Electronics
The ThreadChecker electronics has one switch and two LEDs visible in the enclosure to
provide various setup and status functions. The power led indicates that power is
applied and everything is functional if it is green. Red or flashing red on the power LED
indicates a problem. The thread or status LED indicates the presence or absence of a
thread or teach status (see application information).
The ThreadChecker electronics and sensors utilize SMA type coaxial connectors: female
on the electronics, and male on the sensor cable. Four probe configurations for
detecting internal threads are currently available from 2mm to 10mm, and two probe
configurations for detecting external threads are available, more configurations are
created regularly (check with Kaman sales for current configurations). The sensor must
be attached snugly (finger tight) to the electronics assembly for the unit to function
properly.

Adjustment and Calibration
The ThreadChecker requires calibration to the users configuration before use.
NOTE: solid red on the power LED means that it does not recognize the sensor or
the sensor is disconnected. If the sensor is connected and this condition persists
after a teach then the electronics does not recognize the sensor and it may be faulty.

The switched output can be adjusted using the teach modes. See application
information for more details.

Switched Output Operation
The ThreadChecker’s switched output is a simple on / off switch. The switch can be
adjusted to trip anywhere along the sensor range using application teach modes.

Cleaning
The ThreadChecker is designed to have limited operation while immersed in liquids.
Some solvents may damage electronics module, sensor, or power I/O cable. Clean the
unit with a damp cloth.

EMI Performance
The ThreadChecker conforms with the applicable standards of Council Directive for
Generic for Light Industrial and Commercial Use. Under some EMI environments, at
specific frequencies, the ThreadChecker unit may experience a change in output
voltage. In general, when exposed to those environments covered by the EMC directive,
the user can expect less than 5% deviation of output. Contact Kaman for specific data
or for recommended solutions if you experience problems with the ThreadChecker.
