THC102MX Operation manual
Enviroment cannot contain any explosive gas.
It must be wired by professional wiring staff. Otherwise, it may cause electronic
shock.
Cut off the power supply before wiring. Otherwise, it may cause electronic shock.
Do not touch any control port, internal boards and their electronic componets
while the electricity is turned on. Otherwise, it may cause electronic shock.
Device information
The unit is a modern analogue - microprocessor plasma torch height
controller that operates by analyzing voltage changes in the plasma source due
to variations in height between the torch tip and the material being cut. The mi-
croprocessor makes determinations to raise or lower the torch based off of the
strength of the voltage signal being read. It is equipped with an easy to read LED
display and two user friendly keys making operation simple and does not require
any additional measuring instruments. The device has patented solutions made
with the highest quality components to ensure a safe, durable, and reliable long-
term operation.

ATTENTION:When connecting directly, use
the shortest possible cables for connecting
the plasma source with THC controller - it is
recommended the THC controller to be lo-
cated directly at the plasma source.
While being a universal THC, accepting full raw arc voltage for most
any plasma cutter on the market, an exciting new standard feature of
this unit is the addition of a 1:50 divider for an extremely fast, simple
installation on most major brands. There will most likely be a direct
connection for this on the outside of the plasma cutter’s unit. Please
refer to your plasma cutter owner’s manual.
An example of how to connect the THC controller’s measurement
input withthe output of the very popular Hypertherm Powermax45
®- The THC comesstandard equipped with a low voltage output of
1:50 divider. This ratio is the most commonly used division in most
major brands and there will most likely be a plug for this connection
on the outside of the cutter’s unit.

For 1:50 Ratio please set the
Jumper to 1:100 mode and use two
resistors 10K0.25Wlike the dia-
gram.

COM terminal is a common input terminal connected to the ARC, UP and DOWN
optocoupler contacts inside the device, according to the diagram located on the
cover.
Suggested route is to “GND” at driver/pc end. Do not jumper
this connection to the “7-35V” negative.
OK output is activated when plasma ignition is
detected and after the preset delay countdown. Route and configure for a software
input. Not required to operate.
UP output is activated when the measured voltage is lower than the voltage
setpoints, reduced by half the hysteresis voltage. Route and configure for a
software input.
DOWN output is activated when the measured voltage is higher than the voltage
setpoints, reduced by half the hysteresis voltage. Route and configure for a
software input.
Note: No output signals are activated in case when only the pilot arc is detected
and when the main arc is broken.
Signal outputs should be connected to the CNC system in accordance with the
documentation of the CNC electronic system controlling the machine. For this,
we use inputs of outermost connectors HOME or LIMIT - THC relay contacts
should be connected to the terminals the same way as limit switches connectors.
At the same time, the common COM terminal should be connected to the
CNC system to a common terminal for limit switches (it is usually a GND
terminal).
To reduce the possibility of the short-circuit entering the CNC system, the
connection should be made with a shielded cable - the shielding must be
connected to grounding on the CNC system side. Do not connect the shielding to
the THC controller side.
Start-up and operation:
The device is pre-configured at the factory and after the correct
connections are made, it immediately works properly with most plasma devices.
After switching power on, the THC controller’s display displays the Limit value at
left and three dashes at right side“- - - “ which means it present there is no input
voltage.
In this mode, by pressing the up/down keys, the threshold value can be modified
and thus set the height of the lens above the material.
To specify other parameters, press menu key,the HYS (hysteresis) parameter is
the first. By press the the menu key again, you can navigate through the menu
parameters. In this state, by pressing the up/down keys you can enter the value
of the current parameter. Once the value is set,wait a moment for automatically
store and exit the menu.

Summary
“HYS” (Hysteresis see image 15page 5) - The hystere-
sis voltage - a range in which the voltage is measured,
in which there are signals controlling UP/DOWN is
deactive.1-15V.Factory setting “1”
“dLy” (delay) - delay time of output OK when the sys-
tem detects the main (cutting) arc
1 - 15 seconds. factory setting: 1s
“CAL” (Calibration) - Due to material deviation the
recorded plasma voltage may need adjustment.
According to an external reference, such as the simple
voltmeter, you can modify the Plasma voltage reading.
-35V to +35V.Factory 0V
“tSt” (Test) - Simulation of the controller’s work - the
system simulates the appearance of “floating” Torch
within a countdown timer.By pressing any keys you
can exit from test mode or just wait a few seconds for
auto exit.
