I'm sorry if I'm breaking a forum etiquette rule. I'm not able to change the original title of the thread I created and its not very descriptive. Its not my intention to start multiple threads for the same problem.
I have a rather large saw. Its a Pehaka horizontal saw from the mid 80's I would guess. I do not have a schematic for the saw. I emailed the maker in Germany and they said they would send me a manual. Its been several months since they said they would send the documents.
The wires for the solenoids are in a bit of a mess.
I have a slight idea of how it operates.
Turn on the hydraulic pump motor, hit the raise or lower switch for the solenoid and the saw arm would either raise or lower.
If the saw arm went too high it would hit the limit switch and disengage the raise solenoid. Same thing with the lower solenoid, although the saw arm will lower under its own weight if the "lower" solenoid is engaged. If neither solenoid is engaged and the saw is in the raised position it will hold in place. The hydraulic pump can be on and neither solenoid engaged.
I have created a diagram of the way it is wired up presently.
The "saw motor on", "saw motor off", "hydraulic pump on", "hydraulic pump off" all work.
The relays are all magnetic coil types activated by 24VDC that comes off a rectifier. The switches are marked NO and NC.
Some wires I could not trace.
I would appreciate any help I can get with this project. Its been 14 months since I got it and I would like to finish it.
