1-24 PAC-500
11e THC-1/Remote Voltage-Current Control (RVC) with Inductive IHS
This variation of the THC-1/RVC is identical to the THC-1/RVC unit described on page
1-22 (11d) with the exception of the IHS system. Unlike the fluidic IHS, the inductive IHS
can be used for both above and underwater cutting applications. The inductive IHS
system requires a regulated air supply of 20 psi (1.4 bar) to operate the probe assembly
air cylinder. Two probes, two probe cables, an air cylinder and air cylinder hosing are
included in this package. The IHS module must be located within 40 feet (12 m) of the
torch. A torch mounting bracket is also included with the inductive IHS system. Do
not order a separate torch mounting bracket when ordering the inductive IHS
option.
Note that with this system, cables from the THC-1/RVC module to the IHS, cutting
machine controller, RVC control station, torch lifter, and star ground are not sup-
plied by Hypertherm. Use six-pair 22-gauge cable to connect the THC-1/RVC module
to the IHS, cutting machine controller, and RVC control station. Use five-conductor 18-
gauge cable to connect the THC-1/RVC to the torch lifter, and 18-gauge stranded copper
to connect the THC-1/RVC to star ground.
The cable from the IHS module to the control console is also not supplied. Use six-
pair 22-gauge cable for this connection.
Cabling is also not supplied connecting the transmitter to the RVC control station
and power supply. Use six-pair 22-gauge cable to connect the transmitter to the RVC
control station, and five-conductor 18-gauge cable to connect the transmitter to the
power supply. If power supplies are connected in parallel, use two cables between the
transmitter and the power supplies.
• Locate an area to mount the THC-1/RVC module (this should be in eye sight of the
operator), the RVC control station (this should be in easy reach of the operator), and
the transmitter. The IHS console must be located within 40 feet (12 m) of the torch. See
Specifications in Section 2 for weight and mounting requirements. Order the system.
