We have a haas VF2, 2014 that is having issues during tool change. First, occasionally the lights would flicker and you could hear the TRP solenoid cut in and out. It progressed over a day to now the solenoid will click on and off like a machine gun for a few seconds while the lights dim and the machine will shut down. No error codes. It is also completely random, you could go 20+ times with no issue, or happen every time. I am thinking the solenoid is shorting some how but it is weird that it is not tripping a breaker and instead taking the whole machine down similar to a low voltage.
