Recorded data of the last events

REM 610 records up to five events. This enables the user to analyse the last five fault
conditions in the motor drive controller. Each event includes the measured currents,
pickup durations and time stamp, for instance. Additionally, information on the
number of pickups is provided.
Recorded data is non-volatile by default, provided that the battery has been inserted
and is charged. A master reset, i.e. clearing of targets and memorized values and
unlatching of output contacts, will erase the contents of the stored events and the
number of pickups.
REM 610 collects data during fault conditions and motor start ups. When all pickup
or alarm signals have been reset, an element trips or the motor start up has ended,
the collected data and time stamp will be stored as "EVENT1" and the previously
stored events will move one step forward. When a sixth event is stored, the oldest
event will be cleared.
