5. he fuses except one are monitored by the system If a fuse blows the display goes into alarm mode showing which fuse is blown In order to be able to easily replace a blown fuse the panel should be mounted so that the back of the panel is readily accessible The Control Panel is usually used together with the Power Distribution Board but it can also be used by itself In this case external relays are needed to control high current devices such as a water pump or high wattage lights Back of Control Panel The Power Distribution Board The Power Distribution Board is used as junction box It connects together the wiring from the battery charger booster tow connector 12V outlets fridge kitchen bathroom tail light ramp etc It should be mounted close to the caravan battery in order to minimise voltage drop The board is fitted with relays which are controlled by the control panel The relays are used for switch the charging and the fridge supply to the tow vehicle switching on the water pump and for switching on the parking lights when the tow vehicle isn t connected Power Distribution Board 5 Operating the System User friendliness and reliability has been paramount in the design of the system it s therefore very simple to operate There are no complicated setup procedures just push the main switch and the system is ready to go The only two things that are user adjustable are the Time Date and the Display back
6. hen a tap is opened If the caravan has an external water supply connection the water pump is generally not needed when connected to external water supply at a campsite The pump can then be switched off to prevent it from running as soon as a tap is opened 10 11 12 Built in svvitches for external lights The Control Panel has tvvo svvitches external lights These are normally connected to the main outdoor light and to the cargo hold light respectively This saves the user from having to search for a light switch in the dark Ability to use the Parking Position lights without the tow vehicle connected The Parking light switch on the Control Panel allows the Parking Position lights to be switched on without the tow vehicle being available This is very useful if the caravan is parked by it self close to traffic in the dark Automatic switching of the power from the tow vehicle When towing the caravan charging of the caravan battery and the fridge is powered from the tow vehicle s alternator This is accomplished by activating relays Rei and Re2 on the Power Distribution Board The relay control signal should be connected to a power source which is activated by the tow vehicles ignition switch In northern European countries this achieved by connecting it to the parking light which comes on automatically when the car is started When the tow vehicle is stopped the relays then disconnect the supply from the tow vehicle in order
