I have a Evakool fridge that I believe the cutout voltage is 10.6v. It is running a Danfoss BD35 compressor. I have the spec sheet that says that I can change the cutout to 9.6v by removing a resistor. But I can't find the resistor. It says that there is a resistor between the C & P teminal. I just have a piece of wire with no resistor. It mentions that a value of "0" or "220" will give the cutout of 9.6v and a cutin of 10.9v.
Any help would be appreciated.
Regards

G'day mate,
If you call Evakool on 07 5492 7777 and press number 9 when it rings then ask for Craig he will be able to walk you through the process with ease.
Cheers,
Grossy

Hi
Why wou;d you want to reduce the cutout voltage toTHAT low??
Even @ 10.6 [unless you have a lot of voltage drop in your wiring & if so IT SHOULD BE CORRECTED ] IS A FLAT BATTERY.
IF it is a wet lead acid battery taking it that low will seriously shorten it's life.

Thanks for the replies.
All Evakool fridges now come setup with the 9.6v as standard.
Quote"We are able to
tailor low voltage cut out to your specific requirements. If for example you have dual batteries in your vehicle, we can reduce the cut out from 10.4v to 9.6v giving you around 15-18 additional hours of fridge use.
NOTE : This is only available to fridge owners who purchased their fridges before 2007 as all fridges manufactured after this time have the 9.6V setting."
So I will give them a call.

HI Esplanade
You may get a little more running time out of the batteries BUT very few types of batteries take kindly to being 100% discharged & with 9.6v AT the Battery it is FLAT. Or if you are loosing 2v+ in the wiring then it is inadequate
When you give them a call ask them how it will affect the battery life.
Many of us would be interested in what they say.
What type of battery do you have?

"It says that there is a resistor between the C & P teminal. I just have a piece of wire with no resistor"
In this case the piece of wire is a 0 Ohm resistor.
If you know the required resistance value then just replace the 0 Ohm resistor you have fitted with the required value.
"It mentions that a value of "0" or "220" will give the cutout of 9.6v and a cutin of 10.9v"
It would appear you already have this configuration installed in your fridge.
As I stated above, a piece of wire can also be thought of as a 0 Ohm resistor.

Thanks Geoff.
That is what I thought. It may be that the cut in voltage is being the cause for the fault light. (1 flash)
I guess this will protect the battery as long as the temp gauge is set to allow the compressor to cycle. You will hit the 10.9v cut in min before the 9.6v cut out voltage.
I thought that the battery was above these values though. So I presumed that the fridge was still set at 10.4v.
Thanks for your help.
