Page 3: Introduction
Introduction Lectrotab introduces an automatic leveling control system to maintain the boat on a level plane and ensure a comfortable ride. If sea conditions change, adjustments in boat speed occur, or passengers move about the boat, the automatic leveling control system utilizes built in sensors to correct the attitude of the boat to maintain the proper level. -
Page 4: How Do Trim Tabs Work
How Do Trim Tabs Work Boaters will enjoy many performance and efficiency benefits by adding Lectrotab trim tabs. Lectrotab trim tabs improve fuel efficiency, increase boat speed, accelerate shallow water planing, eliminate porpoising, and enhance the overall boating experience with a more comfortable ride. -
Page 5: Operational Overview
Control configured for 20 foot or larger boats: The auto leveling control system may be configured for boats larger than 20 feet to effectively maintain the correct boat level. For vessels over 50’ please contact Lectrotab for correct matching of ALC control to actuators and tabs. -
Page 6: Control Box Installation
Control Box Installation ALC-1D, ALC-2D For ALC-1D (dual station displays) or ALC-2D (dual station, dual actuator/tab) Mounting Black Control Box: Find a high and dry location to mount the black control box and as close to the trim tab actuators as possible. -
Page 7: Wiring Connections
Wiring Connections Connecting the Actuators to Black Control Box: Carefully follow the actuator and tab installation guidelines in the Lectrotab Operation and Installation Manual included in all of our kits. Once the trim tab plates and actuators have been installed, route the actuator cable to the black control box and attach the cable to a secure fixture every few inches to prevent the cable from getting caught on gear and becoming disconnected. -

Wiring ACL-1D or ALC-2D For ALC-1D (single actuator, dual station display) or ALC-2D (dual actuator, single or dual stations) Note: For ALC-2D dual actuators per tab, connect second actuator in parallel with one shown in diagram to match wire color. -
Page 9: Control Box Calibration
Display/Control Box Calibration ALC-1D or -2D (Single actuator, dual station or dual actuator) Calibrating the Display/Control Box: For the automatic leveling system to function properly, the trim tab type, position and electrical current draw must be known. This information is automatically acquired and stored in memory during calibration. -
Page 10: Automatic Control Setting
ALC-1D or -2D Display Settings and Operation Automatic Control Setting and Operation: After the installation, calibration and verification have been completed, take the boat for a test drive and store the correct level or attitude as described below. Operate the boat at a typical cruising speed (not maximum speed). Manually adjust the trim tabs until the desired boat level or attitude is attained. -
