Cause : Control stage over temperature- This trip indicates that a control stage over-temperature has been detected if Cooling Fan control (06.045) = 0.

  • Increase ventilation by setting Cooling Fan control (06.045) > 0.
  • This trip causes the option module to go to standby and Potential Drive Damage Conditions (10.106) bit 1 to be set.
