The control panel manages three fixed-time indications and one cyclical. The indication numbers 1, 2 and 3
are of prefixed time and trigger only once, when the hour-meter reaches the programmed value. The indication
number 4 is cyclical and triggers after the programmed hours and their integer multiples. Request for maintenance
is indicated by: he flashing of the hour-meter, the intermittent lighting of the yellow warning light and the
message on the display.
Example 1: Indication 4 is programmed at 100. The indication triggers after 100, 200, 300, 400 ... hours
Example 2: Indication 1 is programmed at 100. The indication triggers at 100 hours, and does not trigger again.

PROTECTION ENGAGEMENT DUE TO ENGINE OVERTEMPERATURE
The temperature is sensed by the (TEMPERATURE) TRANSMITTER and is programmable. The protection is
adjusted according to two levels: it is engaged when they are exceeded. The alert level is programmed as a
warning; the other level is programmed to stop the engine (the overtemperature is sensed by the thermostat
which always causes the engine to stop).
