Hi just have a question about a ycws screw chiller not starting as no fault codes show until after it tries to start 3 times and then shows motcurr/mp/hp ive checked all safeties (hp is auto reset and closed, MP module is ok along with motor thermistors), 3 phases are there and 110 volts is waiting to be switched at the arb relay board, also checked the 12vdc signal from microprocessor on terminal no. 5 to the arb relay board drops off when the run signal is activated.

please help i am running out of ideas
