Home Forums General Discussion Technical Questions Fault 0169 ( KCM 831 )

Got this fault that keep coming back 0169 , I check the voltage coming from the batterie , I have 13volts , I reset it but it the fault come back again ? any suggestion ?
Thx

the battery should be connected to the ccbn board at XB32. The LCE runs a battery test every 24 hours. You should have a battery ok light on the car top ccbn board. you could have a bad connection if the battery is charged.

I notice the battery light is Not on ? I check the connection all good , I'm suspecting the board ?

change the battery anyway.....even if it tests ok.

Ok I install a new batterie and everything is back to normal , I dont understand the old batterie is still giving me 13.5volts ?Anyway thanks

Had the same thing on many occasions, thats why my previous post said to change it anyway.

Hi,
Did you check to see if board is charging the battery?

when you test voltage and suspect a problem, it is a good practice to use an analog type meter such as a simpson. they will put a load on the voltage and give you a truer reading. a digital meter will often give you a false voltage. they are a wonderful tool, but not fool proof. when testing a higher voltage such as 120 volts or higher, a wiggington or wiggy is the truest test.

Yes 0169 fault the car top connection board does a load test on the battery , so even if the battery reads ok by a meter it could still fail , there is also a small resistor pot at the top of the board if you adjust this you increase the charging voltage to the battery , in sydney we find these pots are set to low .

If your lift was still operational while flagging up a 0169 fault then you better check all the relevent parameters as they must be on the wrong settings. 0169 fault should kill landing calls to prevent passengers entering a lift car which has a bad back-up battery.
