If on start up nothing happens,
Auto pause switch off.
WHAT CABLE TO USE IN mm sq
A charger or inverter up to cable run distance 0-1.5 mtr 1.5 4 mtr
0-25 amps 6 mm sq 10 mm sq
25-45 amps 16 mm sq 25 mm sq
45-85 amps 25 mm sq 35 mm sq
85-125 amps 35 mm sq 50 mm sq
125- 180 amps 50 mm sq 70 mm sq
180-330 amps 70 mm sq 90 mm sq
Please note that if there is a problem obtaining for example 90 mm sq cable, simply
Use 2 x 50 mm sq , or 3 x 35 mm sq , the cable is simply copper, and all you require
Is the copper , it does not matter if it is one cable or 10 cables as long as the square
area adds up. Performance of any product can be improved by thicker cable, so if in doubt round up
then
1) test the battery voltage. It should be above 11 volts, to see the unit working start up the engine and ensure you are
getting at least 13.5 volts at the battery.
The units has a automatic program cycle which works 3 minuets off and 20 minuets on etc etc
until the batteries are charger, this cycle is to ensure the engine start system is well looked after and is bias in the engine
starter battery's favour. If you wish to remove the 3 minuet rest period ( which is o.k. and the engine start battery will be
o.k., then simply push button 1 and 2 at the same time ( this can only be done on the remote ) bold the two buttons until
you hear a beep, the screen will then say auto pause off. this will auto reset on system restart.
The LED meanings and functions fig8
BATTERY TYPE Tri Coloured LED: This simply displays the battery type that the processor has been set to. This is a
tri coloured LED. Yellow = open lead acid, Green = gel /sealed lead acid . Red = AGM..
ALT OVER TEMP : Yellow: This monitors the temperature of the alternator and disengages the unit in the event of
the alternator reaching 90 deg C, which waits for the alternator to cool down then automatically re-engages.
CONSTANT CURRENT: Green: This should be on from start up( slow flash shows unit on but on rest mode, for the
first 2.5 min. On start up and approx. every 20 min after, see graph ) and shows that the alternator should be working
at it’s maximum. It should remain on until the green float comes on and this shows the high charge rate is complete.
TIMER ON : Yellow: Timer Activated: This comes on, when the voltage reaches about 13.9 - 14 volts ( x 2 for 24 v )
and depending on how long it took to come, will dictate how long the timing cycle will remain on. The software will
calculate the timing for the high charge rate. This will vary from 1 - 6 hours and the time will be displayed on the
remote panel and a count down . This light will remain on until the high charge rate is over, and will go out at the
same time as the high charge rate between 1-6 hrs after activation.
FLOAT: Green Float Mode: This indicates that all the high charge cycles are now over and should remain on after all
the high charge lights are out. The system is now running at a standard charge rate only (about 14 volts) regulated on
the battery.
BATTERY INPUT OVER VOLTS: This will warn you and switch off the boost section, this means that your
alternators own regulator has failed and the alternator will now boil and destroy your batteries, there is simply nothing
we can do about this except warn you:
a o
t
BATTERY INPUT LOW VOLTS yellow: Low Voltage Warning: This is simply saying that there is a low voltage at
the main battery bank and has no active function. For information only, this usually indicates a defective alternator
BATTERY OUTPUT OVER VOLTS: This will warn you and switch off the boost section, this means that either out
unit has failed and was in the process of overcharging your battery bank, or you have some other charging source on
your output battery bank which is overcharging the batteries and our unit thinks it is out unit
BATTERY OUTPUT LOW VOLTS yellow: Low Voltage Warning: This is simply saying that there is a low
voltage at the output battery bank and that the charing unit is unable to keep up with your demand on the battery bank,
or the unit has failed and is not working.
please take this warning very seriously nd stop your engine as so n as possible, remove the alternator input cable
hen continue your journey and have the alternator repaired.
