Possible Causes

  • An AC power failure has occurred.
  • Loads are manually disconnected.
  • The load disconnection voltage has been set to a very high value on the SMU.


  1. Check whether an AC power failure has occurred. If so, rectify the fault to restore the AC power supply.
  2. Check whether loads are manually disconnected. If so, check with other maintenance personnel whether the loads can be reconnected.
  3. Check whether the load disconnection voltage (44 V DC by default) has been set to a very high value on the SMU. If so, adjust it to a normal value.
