Diagram 173: Assigning operations of a on-off switch to a turntable<br />

• Create a flagman “Track A” and assign the indicator “Track A” as trigger. This<br />

flagman is used to stop the turntable when the bridge reaches track “A”.<br />

• Assign the state “on” of the on-off switch “Track A” as condition to the flagman.<br />

In this way it is ensured that the bridge is stopped at track “A” only if it should do<br />

so.<br />

• Assign the command to stop the turntable as operation to the flagman.<br />

• Via the operations of the flagman the on-off switch “Track A” should be turned off<br />

again in order to return to the initial state.<br />

How it works:<br />

If the turntable is instructed to go to track “A”, then the on-off switch “Track A” is turned<br />

on. This on-off switch starts the bridge to move. When the physical bridge of the<br />

turntable reaches track “A”, the feedback indicator “Track A” is turned on. This again<br />

triggers the flagman, that is turned on, because the on-off switch “Track A” acting as a<br />

memory is still turned on. The flagman then stops the turntable.<br />
