus.

Event codes

Special codes are determined to represent certain events, such as pickup and
tripping of protection elements 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, 5 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 by using the
C command. If a fault occurs and reading fails for example in data
communication, the events can be re-read by using the B command. If
needed, the B command can also be repeated.
The L and B commands are only available on channel 0.
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.
