You have 2 large orange doors, Open the door on the left. You will see yellow fanuc rack. Next to the rack 2 black amplifiers they have chrome handle around them. One of them will have red alarm. Left Amp controls ram position valve, right Amp controls high low pressure valve. Only way to clear alarm is to turn control off/on. After reboot will alarm come on instantly? Only after you punch? Any loud vibration noise from the top of the ram? Goto very top of machine remove covers. Check for broken wire on both servo valves. Send me more details.
Regards,
Joe
