Alarm: SRVO-136 DCLVAL
Issue I just had today.
Door cooling fan and transformer cooling fan not operable also. Manual will lead to replacement of E-stop unit or Servo Amplifier. Electrical print indicates 210 vac from power supply to cooling fans and then to E-stop unit. Ours had 203 vac at power supply but 0 vac at cooling fans/e-stop unit. With both cooling fans connected, drew too much current. R&R power supply and had 220 vac at all connections and alarm cleared.
