I'm trying do fix a door operator (Kone Uniswing Operator) for a public association which takes care of disabled people.
It mainly consist in a dc motor powered through a full H bridge and controlled by a single chip 16 bit microcomputer (M16C/62P family)
First investigations show that the motor is ok, power rails are clean and micro computer does not seem to be fried (correct control of the 1 digit display)
I have to look deeper and therefore desperately looking for schematics and service manual
If someone could help me it would be deeply appreicated
ps : the little story. The maintenance guy from Kone came and after a while said that nothing could be done except replacing the door operator by a new one : 3000 Euros ! (the complete door had been purchased 4 years ago for 4000 Euros)
Thanks by advance
