MAX POWER CT165 with Electronic Thruster Control Instruction Manual

MAX POWER CT165 with Electronic Thruster Control Instruction Manual

The use of qualified marine personnel , with experience in bow thruster installation, is strongly advised. Where possible, the boat manufacturer’s design departments, architects, and/or shipyards should be consulted, prior to installation taking place. For any boat requiring official classification, bodies of approval should also be consulted at the earliest opportunity. In any case, all other bodies, governmental or otherwise, should be contacted to ensure conformity with legal regulations relating to the boat in question.

IT IS ESSENTIAL TO READ THE FOLLOWING MANUAL CAREFULLY BEFORE INSTALLING

THE THRUSTER

The thruster is delivered without accessories (fuse, fuse holder, control panel).

1. GENERAL INSTALLATION GUIDELINES

**** In order to install the thruster in the most efficient position, follow the instructions below:

The minimum acceptable tunnel position is 188mm below the waterline

• The tunnel is ideally positioned when the distance between the waterline and the top of the installed tunnel is 250mm
• The tunnel must be installed as far forward as possible

A thruster turbine installed above its ideal position towards its minimum depth will lead to a progressive loss of performance.
Whether vertical, inclined or horizontal, it is recommended to support the electric motor.
The electric motor generates heat when in operation. The zone in which the thruster is installed must therefore be dry and ventilated.
The batteries used by the thruster must be charged by both the main engine’s alternator and an appropriate battery charger.
If the thruster is installed using a dedicated battery bank, this must be as close as possible to the thruster in order to reduce voltage loss in the electric cables.
CAUTION: In no case should flammable products be stored near to the electric components of the motor.
The drive leg must be centered in the tunnel and under no circumstances should the propellers protrude out of the tunnel.

2.TUNNEL

**** Once the final tunnel position has been determined and all dimensions have been checked, mark the center-point of the tunnel on both sides of the hull and drill holes of
8 –10mm ∅ on either side.
Using a metal rod, construct a compass with a 132mm radius. Insert through the holes and trace the ellipses, as shown below.
After cutting the holes out following the elliptical guidelines, use an abrasive disc to prepare the inside and outside surfaces of the hull for laminating (approx. 10 to 15cm around the holes).
Position the tunnel in the hull, mark the positions of the different components, as well as the areas that require laminating, then remove the tunnel. It is advisable to drill the tunnel before laminating it into position. See section 3 “Composite Motor Support and Drive leg” for more details.

Replace the tunnel. To secure its position apply reinforced fiberglass filler to all areas, both inside and out, taking care to entirely fill the space between the hull and the tunnel. Laminate using a minimum of 8 layers of ISOPHTALIC RESIN alternated with mat and roving.
In difficult to access areas (i.e. under the tunnel), it is possible to only apply reinforced filler.
Once the filler has set on the outside, finish with a waterproof under coat, followed by sanding and application of a waterproof finish coat.
In order to optimize the flow of water whilst sailing, and to avoid turbulence due to the tunnel, leave 1 to 4 cm of Finish these with several coats of reinforced filler in order to obtain the required hydrodynamic lines.
Once all laminating work is complete, apply a watertight barrier.

DO NOT LAMINATE THE AREA OF THE TUNNEL TO WHICH THE ELECTRICAL MOTOR

SUPPORT WILL BE FIXED.

3. COMPOSITE MOTOR SUPPORT AND DRIVE LEG

** The motor support and the drive leg must be centered in the tunnel.
Locate and mark the intended position of the holes for the fixing screws and the leg hub. You can use the motor support and the leg’s gasket to mark these holes.
In some cases, it will be easier to mark and drill these holes BEFORE laminating the tunnel.
After drilling, use the gasket to verify the holes’ axes and adjust them with a round file where necessary.
These holes must be completely clean before inserting the screws.
Position the leg, the gasket ( between the leg and the tunnel** ) and the motor support, and then tighten the two screws alternatively. Finally, mount the propeller(s) to control the general alignment.
If the general set-up is correct, remove the propeller(s),the leg and the gasket.
Apply a thin coating of silicon grease or sealing compound to both sides of the gasket (this must be resistant to hydrocarbons and water). Re-assemble all parts as before, positioning and then tightening the two 10mm Æ screws alternatively, using a 6mm Allen key, (maximum torque: 35 Nm).
Check that the propellers rotate freely, without resistance or friction.

It is imperative that the holes and the screws remain free of sealing

compound, otherwise there is a risk of an incorrect assembly of the parts.

**Caution: do not use graphite grease. NOTE:
** The composite drive leg:

• is pre-filled with oil and sealed for life
• does not require anodes
• must not be disassembled, even partially (exclusion warranty)

4.  ELECTRIC MOTOR

The upper coupling (motor side) is adjusted in the factory. Position the lower coupling on the drive leg shaft and push it down as far as it will go (lightly grease the shaft beforehand).
Place the flexible red coupler on the drive leg side coupling, (part n° 8 on the CT165 / CT225 – Spare Parts diagram, page 13)
Now fit the electric motor onto the motor support and tighten the four 10mm Ø motor support screws alternatively (maximum torque: 40Nm).
Push the lower coupling up into place using a screwdriver et tighten the two 4 x 10mm Allen screws (maximum torque: 10Nm).
The upper and lower couplings must be adjusted to leave 2mm of play (+/- 1mm) between both of them.
Check that the propellers turn without resistance (a little resistance due to the motor is normal).
Ensure that air can flow freely to allow the motor to cool whilst in operation.

Please note that the motor side coupling is already in position and does

not need adjusting.

2. PROPELLER

Insert the drive pin and propellers.
Check that the propellers turn without resistance (a little resistance due to the motor is normal).

Position the propeller blades so as they are not in horizontal alignment

and not directly opposite each other.

Tighten the 22mm nut (maximum torque: 25Nm).
Protect your hands during this operation to avoid risks of injuries caused by the edges of the propeller.
IMPORTANT: to prevent against calcium deposits that damage the seals, we recommend that you coat the shaft and stainless steel cover with silicon grease.

5.PROTECTION GRIDS

It is possible to install protection grids, however, their installation may affect thruster performance

6. ELECTRICAL INSTALLATIO

CAUTION: an incorrect electrical installation will cause rapid deterioration or even failure of the thruster. Excessive voltage drop will cause premature wearing of the relays and brushes. Special attention should be given to the quality, capacity and condition of your batteries, as well as cable sections used. Last but not least, the installer is responsible to protect the electrical components of the thruster assembly against direct water contact.

Ensure that all electrical connections are correctly tightened.

Under no circumstances should any flammable products be stored next to the electrical components of the thruster.

It is essential to install a manual battery isolator and if possible an

electric battery isolator at the base of the thruster motor power line.

When using a manual battery isolator, it must be visible, clearly marked & easily accessible.

Thruster motor power supply (24V):

These values are given as an indication, assuming that the batteries are charged at 100% and in charge, that is 25.4V.
The performance data is measured with an approx. consumption of 560A and 22V for the CT165, and 690A and 22V for the CT225, at the motor’s connections.
Please refer to the characteristics given by the manufacturer of the batteries that will be used (see section 9 “Batteries”).

Power wiring:

1. Measure the shortest and most direct route possible between the battery(ies) and the electric motor; remembering to allow for both “positive and negative”
2. The power cables must be located in a well ventilated
3. The material of the cable insulation should be from PVC and with thermal rating 105 degrees Celsius and above.

Recommended cable sections:

For all connections, use M10 terminals for the cable sections chosen.

It is possible to reduce the cable section to facilitate easy connection but only over a short distance. In this case, appropriated crimp fittings should be used at the connections.
Please consult the “Electrical installation” diagram p. 11 for more information

__ 8. MAIN POWER FUSE

Fuse sizes for over current protection are to be determined on the basis of the cable sections in the circuit and NOT the amperage drawn by the appliance (thruster motor) in the circuit.

Thruster Model| Maximum Amperage| Max Power Ceramic Fuse| Max Power ANL

Fuse

---|---|---|---
CT165| 560A| 250A| 325A
CT225| 690A| 250A| 400A

9.BATTERIES

Thrusters are high amperage consumers with instantaneous demands, thus, we recommend you use maintenance-free “starting” type batteries, with high CCA outputs. For example: Exide Maxxima 900, 12V, capacity 55Ah / starting current 800CCA. For CT165 is needed 1680CCA total output and for the CT225 model 2400 CCA total output (100 Ah needed for 10 min/day for the CT165, and 120 Ah for the CT225). In case of lithium batteries, the amperage drawn by the thrusters must be regulated not to exceed the maximum amperage. If the dedicated batteries are charged by the alternator, the reference of the charge must be taken after the diode-splitting block (if in doubt, consult a marine electrician).

10. ELECTRONIC CONTROL BOX

Install a fused circuit breaker / switch in the boat’s main DC distribution panel marked BOW THRUSTER. This circuit breaker / switch should ideally be supplied from a different battery bank to the one used for powering the thruster.
The supply to the control box must match the nominal voltage of the main relay and battery isolator.
The installer must protect the positive supply cable of the thruster’s control box by means of a 8A fuse. The size of the power cables (red & black) depends on the length of the cable run, the voltage drop in these cables should not exceed 5% of the nominal battery voltage.
For safety reasons, and in order to obtain all the functions provided by the thruster controller, an electric battery isolator needs to be installed in the thruster motor positive supply cable. Max Power advises the use of an electric battery isolator ref. 318401 for CT165 and ref. 634424 for CT225.
If an electric battery isolator is not used, then simply seal-off the two grey wires coming out of the control box. It is important to isolate the thruster motor power circuit by means of a manual battery isolator after having used the thruster.
Please refer to the drawing “ Relay and control box connections ” p. 12 for more detail on the wiring of the control box to the thruster.

11. CONTROL PANEL AND THRUSTER CONTROL BOX FUNCTIONS

**** To switch the thruster ON or OFF follow the instructions given in the diagrams on the following page.
When switched ON the control panel will beep once and the green LED in the red push- button will light up.
When switched OFF the control panel will beep twice and the green LED in the red push- button will go out.
The thruster controller provides a time delay between left and right thrust in order to avoid rapid direction changes. There is no delay when thrusting to same side.
If the thruster motor overheats the control panel will start beeping and the green LED will flash until the thruster motor has cooled down.
As soon as the overheating alarm sounds, there are 10 seconds of actual thruster use before the unit automatically shuts down. It will then not be possible to switch the thruster on until the motor has cooled down.

If the thruster has not been used for a period of thirty minutes it will

automatically switch itself off.

** Before switching off automatically the control panel will beep once followed by a second beep a few seconds later, after which the thruster switches itself off.
In order to isolate the thruster motor power circuit, as described in the previous two paragraphs, it is necessary to install an electric battery isolator, as advised by Max Power.
Please consult the “Electrical installation” diagram p. 11 for more information**

Control Panel Instructions

12.CONTROL PANEL INSTALLATION

**** Control panels should be protected from the natural elements while the thruster is not in use.
Install the control panel(s) in easily accessible positions, without obstructing the main engine and/or steering controls.
When fixing the panel with the stainless steel screws, make sure to install the pre-cut rubber seal, as supplied with the panel, ensuring that it is in the correct place.
Only when totally finished and satisfied with the wiring and positioning of the unit, clip-on the face panel/cover.
Please note that panels are only fully waterproof from the front, if installed correctly. However, the area behind the dashboard should be kept dry to avoid the risk of oxidization of the cable connecter contacts.

For full control panel installation instructions, please refer to the

“Installation Guidelines” as supplied with each control panel.

TESTS
Activating the thruster when the boat is out of the water is not advised under any circumstances for safety reasons and because it could damage the motor.
Tests must be carried out with the boat in the water, the battery(ies) charged at 100% and in charge, and the engines running.
The maximum continuous operating runtime corresponds to S2-2.5 minutes’ norm. However, this can be affected by the ambient temperature.

14. ELECTRICAL MEASUREMENTS

In normal “usage” mode, i.e. thrusters running, boat in the water, with fully charged batteries under ongoing charge (alternator), electrical measurements should be made at the following points: At the batteries
At the battery cut-off switch
At the fuse
At the electric motor’s connections
At the power supply arriving at the thruster control box
These measurements will enable you to detect voltage drop.
NOTE: the voltage reading between the motor’s negative and positive connections
should be approx. 22V for a 24V system.
The cumulative effect of voltage drops at these points can severely impair the thruster’s performance.
Should the voltage measured be too low, the following points need checking:
Are the batteries of sufficient capacity?
Are the batteries good quality?
Are the batteries sufficiently charged?
Are appropriate cable sections being used?
Are the connections sufficiently tightened?

15. OPERATION

With the control system circuit breaker/ switch and manual battery isolator switched on: Switch on the control panel, as previously described in the manual. Push the red button or incline the joystick to the left and the boat moves to the left. Push the green button or incline joystick to the right and the boat moves to the right.
If, during tests the boat moves in the wrong direction, change around the blue and the brown wires on your power relay.
When maneuvering remember that the boat’s momentum continues after you release the joystick / button, therefore remember to release the control prior to reaching your desired position.
Care must be taken not to use the thruster in areas where there may be people swimming or floating debris.
Maximum running time: 2-3 min (depending on ambient temperature).

16. ALARMS OR THERMAL SWITCH-OFF

The thruster’s electric motor is fitted with a thermal switch as standard. If the thruster motor overheats the buzzer in the control panel will start beeping and the green LED in the red-push button will flash until the thruster motor has cooled down again. As soon as the overheating alarm sounds, there are 10 seconds of actual thruster use
(5 intermediate beeps) before the unit automatically shuts down. The unit will then not be able to be switched on again until the motor has cooled down.

17. SAFETY

Switch off means to cut the power at both the DC equipment panel (control power supply) & the thruster battery isolator (thruster power supply) after having used the thruster.
Under no circumstances should any flammable products be stored next to the electric components of the thruster. Care must be taken not to use the thruster in areas where there may be people swimming or in the water close to the thruster.
CAUTION: Never tamper with the thruster / thruster turbine if not 100% sure that both the control and power circuits have been isolated, except if taking electrical measurements on the thruster motor or relay.

18. MAINTENANCE

Control panels should be protected from the natural elements while the thruster is not in use.
The thruster requires a minimum of ongoing maintenance:
Check the condition and charge of the batteries regularly, as voltage drop is the most frequent cause of rapid deterioration of the relay.
Carry out a regular check of all electric components: batteries, connections, power cables.
Remove the motor and clean out dust from the motor-brushes with compressed air.
The electric motor must be kept dry and well-ventilated.
NOTE: All maintenance should be carried out by qualified and authorized personnel.
Composite drive leg and propellers:
The composite drive leg is pre-filled with oil and sealed for life. It does not require the oil changing.
The composite drive leg does not require an anode.
The composite drive leg must not be disassembled, even partially (this would void the warranty)
When the boat is out of the water, check that there are no fishing lines, plastic bags, etc. caught in the propellers.
Paint the drive leg and propellers with antifouling (make sure that they were well prepared and primer has been used).
Always keep the propellers and tunnel clean.
To prevent the buildup of calcium on the drive shafts, which would damage the oil seals, cover the drive shaft and the oil seals’ stainless steel covers with silicon grease before fitting the propeller(s). This should be done on an annual basis after the cleaning of the outside of the leg. Do not use aggressive solvents as they may damage drive leg seals.
If drive leg oil seals are found to be worn, replace the drive leg with a standard exchange unit.
