Introduction This user’s manual describes the installation and usage of the ACS RP attitude control system from Mente Marine. It is available in print and in Pdf format at www.mente-marine.com. Symbols and abbreviations ACS LED 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. Should the automatics engage during transport, the trim tabs may be damaged.
Theory of operation The deep-V hulls of modern pleasure boats are designed to provide you with a smooth ride in rough water. The deeper the V, the more need for trim tabs to keep the boat levelled. A Roll or sideward’s inclination is dependent on the wind and passenger location. The longitudinal inclination, also called the trim angle, depends on the speed and loading. When the course is changed, winds change direction and you need to trim the boat. When passengers move, trim again.
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. This allows a quick reaction when needed and avoids unnecessary operations that could amplify a roll in high waves.
Installation ACS R and ACS RP have built-in sensors that measure the boat’s movements and should therefore be mounted upright or laying down. All angles between upright and laying down are allowed. 1) Upright 2) 3) Between upright and laying down 4) Laying down Regardless of the mounting angle, the starboard button should face the starboard side of the boat and the port button the port side. 5) Starboard button facing the starboard side 6) Port button facing the port side Drill the holes 80.0 mm (3.
Connection IMPORTANT! In retrofit installations, disconnect the wires from the old control panel before connecting the ACS. It should not be connected in parallel with the old panel. Switch off the main circuit breaker before starting the connection! Installation descriptions and a video are available at www.mente-marine.com Hydraulic trim tabs Hydraulic trim tabs, such as Bennett, Instatrim, QL and Trimmaster use a hydraulic pump unit to extend and retract the actuators.
Electromechanical trim tabs Connect the starboard actuator to terminals 5 and 6 and the port actuator to terminals 3 and 4, according to the figure that follows. Verify the connection later on and change it if necessary. *Lenco’s electronic control panels usually have a separate control box. ACS is connected after the control box directly to the wires of the cylinders. The old control panel and control box are removed.
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 and make sure the ACS is mounted properly. The AUTO indicator blinks to indicate that calibration is needed. Press the uppermost and lowermost buttons simultaneously for 5 s to start the calibration.
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 downwards. The lowermost button controls both tabs upwards.
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 up. Now, the attitude is stored in the memory, and the ACS is set in the automatic mode. Fine adjustment In the automatic mode, press any of the four buttons to alter the setting 0.5 degrees in a certain direction. Press more times for a greater change.
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 II. Step I provides a little slower correction, while step III is the fastest. The setting is optimized, if a list condition is corrected without the boat leaning over to the other side and the trim tabs are not operated too often. Press the left and right button simultaneously for 4 seconds until an indicator in the middle starts to blink.
Troubleshooting If a fault is found, an indicator will start to blink intensively. Indicators Trim tabs not found in calibration L1 Short-circuit to the positive side L2 Short-circuit to ground L3 Trim tabs not found at start up L5 R1 Wrong installation angle Supply voltage During a fraction of a second, when starting a trim tab motor, the current is much higher than normal and the supply wires, fuseholder and battery should be in a good condition.
