The Alarm connector J3 is connected as follows: pin 1 goes to pin 6 of U208 pin 2 goes to pin 5 of U208 pin 3 goes to pin 6 of U207 pin 3 goes to pin 5 of U207
U208 (and eventually U207) are labeled 207a. This leads to IL207 from Siemens which is an optocoupler. Pin6 of this is collector and pin 5 is emitter. Pins 1 and 2 are laser diodes.
All other pins of J3 look nc. cheers Götz _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
