3.2.2 Points linking piece function introduced
Points linking piece is after the plasma cutting torch arcing voltage according
to certain proportion is reduced, and according to the isolation of converted to
reflect the cutting nozzle and the function modules of the low voltage signal of
cutting plate height, is the height measurement and control of plasma cutting
indispensable accessories. Points linking piece can choose according to need
to install location, it is recommended that the installation within the plasma
power supply and the platen each interface description as shown in figure
3-2-5.

Clockwise pressure ratio increases the score (about 110: 1), the output voltage
become low, 100V input voltage, for example the partial pressure than to
maximum (110:1), the display of 45V block.
Counterclockwise points pressure ratio (minimum about 40:1), namely the high
output voltage and 100V input voltage, for example the partial pressure than to
a minimum (bound), the block is shown as 125V.
Partial pressure ratio adjustment potentiometer factory of 50:1, try not to

4. Parameters shows
There are three commonly used parameters and two debugging: 1. Set
voltage. 2. Starting arc delay. 3. Locate latency. These parameters can be
directly set corresponding knob on the panel to adjust adjustment.
1. Set voltage, this can at any time by the knob to adjust the "height", on the
left side of the digital tube display voltage value set, the unit: (V), clockwise
to increase the voltage, counterclockwise to reduce voltage. Automatic
Type

cutting according to the parameters of the controller adjust the distance
between the nozzle and the steel plate, make the arc voltage is always
closer to set the voltage. This parameter can be directly as a set of highly.
Specific set number according to the selected power supply manufacturers
provide technical parameter settings.
2. Start arc latency, punch time should be used according to the actual
perforated time settings, different thickness of steel plate and different
current when the time is also different. Clockwise to lengthen the period of
rev arc, counterclockwise to reduce arcing time.
3. Positioning delay, initial positioning time is the initial positioning, cut down
to touch with steel plate, after ascending to the time required for setting
height. The time required for different lifting mechanism to promote a
certain distance is different too.It should be set according to the actual
situation. Clockwise rotation for higher position height, counterclockwise to
reduce positioning height.
4. The speed parameters, the parameters for debugging, available to open
less than 3mm of a word or a cross screwdriver adjustment, to reduce the
clockwise and counterclockwise to increase. Adjust the parameters affect
the motor rotation speed and the response time of the whole. The knob
position as shown in figure 4-1.
5. Set position limit switch logic, S1 jumper cap inserted between 1 and 2 for
the low effective, suitable for use normally closed proximity switch. Inserted
between 2 and 3 for the high effective suitable for open still proximity switch.
The factory default for the low effective. Jumper on the panel position as
shown in figure 4-2.
6. With or without positioning function setting, S2 jumper cap inserted in
between 1 and 2 for positioning function. Inserted between 2 and 3 for no
positioning function. Jumper on the panel position as shown in figure 4-2.

5. Tutorials
Noun explanation: control signal effectively, refers to the input signal with the
corresponding public end (24V) through. Disconnect as invalid.
Raise the controller after power-on self-test, self-check project has panels and
the host software version number display, and host communications, electrical
circuit is normal. If the introspection through digital tube display not normal or
up and down limit indicator lamp lights up at the same time and cannot perform
any action. Self-checking by into working state and working state is divided
into two kinds: manual and automatic state.
5.1 Manual operation
Manual rising signals (UP): When is effective, cutting torch rising.
Manual down signal (DOW): When is effective, torch down.
Manually drop signal (DOW): Long time effectively executed when positioning
movements.
Start arc signal (ARC): If is effective, the positioning action first, and then
control and arc plasma power.

5.2 Automatic operation
Reach to automatically adjustable requirement:
1. Start arc (ARC) signal effectively.
2. Automatic (AUTO) signal effectively.
3. Appropriate plasma cutting voltage ((set voltage-50) ~ (set voltage + 60)).
Initial positioning: the block after receives the start arc (ARC) block driving
down hoisting mechanism, Zero point (Zero) signal is valid, said cutting device
has met the steel plate, the tones to rise block driven lifting gear, rise time for
"IHS time", "IHS time" to finish the initial alignment is complete.
Start arc output: after the completion of the initial positioning output and arc
signal to the plasma power, such as waiting for a time after acquisition of arc
voltage.
Start arc successful feedback: the arc voltage within a certain amount of time
keeping within the normal range is rev arc (perforated) has been successful,
the block signal success (0-OK) to the numerical control system.
Automatic tracking: in success (0-OK) signal was given and the numerical
control system that start arc can be cut to walk successfully, at this time as
long as the numerical control to the block signal automatic (AUTO) to the block,
the block will enter into the state of automatic tracking.

6. NC system associated with adjustable block M instructions
6.1 M function of NC system to control the output port directly
M12 / M13 start arc switch, M12 (open), M13 (close)
M14 / M15 cutting torch rises switch, M14 (open), M15 (close)
M16 / M17 cutting torch switch, M16 (open), M17 (close)
M38 / M39 adjustable block automatic/manual mode switch M38 (automatic)
M39 (manual)
6.2 M function fixed cycle
M07 perforation fixed cycle
Plasma cutting operation sequence is as follows:
M07:
1. The cutting torch fell (cutting torch down latency, see M71).
2. Open the arc switch.
3. If the parameter setting is in the arc pressure detection from 0 (no), there is
no any arc pressure, delayed perforation delay (seconds).
4. If the parameter is set in the arc pressure detection choose 1 (testing) arc
pressure measurement, waiting for the starting arc "success".
5. Delay "higher automatic delay".
6. Open the block (M38), began to run after the program.
M08 close cut fixed circulating
Plasma cutting operation sequence is as follows:
M08
1. Shut down the block (M39).
2. Close the arc pressure switch.
3. The cutting torch rises (M70).
