SETUP
Connect to the Inductor Sensor Assembly
1. At the Torch Mounting Subassembly, connect the two (2) 40-foot IHS/Sensor cables to the two (2) 3-pin
connectors of the inductor probe assemblies (see Figure 3-15). Also see Figure 3-17 for the cable layout, cable
part numbers and lengths, socket pin configurations and wire colors and signal names.
2. Route the two (2) IHS/Senor cables to the IHS Control Module and connect to 4- pin receptacles
(see Figure 3-15).
Connect the Air Hose Assembly
1. At the Torch Mounting Subassembly, connect the air hose (# 024144) to the air cylinder adapter (# 027024)
(see Figure 3-15 ).
2. Route the air hose to the air outlet fittng (same side as the inductor sensor connections) on the IHS Control
Module.
Install the Upper Limit Switch and Cable (customer-supplied)
Install the upper limit switch on to the torch lifter. This switch is to be normally closed. It opens when the torch is
fully retracted. The required operating specifications are +12 VDC @ 1.2 mA. Gold-type contacts are preferred.
Connect the Upper Limit Switch to the IHS Control Module
Caution: To avoid electromagnetic interference problems caused by the close proximity of
the upper limit switch cable to the torch lead set, follow the cable installation
procedure.
1. Use a shielded, twisted pair of 22-24 gauge wire (stranded). Belden # 8761 is recommended.
2. At the upper limit switch, connect the common wire (black) and signal wire (clear) to the upper limit switch.
Cut the shield drain wire (uninsulated). Wrap the cut end with tape to ensure the cut end does not contact the
cutting machine frame (see Figure 3-15).
3. At the IHS Control Module, loosen the two (2) latches and open the front cover.
4. Route the cable in through the strain relief in order to connect the cable wires to 1TB.
5. Connect the shield drain wire (uninsulated) to 1TB-10 (#S). Be sure the drain wire does not contact the IHS
Control Module case. Note that the cable shield is now electrically connected to the MAX200 frame.
