What to do if MTU 20V4000L33F shows a yellow alarm for low coolant pressure?
If the MTU Engine shows a yellow alarm because the coolant pressure after the engine is too low, check the engine coolant circuit for pressure and flow.
What happens if the MTU 20V4000L33F Engine shuts down with a red alarm because of low oil pressure?
If the MTU Engine shuts down with a red alarm because the engine oil pressure is too low, then: * Check the oil system and oil heat exchanger. * Take an oil sample and analyze.
What to do if MTU 20V4000L33F shuts down with a red alarm due to high oil filter pressure loss?
If the MTU Engine shuts down with a red alarm because the pressure loss via the oil filter is too high, then: * Replace the oil filter. * If the fault message appears again after a short filter runtime, inspect the oil filter for deposits and change the oil if needed.
What to do if MTU Engine shows a yellow alarm for high exhaust gas temperature on one cylinder?
If the MTU Engine shows a yellow alarm because the exhaust temperature of a cylinder is too high compared to the average, check the emission values, ignition timing, and valve drive, ensuring the exhaust valves close properly.
What to do if MTU 20V4000L33F shows a yellow alarm for high exhaust gas temperature?
If the MTU Engine shows a yellow alarm because the weighted average of all individual exhaust gas temperatures is too high, check the emission values, ignition timing, and valve drive, ensuring the exhaust valves close properly.
What to do if MTU 20V4000L33F Engine stalls and shows a red alarm?
If the MTU Engine stalls and shows a red alarm, here's what to check: * If in parallel operation connected to mains: Check mains for frequency drop, check generator and coupling for damage. * If in isolated operation: Check throttle position, throttles for implausible closing (if throttles are fully open: Check if load step values are admissible), bypass position, air filter for contamination (replace if visible), exhaust back pressure, differential pressure over mixture cooler, emissions and injection timing, oil separator efficiency (clean compressor if needed), valve clearance, and gasket between mixture line and cylinder head for correct installation.
What to do if MTU 20V4000L33F shows a yellow alarm for high speed of the first secondary turbocharger?
If the MTU Engine shows a yellow alarm because the speed of the 1st secondary turbocharger is too high, check the ECU setting for this input, as the turbocharger speed sensor is currently not fitted.
What to do if MTU Engine shows a red alarm and shuts down due to low coolant pressure?
If the MTU Engine shows a red alarm and shuts down because the coolant pressure after the engine is too low, check the engine coolant circuit for pressure and flow.
What to do if MTU Engine shows a red alarm and shuts down due to high crankcase pressure?
If the MTU Engine shows a red alarm and shuts down because the crankcase pressure is too high, then: * Check the crank drive. * Check the air filter for contamination and replace if needed. * Check the setting of the blow-by restrictor valve. * Check the oil separator condition and replace if necessary.
What to do if MTU Engine shows a yellow alarm for high intake air temperature?
If the MTU Engine shows a yellow alarm because the intake air temperature is too high, check the ventilation system.
