Hi, does anyone here been using this type of concrete equipment for tunnel?

I'm having a problem with the unit. This model is not the PLC version. Hydraulic system is okay but I'm having a hard time troubleshooting the unit. Input voltage in the DIN socket of drive cylinder solenoid is only 2.2v. Relays and controls are functioning well, but the controller/board only emits around 2v. There is an alarm existed and says "EC27" and based on my research it defines "low voltage". Hope you could help me fix this problem. Thankyou.
