7) Fault Stimulation

 

 

Remain in the Automatic mode. Using a short wire with both ends strip of insulation, connect one 
end to negative terminal T01. Touch the other end to Low Fuel Level alarm input T16. If the 

LFL 

parameter is set to ‘0’, then the display remain at 

Aut

 but alarm bell sounds and Low Fuel Level 

fault lamp flashes. If the  

LFL

  parameter is set to ‘1’, then the display flashes  

LFL

,   alarm bell 

sounds and Low Fuel Level fault lamp flashes. Press and release the 

MFB

 button once to accept 

the alarm. Bell is silenced and Low Fuel Level fault lamp remain lighted.
Next, touch the Over Speed alarm input T15. Notice how the display shows 

LFL

 but flashes the 

OSP

, the same with the fault lamps. Alarm bell sounds again. The DAMF-5 can differentiate a new 

fault once the old fault was accepted. Press and release the 

MFB

 button once to accept the alarm.

Now, touch the High Water Temperature alarm input T14 follow by External Fault Alarm alarm 
input T12. Notice again how the display shows 

LFL

 follow by 

OSP

 but flashes 

HWT

 and 

EFA

the same with the fault lamps. 

HWT

 and 

EFA

 are treated as new faults. 

Note; 

EFA

 does not have fault indicating lamp. Its fault lamp or lamps is located at the external 

alarm   annunciator   unit   which   is   added   when   the   local   fault   indication   in   the   DAMF-5   is 
insufficient. Press and release the  

MFB

  button twice to accept and reset the alarm. The display 

reverts back to 

Aut

.

To stimulate Fail To Start, you have to prepare a jumper wire from  

SFC

 input T04 to negative. 

This jumper connection can be done at the Termination Connectors side. If this test is done at site 
where the gen-set is connected and ready to start, remember to switch off the Starter Control 

MCB

Assuming that all parameter are set at default, to begin Fail To Start test, connect the jumper wire 
to negative. The display shows the 

SFt

 count down follow by the 

Crt

 count down and 

rSt

 count 

down. The 

Crt

 count down and 

rSt

 count down is repeated 6 times before  Fail To Start alarm is 

triggered. Notice the followings before the alarm is triggered, the Fuel Solenoid LED is lighted, 

FSR

 relay is energized, when 

Crt

 count down begins, the Starter LED is lighted and 

STR

 relay 

energizes, when 

rSt

 count down begins, the Starter LED is off and 

STR

 relay de-energizes. Once 

the alarm is triggered, the display flashes  

FtS

, alarm bell sounds and Fail To Start fault lamp 

flashes. Press and release the 

MFB

 button twice to accept and reset the alarm The display reverts 

back to 

Aut

.  At this stage the 

LOP

 fault cannot be tested because the gen-set did not start. LOP 

fault test is only done after Automatic Run. Do not remove the 

SFC

 input T04 jumper wire.

8) Automatic Run

 

 

Remain in the Automatic mode. To stimulate Generator Run, you have to prepare another jumper 
wire from 

GRR

 input T05 to negative. To begin, connect the 

SFC

 input T04 jumper to negative. 

The display shows the 

SFt

 count down follow by the 

Crt

 count down. During the 

Crt

 count down, 

connect the  

GRR

  input T05 to negative. The display shows the  

OPt

 count down follow by 

run 

with the moving 

_. _. _. 

 Note, the Fuel Solenoid LED is lighted. At this stage the 

LOP

 fault can be 

tested. Use the negative T01 wire and touch the 

LOP

 alarm input T13. The display shows the 

ESt 

count down, Fuel Solenoid LED off, Energize Stop LED lighted and 

LOP

 fault lamp flashes. After 

count down, the Energize Stop LED is off and the display flashes 

LOP

. Disconnect the 

SFC

 input 

T04 and 

GRR

 input T05 jumper wires from negative. Press and release the 

MFB

 button twice to 

accept and reset the alarm. During the 

 

 

ESt

    count down, the alarm cannot be accept or reset.

 

 

9) Automatic Shutdown

 

 

Remain in the Automatic mode. Repeat the Automatic Run until the display shows 

run

. To begin, 

disconnect the 

SFC

 input T04 jumper from negative. The display shows the 

Sdt

 count down follow 

by the  

ESt

  count down. Notice, when  

ESt

  count down starts, Fuel Solenoid LED off, Energize
