SETUP
6. Connect the common wire (black) to 1TB-11 (#4).
7. Connect the signal wire (clear) to 1TB-12 (#67).
Note: If the upper limit switch signal comes from an interface on the cutting machine, exactly the same
wiring (using twisted shielded pair) must be provided from the limit switch. This shield must be
electrically isolated from other shields in other cables. A separate cable is recommended to
avoid ground – loop problems.
Connect the MAX200 Machines Together with Machine Hold Cables
To connect MAX200 machines with the IHS option together with hold interconnecting cables:
1. Pass the hold interconnection cable through the feed-through at the rear of the MAX200. See Figure 3-18 for
the cable layout, cable part numbers and lengths, socket pin configurations and wire colors and signal names.
2. Connect lead 87 (red) to TB3-87 (+12 VDC), lead 86 (black) to TB3-86 (neutral) and shield lead to shield
terminal. See Figure 3-15.
3. Repeat Steps 1 and 2 to connect the hold cable at the other MAX200s.
