Hypertherm PAC500 Product Configuration - Manual (Page 27)

1-22 PAC-500
11d THC-1/Remote Voltage-Current Control (RVC) with Fluidic IHS
The THC-1/RVC system has the same benefits and components as the standard THC-1
(see 11b) with the additional feature of arc voltage and arc current control from a small
control station that can be located remotely from the THC-1 control module. A manual
transmitter interfacing the RVC control station and power supply completes this system.
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 module should be located as near to the control console as
possible. The hose from the IHS module to the control console is 2-1/2 feet (.76 m) long
Order the system.
