Easiturn 3 Tripping House RCD
Posted: Sat 11 Jul , 2015 12:03 pm
Hi
Firstly as a newbie to owning a Denford machine thank you to everyone that participates in this forum. I recently purchased a Denford Easiturn 3, which was working when I picked it up as the previous owner demonstrated it to me. I plugged it in yesterday and switched the main isolator to on and the system booted up fine complete with an audible humming noise, which I assume is the main power transformer. I put the key switch to the ‘MAN’ position and then pressed the energise axis motors button which resulted in a sound like a contactor closing followed by the system shutting down. A quick investigation revealed that the main house RCCB had tripped, which is a Hager CD 282U rated at 80Awith a 30mA earth trip setting.
I have searched the forum as per the forum rules and the only post that I found that was similar featured a Easimill tripping an RCD socket, which suggested plugging the machine into a plain socket to test whether it was a genuine fault but I do not have that option as it’s the main RCCB that’s tripping. Now it is quite possible that something has rattled loose in the machine during its loading, journey, unloading and positioning, but also it is equally possible that this is a known issue due to power spikes as the contactor closes. Hence, can someone please suggest how and where to start the diagnostic process please, as I do not want to move the machine and open it up if the issue is not with the machine itself.
Thanks
Andrew
