ALARMS:
THE UNIT IS FITTED WITH A LOT OF ALARM AND SAFETY FEATURES.
UNDER NORMAL RUNNING THEY SHOULD NEVER COME ON.
THE ACTUAL ALARM WILL REMAIN ON THE SCREEN.
IN THE EVENT OF SEVERAL ALARMS HAPPENING THEN
THEY ARE PRIORITIZED TO SHOW THE WORST ONE
THE ALARM BUZZER CAN BE SWITCHED OFF BY
PUSHING THE ALARM BUTTON ON THE REMOTE CONTROL,

MAJOR FAULT ON THE
DOMESTIC BATTERY BANK
Cable thickness is very important to avoid to much voltage drop at high currents. This could lead to a fire in the
cable its always a good idea to test the unit at full power and feel all the battery cables, if you have problems
touching the cable then the temp will be in excess of about 50 deg C and this is getting to hot, add more cable
to reduce the v drop and the temp will also drop
The usual only way this can happen if the alternators standard reg has failed and to much voltage is being
produced at the alternator, this is a serious event and requires the engine to be switched off as soon as possible
to prevent damage done to the system, we cannot stop this, only warn you. if you are somewhere where you
cannot fix this problem, then please stop the engine as soon as possible and remove the alternator output
cable or the alternator drive belt before continuing on . sort the alt as soon as possible
The usual only way this can happen if the alternators standard reg has failed and to much voltage is being
produced at the alternator, ( as above ) however its possible the alternator is ok but the alt to battery charger
regulator has failed in some way and its going to damage / over charge your batteries, in this case when
the trip is activated the voltage should drop down to within safe limits ( about 14 volts ) the unit is then defective
This fault is intended to show high battery temp in excess of 55 deg c, however other factors can trigger this
alarm, for example a large amount of current going through loose/ small cable can cause the temperature on the
battery stud ( where the temp sensor is connected ) to over heat, this can set the alarm off. so in the event of this
alarm activating, visit the terminal in question as soon as possible ( within a minuet or so ) and confirm if the batteries
are hot or simply the terminal, in which case fix the terminal/wiring to stop this
This fault is intended to show high temp at the alternator, if this keeps going off then you should consider piping
cold air in around the back of the alternator, the alternator will then suck the air from the back of the alt through
to the front , this will dramatically cool the alt down
There are 3 internal temp sensors controlling the fans inside our unit, in the event of one of them failing then this
alarm will sound, it would be a good idea to return the unit for service
This is the first stage warning that the voltage drop down your main domestic cable between the unit and the
domestic batteries is getting to much ( assuming the remote sense wire is connected ) and you should be
looking at increasing the amount of copper on that run of cable ( ie double it up ) . if the voltage drop goes
over 1.8 volts then the unit will trip ( see above alarm )
This alarm is as it states, the unit is getting to hot and has switch off, make sure the unit is in a ventilate space
and reasonablely cool, not in a engine room or a sealed cupboard. You may need to reposition the unit
This is just a pre warning saying the unit is getting into a uncomfortable condition but is still working and has
hot as yet tripped out yet
Hard to say what would cause this, a alternator reg failure causing a high alt voltage would but then i would expect
other alarms to go foo first, another possibility would be another charging source causing the problem , maybe
a solar or wind gen or a battery charge has failed open circuit. check the alt voltage
This fault could be caused by a excessive load on the starter battery or a alternator failure
This alarm could be as a result or the alternator failure ( check alt voltage is above 13,3 volts ) if so then
you could simply have a heavy load exceeding the ability of the system to sustain that load, the problem
will resolve itself when the load is relieved, and the system given a chance to recover .
I would say the most likely problem here would be the alternator failure, or possible such a large load
on the system the alternator has collapsed. remove all large loads and see if the alternator recovers , if
not then the alternator has failed,
this would be a catastrophic short circuit on the domestic batteries, fix as soon as possible
