Engine Local Control

System Operation

Switching control to the local ME control post:Local control has a higher priority as compared to the Remote AutomatedControl(RAC) system. This is why, to switch control to the local ME control postyou will

only have to put REMOTE ENGINE SIDE two-position switch inENGINE SIDEposition. RAC system ME control lines are then disabled. There is anindication inthe ECR and on the bridge that the ME control is executed from the localcontrolpost. Repeater engine telegraph is turned on.Switching control of RAC mode:Put REMOTE ENGINE SIDE two-position switch to REMOTE

position. Therewill be an indication at the local ME control post of where the control inRAC modewill be executed from: BRIDGE or ECR.Before switching to RAC mode, you should:

Check the position of ECR BRIDGE control post switch in the ECR;

At the active RAC post, put the engine telegraph handle (ME rpm

controller in theRAC system) in the position corresponding to the current rpm anddirection of theME crankshaft. This will prevent the so-called shock switching associatedwithan abrupt change of the ME operation.Starting the ME from the local post:

Safety solenoid valve is opened ifbackpressure more than 1 bar and closed if back pressure less then 0,8 bar orin emergency, if sludge or water will appeared in separator outlet (product

discharge line). Back pressure regulator especially significant in manualmode.In automatic mode, WATER DRAIN valve is closed, if water level in bowlisreduced. Use AUTO-MANUAL switch to switch the separator to AUTOmode.

12. Set the time of removing the sludge from the separator bowl the timeis set by

using TIME, min controller (in AUTO mode).
