MAINTENANCE
The device has been constructed principally with solid state technology, so it needs a simple maintenance. The operations of maintenance are simplified
as follows: keep the relay dry and clean, verify that all terminal blocks are well connected, periodically check the display test by which all LEDs will be on,
periodically control the right function of the output relays.
