Switch Operation

The operation of all Lenco switches is based on the position of the bow. To lower the starboard bow, press the right (starboard) side of the switch where it reads Down. This lowers the port tab. To lower the port bow, press the left (port) side of the switch where it reads Down. This lowers the starboard tab.

Indicator Switch (123SC) with Self Check Feature

On the Indicator switch, the L.E.D. lights on the sides of the display show how far that tab has moved. When the on/off switch is turned on at the helm or the engine’s tachometer circuit becomes active, the L.E.D. displays on the indicator switch light from top to bottom and immediately extinguish from bottom to top to indicate self test at power up. If there is a problem with an actuator connection the L.E.D. displays shows every other light red ”ON“ at the side that has the problem (see Fig.1). After self test is complete (1 to 2 seconds) the L.E.D. displays show one up arrow on each side of the switch. This shows that both tabs are fully retracted. While operating the tabs, the L.E.D. displays indicate the position of the tabs by lighting up the further they are pressed down. As the switch is pressed up, the lights go out. When power is removed from the switch, the tabs retract from any position before powering down (See page 8 for more information).

Dual Ram Indicator Switch (123DR)

At start up the L.E.D. displays show one up arrow on each side of the switch. This shows that both tabs are functioning and are fully retracted. While operating the tabs, the L.E.D. displays indicate the position of the tabs by lighting up the further they are pressed down. As the switch is pressed up, the lights go out. When power is removed from the switch, the tabs retract from any position before powering down (See page 8 for more information).

RetroFit Kit for Bennett Trim Tabs Installation Instructions

Lenco Marine’s RetroFit Kit is designed as a direct replacement for the Bennett hydraulic power unit (HPU) on systems using Bennett's 4-ring standard trim tab actuators.

Note: Bennett Joystick Control can not be retrofitted to the Lenco Actuators.

These instructions should be followed completely. See page 5 for complete Tools and Materials List. If you experience any problems not covered, please call the Lenco marine Customer Service line at 772-288-2662.

Make sure the power is removed from the Bennett Trim Tab System before installation.

Pre-Installation Instructions

1) _Disconnect the Bennett hydraulic pump unit (HPU) from the Bennett wiring harness and drain as much of the hydraulic fluid as possible into a container for proper disposal later. Remember that automatic transmission fluid (ATF) is to be disposed of only at an approved collection site in your area; do not discard in the regular trash. Discard hydraulic pump unit (HPU). Leave Bennett wiring harness in place.

2) _Remove and discard the Bennett trim tab cylinders from the boat transom and remove the hydraulic line at the connection. It helps to have several rags handy to soak up the oil. Remove and discard old hydraulic lines.

3) _Disconnect the Bennett cylinder from the trim tab plane by tapping out the small black pin at the base of the cylinder where it attaches to the plane. You will first have to remove one screw from the lower mounting bracket as this holds the pin in place. Do not remove the lower mounting bracket, as you will need it later.

 

Installation Instructions

1) _Insert the actuator cable through the appropriate hole in the upper mounting bracket (supplied with the kit) until it reaches the actuator. Insert the actuator cable through the gland seal until it reaches the upper mounting bracket.

Note: For appropriate orientation of upper mounting bracket and gland seal, (see Fig 1).

You will need to clean the mounting surfaces on the transom with a cleaning solvent such as mineral spirits or alcohol to remove all oils and dirt before final mounting.

Insert the actuator cable through the transom. With the actuator loosely supported, bed the upper mounting bracket and screws with 3M 5200 adhesive caulking. Start the provided #14 x 1-1/4" (3.17 cm) stainless steel sheet metal screws through the upper mounting bracket and into the transom. MAKE SURE TO LEAVE THE SCREWS ONLY PARTIALLY INSTALLED.

Insert the actuator clevis (mounting ear) into the upper mounting bracket and hold in the approximate installed location. Pass the actuator cable through the transom removing slack on the cable until it looks like the installation on Fig 2.1 on page 6. Remove the actuator from the upper mounting bracket and finish installing the previously started #14 x 1-1/4" (3.17 cm) stainless steel sheet metal screws through the upper mounting bracket and into the transom.

(Continued on page 15)

End of page 14


 

We recommend using 3M 5200 adhesive caulking to bed the upper mounting bracket and screws.

DO NOT OVERTIGHTEN.

Attach the actuator to the upper mounting bracket using the 1-1/2" Delrin Pin provided.

2) _You are now ready to attach the Lenco Actuator to the blade.  First insert the 1-1/4" Delrin Pin part way through the hole in the Bennett lower mounting bracket and insert through one of the four black washers provided in the kit. Place the actuator into the bracket and tap the pin through. Continue through the second washer and other side of the bracket. Replace the bracket screw removed in step 3 on page 14. This will lock the pin in place and prevent it from falling out.

3) _Now you will need to hook up the Lenco Actuator wires inside the bilge/rigging area. First cut the wire connector from the Bennett wire harness where the pump used to be. Strip the four harness wires and connect to the four Lenco wires using the heat shrink butt splices provided in the kit. Make sure to use the proper crimping tool and then heat all connections for a tight waterproof seal. Tie-wrap or secure in some fashion to a dry location to help prevent the connectors from getting too wet.

4) _Switch Installation: Remove Bennett switch and install new Lenco Switch. Follow the switch wiring diagram on page 16. See page 7-8 for complete switch kit installation instructions.

Please follow the instructions and drawings carefully.

Lenco Hatch Lift Installation/Operation

Due to the many different variables involved with the numerous applications for Lenco hatch lifts, installation is never the same. Here are some general guidelines that can be of assistance:

• _The actuator is most powerful when it is installed vertically at 90 degrees.

• _Lifting capabilities decrease (due to the fact that the force pounds increase) the closer the upper or lower mount is located to the hinge.

• _The further from a vertical position the less lifting capability. When retracted, Do Not position hatch lift at an angle less than 45 degrees.

• _Dual hatch lift systems are recommended for hatches over 500 pounds (226.79 kg) of force.

• _Lenco hatch lifts are designed around a ball screw that spins freely when hatch is fully open or closed.

• _The hatch lift must be allowed to free spin at both ends of its stroke or it will continue to push or pull against any resistance potentially damaging the hatch lift or the hatch itself.

• _Failure to make accurate measurements could cause damage to hatch lift or the hatch itself.

• _Lenco hatch lifts are waterproof and will not drift.

• _Lenco hatch lifts are offered in both 12 and 24 volts.

OPERATION

The function of the Lenco Hatch Lift System is simple. Since the hatch lift is based around a ball screw it is able to push a heavy load and remain at a constant position. To raise a load, extend the hatch lift by pressing on the upper part of the switch. To lower a load, retract the hatch lift by pressing the lower part of the switch.

In case of power failure, Lenco hatch lifts are supplied with two clevis pins at the mounting brackets. To pull this pin out while the hatch is closed, you can: A) Rig a cable to pin and rig to a point outside of the hatch. B) Install an inspection plate where the pin will be accessible. C) Install Lenco's hatch lift slide bracket (Part # 70381-001). This will allow you to pull the hatch open 4" (10.16 cm) in order to reach and pull pin.

Lenco Hatch Lift Mounting

1. _Follow the chart above to figure out load on the hatch lift. maximum load is 500 lbs. (226.79 kg)

                  Y = Total length of hatch

                  X = _Length from the hinge to the hatch lift mounting point

                  W = Weight of the hatch to be lifted

2. _Determine the angle of the hatch lift mount. Do not exceed 45 degrees from center.

3. _Mount the hatch lift on the desired location as per the above instructions. Important: It may be necessary to shim the upper or lower mounting bracket up or down so the hatch does not bind when fully closed. The hatch lift does not stop pulling until it has reached its fully closed position. If the hatch fully closes before the hatch lift is fully retracted, it will cause damage to the lift or the mounting hardware. Shim the hatch lift with stainless washers for small amounts of length. Use Lenco shim part #50015-002 for lengths greater then 1/8" (3 mm).

4. _Wire to switch according to the hatch lift wiring diagram on page 17.

Trim Tab Maintenance Tips

CLEANING

_The attractive surface appearance of stainless steel cannot be regarded as completely maintenance-free. Our 304 Series Stainless Steel may in fact stain, discolor, or accumulate a layer of surface contamination (dirt and grime) during the normal course of the life cycle. Minute particles of dust and rust may adhere to the stainless steel during shipping, installation, or storage at OEM or retail locations. Also, please remember that some types of stainless steel fasteners tend to “bleed” over the tabs and onto the boat. To achieve maximum corrosion resistance, the surface of the stainless steel must be kept clean and free of all of these contaminants.

• _Lenco recommends an acid and water solution to clean the tabs.

• _MaryKate’s On & Off Product is a good choice. Biodegradable, but please follow the manufacturer’s instructions before applying.

PAINTING YOUR LENCO SS TRIM TABS and ACTUATORS

Painting your tabs and actuators with marine antifouling paint will discourage marine algae or growth from adhering to these surfaces.

• _Please follow the instructions supplied by your choice of marine paint suppliers.

• _When applying paint to the actuators, be sure that they are in the fully retracted position. Do not paint the stainless steel ram above the area that is exposed when retracted.

• Do not paint under the anode or the anode itself.

SACRIFICIAL ANODES FOR YOUR LENCO SS TRIM TABS

Be aware that stray currents in your marina or in a visiting marina can cause damage to your trim tab blades if not protected by sacrificial anodes.

• _The addition of anodes on each tab will deter electrolysis.

• Do not paint under the anode or the anode itself.

• Check Anode condition frequently. Replace when necessary.

ELECTROLYSIS IS NOT A MANUFACTURING DEFECT AND IS NOT WARRANTABLE.

VISUAL INSPECTION OF SYSTEM

• _Periodically inspect all wires, mounting brackets, and hardware for damage.

• _Make sure all mounting brackets and hardware are secure and working properly.

• _Periodically test system for smooth operation.
