Page 3: Introduction
Introduction This user’s manual describes the installation and usage of the ACS A attitude control system from Mente Marine. It is available in print and in Pdf format at www.mente-marine.com Symbols and abbreviations Attitude Control System Light Emitting Diode Security Switch off the main circuit breaker or put the ACS into manual mode before lifting or transporting the boat. -
Page 4: Theory Of Operation
Roll and pitch axes ACS A automatically adjusts the boat to ACS A automatically adjusts the boat to the optimum the optimum attitude in the roll axis, attitude in the pitch axis, improving visibility and also eliminating heeling. -
Page 5: Adaptive System
Adaptive system ACS adapts to boats over the whole range. Thanks to the adaptive functionality, the boat is set up to the optimum running attitude, taking into account differences in size and trim tab performance. It also adapts to varying sea conditions. In calm seas, a list condition is corrected faster than in rough seas. -
Page 6: Installation
Installation Control unit The control unit should be mounted in an upright position. The label on the front side is marked with an UP arrow that should point upwards and a FWD arrow that should point in the forward direction. max. -
Page 7: Hydraulic Trim Tabs
Hydraulic trim tabs Hydraulic trim tabs, such as Bennett, Instatrim, QL and Trimmaster use a hydraulic pump unit to extend and retract the actuators. The pump unit is situated in the rear of the boat and connected to the battery's negative (-) terminal. From the pump unit, a wire harness is routed to the ACS. Connect the wires to the ACS terminals 3, 4, 5, 6, according to the figure that follows. -

Electromechanical trim tabs Connect the starboard actuator to terminals 4 and 6 and the port actuator to terminals 3 and 5, according to the figure that follows. Verify the connection later on and change it if necessary. Lenco Lectrotab Ultraflex marking Black (port) White (port) -
Page 9: Calibration
Calibration For the ACS to operate properly, it needs to know the trim tab type, position, and current consumption. This information is automatically acquired and stored in memory during calibration. Before you start, ensure that no obstacles hinder the free run of the tabs. The AUTO indicator blinks to indicate that calibration is needed. -
Page 10: Verify Connection
Verify connection IMPORTANT! After calibration, verify the connection by pressing the buttons one by one and observing the trim tabs. Check the actual movement of the tabs at the transom. For the automatics to work properly, the trim tabs have to move in the correct direction when controlling them manually. The uppermost button controls both tabs down- wards. -
Page 11: Usage
Usage Attitude setting Run the boat at cruising speed. Manually control the trim tabs until you find the best attitude. Then, press and hold the auto button for 4 s, until the AUTO indicator is lit Now, the attitude is stored in the memory, and the ACS is set in the automatic mode. -
Page 12: Adjusting Gain
Adjusting gain The gain determines how fast the ACS should correct a list condition. It can be adjusted in three steps and the default setting is step I. Step II provides a correction that is a little faster, while step III is the fastest. -
