The pump must not be running when the engine is stopped, nor may it be used for
pre-lubricating purposes. Neither should it be operated in parallel with the main pump, when
the main pump is in order.

The engine control system starts the pump automatically via a motor starter, if the cooling
water pressure drops below a preset level when the engine is running. There is a dedicated
sensor on the engine for this purpose.
14.4.1.5 Stand-by pump, LT cooling water (if installed) (4P05)
The engine control system starts the pump automatically via a motor starter, if the cooling
water pressure drops below a preset level when the engine is running. There is a dedicated
sensor on the engine for this purpose.
14.4.1.6 Circulating pump for preheater (4P04)
The preheater pump shall start when the engine stops (to ensure water circulation through
the hot engine) and stop when the engine starts. The engine control system handles start/stop
of the pump automatically via a motor starter.
