Electrical Installation - Tormach ATC Operator's Manual

1.
Remove the four column cover plate screws from base
of column at the back of the mill. The Z column cover
plate will be replaced with the ATC control module.
Save the screws.
2.
Lay the ATC control module plate with solenoid
side down on the chip tray or the Y axis bearing box
temporarily.
3.
Remove the power draw bar electrical housing (Z axis
motor connection box cover plate).
Note: If you purchased a Power Draw Bar before
June, 2011, you may need to change the Power Draw
Bar control circuit board.

3. ELECTRICAL INSTALLATION

Circuit boards labeled Rev 1.2 will need to be replaced. In
this case Tormach should have included the updated circuit
board with your ATC.
Circuit boards labeled Rev 1.3 and higher do not
need to be removed from the housing.
•
To replace an old (Rev 1.2 or earlier) circuit board,
disconnect and remove the old circuit board, taking
note of the locations of the connectors. While not
necessary, you may find it easier to remove the air
lines and the cable carrier as well.
•
Replace the old draw bar board with the new one.
It is easiest to replace the solenoid leads (red and
black wire) before re-mounting the circuit board. The
solenoid leads go to the opposite side of board from
other connectors. This is the only connector on that
side (2 pin nylon).
Connect the black VFD interconnect RJ11 cable (with the
spade terminal ends) to the DB1 connector on the power
draw bar control board, and the ATC communication RJ11
cable to the DB3 connector as shown in the following
figure.
