Sterling Plumbing BB122430, BB121250 manual LED meanings and functions fig8

If on start up nothing happens, 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.

Auto pause switch off. 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.

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

The LED meanings and functions fig8

14BATTERY 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..

15ALT 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.

16CONSTANT 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.

17TIMER 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.

18FLOAT: 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.

19BATTERY 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:

please take this warning very seriously and stop your engine as soon as possible, remove the alternator input cable then continue your journey and have the alternator repaired.

20BATTERY 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

21BATTERY 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

22BATTERY 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.
