AGELKOM CAP04
Plasma and Oxy Fuel Torch height control
for sheet metal cutting machines
Height Sensor & Controller
Description:
SENSOR RING:
The metal sensor ring is connected to the CAP04 via a 90
cm long 75 ohms low capacitance coaxial cable. Thereis
a 2 size for Sensor Ring. The Plasma Ring ID is 34 mm
and OD is 47 mm. Sensing height of the ring should be
between 1,5 to 10 mm above the plate. The Fuel Ring ID
is 50 mm and OD is 69 mm . Sensing height of the oxy
ring should be between 7 to 35 mm above the plate The
ring must be insulated from all conductive parts of the
cutting torch.
ELECTRONICS:
The connection of supply and outputs to the CAP04 is via 8 core screened cable. Connector
can accept cable up to 6.5 mm OD diameter. The supply is nominal 24VDC and the
consumption current is less than 150mA.
Do not use same power supply with motors.
The all outputs are at normally low, 15V level during in active and drive up to 15mA.. These
outputs can directly drive LED or Opto Coupler. Due to current limiting, there is no need
voltage divider for 12 and 5 volts input range of your breakout board if inputs are opto
coupler isolated. Touch output can be adjusted internal trimpot as a minimum height. It
allows NULLING the height, if such feature required.
Voltage Control inputs are floating, with opto-coupler isolated. Inputs can be driven 0-10V
analogue output, however due to electrical noisy environment input has threshold level about
2-3V and range is 3-10V. It is also possible with external potentiometer (1K linear) as a
voltage divider for adjusting the height manually.
GROUNDING:
The diecast box must be grounded. Usually the sensor is bolted to the housing of torch lifter
and must be connected via thick wire 10mm² to System Ground to have a sufficient ground
connection. Use STAR type grounding. Interface cable shield should be connected at
system side.

ADJUSTMENT:
1. Apply 10V DC to Height Control
inputs. Adjust Height/Voltage
trimpot until 10V reading at
WHITE bead. Manually adjust the
torch lifter, so the ring is about 50
mm above the plate.
2. Disable the drive system (e.g.
electrically or mechanically
disconnect motor).
3. Activate CAP04 and monitor up
and down output. At this point
DOWN (GREEN) LED must be
on, if not internal coil adjustment
needed. (Refer Internal Coil
Adjustment Section).
4. Decrease the distance between
sensing ring and plate and verify
that UP (AMBER) LED is ON.
5. Disconnect BNC connector and
verify that CABLE (RED) LED is
ON.
6. Reconnect the drive system.
The correctly adjusted sensor should activate outputs within +/-0.05 mm at 1.5 mm above
the plate and up to +/-0.2 mm at 35 mm. with two sensor.
Internal Coil Adjustment: (if necessary)
1. Do not apply Height Control Voltage. This is for maximum height.
2. In Home position of your Z axis DOWN LED must be ON, if not:
Remove the front panel. Use plastic screw driver. Gently adjust of the internal coil of
CAP04 sensor and observe down output is activated in your HOME position (or
sufficiently high above the plate.) If DOWN LED is activated instead of UP readjust
the core of the coil.
3. Start slowly to decrease the distance between sensing ring and the plate to the cutting
height of say 3mm and verify that UP LED is ON. If not, readjust the coil.
4. If you need to change the cable between the unit to sensor ring, internal coil should be
re-adjusted. You can use 70 cm to 100 cm long sensor cable. The original cable length
is 90 cm and the type is RG59
Important:
Do not turn more than ½ tourCW or CCW and do not apply force to the CORE
of the internal coil. The CORE is easily broken. It is not a SESITIVITY
adjustment
Window Adjustment:
There is small amount of GAP (window) between UP and DOWN. Also GAP could
be adjusted with internal trimpot. Turning CW of trimpot makes gap wider. Increased
cutting height will result in a wider the GAP.

Touch (Down Limit) Adjustment:
After all adjustment was finished, you can start to adjust Down Limit potentiometer, adjust
this multiturn trimmer potentiometer (turn CCW) until TOUCH LED is OFF Afterwards,
close the sensor ring until it touches the plate or insert paper between sensor ring and plate
(cutting material). Turn CW until TOUCH LED is ON
APPLICATION:
During plasma cutting, sensor ring and plasma torch are in the same height. This will allow
to use TOUCH output as a collision detection means. If any fault occurs, the UP output
activate automatically.
During thick plate cutting, dross may touch the sensor ring and the torch head lifted. To
avoid this situation correct your cutting parameters for less dross.
CAP04-V can be used with voltage controlled Height Control System. The two systems are
OR’ed.

Height Control Input is floating

Adustment procedure as follows:
Apply these input 10VDC and adjust
trimmer potentiometer until to read at
WHITE BEAD about 10V. Reduce
control voltage about 3 volts and
measure 13.67V at same test point.
Between 0 to 3Volts, controlling is
disabled for the noise margin.
If no voltage applied, the same voltage
appear about 13.67V. This is the
Maximum Height Level
All adjustment made at factory. Please
do not change until it is necessary.

Connection Diagram:
Only one outputare shown. Cap04-V outputs are HIGH when activated. For UP, DOWN, TOUCH,
CABLE FAULT are at 15V and 15mA.
Check your input and configure for ACTIVE HIGH. Your inputs must be 0V level and Pull Up
resistor not used .
If your BREAKOUT BOARD has OPTO COUPLER inputs at 5V level, you can connect directly to
Cap04-V outputs
If your BREAKOUT BOARD has 5V digital level inputs please use voltage divider resistoras
shown below for each inputs.

Internal Coil Adjustment:
Mount CAP04 and Sensor Head with Sensor Ring to your machine.
Keep Sensor Ring to Working Plate distance at maximum (at least 10cm).
Important:
Do not turn more than ½ tour CW or CCW and do not apply force to the CORE of the internal
coil. The CORE is easily broken. Use plastic screw driver. It is not a SESITIVITY adjustment.
Smoothly close some metal plate (say 20cm x 20cm) to sensor ring and observe that voltage increase
(never decrease) come to closer.
