Wiring :
The relay contact output on the rear panel informs of the occurrence of a system error.
Another relay contact output informs of the time until end of the internal memory space
(selectable from 1, 2, 5, 10, 20, 50 or 100 hours) before the data is overwritten, or of the
time when the remaining space on the external storage medium reaches to 10% of
whole capacity.
