Safety notice
z This THC will switch in high electromagnetic,it can hurt me if we get to touch
with high electromagnetic . Do not touch shield cable and wire when power
supply is turning on.
z Packing pieces must be installed in accordance with the provisions and
requirements of step.
z GND must follow THC instruction.
Installation note
z THC first check on electrical safety : B efore THC first power,making all port of
wiring connected, then unplug motor cable, in other words, do not connect lifting
motor cable temporarily. Then powering on. (warning: Motor cable must be
unplug before powering on, otherwise, the reason why the lift motor has
been rising (declining) is that may be received collision signal , it can injury
lifting motor)
z Check whether the collision function is normal: After THC power on, check
whether the collision detection function is normal, by observing the collision
indicator light to determine whether the normal. Of the following circumstances:
1) If the collision indicator light is turning on, really need to check whether a
collision, for example, whether proximity switch is divorce, whether torch
retaining cap and steel is touching.
If we only use torch retaining cap to detect collisions, separated from the
protective cap and cutting steel. Because there is no contact with torch retaining
cap and steel, the meaning that the collision have not take place, the collision
indicator light should be take off.
If we only use proximity switch to detect collisions, parameter P13 should
be set to 1 , the meaning that allow the use of proximity switch detects a collision
signal. Under normal circumstances, the collision indicator light is turning on
when proximity switch is divorce; the collision indicator light is breaking down
when proximity switch is not divorce. If we use in scene, the collision indicator
light is breaking down when proximity switch is divorce, or the collision
indicator light is turning on when proximity switch is not divorce, it explain that
the description of the received signal and the normal, L09 need to set the value of
the inverse. After parameter is set correctly, proximity switch can accurately
reflect the situation of collision.
If we use proximity switch and torch retaining cap to detect collisions at
v
Portable Plasma Torch Height Controller Manual (F1620)
the same time, need to check respectively each set whether can accurately reflect
the situation of collision. If a certain way is failing, please use their method by
alone to troubleshoot and fix, until it can accurately reflect the situation of
collision.
2) If the collision indicator light is breaking off, please make some
collision conditions by man, check whether the collision indicator light can be
turned on. For example, when we use torch retaining cap to detect collisions, if
we make torch retaining cap and cutting steel short circuit by metal screwdriver,
the collision indicator light should be turned on. Or when we use proximity
switch, if we make torch connector crooked by hand, make proximity switch
take off, the THC collision indicator light should be turned on. If make visible
collision conditions by man and the collision indicator light cannot be turned on,
we need to check whether the parameters can be set orderly.
z Switching in lift motor safely: After the detection of THC collision have debug
and used normally, please remove all conditions which can made collision, at the
same time, THC collision indicator light should be broken off . Then turning off
power source of THC and connecting the lift motor cable.
z Check whether direction of lift move is true: After motor cable have been
linked, power-on ,when check whether the button named 【▲ 】 in THC faceplate
is pressed, observe whether the lift body is rising; when the button named【▼】 is
pressed, observe whether the lift body is declining. If the button named【▲】 is
pressed, the lift body is declining rather than rising, or if the button named【▼】is
pressed, the lift body is rising rather than declining, it means that direction of
motor rotation is not true. Please enabling the value of P12, or exchange two
cable of lifting motor. It is best that ensure the button【
▲ 】and【 ▼】 in THC
faceplate is consistent with direction of the lift body move.
z Check arc start and used for IHS(initial height sensing): check whether start
arc by pushing button of【text arc start】and check whether accomplish the initial
positioning by pushing button of 【 text used for IHS】.
z Putting in Arc voltage cable true: The wire of plasma arc voltage and cable of
checking collision must be access to the corresponding port true, otherwise, it can
lead to danger.
z Demand that torch retaining cap used for IHS wiring: After the cable of
plasma anode must be received a work piece, the action that detects the torch
retaining cap collision and the initial positioning can work.
z Using shielded cable wiring: In order to protect equipment work, please use
shielded cable in our equipment. You can connect shielding layer in Shielded
cable to THC side and use single point grounding.
z Voltage divide board and voltage divide ratio: The ratio in THC is 100:1. And

height which we promote can setting casually.
1.3 Function of equipment
1) Auto initial height sensing(IHS)
The way of IHS have the detection way of proximity switch and the detection
way of torch retaining cap collision.
¾ Proximity switch location detection
Our equipment use NPN model proximity switch (or PNP model proximity
switch), proximity switch is contacting when it do not work. When down testing or
arc down initially, if torch collide workpiece(or if collide workpiece make torch tilt),
proximity switch will break away from, then detection voltage can check this signal, it
can promote the touch height which down initially(height can change by the panel
2
Portable Plasma Torch Height Controller Manual (F1620)
spin button named “down height”). When proximity switch is breaking away from for
long time, torch can keep straight rise until it collide upper limit of motor.
Torch retaining cap collision detection
¾
When we test collision by torch retaining cap, if torch retaining cap connect
with work piece, detection voltage can be start and promote the touch height which
down initially(height can change by the panel spin button named “down height”).
After torch rise, torch retaining cap depart from work piece and collision signal reset
at once. If torch retaining cap signal is keeping for long time, torch can keep straight
rise until it collide upper limit of motor.
¾ Dual speed of IHS
After down initially, torch can descend 6 second at fastest speed (the time can
change by menu), then it descend at lowest speed (the lowest speed= the fastest/4)
until torch collide work piece. Two kinds of speed down can promote work
efficiency, descend in appropriate height, reduce collision impact, and extend serve
life of torch retaining cap.
2) Auto arc voltage height control
When it fit to start auto height control, if arc voltage do not exceed 30V which
we have been set up(parameter can change by menu), the THC will start auto height
control.
3) Auto torch promote after collision
When collision happen in a condition which torch and down is not working,
torch can automatic promote, the time named urgency collision rise spear time.
When down initially detection is working, or when collision happen within torching,
auto torch promote, the time named down height time.
4) Auto torch promote after torch is accomplished
After torch is accomplished, auto torch promote, height can change by setting
parameter.
5) Manual operation
Many functions can be manual operated on operation panel of THC, such as,
set auto/manual mode of THC, manually control torch up and down, IHS test arc start
test.......etc.
6) Auto operate
After numerical control system send arc start signal, THC can automatic
accomplish down initially—arc start—arc start feedback success, after CNC receive
signal which arc start feedback is successful, machine tool start to motion and incise.
7) The function of displaying and monitoring
THC display arc voltage value by using two nixie tube, the green nixie tube
above equipment is used for display arc voltage setting value, the red nixie tube
under equipment is used for display actual value of arc voltage. It is convenience for
3
Portable Plasma Torch Height Controller Manual (F1620)
user to monitor arc voltage value in incising.
8) Menu Operation
When torch is not working, parameters can be changed by panel button. Users
can flexibly change speed, working way and so on.
9) Spin button operation
The panel has three spin buttons; it can change arc voltage, initial height and
delay time for piercing.
10) High and low level control
Input switch can choose using low level or high level, it can suit complicated
applied environment. The default level is low. Also it can be changed by menu.
11) The function of avoiding collision
When torch is working, if the lower arc voltage setting value(or nozzle loss)
lead to torch collide work piece, THC can send rise signal , it can avoid torch collide
work piece continually and damage work piece. When collision happen in a
condition which torch is working, if collide have happened several times, we can
make numerical control stop work. Before equipment leave factory, if collision is
happening, CNC will make torch stop work. If user do not make collision input
signal connect with CNC, so when collision happen a condition which torch is
working, CNC cannot receive the collision signal, it make torch continue to work.
Whatever numerical control system whether have stopped torch, when collision
happened, THC can promote torch height automatically until down height initially.
When torch is not working, if torch collide steel plate, torch will automatic
promote a height named urgency collision rise spear height(in general, this height is
higher than down height, and this parameter can be change).
12) Intelligent arc voltage adjust
When intelligent arc voltage adjust is been use and torch is working, if torch
collide continuously steel plate twice, arc voltage can increase automatically a value
which we have set (this parameter can be change, it is 5V that we set), for example,
if arc voltage setting value is 110V, after torch collide continuously steel plate twice,
arc voltage setting value increase automatically 5V, arc voltage setting value is 115V
now, it can promote torch height to avoid collide work piece when torch is working.
13) Dynamic pierce function
During torch is working, if set-pierce have delay, torch can promote a height
when arc start work at the moment. Before delay time of piercing have
accomplished, torch can descend a height which it is the same with promoting
height. It can be named dynamic pierce function similarly. When piercing is
working, torch need promote a height, it can avoid dress get into torch head. If
dynamic pierce lifting times that we set is 0, torch cannot promote when arc start is
working.

14) Collision signal feedback
THC can make numerical control system receive collision feedback signal, it
can avoid that torch is working after collision have happened. THC make CNC
receive collision feedback signal after collision happened several times, it can keep
coherent torch.
