Operating instructions

OI: BK MIKRO 7 BK MIKRO 7 with scanner TK7A – Scanning in one direction
Rev. 2.01 dated 05.02.2007 Page 19 of 32
4.2 Switch mode = monitoring with setting scanning range
Requirement: Rotary switches 0  P1  P2  270
Rotary switch P1 and P2 settings will define the scanning range.
In this mode of operation, BK MIKRO 7 is suitable for monitoring tools with differing diameters
(object monitoring) as well as for ejection monitoring (free space monitoring):
Two rotary switches are used to define a scanning range which is to be monitored before
each working cycle.
Note:
A Pulse on the "Teach" terminal do not take effect.
4.2.1 Control operation "Object monitoring"
Using "Object monitoring", the control unit will change into an "O.K." state, i.e. it will issue a good
message, if during a scanning cycle the operation sequence described below is followed:
 The scanner leaves its stop position.
 The angle preset via rotary switch P1 has been exceeded.
 The angle preset via rotary switch P2 has not been reached.
4.2.2 Control operation "Free space monitoring"
The control operation "Free space monitoring" differs from the object monitoring mode in that
within its monitoring range no object must be detected.
Its "O.K." state is characterized by:
 The scanner leaves its stop position.
 The angle preset via rotary switch P2 has been exceeded.
Caution
Caution:
When performing "Free space monitoring", broken wand will always trigger
an "O.K." signal.
Note:
 "Scanning intensity" toggle switch set to "high" will enable scanning operation
at a higher speed.
 Life expectancy of the wand will not be reduced, since the unit will rarely contact
a part using "Free space monitoring".
