SECTION 2: SYSTEM OPERATION
A. EACH ENGINE CAN BE OPERATED AT THE SWITCH BOARD OR AT THE ENGINE.
1.
TO START AT THE SWITCH BOARD, PLACE THE ENGINE CONTROL SWITCH (ECS) IN THE START
POSITION. THE ENGINE WILL AUTOMATICALLY CRANK TO RUN.
2.
TO STA RT AT THE ENGINE, PLACE THE ENGINE CONTROL SWITCH (ECS) IN THE 'REMOTE' POSITION.
THEN OPERATE THE START SWITCH ON THE ENGINE AND IT WILL AUTOMATICALLY CRANK TO RUN.
3.
IN BOTH MODES OF OPERATION THE ENGINE WILL SHUT DOWN AND A FAILURE LIGHT ON THE
SWITCH BOARD WILL LIGHT FOR ANY OF THE FOUR FAILURES (REVERSE POWER, OVER SPEED, LOW
OIL PRESSURE, HIGH WATER TEMPERATURE.)
4.
THE ENGINE CAN BE STOPPED AT THE SWITCH BOARD BY PLACING THE ENGINE CONTROL SWITCH IN
THE OFF (RESET) POSITION, NO MATTER WHERE IT WAS STARTED FROM.
5.
WHEN THE EMERGENCY STOP PUSH BUTTON ON THE ENGINE IS USED TO STOP THE ENGINE, BE
AWARE THAT RESETTING THE BUTTON WILL CAUSE THE ENGINE TO IMMEDIATELY START CRANKING
TO RUN AGAIN UNLESS THE ENGINE CONTROL SWITCH IS RETURNED TO THE OFF POSITION.
6.
THE VOLTAGE REGULATOR 'IDLE-RUN' SWITCH MUST BE USED WHEN OPERATING THE ENGINE AT
IDLE SPEEDS FOR WARM-UP OR MAINTENANCE TESTS.
7.
VOLTAGE ADJUSTMENT CAN BE MADE BY ADJUSTING THE VOLTAGE RHEOSTAT WHILE OBSERVING
THE VOLTMETER. THE VOLTAGE LEVEL SHOULD BE THE SAME ON ALL PHASES.
8.
FREQUENCY ADJUSTMENTS CAN BE MADE BY ADJUSTING THE GOVERNOR SPEED SWITCH WHILE
OBSERVING THE FREQUENCY METER.
9.
THE GOVERNOR SPEED SWITCH CAN ALSC BE USED TO BALANCE LOADS BETWEEN ENGINES WHEN
OPERATION IN PARALLEL. THIS IS ACCOMPLISHED BY THE AMMETERS AND ADJUSTING THEIR
RESPECTIVE GOVERNOR SPEED SWITCHES ('RAISE' WILL INCREASE THE LOAD AND 'LOWER' WILL
DECREASE THE LOAD.)
10.
THE VOLTMETER SWITCH ON GENERATOR NUMBERS ONE AND TWO WILL ALSO READ ONE FHASE OF
THE LOAD BUS. THE VOLTMETER SWITCH ON GENERATOR NUMBER THREE WILL ALSO READ ONE
PHASE OF SHORE POWER.
B. EACH
GENERATOR
IS
SET
UP
TO
OPERATE
IN
PARALLEL
BY
ANY
SCHEME
OF
MANUAL
SYNCHRONIZATION. (ALL DISTRIBUTIONS LOAD BREAKERS SHOULD BE CLOSED.)
1.
START THE FIRST GENERATOR AND CLOSE ITS BREAKER TO THE BUS.
2.
ADJUST THE VOLTAGE AND FREQUENCY FOR THE DESIRED LOAD.
3.
START THE SECOND GENERATOR AND ADJUST ITS VOLTAGE AND FREQUENCY TO MATCH THE BUS
BY OBSERVING THE BUS VOLTMETER AND BUS FREQUENCY METER.
