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. There is
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 10mm
²
to System Ground to have a sufficient ground
connection. Use STAR type grounding. Interface cable shield should be connected at
system side.
