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.

Note:

Default setting: S1 and S2 are not connected.

Scanning direction differs from "CW/CCW" switch setting:

S1/S2 inputs change meaning of toggle switch.

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.
