2Characteristics
BK MIKRO 7 is a control system suitable for tool as well as for object and free space monitoring
applications.
The complete BK MIKRO 7 system is comprised of:
•a control unit,
•a sensor (scanner),
•a connection cable.
BK MIKRO 7 is based on existing design concepts for tool, object and free space monitoring and
can be used universally for different types of monitoring by the integration of multifarious functions:
•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.
•Object monitoring, free space monitoring
Monitoring a scanning range freely selectable via two adjusting switches,
e.g. to carry out tool checks for tools with varying diameters (object monitoring),
or for ejection checks (free space monitoring).
Two types of scanners are available for various demands.
From this two different monitoring systems result.
BK7SC: Scanner with mechanical backstop.
BK7RLSC: Scanner without mechanical backstop.
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
•Scanning in one direction or in both directions
•Scanning in clockwise (CW) or counter-clockwise (CCW) direction
•Two steps for scanning intensity
•Output relay contacts selectable as normally open or normally closed
•Two ranges of tolerance for "O.K." message
•Indication of the scanning result by two LEDs "O.K." and "K.O." on the control unit
•Detection of cable breaks

3System Components
3.1 Control unit
3.1.1 Characteristic properties
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.

These plugs may only be inserted or removed when the power supply has been
disconnected.

•"–" 24 VDC terminal
When using the internal control voltage, this terminal must be connected to the "Com" control
inputs terminal.
If an external control voltage is applied, this terminal is not connected.
Note:
2) Alternatively, "120 VAC" and "230 VAC" models may also be supplied with 24
VDC.
In this case, "L1" and "N" terminals must not be connected.
"+24 VDC" and "–24 VDC" terminals are to be connected as described above
for "24 VDC" model.
Control inputs
•"Com" terminal
Reference potential for control inputs and selection inputs
•"Start" terminal
An input level of +24 VDC relative to "Com" terminal will trigger a "Start" cycle
(the real scanning process).
•"Teach" terminal
An input level of +24 VDC relative to "Com" terminal will trigger a learning cycle
(the "Teach-in").

Selection inputs
•"S1" terminal
"S2" terminal
"S3" terminal
The input signal (static) of +24 VDC relative to "Com" terminal must be stable during 10 ms min.
before "Teach" or "Start".
The input S3 must be connected at a wand length of 250 mm. Concerning shorter wands, S3
remains unconnected. By connecting S3, the wand is slower and therefore it oscillates less.
S1/S2 selection inputs determine scanning direction !
The direction of scanning depends on connected scanner with corresponding switch position.
The meaning of "Clockwise/Counter-clockwise" toggle switch position on control unit may be
changed by corresponding S1/S2 input signals.
S1 and S2 may be open. Then is: S1=0, S2=0.

S1/S2 inputs change meaning of toggle switch.
2) Stop position must be defined by a “Teach-in” in both directions or by a
reference procedure in both directions. Missing stop position causes an error
message, and pulses on control inputs are ignored.

OI: BK MIKRO 7 BK Mikro 7 Manual
Rev. 2.00 dated 20.01.2006 Page15
Relay outputs
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).
•"K.O." relay terminals
These two terminals are used to indicate a fault message (K.O.).
•"O.K." relay terminals
These two terminals are used to indicate a no fault message, i.e. a good cycle (O.K.).
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.
3.1.4 Light-emitting diodes
Three light-emitting diodes (LEDs) on the front panel provide information about the current status of
the BK MIKRO 7 monitoring system:
•Power supply / Status
Yellow LED to indicate supply voltage and status
•"K.O." relay
Red LED to indicate fault message
•"O.K." relay
Green LED to indicate no fault message
•Error messages

3.1.5 Rotary switches
The two rotary switches P1 and P2 on the control unit front panel are used to
•select the scanning mode ("Teach" or "Switch").
•set the angular positions of the ranges, noted in degrees,
that are controlled by object monitoring or free space monitoring.
The position settings are possible in steps of 22.5°.
Fig. 3-4: Control unit–Rotary switches
The figure shows the setup on delivery.
The meaning of the rotary switches is determined by the selected scanner together with the
corresponding "Scanner" switch position.

"Scanning intensity" switch
Speed and force of scanner's wand in its scanning range.
For "Teach-in" and "Start" cycle, in case of a good message, they amount to:
"Scanning intensity" Impact Forces
switch position
approx. 200 mN
approx. 500 mN
The values are valid for a wand of 150 mm length, measured on its scanning tip.
Note: If this switchis in the "low" position, the lower impact force of the scanner will protect the
wand from wear and tear.
"Normally open contact / Normally closed contact" switch
Mode of operation for the two output relays (see section "Relay outputs").
"Object monitoring / Free space monitoring" switch
"O.K." result for
–finding an object (object monitoring) or
–not finding an object (free space monitoring) in the scanning window.
Note: Free space monitoring is admissible only in combination with range setting by rotary
switches P1 and P2 and connected scanner BK7SC with toggle switch
set to "BK7SC".
