The ramp system has a battery monitoring system. If the battery voltage falls below 11 Vdc when the ramp movement is initiated or the battery voltage falls below 10 Vdc after ramp movement has been initiated, ramp movement will be stopped and gives that error message. The ramp will not be enabled until such time as the battery voltage exceeds the above limits. The battery voltage must be raised to be to correct this problem either by charging or replacing the battery.
