1Characteristics
BK MIKRO LIN.B is a tool monitoring system
customized for longitudinal scanning applications.
The complete BK MIKRO LIN.B system comprises
•a control unit,
•a sensor (scanner),
•a connection cable.
BK MIKRO LIN.B is based on existing design concepts for tool, object and free space monitoring.
These system monitors geometries, which require longitudinal scanning, especially in cases where
rotary scanning is inappropriate or impossible, for example cavities, bore holes, limited space
arrangements or critical coolant pressure.
The two control units "Multi" and "Single" have different features of monitoring:
•Tool monitoring
Monitoring of the scanning position whose precise location has been previously entered by
"Teach-in", e.g. to carry out a tool check before each working cycle (tool monitoring), especially
for "Multi": 8 scanning positions can be coded.
•Object monitoring, free space monitoring
Monitoring a scanning range freely selectable via two adjusting switches, e.g. to check cavities
with varying depth (object monitoring), or to check bore holes (free space monitoring), only for
"Multi".
Two types of scanners are available for each control unit.
TK50-LIN.B : Scanner with maximum stroke of 50 mm.
TK100-LIN.B : Scanner with maximum stroke of 100 mm.
Principle of operation
The wand of the scanner scans tools, objects or critical process spaces free of potential,
in line with machine cycles.
A control unit equipped with a micro-computer triggers the movement of the wand upon an external
signal and passes the scanning result on to the machine control via relay contacts.
The galvanically isolated inputs and outputs guarantee a high degree of operational safety and
protection against interferences.
Further features
•Variants for the tip of the wand (also project-specific)
•Two steps for scanning intensity
•Output relay contacts selectable as N.C. or N.O.
•Various ranges of tolerance for "O.K." message
•Indication of the scanning result by two LEDs for "O.K." and "K.O." at the control unit
•Detection of cable breaks

2System Components
2.1 Control unit
The control unit is available in three models preconfigured for different supply voltages.
The relevant version will be marked on the rating plate: 24 VDC, 120 VAC, 230 VAC.
On its front panel, the control unit is fitted with plug-in screw terminals to connect all machine
inputs and outputs, supply voltage, and the scanner.
•The screw terminals have been arranged on two plug-in terminal blocks. These blocks
are keyed so that they cannot be accidentally plugged into the wrong socket.
•When in operation, plastic caps cover the screws in the front. Wires to be connected are routed
from the top or bottom of the unit.
The scanner will be connected via a 6-wire cable to the scanner socket of the control unit.
Fig. 2-1:Control unit –Front view with plug-in connections
Note:
These plugs may only be inserted or removed
when the power supply has been disconnected.

Relay outputs
K.O. These two terminals are used to indicate a fault message (K.O.).
O.K. These two terminals are used to indicate a no fault message,
i.e. a good cycle (O.K.).
The terminals have been designed as dry relay contacts. By switch selection, they may be
configured as either normally open or normally closed.
The contacts have been designed for 250 VAC and, by additional internal circuits, protected
against inductive switch-off peaks of up to 19 W (2 ms).
Note:
Relay as normally closed contact: active =open
inactive =closed
Relay as normally open contact: active =closed
inactive =open
When there is no power to the unit, the contacts always will be open.
Even when using relay as normally closed, they are open
(like the active status) when the power supply is not connected.
2.1.3 Light-emitting diodes

2.2 Scanner
The scanner housing is cylindrical and smooth, thus permitting easy installation (e.g. by using a
mounting bracket). The scanner is designed for easy access for servicing and changing the wand's
tip. Aligning the scanner is easy and requires no additional instruments or aids.
After a supply voltage has been applied, the scanner travels from the momentary position to the
internal backstop, moves into its stop position and will be held there by applying a low voltage.
Using the scanners with a different control unit than BK MIKRO LIN.Bmay damage the scanner
and control unit.
Note:
•Due to its small diameter, a wand is easily overlooked.
•Your wand is a wearing part! Each contact with a rotating object will cause
corresponding wear on the wand. This may even lead to the metal wand
breaking.
Due to the injury hazard this causes, users should exercise particular caution
within any BK MIKRO moving area.

2.2.3 Scanning Wand
Stop position
Stop position = Zero position of the wand
Stop position ≠ Internal backstop !
Fig.2-11:Stop position of the wand
Note:
Do not push the wand back to its internal backstop (the real limit position)
by hand.
This damages the gear !
Initial position
The tip of the wand is to be positioned at random between the object to be monitored and the
internal backstop of the wand.
After supply voltage has been applied, and at the end of "Teach-in" or "Start" the wand will move
into its stop position in any case.
Scanning range
Any scanning range between stop position and maximum stroke can be used.
Exchange the scanning tip
The tip can easily be removed from the wand (thread M3x6) and exchanged by a project-specific
variant.
