PRODUCT MANUAL
52ST Below Deck Compact Motor™

ANDERSEN Stainless Steel Winches®
Your Andersen winch is made with the care and craftsmanship that come from more than sixty years of experience. Andersen winches are built to last, to retain their exceptional finish and to deliver season after season of reliable performance and sailing  pleasure to their owners through the years.

Compact Motor™ functionality
The Andersen Compact Motor™ is a brushless DC motor, carefully matched to a low profile planetary gearbox, which requires less space for installation and draws considerably less current than traditional motor/gearbox configurations. Simplified electrical installation requires no external control box.

The Compact Motor™ includes a dedicated circuit breaker with integral controller and an illuminated “intelligent” push button which regulates speed and power in proportion to the pressure applied.
Manual operation is possible at any time using a normal winch handle.

Monitoring and protection

The integrated controller will cause the motor to stop without tripping the circuit breaker if one of the following conditions is detected:

• Maximum pulling load exceeded. The motor will cut out if the pre-set maximum pulling load of the winch for electrical operation is exceeded. Operation can resume within a few seconds when the load returns below the limit.
• Overheating. The motor will cut out if the temperature of the motor circuit reaches 60˚C (140˚F). Operation can resume when the temperature returns to normal.
• Maximum continuous run time exceeded. The motor will cut out after running continuously for 4 minutes and 15 seconds. Operation can resume after releasing the push button to pause operation for at least 30 seconds.

In these cases, the illuminated push button will flash, indicating that the controller will reset automatically when operating conditions return to normal.

SAFETY NOTICES

Before Installation

Before installation, record the version number of your winch and the serial number of your motor in the space provided on the front cover of this manual for future reference.
These details can be found as shown below.

Installation Instructions

STEP 1
Determine the position of the winch and motor unit

1.1 Magnetic fields in the motor may affect compasses even when the motor is not in use. Install the motor at least 1m (3ft) away from any compass, and always have your compass recalibrated after installation.
1.2 The winch should be positioned with the recommended line entry angle of 3-8° from horizontal.
1.3 Refer to the Winch Data Sheet for your winch model for clearance/space requirements for the motor unit below deck.
You may choose to drill a small pilot hole to indicate the position of the centre of the drive shaft, to assist with this.
1.4 Note the location of the drain port in the base of the motor.
If the mounting surface is not horizontal due to deck camber or other factors, plan the installation such that the drain port is situated at the lowest point in relation to the slope of the mounting surface. The drain tube [A12] will be attached to this port to allow any moisture from condensation to escape and drain to the bilge.
1.5 The self-tailing arm should be positioned to allow the rope to drop clear of the winch as it feeds out of the self-tailer.
Positions will typically be as indicated by the shaded sectors in the diagram.

STEP 2
Install the deck plate

2.1 Refer to the product manual for your 52ST winch. Disassemble the winch and base cover to access the deck plate for installation.
Remove the plug in the base plate to expose the octagonal hole where the motor drive unit will be connected.
2.2 The drilling template [A3] can be used to identify the locations on deck for the mounting holes and deck cut-outs. The self-tailing arm of the winch can be adjusted after installation into one of eight different positions as indicated on the drilling template.
2.3 Use the drilling template as a guide for preparing the deck.
Ensure that the mounting surface is flat and there is adequate space and clearance on deck for the winch base and below deck for the motor. With the drilling template in the desired orientation, drill or cut the Ø70mm (2 3/4’’) hole for the motor drive shaft housing.
2.4 Drill the Ø8.5mm holes for the M8 deck plate mounting bolts (or 11/32” holes for 5/16” bolts).
2.5 Clean any wood or fibreglass splinters from the holes, and clean the deck thoroughly to ensure deck sealant can adhere properly.
2.6 Apply sealant to the deck where the deck plate will be fixed. For aluminium boats use a galvanic isolating ring/gasket.
2.7 Fit the deck plate to the deck using appropriate length M8 or 5/16” countersunk head bolts, large washers or backing plate, and locking nuts.

STEP 3
Fit the motor unit to the deck plate

Correct alignment of the motor during assembly is essential. Improper alignment can cause excessive noise and vibration and lead to premature wear of bearings and gears. For best results the following steps should be carried out by two persons.
3.1 Refer to the exploded diagram and remove the circlip [2], gearwheel [3] and key [4] to expose the clamping ring [6].
3.2 Back out the locking grub screw [5] and use the pin spanner [A7] to remove the clamping ring from the top of the drive shaft housing, taking care that the O-ring underneath remains in place.
3.3 Screw the M6 eye bolt [A5] into the threaded hole in the top of the drive shaft. Attach a strong rope or use a lifting device to raise the motor unit into position so that the drive shaft protrudes through the large octagonal hole in the deck plate.
3.4 Align the motor unit so that the protruding octagonal detail at the top of the drive shaft housing mates snugly with the octagonal recess in the deck plate, for a uniform flush fit.

3.5 Fit and securely tighten the clamping ring using the pin spanner, then insert and tighten the locking grub screw. Watertight assembly is ensured by the O-ring under the deck plate; no additional sealant is required.
3.6 After securing the clamping ring, reassemble the gearwheel and circlip on the shaft.
3.7 Refer to the diagrams below to check for correct clearance and alignment.

STEP 4
Fit drain tube
4.1 Remove the plastic plug from the drain port fitting and push the drain tube [A12] into the fitting until it stops. Lead the drain tube below deck to a low point in the boat where it can drain to the bilge, then cut off any excess length. At most there should only ever be a drop or two of water from condensation that will pass through the tube.

STEP 5
Install push buttons
The push button [A1] require 50mm clearance depth below the mounting surface. It is supplied with a short 190mm (7 1/2”) cable lead; this is connected below deck to a 1000mm (39”) long control cable [A10] and then to the short cable leads from the motor.
Extension cables are available and may be ordered separately if necessary.

5.1 Select the desired location. For safety reasons it is recommended that the push button [A1] is located in close proximity to the winch, preferably within reach.
5.2 Determine the preferred orientation of the hinged cover (on vertical surfaces it should open upwards). Then using the drilling template (or the rubber gasket [A2] as a guide, drill a Ø25mm (1”) hole.
5.3 Drill a Ø3mm (1/8”) hole in each of the mounting screw locations.
5.4 Fit gasket and push button in place. Secure the push button unit with the M4x20mm self tapping screws [A8], using a small amount of sealant at each hole.
5.5 Ensure that the breather channel on the side of the through-deck tube of the push button is clear and free of dirt or sealant.

Important Notes – Electrical Installation

Incorrect electrical installation will result in permanent damage to the motor and invalidation of the warranty.

Warning!
The positive cable (+RED) must be connected to the positive (+RED) terminal of the motor. Incorrect polarity will cause permanent damage to the motor.

Battery compatibility
Andersen Compact Motors™ produced from 2011 onward are compatible with wet cell, AGM and gel batteries. Furthermore they may be used with Lithium-ion batteries supplied by Super B™, MasterVolt® and Victron®. These batteries have been tested for compatibility and have built-in protection to prevent damage to the motor, battery and other elements of the system.

Operation
The Andersen Compact Motor™ electric winch uses a brushless DC motor. Brushless DC motors draw current from the battery when operating, and can send current back to the battery when spinning down unloaded. Avoid operating the winch using the motor at high speed with no load on the drum, as spinning down an unloaded motor from high speed can stress the motor and battery and could result in reduced service life or damage to the motor, battery or other elements of the system.

Further Considerations

• Always disconnect power when not in use, and before performing any service or maintenance work on an electric winch.

• Use only an original Andersen control cable to connect the push button to the Compact Motor™.
  Extension cables may be ordered separately.

• Use only the Andersen circuit breaker supplied with your Compact Motor™; do not use it with other devices.

• Supply power to the motor only from the battery; never from an external power supply.

• Refer to the wiring diagram and cable size recommendations in the Andersen Winch Data Sheet for the model and voltage corresponding to your Andersen Compact Motor™ Electric Winch.

• Never use solvents for cleaning control cables or wires – use only alcohol for this purpose.

Failure to observe these notices will invalidate the warranty.

STEP 6
Prepare the power cables

6.1 Choose the shortest and most direct route possible for the cables, in order to minimise voltage drop between the battery and the motor.
6.2 Measure the distance from the battery to the motor, and back again via the circuit breaker, to determine the necessary total cable length.
6.3 Consult the table in the Winch Data Sheet for the model and voltage corresponding to your Andersen Compact Motor™ Electric Winch, to determine the minimum wire size for your cables according to the total cable length required for your installation. If in doubt, consider choosing a thicker cable as this will help to minimise voltage drop.
6.4 Make up the cables with lugs to suit the terminals of your battery and the M8 terminals of the motor and circuit breaker. The circuit breaker can accept cable lug size for max. wire size 50mm².

STEP 7
Install the circuit breaker
Ensure that the circuit breaker is switched to the “OFF” position before making any wiring connections.

7.1 Choose a suitable location for the circuit breaker [A11] in an easily accessible position as close as possible to the battery.
7.2 Connect the two thermal sensor wires from the motor to the terminals marked “TER. SW” on the back of the circuit breaker.
7.3 Use a 0.75mm² wire to connect the terminal marked “MINUS” on the back of the circuit breaker to the NEGATIVE (–) terminal of the battery.
STEP 8
Connect power and push button cables

8.1 NEGATIVE (–) BLACK connection from motor to battery: Connect the NEGATIVE (–) BLACK terminal of the motor to the NEGATIVE (–) BLACK terminal of the battery using the (-) BLACK power cable prepared in Step 6. Tighten the nut on the motor terminal to a maximum torque of 12Nm (9 ft lb).

8.2 POSITIVE (+) RED connection from motor to circuit breaker: Connect the POSITIVE (+) RED terminal of the motor to the terminal marked “+ MOTOR” on the circuit breaker using the (+) RED power cable prepared in Step 6. Tighten the nut on the motor terminal to a maximum of 12Nm (9 ft lb). Ensure that the cable lug is not touching the printed circuit board, and tighten the nut on the circuit breaker terminal to a maximum torque of 5Nm (4 ft lb).

8.3 POSITIVE (+) RED connection from circuit breaker to battery: With the circuit breaker switched to the “OFF” position, connect the terminal on the circuit breaker marked “+ BATTERY” to the POSITIVE (+) RED terminal of the battery using the (+) RED power cable prepared in Step 6. Ensure that the cable lug is not touching the printed circuit board, then tighten the nut on the circuit breaker terminal to a maximum torque of 5Nm (4 ft lb).

8.4 Connect the push button control cable [A10] to the short cable leads at the push button and the motor.

STEP 9
Check installation

9.1 The PCB at the rear of the circuit breaker is fitted with 3 LED indicators, located along its edge as indicated in the photo.

Service and Maintenance

Proper care and maintenance of your Andersen products will ensure many years of reliable service. For your Compact Motor™ unit it is essential that the following service procedures are carried out at the recommended intervals.

Safety First! Always disconnect power before performing any service or maintenance work on an electric winch.

Periodic lubrication of the motor drive shaft lip seal:
Lubrication of the motor drive shaft lip seal is recommended once a year to condition the lip seal and avoid water ingress.
After removing the winch from the deck plate, remove the circlip [2] and drive gear [3] as shown to access the lip seal for lubrication.
Liberally apply a high quality bearing grease such as Klüber Isoflex® TOPAS NB52. Andersen Winch Grease may also be used for annual lubrication.
Isoflex® is a registered trademark of Klüber Lubrication München SE & Co. KG

Periodic replacement of the motor drive shaft lip seal
Replacement of the motor drive shaft lip seal is recommended every 3 to 5 years, depending on usage, in order to avoid water ingress and ensure a long and trouble-free service life. In practice every 5 years will be sufficient for most users, while the shorter interval is advisable for winches that see more constant usage or are installed in more exposed installations.
A service kit is provided with your new Compact Motor™ for the first lip seal replacement. It includes step-by-step instructions for the procedure and all necessary spare parts.

Winch inspection & service
Inspection and service of your Andersen winch is recommended at two year intervals. For information consult the separate product manual for your winch model which contains instructions, assembly diagrams and information about spare parts.
