23BATTERY OUTPUT OVER TEMPERATURE: Red : This shows that the battery temperature sensor has picked up

a temperature in excess of 50 deg C at its source ( where ever you have fitted it ) this will trip the unit until it has been reset. Please find the fault before resetting

24HEAT-SINK OVER TEMP. yellow: This device monitors both heat sinks and in the event of that exceeding 75 deg

C the unit will switch off until the temperature has been reduced. It is important not to fit the unit inside a hot engine room

25DEVICE FAILURE: red: this feature will give an indication in the event of a

Fig 1:This is the most common and easy installation because of being simply connected to the starter battery. In order to connect up the d/c battery charger all you need to do is connect one wire from the auxiliary battery banks to the starter battery. The starter battery stays between 13-14 volts ( within its limits ) and the domestic battery goes up to 14.4.-14.8. In order to put a good fast charger into the auxiliary batteries, this is especially good if the battery bank to be charged is not close to the starter battery , such as things like bowthrusters, or batteries in the boot of cars or lorries

Fig 2 :This option shows a standard split charger system on any boat or camper vehicle, which is already installed, and has been using advanced alternator regulators or any other advanced charging system. An extra battery bank is required such as a bow thruster, radio battery bank or a generator, for ease of installation simply drop on a d/c battery charger.

Fig 3:This option shows a situation on many boats or camper vehicles where there may be 3 x battery banks, simply put 2 x d/c battery chargers on, and they will ensure both banks are catered for, with no problem. the fact that one battery bank is further away than the other will make no difference.

Fig 4 :This option shows a standard split charger system on any boat or camper vehicle, which is already installed, and has been using advanced alternator regulators or any other advanced charging system. You will find out, that you wish to supplement the marine house battery bank by charging with as many other auxiliary charging systems as you can. For example: if you are running a gen set for 4 hrs per day you may as well put as much power as possible into your main large house battery bank

Any source can be used. You can even use this system to charger from a old type battery charger , for example if you had a old constant voltage battery charger and you wished to convert it into a constant current one, then simply put one of these on the output. Or if you have a single output charger and want a dual output, then simply add one d/c charger to make a dual charging system

Remote control panel see fig 5

A: on/off: this switches off the unit boost aspect, but cannot prevent the standard diode splitting from working. The monitoring functions remain in and the only way to know if the unit is switched off is the system within limits ( LED )which will be off while the boost off will be on screen 3b

C:

D:

E:

Alarm: this mutes the alarm system

Back ground light: this switches on and off the back ground light

Green LED, system all o.k.

Low battery input voltage

F: system disengaged, this is an auto recoverable alarm , such as a high alternator temp trip. This will come back on when the temperature has reduced

G:This is a fatal alarm trip, such as high input/output voltage or high battery temp, this will alarm and switch

off

Screen display on remote panel fig 6

Screen D/a: BUTTON 1 This is the default screen. It will automatically display switch on. This screen is designed to display the most relevant information on one screen, to remove the need to flick between screens. This screen shows the battery in- and output voltage. It also shows the amps in the unit, and its state of charge, ie bulk charger ( on start up ). Pause is when the unit switches off for 2.5 minutes, and the time will show ( count down ), how long one has left before the cycle is complete and the unit goes onto float.

Push Button 1: screen D/b this shows the total time, the unit has been running ( ON ) and also the total time, the unit has been charging in that time ( charge )

Screen E/a: Push button marked 2 , this shows the voltage on the input battery and its input current, which is the one the system is taking the charge from )
