Warning indicators, faults and remedy
s
*1: In this case, oil pressure switch is “ON”.
*2: It is necessary to stop the engine, if you want to stop the working indicators and re-set the warning system.
*3: Engine speed controlled to 1800 min-1(rpm).
*4: Flashing pattern, 1 sec ON and 9 secs OFF.
High speed ESG (Electronic Safety Governor)
High speed ESG is a device to prevent over revolution of the engine. If the load to the engine becomes light for
some reason, it runs at a higher speed than the usual. In such the case, the buzzer sounds and the ESG is
activated to restrict amount of fuel injection, therefore, the engine speed varies and be controlled under 6000
min
-1
(rpm).
Low speed ESG
Low speed ESG is a device to prevent the engine from getting damage. If the engine has problems regarding
cooling water, oil pressure, and sensors, the low speed ESG is activated to restrict amount of fuel injection,
therefore, the engine speed varies and be controlled under 1800 min
-1
(rpm) or 2800 min
-1
(rpm).
