ADJUSTMENT:
1. Set “Height Control Knob” to middle
position. 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
OUTPUT 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
OUTPUT led is ON.
5. Disconnect BNC connector and verify
that ERROR1 LED is ON. Short 0V
supply to Sensor Ring with some wire
and observe that the ERROR2 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. Set adjustment pot to middle position.
2. In Home position of your Z axis DOWN led is 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 OUTPUT 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 OUTPUT led is ON. If not, readjust the coil.
4. If you 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
Important:
Do not turn fully CW or CCW and do not apply force to the CORE of the
internal coil. The CORE is easily broken.
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.
