Engine Coolant Temperature
The right inside bar graph, 1, registers coolant
temperature. One segment of the bar graph will be
displayed if the engine is cold. The number of
segments displayed will increase as the engine
warms up. With the engine at normal operating
temperature, up to fifteen segments will be
displayed. The normal working range is indicated by
the green area of the adjacent range display.
Should the coolant temperature exceed a predeter-
mined level, the coolant temperature bar graph will
flash. The critical alarm will sound, the word “STOP”
will flash in the central display for 30 seconds, and the
engine will automatically shut down.
Stop the engine immediately and investigate the
cause.
NOTE: The bar graph indicates engine coolant
temperature only. It is not an indication of coolant
level. The engine coolant must be checked daily.
Engine Load
The right outside bar graph, 2, relates to engine load.
The number of segments displayed will increase as
the engine load increases.
