2.1.5 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. 2-4: 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.

for scanner
TK7A:
P1=0
P2=0
Scanning using teach mode
P1  0
P2  P1
P2  270
Scanning after setting scanning range
(object monitoring and free space monitoring),
at which:
P1=start position (without tolerance)
P2=end position (without tolerance)
for scanner
TK7RL:
P1=0
P2=0
Scanning using teach mode
0<P1<360
0<P2<360
Scanning after setting scanning ranges
(only object monitoring, no free space monitoring),
at which:
P1=range CW (rotation from stop position)
P2=range CCW (rotation from stop position)
Ranges of tolerance selectable: ±3° and ±10°
Illegal switch settings
 P1=0 and P2  0 Error
 P1  0 and P2=0 Error
will cause flashing red and green LED.
Minimum angle = 5°
The minimum distance between the object and the wand must be an angle of
this value, so that scanning can start really, otherwise a "K.O." fault message
will be indicated.
