SEQUENCE OF OPERATION( AUTOMATIC PROCEDURE )

BUILDING LOAD

NORMAL OPERATION

1. ATS are in normal position connected to utility source

2. All generator set paralleling circuit breaker open

BUILDING LOAD

LOSS OF NORMAL POWER

1. Upon reciept of start signal from any ATS all generators automatically and independently start.ATS

2. Any genset at normal operating condition will closed each GCB at deadbus condition

3. Succeeding genset will synchronize to the emergency bus

BUILDING LOAD

ATS TRANSFER TO EMERGENCY POWER

1. After the preset time delay expire ATS will transfer to emergency power.

ATS

LOAD MANAGEMENT ( LOAD DEMAND CONTROL )

BUILDING LOAD

TOTAL LOAD IS 80%

1. All synchronized generators will share the load equally

ATS

BUILDING LOAD

1. If the total load is reduced to 20% of the total capacity while the 2 generators are running

ATS

2. The system will shut off the GCB # 2

3. Priority Genset # 1 will received the reduced load

BUILDING LOAD

1. Single generator is running and reached 70% of its rated capacity

ATS

2. The system will start genset # 2 synchronized to online generator and share load equally

NORMAL POWER RETURNS

BUILDING LOAD

1. When normal power return, ATS will transfer power from emergency into normal power after a preset time delay

ATS

NORMAL POWER RETURNS

START SIGNAL

2. System start from ATS will be remove and the genset will turn off after cool down timer expires

MANUAL PARALLELING USING DEIF AGC - 4


1. Before any attempt to start and parallel the generators, check that all generator paralleling circuit breaker are all in OFF position. Generator controller auto mode must be switch on. 2. Press MODE push button (SELECT SEMI-AUTO MODE) located on the front face of DEIF controller (G1 and G2) and then press START button the generator will start and ramp to rated voltage and frequency.


Mode Button

Start Button

3. Check if run and generator voltage LED illuminates , it means the generator is protected and ready.4. Select the generator (G1 and G2) to be online first, then press CB CLOSE/OPEN button on the DEIF controller. The controller will automatically detects if it is a paralleling mode or a single mode


CB Close/Open Button

Run LED

5. To synchronize the second generator, press CB CLOSE/OPEN button on DEIF controller , the digital synchroscope will automatically display during synchronization time and then it will disappear after generator breaker closed. Available loads on the bus will automatically load share to the units online. Typically the load share percentage factor is 50 %.


CB Close/Open Button


6. To stop the G1 and G2 press STOP button on DEIF controller to perform engine cooling down. When the preset cool down timer elapse the engine will automatically shutdown.

Stop Button

BASIC TROUBLESHOOTING GUIDE


GCB Fail to CloseProbable Cause

• Circuit Breaker control CB tripped off• GCB Closing relay defective (3XG)• Circuit Breaker Spring Discharged

• Defective closing coil , de –energized• Controller relay output defective• GCB control transformer defective or no output

Corrective Action

• Check GCB control circuit, reset control CB• Replace defective closing relay• Manually charged circuit breaker using manual handle• Replace defective closing coil• Replace or check defective under voltage trip coil• Check controller input / output status


GCB Fail to OpenProbable Cause

• GCB opening relay defective (3YG)• Controller relay output defecting• Control supply loose• Defective tripping coil

Corrective Action

• Manually open circuit breaker using manual button on circuit breaker• Check CB opening control circuit (Refer to Wiring Diagram)• Check controller input / output status


Fail to Synchronize

Probable Cause

• Analog output from controller has too low output range • Toho Electronic governor controller cannot regulate the voltage and frequency of incoming generator • Speed Bias control not responding• Voltage Bias control not responding

Corrective Action

• Check controller analog output maximum settings• Check and Calibrate speed bias control• Check and calibrate voltage bias control


`

Generator fail to startProbable Cause

• Fault and Alarm is active• Defective generator run relay (4x)• MGS controller not in auto• Low Battery voltage

Corrective Action

• Check and reset fault and alarm active• Replace defective run relay• Switch MGS controller to auto mode• Check and replace battery• Check automatic battery charger if operational or defective


Probable Cause

• Analog output from controller has too low output range• Generator fuel lines and filter is clogged • Generator governor control unable to accept speed bias signal• Defective controller speed governor output • Faulty control cable connection

Corrective Action

• Check and calibrate speed bias control• Replace clogged fuel filter• Check and calibrate generator governor control system• Check control cable connection

Generator not able to take load at 100 %


Probable Cause

• Loose governor control sensing• Loose control cable connection from Toho Electronic governor control • Generator fuel filter clogged

Corrective Action

• Check all control cable connection for possible loose ( Refer to Wiring Diagram )• Replace clogged fuel filter• Check and calibrate governor control systems

Generator speed unstable or hunting
