I've not managed to find the answer on here so hopefully this is childs play to someone.

Just wired in 2nd hand machine. 202 alarm pops up from start up. Sparky finds a tripped relay. Next day turn on 202 comes up again. So I turn of check all stops are out and re boot.

Pop sound from the electrical cabinet and a 200 alarm pops up.

Could it just be phasing. Not got the coolant rigged up yet to check pump direction.

Any help would be ace.

I had similar alarm it was my coolant pump overheating. Relay was in a tricky place to reset. If your is phased backwards maybe the coolant pump is triggering it immediately but it should only do it when you turn it on? Might be something else who knows.

If your hydraulics come up to pressure your phasing is fine
 
brand new to you machine?
id say dead short to ground somewhere from a dangling set of 3 phase wires
the electrical will tell you from what thermal is popping
