Hello everyone,
I recently purchased an RF45 clone ZAY7945FG/1 with an electrical issue.
I will start off, I am no guru with AC electrical, but am fairly competent when it comes to DC systems. I figured I should be able to troubleshoot this.
So the machine is wired for 240v, and when the electrical contractors are pressed the motor runs as it should (both forward and reverse).
I’ve tried following the voltage from the outlet into the machine, and it seems to disappear at the CU-11 Contactors (a form of relay I assume?)
There is 23v pretty much everywhere where 120v is not seen (using one side of voltmeter grounded).
I tested continuity at the 3 safety switch I found (protection shield, then two on the quill). They seem to work fine while measuring 23v.
I have no wiring diagram for this exact machine.
transformer shows proper voltage at input and output is also 23v.
There is no sign of 120v in the electrical “button panel (emergency stop etc).” 23v again.
The 2amp ceramic fuse checks out.
Any input is greatly appreciated.
