This "User's Guide" refers to Vers TSm v7 models and below.
Purpose.
The Vers TSm sensor is used to determine tool height and diameter. CNC milling machine generates coordinates when the tool touchs the VersTSm measurement pad and uses them to calculate the height and diameter of the tool. The device can be used with various CNC systems: LinuxCNC, Mach3, embedded systems on industrial machines, etc.

Installation.
Placement Vesr TSm is recommended to be chosen so that the entire surface of the ceramic platform of the device is in the working area of the machine, with an indent from the boundaries = the maximum diameter of the tool being measured + 2mm.
The device is fixed to the machine body with three M3 screws. Three threaded holes are prefabricated in the machine body:
Adjustment.
Before starting the measurement, it is necessary to adjust the device. As a result of the adjustment, the surface of the measuring platform should become parallel to the XY plane.
The indicator should be sensitive to a weak effect of 0.3-0.5N (for example, most lever indicators have this property).
For adjustment, three points are selected at the measuring pad (shown with red crosses) approximately at the edge of the site in the direction of the adjustment holes. The indicator is set in the spindle (you will need to moving the spindle in XY coordinates), the stylus of the indicator is located to measure the deviations in height. The results of the indicator must have to the same values in these three selected points. For adjustment, a 2mm hex key is used from the kit, both screwing in and loosening of the adjustment screws located inside the holes, closed with elastic bands. The key is recommended to hold for a short lever, so as not to develop excessive force when screwing.
Connection.
Only for versions v.6.3 and below. Be careful!
1. Reversing the polarity when power will damage the sensor.
2. Vers TSm is an NPN-NC sensor, i.e. output normally closed to ground. Connection to controllers with PNP inputs, i.e. designed for short-circuited to power PNP sensors , it is possible only with the help of special npn-to-pnp converter, otherwise, both the sensor and the controller may be damaged.
Starting from v.7.1, the sensors are equipped with NPN and PNP outputs, polarity reversal protection, protection against short circuits of the output to power and ground.
NPN or PNP output is selected by the customer during the checkout process.
The color of the wires inside the cable corresponds to the colors of the connections in the scheme.
Using.
There is software ProbeScreen and Auto Tool Measurement in free access for convenient work with probe in the LinuxCNC(ver.2.6 and higher),
Probe Wizard - in the Mach3 system.
