Series / paralell switch box intallation manual 1.0 - 2002

The switch box works like this

When the thruster is not running: (see FIG.1)

The two batteries (battery banks) are connected in paralell so that the extra battery is being charged by

the boats normal 12V charge system, the same charge system that is charging the standard Batt.1.

By this, the extra battery (Batt.2) becomes a full part of the Batt.1 bank and thereby also increase the

capasity of this.

The box is built so that you can draw the

same amount current from the extra

Batt.2 as the thruster draws as the

solenoids have the same capasity in

their inactive position as in the active

position.(and basically nothing on a

boat draws as much as a thruster).

There is no power on the main positive

lead to the thruster until the thruster is

activated by the controlpanel.

The power to the thrusters

controlsystem and panel is supplied by

the series/paralell switch box, via the

grey and black leads to the control side

of the thrusters solenoid only.

Both batteries are now at 0V - 12V

When you run the thruster: (see FIG.2)

When a run signal is sent to the thruster from the panel, the solenoids in the series/paralell box reacts

first so that Batt.2 is moved into a series connection with Batt.1. so that there is 24V on the main

power supply cable to the thruster.

The main contactors on the thruster

does not engage until this have been

done so that you have 24V at the

thruster to control the 24V main

solenoid contactors on the thruster.

Now, only Batt.1 is being charged

while Batt.2 can only draw from its

own capasity.

In this position, Batt.1 is 0 - 12V and

Batt.2 becomes the 12V - 24V

portion of the 24V feed to the

thruster.

Batt.2 can only be connected to the

series/paralell switch box as

described in the manual.
