So if anyone runs into an IGBT pack from a York Chiller I’ll do you a solid and give you a pin diagram.
York part number: 031-02061-001
The connector is of this style (p/n from package, I forget which side): 1-794223-0 http://www.digikey.com P/N: A100435CT-ND .. using this you can find both pieces.
.. all TTL is 5V the “/” is a low level input designator. PIN
1: U1 (5VDC)
2: U1+U2 /FAULT
3: U4
4: U5
5: U5+U6 /FAULT
6. T1 (RTD 5K)
7. DC NEG
8. Vcc (5VDC)
9. Isolated Power (I think this is 24VAC but I’m not sure)
10. U2
11. U3
12. U3+U4 /FAULT
13. U6
14. /RESET
15. T2 (RTD)
16. N/C
17. DC NEG
18. Other side of isolated input I believe.. I blew mine up before I could fully test this.
… as for the IGBT it’s 2, 4, 6 are + (up to 1.2kV) and 1, 3, 5 are the negative side, the others are the 3 phase output. New, this pack is painfully expensive.. $1,400 but maybe you’ll run into a good deal or some “garbage” as I did. Good luck!
