LED INDICATOR RANGE Indicator light H2 - low engine oil pressure If the engine oil pressure drops during operation below a preset value, which depends on the momentary Diesel engine RPM, the indicator light H2 lights up after 2 seconds. At the same time, the buzzer will sound to alert the operator that the oil pressure is too low. Return the engine immediately to low idle Charge indicator light H12 Indicator light H12 lights up if the starter key is moved to contact position and turns off as soon as the engine starts. During operation, this indicator light lights up if the alternator V-belt or the electrical charge system is defective. Turn the engine off and correct the problem.
Engine coolant temperature gauge P2 During operation, the indication must remain in the green range. If the engine coolant overheats (coolant is above 100°C = 212°F), the red LED indicator light 63 starts to light up on the right end of the indicator. Simultaneously, the buzzer will sound in the cab and the warning signal E503 will appear on the LCD screen The engine power is reduced and the working pumps return automatically to minimum flow at the same time. Stop working soon and keep the engine running at high idle. If the default persists for over 60 seconds, lower the engine RPM to low idle and turn the engine off after 3 -5 minutes. Locate the reason for the trouble and get it repaired.
Fuel gauge P3 The LED indicator lights show the fuel level. When the both red LED 62 light up, about 10% to 20% fuel are left in the tank as reserves.
