 count down. After 

SFt 

count down, the 

Crt

 count down and 

rSt

 count down is repeated until you touches the 

GRR

 input 

T05 to negative. If not, the Fail To Start alarm will be triggered. After the 

GRR

 input T05 touches 

negative, the display shows 

OPt

 count down and when finished, displays 

run

 to indicate gen-set is 

running. Remember to note the usual, when 

Crt

 count down begins, the Fuel Solenoid Relay and 

Starter Relay energizes, when 

rSt

 count down begins Fuel Solenoid Relay remain energized while 

Starter Relay de-energizes.

13)Test Stop

input T04 not connected) for automatic shutdown.

14)Conclusion

 

 

After finishing all the steps mentioned above, you have completed testing the DAMF-5. You can 
repeat some of the test, if you like, with different and unusual combinations not normally done in 
actual operation. For example, you can trigger different faults at different stages of count downs or 
change to different modes during count downs. We have already done a comprehensive test to 
ensure that  the software is  robust and can withstand abuse. If you have discover some  weird 
combinations of unusual test or switching over that causes the DAMF-5 software to freeze, we 
would appreciate it if you can inform us so that we can fix it. Thanks.
