Good Morning everyone,
on board our ship We have a acs800 drive a AC motor.
In the display of SUPPLY SECTION of acs800 appear alarm 4280 (the fan on top of the transformer was mechanical stuck, I dismantle, I did some maintenance and I put back) by following some instruction I was able to clear the alarm by reducing the hours of the fan, by go inside with the password.
The problem is that in the DRIVE SECTION display the 4280 alarm is still present. I did not find any faulty fan, I only reduce the hours till 30000 but the alarm is still present. I must to put the hours totally in zero?
I want to add also that apparently the cooling system is not running, We believe that it should run at all the time, but there is not alarm about it.
I will be gratefully if I can receive help from some one.
Thanks in advance.
