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.
