OI: BK MIKRO 7 BK MIKRO 7 with scanner TK7RL – Scanning in both directions

Rev. 2.01 dated 05.02.2007 Page 25 of 32

5.2.2 Control operation "Object monitoring"

The second "Start" pulse starts the real scanning process of object monitoring

within two ranges.

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.

 Both objects are detected within the rotation ranges P1 and P2.

The figure shows a "Start" cycle with setting:

Switch "R" and S1=0, S2=0, i.e.

first CW travel, then CCW travel of the scanner.

5.3 Scanning in one direction with scanner TK7RL

Requirement:

As soon as the stop position has been detected (i.e. after a "Teach-in" with

scanning in both directions or a reference procedure with scanning in both

directions) the scanning in one direction is possible with scanner TK7RL, too.

For scanning in one direction set the selection inputs S1 and S2 corresponding to the description

in table of section "Selection inputs".

Do not change setting of "Scanner" switch.

Teach mode

 Scanning in one direction of already "learned" objects

A "Start" will monitor both of the known objects individually:

Scanning in CW direction or in CCW direction.

 Scanning in one direction of "new" objects

Scanning in one direction allows also learning the position of unknown objects.

Stop position remains valid: The wand will return to its stop position, determined by

"Teach-in" in both directions, in any case.

Switch mode

 Scanning in one direction of the preset monitoring ranges

A "Start" pulse will monitor both of the monitoring ranges individually:

Scanning in CW direction or in CCW direction.
