LCI Auto Level System Overview
The LCI auto-leveling system automatically levels RVs. It uses hydraulic jacks controlled via a touchpad. Manual operation is also possible for precise adjustments or troubleshooting. The system requires sufficient voltage (12.7V DC or higher) for optimal automatic function.
System Components and Features
The LCI system typically includes a control panel (touchpad), a hydraulic power unit, and multiple motorized leveling jacks. These jacks, often made of aluminum for lightweight strength, extend and retract to level the RV. The system utilizes sensors to detect the RV’s level and automatically adjust the jacks accordingly. A fluid reservoir containing Type A ATF (Automatic Transmission Fluid) powers the hydraulic system. Some models incorporate additional features like air suspension integration and manual override capabilities for greater control and flexibility in various leveling scenarios.
Operation Modes⁚ Automatic vs. Manual
The LCI system offers both automatic and manual operation modes. In automatic mode, the system uses its sensors to determine the necessary adjustments and automatically levels the RV. This is convenient for quick leveling on relatively level surfaces. Manual mode provides precise control over each jack individually. This is useful for fine-tuning on uneven terrain, adding leveling blocks, or troubleshooting. Switching between modes usually involves selecting the appropriate setting on the control panel. Sufficient voltage (12.7V DC or higher) is typically required for automatic mode; manual mode may function at lower voltages.
Touchpad Controls and Indicators
The LCI system typically uses a touchpad interface for control. This touchpad features buttons or icons for automatic leveling, manual jack control (often individual controls for front, rear, left, and right jacks), and jack retraction. LED indicators display the system’s status, showing whether it’s in automatic or manual mode, if it’s currently leveling, or if errors have occurred. A low-voltage indicator warns of insufficient power, which may limit functionality to manual operation only. The display might also show error codes requiring troubleshooting. Consult your specific model’s manual for precise details on the touchpad’s layout and functions.
Setting Up the LCI Auto Level System
Initial setup involves pre-leveling checks, ensuring a reasonably level surface and engaged parking brake. Calibration to establish a “Level Zero” point is crucial for accurate automatic leveling. Troubleshooting any initial setup problems may involve checking fluid levels or power supply.
Pre-Leveling Checks and Preparations
Before initiating the LCI auto-leveling system, several crucial checks and preparations are necessary to ensure safe and effective operation. Begin by selecting a reasonably level parking spot, free from significant slopes or uneven terrain. Engage the coach’s parking brake firmly to prevent unintended movement during the leveling process. Clear the area around the landing gear of any debris, rocks, or obstructions that could interfere with jack deployment or stability. Verify that the coach’s transmission is in the park or neutral position. Finally, confirm sufficient voltage (12.7V DC or higher) is available; low voltage may limit functionality to manual mode only.
Level Zero Point Calibration
Before utilizing the automatic leveling features of the LCI system, establishing the Level Zero point is essential. This calibration process ensures accurate leveling measurements and prevents potential errors. Consult your specific LCI model’s manual for detailed instructions, as procedures may vary slightly depending on the system’s configuration. Generally, this involves retracting all jacks completely, then using the touchpad controls to set a reference point. This establishes the fully retracted position as the system’s baseline for future leveling calculations. Accurate Level Zero calibration is crucial for the reliable and consistent performance of the automatic leveling functions. Failure to perform this step correctly may lead to inaccurate leveling or system errors.
Troubleshooting Initial Setup Issues
If the LCI auto-leveling system fails to initialize correctly, several troubleshooting steps can be taken. First, verify sufficient 12.7V DC power supply. Low voltage will prevent automatic leveling. Check for any error codes displayed on the touchpad; consult the manual for code definitions and solutions. Ensure all jacks are clear of obstructions and that the RV’s parking brake is engaged.
