If all the electrical connections has been done correctly, when power on the controller, the
monitor of the controller will go to the main interface. If there are no error happened, that means
the automatic distance controller work well.
But if the monitor indicate that connection failed because of the cable fault or other
reasons，”connection failed” will be popped up. User should check the cable and the sensor
devices.
1.3 Control functions
2.2.1 Main interface introduction
◆“tracing on/off”：Enable or disable the tracing function. If it is tracing on, the color of
the button will changed into green, which means the controller is under the tracing
status. If the height of work sheet changes, the laser head will tracing the movement of
the work sheet and always keep the distance to be a constant value. If it is tracing off,
the tracing function is disabled. If the height of the work piece changes, the laser head
has no response to that during the motion of the cutting system.
◆“fast/slow”：is used to switch the manual speed to faster or slow.。
◆“menu”：there are children menus in the menu to set some functions.
◆“reset”： To reset the distance controller. Before running reset function, be sure that
the upper limit has been installed correctly.
NOTICE: There is danger during the reset operation because of the mechanical motion.
So all the section should be checked before that and try to avoid of human harm.
◆“±0.1”：modify the distance between the nozzle and the work sheet. Press one time,
0.1mm will increase or decrease 。
◆“move up、move down”： to control the laser head to move up or move down. If the
button is pressed, the laser head will be always moving until the button is released.
◆“alarm info”： Press the button; user will go to the alarm information records interface.
User can check the alarm information that happened recently. The maximum number of

small, the crash alarm will usually triggered because of the
metal dross during cutting. If the value is too big, this will
decrease the responsibility of the crash alarm protection.
Gas delay

If the limit protection is enabled, when the limit is triggered,
the motion protection will take affect such as rising the laser
head and stop motion.
2.2.3 Parameter management
Parameters management is used to save and restore the parameters of the distance controller.
Not everybody can operate this function. There are passwords for user to manage this function.
When user has configured all the parameters correctly, then these parameters can be set to be
default. So if the parameters have been changed, user can restore the right parameters from the
default. We suggest that user must save the correct parameters to be default when all the
parameters have been tuned correctly.
2.2.4 Alarm information
On the main menu, press “ALM INFO”to go to “ALM INFO”interface.
User can check the alarm information. The information include of the alarm time and alarm
source. The maximum records are 9 records that is saved. Press the “clear”, all the information is
cleared. User still can press “page up”or “page down”to check the information.

LFS-PM-T43 operating manual 7
2.2.5 Calibration
In the main menu, press “FUNCTION”to go to “CALIBRATION”interface.
Calibration is very important for a correct application of the distance controller. If the laser
head has stand by for a very long time or the environment has changed a lot, a calibration should
be done. If user has change or replace some parts of the capacitor, the calibration must be done
again.
Before calibration, slowly moving the laser head to close to metal work piece and let the laser
head to be standby status. Make sure that the metal sheet has been connected to the EARTH well
and the machine also connects to the EARTH well. Then we can start a calibration. If the metal
sheet is not connected to the earth well, the calibration may be failed. If the laser head is always
moving down to touch the metal sheet and never stop, user should check the metal sheet conduct
with the machine well or not. If the conduction is ok, then check the electrical connection and the
capacitor sensor is good or not.
The normal calibration is just as the following:
⚫Laser head move down toward the metal sheet
⚫Touch the metal sheet and stop for while
⚫Then rise up to reach a position
⚫Then move down slowly
⚫Touch the metal sheet again then rise up to standby position
When the calibration is finished, a calibration curve will drew on the screen. The detection
scale is also displayed. The curve indicates the response of the capacitor when the distance is

LFS-PM-T43 operating manual 8
changed. If the curve is smooth and the value is in the desired scale, that means the calibration is
successful. User can press “OK”to save the calibration data. If the calibration is not smooth and
there are noises on it, that means the calibration is failed. User can press “CANCEL”to ignore the
result. User should not save the calibration data. User should check the reason that has caused this
situation and do the calibration again and again until the curve is smooth.
Because the capacitor is a sensitive to temperature and humidity of the environment, user
should wait 3~5 minutes when power on to let the sensor and amplifier to reach a stable
temperature.
2.2.6 Auxiliary gas test
In the main menu, press “FUNCTION”to go to the “AUXI GAS”interface.
This function is used to test the auxiliary gas is good or not. Auxiliary gas testing include of 3
channels auxiliary gas testing.
Testing steps：example for test the auxiliary gas with high pressure，press ”HP gas”，then the
auxiliary gas channel is turned on. Release the button, then turn of the channel.
Notice ：Before testing the auxiliary gas, make sure the control system is in the standby
status. Or the testing can not be done.
