Display Mode 2: Flashing L.E.D. This indicates that the temperature sensor has picked up the battery temperature exceeding 50 degrees C. This usually means that the battery is defective and on it’s way to boiling. Check the voltage across the battery, if below 14 volts and 50 degrees C then the battery is defective. Replace as soon as possible.
f:Tri Coloured L.E.D: This simply displays the battery type that the processor has been set to. All information regarding this is on the label.
g:Red L.E.D Battery Negative Trip Fault: This alarm shows that there is a fault on the negative between the battery negative and the alternator negative. This is usually due a bad connection. Please clean all connections and check cable crimps etc.
h:Green High Alternator temperature disengage: This shows that the alternator temperature sensor has exceeded 90 degrees C and has automatically disengaged the Advanced Regulator. The regulator will automatically re- engage at 65 degrees C. This process is fully automatic and requires no intervention. If you find this trip working a lot of the time, I suggest you check your engine room cooling and I would recommend a fan cooling system, blowing cold air from outside onto the back of the alternator (alternators suck air from the back through themselves to the front).
i:Yellow 12 volt system setup: This shows the system is set to 12 volts, it cannot accidentally be set to 24 volts or jump to 24V itself as an internal link must be made. Please ensure this is on if your system is 12 volts.
j:Green 24 volt System Setup: This indicates that the system is set up to 24 volts only. Under no circumstances should the device be run in this mode if your system is 12 volts as all the trips will be set to 24 volts This will result in the destruction of your batteries with no warning given.
All L.E.D’s flashing: The most common fault, this shows the alternators voltage has exceeded 17.5 (or 37 volts in the case of 24 volts). This happens for various reasons such as cables from the alternator to the battery are too long and not thick enough to carry the current or if there is an amp meter in the circuit then usually there is a problem with the connections to the amp meter. If an installation has been running satisfactorily for a period of a few weeks and this starts then check if the split charge relay or diode is OK and has not failed. Please note that when this, or any trip light is on the Advanced Regulator has been electrically totally isolated from the alternator and is no longer in use. If the alternator voltage continues to rise after this has tripped then please check the alternators own regulator .and stop and disconnect the alternator
Alternator Temperature sensor see fig 3 part a
This sensor connects to the alternator and in the event of the alternator case or diode pack (depending on where it is connected) exceeding 90 deg C then the Advanced Regulator will DISENGAGE (ie switch off the high charger rate) until the alternator reduces its temperature to below 65 deg C, then the Advanced Regulator will
Where to fit.
The best place to fit this sensor is to connect it by a jubilee clip directly to the exposed stator of the alternator if possible however some modern alternators enclose the stator making access to the stator impossible, in that case the best you can do is connected it to the main B+ terminal which is usual connected by a copper bolt direct to the diode pack.
In a well ventilate engine room this feature is normally not required and was only added as a after though for sailing boats in hot climates with heavy sound insulation. Always remember that this only disengages the Advanced Regulator but cannot prevent your standard alternator’s own regulator from over heating the alternator The temperature sensor is isolated and also has no polarity preference, ie the red and black cables do not donate pos and neg.
The temperature sensor cables can be extended
Please note that in the interests of safety, (unlike other companies) if you do not wish to use any temperature sensor or if one of the cables become broken or disconnected, the software program will detect this within 2 seconds of the fault and default to the standard safe settings.
