Plasma Interface Upgrade

128408 KIT CONTENTS

PURPOSE

To replace the plasma interface assembly or the interface PCB, the command THC must be upgraded with a
new plasma interface assembly. The upgrade requirements include installing the new plasma interface
assembly, installing 2 new control module microprocessors and recalibration of the THC system.

MAX200, HT2000 and HT2000LHF Initial Height Sensing (IHS)

Initial height sensing (IHS) for the MAX200, HT2000 and HT2000LHF systems can now be accomplished
using the new Command THC torch Ohmic Contact Sensing function. To take advantage of this
enhancement, you will need a new torch retaining cap and a THC ohmic contact wire. See the applicable
setup section of the instruction manual (802780) included with this kit for parts and installation requirements.

INSTRUCTIONS

ELECTRIC SHOCK CAN KILL

• Turn off the power and remove the input power plug from its receptacle before
removing any access cover. If the power supply is directly connected to a line
disconnect box, switch the line disconnect to OFF (O). In the U.S., use a "lock-out
/ tag-out" procedure until the service or maintenance work is complete. In other
countries, follow appropriate national or local safety procedures.

• Do not touch live electrical parts! If power is required for servicing, use extreme
caution when working near live electrical circuits. Dangerous voltages exist inside
the THC control module that can cause serious injury or death.

STATIC ELECTRICITY CAN DAMAGE CIRCUIT BOARDS

• Put on a grounded wrist strap BEFORE handling PC boards.
