Testing

Check that flow switch for shielded injection lines

works properly.

The switch can work properly only when the

fuel back leakage line is installed with consi-

stent gravity feed to the collector tank.

Alarm by the flow switch in service may be

caused by a broken line or a leaky connection.

Job

Clean switch (2) externally and make sure that con-

nections are tight.

With the engine in service, unscrew union (1) and take

out blanking cone. Put tundish on pipe connection and

fill in diesel fuel. The switch (2) should now release an

alarm as long as the diesel flow continues.

If no alarm is released, eliminate the cause of the

trouble or replace the switch.

Check that the electric lead is properly instal-

led so as not to “chafe”.
