Hi, i need help.i have digital temp controller typre sdc21 from yamatake, it controls the temp of fuel system using pid, there is an EV1 , EV2 and EV3 setting,i wonder if this is the alarm setting ? How can i set up the high and low temp alarm, i tried to play these EV but no success. Thanks in...

Hi, i need some advice, we have generator rated 300 kw , 440 v 60 hz, brushless type. when we start eh generator it only gives 50 volts from the main terminal instead of 440 v, avr have changed already, rotating rectifier changed also, all meggered ok. but same result. freq is ok. any other...

thanks. I will try ur advice.

just a new set..less than a year.

our genies uses mechanical governor. i'm just wondering why the load sharing diff is changing..if there is some problem with the load sharing due to governor or some adjustment, it would show uniform reading and not that, now good then later not good. sometimes the diff is only 2 kw, after some...

hello guys! i need some technical advice about our generators problems. we got 3 gen rated 230 kw each using mechanical governor, brushless self excitation. if 2 gen are in parallel, the sharing of kw not continously stable. sometimes ok then after several mins the diff is too big, say 45 kw. we...

Hi guys, i need some technical advise about the refrigeration system. Is it possible to convert the cold storage from positive temp application say 5 - 10 deg C ( usually for vegetables & dairy products)to minus temp application , say -12 to -18 deg c. without chinaging the size of the...

is there any rules regarding the support bracket for the pipes around dry area like engine room ( angle bar ) to be made galvanize?? please need your help guys. I'm trying to check some rules but could not find any. thanks in advance.

thanks for your help. i will check it out.

Hi guys, Is there any particular items to be inspected for the ship's installation cables, i.e. solas rules or any other class rules. thanks in advance.

thanks a lot for all advise. we will try to carry out this helpful tips.

Pls any anybody who could give me some causes/reasons of generator losing its excitation. every time we start generator, there is no 440 volts coming in and we need to flush with 12 v battery to attain 440 volts, once the gen is loaded , say 30 kw or more, the gen load starts seesawing while in...

thanks for your reply. I think also that this is the correct way. I wonder what really we are testing specifically during the load test of generator.

thanks. my query is not about the water resistance bank. I would like to know which is the proper way of doing load test for small gen, (250kw), is it individual load test or just connect 3 gen in parallel and do the load test. is there any difference of this.

thank you for your valuable info. I got 3 gen set, is it a good practice to load test individually or just connected these 3 in parallel operation to make short cut dont know which one is the proper way? is there any difference if you take the parameters of each gen while running individualy and...
