Wiring diagram for tree mill, 2UVR-C
https://drive.google.com/open?id=12jTR94KAUqKY2gYvy3mrepb9yzLimgbk
I have real 3 phase power. Both Feed Motor and Head Motor are somehow mis-wired. Both run fine, but I cannot turn them on-off with the switches. Start-stop switches have been checked and work properly. I have tried all 6 possible combinations of hooking 3 wires to 3 terminals. In ALL cases both motors run when main power is turned on. In two of the configurations a push of the momentary OFF switch stops the motor but it restarts when released.
I am thinking that there is a bad connection somewhere in the contactor and not in the ON/OFF system.
Below are some of the voltage readings:
L1-L2 240V L1-Ground 218V 2-Ground 0V
L1-L3 240V L2-Ground 121V 3-Ground 120V
L2-L3 240V L3-Ground 120V 2-3 0V
L1-2 0V L1-3 248V
L2-2 0V L2-3 242V
L3-2 0V L3-3 0V
Any help would be greatly appreciated. Otherwise I am running the mill by wearing out the main power strip.
