Yes, typically batteries fail high impedance, but not always (loose lead plates and internal corrosion can cause low impedance failures)- but seeing how there are two in series, you're most likely correct that the impedance is high and unlikely to cause a failure in that direction. Alternatively (again, just stipulating - don't actually have a schematic) a high impedance battery on a current controlled charging circuit could cause a rail to go beyond expected voltage. (Yes, it's a total BS guess- but i'm looking for reasons why [what i think is was a MOV] the component failed). Time and heat can also dry out electrolytic capacitors, but they look fine externally. Power supplies often fail because of inappropriate or damaged loads attached to them, so that was my first suspicion. Open to alternative ideas as well.

tmuthesius I just had the same thing happen to my KRC1. Did you find out what caused it? And were you able to repair it? I don't have a schematic for that board, but I am suspicious that a pair of dead batteries (computer backup power) might have caused too high of a current flow. Looks like that board generates the 27V rails that charge the batteries

Thanks SkyeFire.
Got a better look at the connector, and CC1 should mate with:
- Insert: Harting 09320323101 https://www.digikey.com/produc…3101/1195-1991-ND/3180574
- Pins: Harting 09330006206:https://www.digikey.com/produc…6206/1195-2020-ND/3180603
As per SkyFire's links, and the KUKA KRC1 Datasheet: 00-111-587 (Pg 33), CC1 Connections are:
(1 to 3), (2 to 4), (5 to 9), (6 to 10), (7 to 11), (8 to 12), (13 to 14), (15 to 16), (21 to 22), (23 to 24) and [(17 to 18), (19 to 20)].More to come.

Hi All,
I've got a pair of KUKA KR150 robots with the GM KRC1 Control Cabinets. Looking for some information to get my robots up and running - hoping to put together a "build (setup) log" on the topic once its complete.
Two things I'm stuck on right now:
- CC1 (interlock interface) -> Its a Harting connector, but i'm missing the mate - does anyone know this PN?
- Mouse Pinout -> Can't seem to get the pinout right for the mouse to work. The MotherBoard (SY-7IZB+N) manual doesn't give pinout information. Could someone take a picture of their mouse header wires (2x4 header)
Also looking for resources (Manuals, Datasheets, Anything) on the Key selection ("T1, T2, Auto(EXT)") modes.
Thanks,
Austin
