Euro 46 psu battery fault

[Mark Rider]

Hello 

so have had a euro46 for last 3 years installed by my self all been fine 

then all of a sudden got faults fault is Battery fault , PSU fault , Low volts, battery critical 

 so i measure volts on psu thats 20v AC and battery is 13.4 volts so there all good 

so not sure why its gone faulty 

screen shots of UDL software attached 

got no idea where to go now 

strange thing is the UDL software isnt showing the volts or current

any help is good thanks very much

What makes you think just because volts ok battery is good , your forgetting something.....

 

Average battery life is done

as i have checked the battery. drop test etc powers other stuff ok as well

for got to add the control panel also says the psu power is below 10.38volts

Cool your ok then , don't need a PSU don't need a battery 

 

Sorted 

As said 3 years is enough for battery in my.opinion , perhaps it's damaged your psu

 

I doubt you have a battery drop tester for this type ?

[Mark Rider]

??? how can it be ok then if it has a fault because of low power ?

Was being sarcastic..... Just forum banter dude , your still ignoring the battery has been running for charging for three years and it's the first thing to swap out , but you say you measure good voltage from PSU but panel reports low voltage 

 

I would say your testing things wrong somehow but it's all hear say as we can't see what you do 

 

Change battery , failing that psu

[Mark Rider]

ok lol

well im a High Voltage vehicle tech so know how to measure current and voltage so thats not a problem. 

So do you know what voltage should be coming out the PSU ? 

also when you disconnect the battery the alarm sounds which it didnt do before but if you turn power off it shuts down with no battery back up .

The "black act of alarm monkeying"

 

Diagnosis with out tools-

 

Unplug & shake the battery , does it rattle like a skeleton having a wank in a biscuit tin ?

look at the current reading displayed  on the keypad is probably gonna be 1000mA + ?

remove one lead form battery is probably gonna be 450mA

it may well be warm & sooty in the endstation

pull the battery fuse on the pcb you'll probably get 100 Battery Fuse failed or similar on the display in day mode (proves the fuse is good)

 

When you pull the mains & The system just dies

Battery fuse

Battery 

Or endstation pcb

 

Pull a known good battery in & repeat

 

Diagnosis with a multimeter-

 

A battery has a float charge of less than 100mA an uncharged battery say 1000mA, measure the current you should be able to watch it fall to float charge, 

 

Transformer kicks out 20vac, 

The battery leads will either measure nowt or around 14vdc depending on product with no battery fitted

 

Proper alarm co.

 

will have a battery tester & current reading of the system in day & alarm

*art, but lol otherwise.

well i have a battery tester and have tested it like i said and its ok 

 No wonder people dont use professionals as there all as arrogant as you.

as i said i have all the tools just wanted some advice as not fully up to speed on alarms 

as i work on 800v Porsche Taycans
