Schindler PEBO fault

Hey guys, I'm getting a constant lowbatPEBO fault every day or so on this MX GC.

Ive replaced the batteries and have done multiple resets.

Any help on how to disable / remove this fault?

Thanks.

Change the battery for the emergency rescue operation.

Hi there,
i have same issue , any solution please?

"heisenberg" did you manage to solve the problem?

I forgot to say that i measured the baterries on PEBO rescue device, there are 4 batteries , 3 are in referent values from12.2V - 13.1V, but 1 was 9.7 V. so i replaced that one and had lift working for one week.
But after one week the lift stoped with same error "batlowPEBO", so i measured the new battery i replaced a week ago, and the result was 10.1 V i think the issue is with battery charging.

Solved the issue with adding additional stand alone battery charger directly to battery which does not charge, and everything works for more than 3 weeks.

Basically on my unit there is a UPS device in the headroom of the lift shaft, it charges two 12v batteries wired in series

The UPS has an internal dry relay contact that closes when the UPS internal battery is good, however when the battery in it becomes faulty, the contact will open.

When the contact is open, the ASIXB main board IO plug pins number 1 and 4 are no longer connected, giving the pebobatlow fault.

If you follow your electrical schematics correctly, you'll see that io.1 is 24vdc output and io.4 is your pebobatlow signal, when it's not receiving 24vdc, you'll have the pebobatlow fault.

Either your AXISB board is not giving out 24vdc correctly, your NGL power supply is too low or your UPS is not closing the required contact.

Well , thank you "heisenberg" this is nice explanation, as i have no experience with schindler your post is very useful for me.
Cheers mate

Glad to help!

You're shorting those contacts and still getting pebobatlow error?

I had this fault before, there was a fault on the GCIOCF board (the board with the reset button)

My board was physically damaged

Pebobat fault would not clear! Super frustrating

Once I got a new board, the fault went away.

Yes pebobatlow frustrates me for 2 days, damn battery charger does not charge bateries.
