Operation Monitoring System; Emergency Shutdown; Stopping - Man E3268 LE212 Operating Instructions Manual

When the rated speed has been reached, the plant can then be operated under load.
Acceleration of the engine from 0% to 100% is made over a time interval of 3 minutes.
This minimises the thermal load on the engine block.
The oil gauge must display lubrication oil pressure. If this is not the case, stop the engine immediately.
7.4.2

Operation monitoring system

NOTE
Engine overload
Engine damage
For this reason:
S Determine and eliminate the cause of faults and malfunctions.
The oil pressure and the coolant temperature are constantly monitored during engine operation.
If the limits are exceeded or not reached, the engine will be automatically shut off.
7.4.3

Emergency shutdown

An emergency-off button, for shutting down the system in an emergency, must be installed for each engine.
7.4.4

Stopping

The load is reduced by means of ramp control from 100% to 0% over a period of at least 3 minutes, thus
minimising the thermal load on the engine block.
WARNING
Risk of injury due to highly inflammable materials
Unburnt gases can catch fire.
For this reason:
S If there is damage to the engine shutoff device, do not shut off engine by shutting off ignition system.
S Close main gas valve.
S Turn off ignition system after engine is at a standstill.
S Ensure that the engine cannot be started by unauthorised persons.
User tip
The coolant pump will run on for approx. 5 minutes after engine has stopped.
This minimises the thermal load on the engine block.
1. Shut off gas supply.
2. The engine stops running.
3. After waiting 5 seconds, turn off ignition system
and control system.
Carefully read these Operating Instructions before starting any work!
This is especially valid for the chapter on General Safety Instructions
and the safety instructions in each of the chapters.
