The ramp operating system for the Precor EFX 546i ellipticals has a battery monitoring system. Units are equipped with a 12V battery. If the battery voltage falls below 11 VDC when ramp movement is initiated or the battery voltage falls below 10 VDC after ramp movement has been initiated, ramp movement will be stopped and the message “NO RAMP LOW VOLTAGE” will be displayed. Ramp motion will not be enabled until the battery voltage exceeds the above limits.
The battery voltage must be raised to correct this condition either by battery charging or battery replacement. This is strictly a battery problem and not a lift system or lift motor problem.
