Safety notice

 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.
 Packing pieces must be installed in accordance with the provisions and
requirements of step.
 GND must follow THC instruction.

Installation note

 THC first check on electrical safety : Before 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)
 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 streel 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 being orderly set up , 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 can not be turned on,
we need to check whether the parameters can be set orderly.
 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.
 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.
 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】.
 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.
 Demand that torch retaining cap used for IHS wiring: After the cable of
plasma anode must be received a workpiece, the action that detect the torch
retaining cap collision and the initial positioning can work.
 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.
 Voltage divide board and voltage divide ratio: The ratio in THC is 100:1. And
vi

 It can suit external working conditions by changing parameter, so we need not
change hardware within equipment.
 It can change the electrical level of input signal which is useful. The input
signal acquiesce in low electrical level is useful. The high electrical level is
useful when we change it.
 Input and output is insulated by optocoupler, it is useful to protect equipment
from damage when voltage is bigger and electromagnetism pulse is disturbed.
 The arc start relay and the arc start prosperity relay is omron power relay, so it
is reliable when it work.
 It can observe the electrical level in work process.
 The different work process is mutual seal, it can avoid operate fault.
 When THC have a delay of boring a hole, it can use function which it can

marching after collision.
 When auto height control is proceeding, it can use function which arc voltage
can be adjusted by machine auto control
 After torch have accomplished, THC can automatic promote torch height, 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.
 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

2
 F1620 型便携式弧压调高器使用说明书

can promote the touch height which down initially(height can change by the panel
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
When we test collision by torch retaining cap, if torch retaining cap connect
with workpiece, 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 workpiece 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.
 Dual speed of IHS
After down initially, torch can descend 6 second by using fastest speed(the time
can change by menu), then it descend by using lowest speed(the lowest speed= the
fastest/4) until torch collide workpiece. Two speed down can promote work
efficiency, descend in appropriate height, reduce collision impact, 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
complish 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 yellow nixie tube
above equipment is used for display arc voltage setting value, the red nixie tube
3
 F1620 型便携式弧压调高器使用说明书

under equipment is used for display actual value of arc voltage. It is conveniency for
user to monitor arc voltage value in incising.
8） Menu Operation
When torch is not working, it can change parameter by panel button. It can
flexible change speed , working way and so on.
9） Spin button operation
The panel have three spin button, it can change arc voltage, down height
initially and delay for piercing.
10） High and low level control
Input switch can choose that low(or high) level is useful, it can suit
complicated applied environment. We choose that low level is useful before
equipment leave factory. Also it can change 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 workpiece, THC can send rise signal , it can avoid torch collide
workpiece continually and damage workpiece. 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 can not 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 setted(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 workpiece 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 named dynamic pierce function similarly. When piercing is working,
4
 F1620 型便携式弧压调高器使用说明书

torch need promote a height, it can avoid dress get into torch head. If dynamic
pierce lifting times that we set is 0, torch can not 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.

lighted during IHS test. If IHS test finish, the light will go out.

2.2 operation panel of explaining

1.Nixie tube function of displaying： Arc voltage value is displayed by two nixe
tube in our operation panel. During torch don not work and menu operation do not use,
it can display arc voltage 、IHS 、pierce delay value and so on. The yellow 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. Arc voltage setting value
can be change by turning the button named【弧压设置】，and the value that display in
yellow nixe tube can change. The red nixe tube display 0 when torch is not working.
The value that display in red nixe tube is actual arc voltage value during torch work.
2.2. Parameter spin button of setting：
There have three spin button of spin encoding in panel.
The spin button named“弧压设置”：When menu operation do not use, arc voltage
value can change by turning this spin button. If it turn clockwise, arc voltage value
will increase. If it turn anticlockwise, arc voltage value will decrease. Arc voltage
setting value is displayed in yellow nixe tube. When we change arc voltage setting
value, it should on the basis of workpiece thickness and torch speed, it also need use
parameter which offer by plasma power source. Torch height depend on Arc voltage
value when torch is working.
During torch is working, arc voltage setting value also can change by spin button,
and it can adjust torch height. This operation suit to adjust slightly torch height when
torch is working.
The spin button named“穿孔延时” ：When menu operation do not use, turning
the button can change the value of piercing delay time. If it turn clockwise, the value
of piercing delay time will increase. If it turn anticlockwise, the value of piercing
delay time will decrease. When the spin button is turned, the yellow nixie tube

8
 F1620 型便携式弧压调高器使用说明书

display“Dly”, the red nixie tube display piercing delay time, the unit is second.
When THC use the piercing delay time which user set, it can send arc OK signal
to CNC after piercing delay is finishing and arc voltage by sampling is effective.
Some CNC have piercing delay time, but this delay is calculated when CNC receive
arc OK signal. The authentic piercing delay time is the sum of piercing delay time of
THC and piercing delay time of CNC. If user do not want to use the piercing delay
time of THC, user can set it as zero.
The spin button named“定位高度”：When menu operation do not use, turning the
button can change height of IHS. If it turn clockwise, the height of IHS will increase.
If it turn anticlockwise, the height of IHS will decrease. When the spin button is
turned, the yellow nixie tube display“IHS”, the red nixie tube display the height of
IHS. The height of IHS set by delay, the unit is second.
When menu operation do not use, two nixie tube is display arc voltage setting
value. If user turn the spin button named “穿孔延时”or the spin button named“定位
高度”, it will display corresponding character. If the spin button is not turned for a
long time, the nixie tube will display arc voltage setting value.
3. Working condition indicator：
The panel have 8 LED light：
 电机上升 indicator：Turn on when torch lift up.
 自动调高 indicator：On means THC is on auto height control mode. If It
satisfy four conditions, the indicator will turn on：
1）The indicator named“自动/手动”is turned on.
2）CNC Auto height control enables.
3）THC have tested arc voltage.
4）The practical arc voltage do not exceed value added
between setting arc voltage value and arc voltage value of protecting(in genal, the
value is 30V).
 穿孔完成 indicator：The indicator is lighted, it means system have detected
the effective arc voltage value and piercing have competed. (it is piercing
delay time of THC over, it is not contain the piercing delay time of CNC)
 起弧指示 indicator：Turn on when THC send arc start signal out. If IHS
completed, this indicator is lighted when THC send arc start signal. During
arc start test, the indicator is lighted.
 电机下降 indicator：Turn on when torch lift down.
 碰撞指示 indicator：Turn on when torch touch workpiece or proximity switch
effective.
 自动/手动 indicator：The indicator up the button named【自动/手动】is
indicated whether allowed auto height control. If the indicator is lighted,
THC will allow auto height control. If the indicator is extinguish, THC will
9
 F1620 型便携式弧压调高器使用说明书

not allow auto height control. The indicator is lighted after starting up. The
indicator condition will change when the button named【自动/手动】is pressed.
 定位测试 indicator：The indicator up the button named【定位测试】is lighted
during IHS test, it means IHS test is working. The indicator is extinguish
during other condition.

2.3 Menu operation explain

THC have concise menu, it can set some parameter and adopt to different work
condition. Menu operation use the button named【菜单】、【确认】、【+】、 【-】and so on.
It also use two nixie tube to display parameter, the yellow nixie tube display
parameter number and the red nixie tube display parameter value.
When user use it on the scene, parameter number and meaning can refer to
concise parameter grid up the chassis.
During torch do not work, when arc start and IHS test do not work, user press the
button named【菜单】can enter into the menu operation model. After it enter into the
menu model, the button named【定位测试】 、【起弧测试】is trashy. Only the button named
【▲】、
【▼】and the signal named THC_UP、THC_DN that CNC send is useful. If THC
enter into the menu model, it will not test and cut.
When THC enter into the menu model, it mean THC enter into first submenu
named “Pxx”（xx is parameter number），if the button named【菜单】is pressed again，
THC will enter into second submenu named“Hxx”. When the button named【菜单】is
pressed, THC can switch the next submenu. When it have switched the last submenu,
if the button named 【菜单】is pressed, it will exit the menu model. THC can test and
cut until it exit the menu model. So user need exit the menu model in time after
parameter have changed.
When THC switch submenu, the submenu is in a view model, it display first
parameter of submenu. For example, the first parameter of first submenu is named
“recover factory parameter”. The yellow LED display“P00”，the red LED display“ 1”.
When the submenu is in view model, pressing the button named【+】can switch the
next parameter in same submenu. For example, the yellow LED display“P01”, when
the button named【+】is pressed, it can display“P02”. The red LED display value of
P02. When the button named【+】is pressed again, it can display“P02”, by parity of
reasoning. Similarly, pressing the button named【-】can go back the last parameter
successively.
When the submenu is in view model, pressing the button named【确认】can enter
into the parameter modification model. Then the red LED start flicker, it means this
parameter is waiting for changing. Pressing the button named 【 + 】 / 【 - 】 can
increase/decrease parameter, the value which user change will display in the

10
 F1620 型便携式弧压调高器使用说明书

parameter. After parameter have changed, user can save it by pressing the button
named【确认】and cancel it by pressing the button named【菜单】.
If user save it by pressing the button named【确认】, the red LED will stop flicker
and display the value which user have change. If the parameter have changed and user
cancel by pressing the button named【菜单】, the red will stop flicker and display the
value which the parameter before it 显示的还是修改前的参数值。
THC have“Pxx”“Hxx”“Lxx” three submenu.With the addition of non-menu
model, it have four condition. When the button named【菜单】is pressed, THC can
switch in four condition circularly. Warning: During the non-menu model, if THC
is testing or auto height control is working, THC will not enter into the menu
model and change parameter. Similaryly, if THC have entered into menu model,
it will not start test and auto height control. After the parameter have changed,
user must be remember to exit menu model in time.
“Pxx”submenu contain 21 parameters, they are“P00”~“P20”and contain sundry
quantification parameter. The sundry parameter can change in this submenu.
“Hxx”submenu contain 9 parameters, they are“H01”~“H09”. It is used to check
input signal is high level or low level. The sundry parameter can not change in this
submenu. Warning : During torch start to work, pressing the button named【菜
单】can look up the level condition of input port.
“Lxx”submenu contain 9 parameters, they are“L01”~“L09”. It can be set the
input signal as high level effective or low level effective. The sundry parameter can
change in this submenu.

collision can happen several time then
make THC stop to work. When user
setting it as 0, if the collision happen is
checked by THC, it can send a
collision halt signal to CNC during
torch work.

proximity switch collision check is
allowed.
P14 1-50 1 50 P14 50 Brake speed adjust step and length.

P20 0-20 0.1 6 P20 6.0 Unit ： Second(S). The time of

speed IHS.

Parameter explain particularly:

1. P00：Recovering factory parameter. P00 can display 1. If user set it as 0 and
save this parameter, all kinds of parameter in our equipment will recover factory
parameter. After user exit the submenu, they can find that P00 display 1.
2. P01，P02，P03，P04：Setting manul lifting and auto lifting speed of torch. The
minimum speed is 0, the maximum speed is 50.
3. P05： The value of promoting arc voltage. During torch is cutting, if gun of
torch go through the crack of torch, arc voltage can rise immediately. If way of
protecting arc voltage is not used, gun of touch will descend by fast speed. In
serious condition，gun of torch and workpiece can collide by faster speed. After

13
 F1620 型便携式弧压调高器使用说明书

user set this parameter, when arc voltage exceed the value of setting, torch height
will not change. It is useful to protect torch. In genal ,we set it as 30V.
4. P06：The arc voltage precision of adjusting. For example, if user set the
parameter as 1V, it means when D-value between setting arc voltage and practical
arc voltage is under 1V, torch height will not be adjusted. If user set the parameter
as 3V means when D-value between setting arc voltage and practical arc voltage
is under 3V, torch height will not be adjusted.
5. P07：Sensitivity coefficient. When arc voltage is changing, more and more
bigger parameter can make torch adjust become more and more faster. But if
parameter is too big, torch is easy to quiver around the balance location. If
parameter is too small, torch can have slow follow speed. In genal, we set it as 6.
When user use it, it can be adjust on the basis of torch effect.
6. P08：The time of torch rise spear urgently. During torch do not work , when
torch collide the steel, THC can use fastest speed rise spear urgently in this time.
7. P09，P10：Setting the function of arc voltage auto adjust. During torch is
cutting, because of the arc voltage that user set is too low, or with service life of
plasma pierce is decreasing, arc voltage in plasma power source can rise. If arc
voltage value of setting is invariant, height will drop and it even can collide
pierce after auto height control. During torch is cutting, when collision have
happened, if user want to make torch promote some height and continue to cut,
this function will be used by user. According to this function, THC can increase
arc voltage value of setting automatically and increase torch height after collision
happen twice. It can avoid torch continue collide pierce. During torch is cutting,
when collision have happened, if user want to make torch promote some height
and continue to cut, this function will be forbidden by user.
8. P11：The time of allowing collision happen during torch work. During torch is
cutting, if user allow torch continue to cut after collision have happened, user can
set the time of allowing collision happen by changing this parameter. For example,
user set the parameter as1. Then during torch is cutting, when first collision
happen, THC can not send collision signal to CNC. But THC can make torch
promote a IHS height automatically. When collision happen again, THC can send
collision signal to CNC. After CNC receive this signal, torch stop to work. In
other example, user set the parameter as 3. After collision happen at the fourth
time, THC send collision signal to CNC and the input is TO CNC COLLISION.
9. P12：Switching motor contrary or plus direction of rotating. If user develope
direction of motor and the button of lifting/descending is different, they enable
this parameter will change direction of motor. For example, when user set P12 as
1, if the button of lifting is pressed, motor will descend. When user set P12 as 0,
if the button of lifting is pressed, motor will lift.
14
 F1620 型便携式弧压调高器使用说明书

10. P13：Enable the proximity switch collision test. When user set it as 1, THC can
use the proximity switch to test collision. When user set it as 0, THC can not use
the proximity switch to test collision. When user set it as 1, user need make
proximity switch put in THC and ensure that proximity switch is not breaking
away from. Otherwise, lifting motor can rise straight because of THC can not
receive the collision signal.
11. P14： Brake acceleration. This parameter can set deceleration time value when
motor stop to work. This parameter is bigger, deceleration can become faster, the
time of motor stop work can become shorter. The biggest parameter is 50.
12. P15：Reversion acceleration. Speed adjust step and length when motor turn
contrary. When motor speed is changing or motor turn 正 become turn contrary.
It can change speed value by change this parameter, the bigger parameter can
make reversal transition speed become more and more smaller. We set it as 100(it
is the biggest value), user can adjust this parameter on the basis of specific
condition when they used THC.
13. P16：Arc voltage delay time of setting. After arc start command is sended and
delaying in this time have finished, THC start sampled the arc voltage value. This
time can be used for avoiding to sample severe and waved arc voltage when arc
start start to work.
14. P17：Torch lifting time after starting up. When THC is starting up, the time of
promoting the lifting motor. It can avoid some condition that the distance between
torch and workpiece is nearer. If user do not pay attention to make equipment
start to work and move the torch, it will lead to happen collision. Lifting torch can
avoid this accident happen after starting up.
15. P18：The time of promoting the spear after torch have accomplished. After
torch have accomplished, torch can lift a height. When arc start test, if user
loosened the button named【起弧测试】, torch can lift in this time.
16. P19：Torch lifting time when arc start start to work. When piercing delay time
is not setted as 0, THC can used this parameter and send a commend of arc start.
Arc start is working, at the same time, torch is lifting in this time. Before piercing
have accomplished, torch can descend a height which it is the same with
promoting height. It can 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 can not promote when arc start
is working.
17. P20：The time of descending rapidly during the dual speed IHS. During the
dual speed IHS, at first, motor descend by fastest speed in this time. Then motor
descend by lowest speed until collision have happened(lowest speed= fastest
speed /4). If user set it as 0, motor will descend by fastest speed/4.

2.5 工作过程

带初始定位的切割过程
当数控系统连接的起弧信号是带初始定位的起弧操作（IHSAON）信号时，调高器首先
进行初始定位操作：割炬下降，直到发生碰撞，然后提升割炬到初始定位高度，调高器发出
起弧命令，控制起弧继电器闭合，等离子电源开始起弧，起弧成功后，经穿孔延时时间后，
调高器向数控系统发出起弧成功信号。数控系统开始切割，如果调高器处于自动允许状态，
且数控系统已发出自动调高信号，则调高器处于自动调高状态。切割过程中，若按动调高器
面板的【自动/手动】键使调高器退出自动允许状态，则暂停自动调高，割炬保持高度不变，
若再按【自动/手动】键使调高器恢复自动允许状态，则调高器继续自动调高。切割完成后，
数控系统关闭 IHSAON 信号，调高器自动控制割炬提升到设定的高度。

3.3 分压板接口

3.3.1 弧压接口

F1620 型便携式弧压调高器采用内置分压板，检测等离子弧压、保护帽碰撞信号。下图
为整体接线示意图：

图 3.11 分压板接口接线

27
 F1620 型便携式弧压调高器使用说明书

本调高器检测等离子弧压时，采用分压电路检测，将等离子输出的弧压经 100:1 分压后，

输入到调高器主机。如上图所示：
ELECTRODE 端子（PCB 板上丝印字 ELECTRODE）接等离子弧压的负极（阴极）
；
WORK 端子（PCB 板上丝印字 WORK）接等离子弧压的正极（阳极）；
SHIELD 端子（PCB 板上丝印字 SHIELD）接保护帽碰撞检测引线。

等离子电源的阳极接地，阴极接割炬的喷嘴，喷嘴上的电压为负电压。切割时，弧电压
的绝对值一般大于 100V，由于电压较高，且起弧时干扰较大，必需进行隔离分压才能用于
控制。本调高器分压板采用 100:1 的分压电路，可以测量的弧电压范围为 0V~660V。
注意：等离子电源弧压采样电缆需使用高压屏蔽电缆，且正负极不得接反。若弧压正
负极接反，则自动调高无效。等离子电源弧压线需从等离子电源输出端的接线桩引出，不
能从割炬和工件处引线，防止高频干扰。

3.3.2 保护帽碰撞检测电路接口

本调高器可采用两种定位方式进行初始定位：
一、 保护帽碰撞检测定位方式；
二、 接近开关定位方式。
对于保护帽碰撞检测定位方式，需用高压电缆将金属保护帽与分压板 SHIELD 端子连
接起来，如下图所示：

图 3.12 分压板保护帽碰撞检测接线示意图

28
 F1620 型便携式弧压调高器使用说明书

保护帽碰撞检测定位方式的工作原理：调高器收到数控系统发出的起弧信号后，割炬先
下降，直到保护帽接触到工件，一旦保护帽接触到工件，碰撞检测电路就会接通，调高器立
即收到碰撞信号，立即控制割炬上升，上升到设定的高度时定位完成，调高器即控制等离子
电源起弧。
实际使用过程中，需注意以下事项：
1） 接线时，高压导线从分压板上丝印为 SHILED 的端子起，穿过压线孔，再连接到
保护帽上，同时，可在高压导线靠近分压板的位置绕上一个磁环，并将高压导线在磁环上多
绕几圈，能有效防止等离子弧压的高频干扰。
2） 切割料架和工件与等离子电源阳极必需短路，并保证回路为低阻抗。通常接线都能
保证这一点，不需要特别处理，因为等离子电源阳极连到工件上时，已保证了回路短接。
3） 接地柱 PE 必须良好接地，接地导线截面面积＞4mm²。
4） 保护帽与工件接触时的接触电阻必需<20kΩ，否则保护帽碰撞检测回路会因阻抗
过大而无法动作。这一点对于生锈的钢板尤其需要注意，如果钢板生锈严重，在切割之前应
清扫钢板表面，将生锈层杂质去除。
5） 保护帽碰撞检测电路只需要一根碰撞检测信号线即可，回路利用了弧压采样的引
线，因此节省一根高压电缆。
注意：保护帽碰撞检测电路和接近开关检测电路可同时工作，两种方式任何一个检测
到碰撞信号均可完成定位。一般来说，保护帽定位信号会先触发，完成定位，但是某些时
候工件生锈氧化或有保护层绝缘的话，保护帽定位无效，若保护帽定位无法完成时，由接
近开关作为后备保护来完成定位。
保护帽定位只要接线正确，就一直起作用，而接近开关可根据参数选择是否使用，当参
数 P13 设为 1，则使用接近开关碰撞检测，此时需要将接近开关接上。当参数 P13 设为 0，
则不使用接近开关检测碰撞。
