2.1.6 Toggle switches
Using the six toggle switches arranged next to each other on the control unit front panel, the
following functions may be set.
Fig. 2-5: Control unit – Toggle switches
Caution
Note:
Setup on delivery: All switches are toggled to the right !
When using scanner TK7RL: "Scanner" switch to the left !
"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"
switch position
Impact forces
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 switch is 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 TK7A with toggle switch set
to "TK7A".
