Instructions
Look at the Haas Control Remote Input. Take out the cable line from the back of the control. Set the control to 90 degrees. Connect a voltage meter at low ohms across pins one and two which are labeled as "Finish Signal" on the back of the control. If the control remote input is working, there will be an open circuit. If there is no open circuit, the relay is defective. Connect pins three and four together using a jumper wire. The three and four pins are labeled as "Cycle Start." The control should index and the voltage meter should exhibit low ohms. If it does not index or show ohms, there is a problem with the remote.
Check if there is a problem with the interface cable. Look at the signals from the Haas CNC using the voltage meter. You should see that the pin direction is reversed. Perform the M function from the mill to rotate the pin in the correct direction. The start light should appear on stay in the "ON" position.
Check the Haas Control and the Mill at the same time. Press the reset button to reset the mill. Connect the remote cable and turn on the rotary unit. The rotary unit should remain on. If you notice that the rotary unit moves, there is a problem with the cycle start signal from the mill. If the rotary unit remains on, perform the M function from the mill to index. If the rotary unit does not move, the mill is the problem and it is not outputting a signal, or there could be a break in the cable. If the rotary unit moves properly, make sure the mill Cycle Start light goes out at the end of the moving. If the light remains on, the Cycle Finish signal is indicating that there is an open wire somewhere in a cable.
