Description 

PB-507 provides two open-collector output pulsers, each with 1 normally-open 
(NO) and 1 normally-closed (NC) output. When the pushbutton is released, the 
circuit is in NC state, and when the pushbutton is pressed, the circuit is in NO 
state. The corresponding green led will light. 

6.6  Logic switches 

Front-panel controls 

Figure 10

 shows the Logic switches controls on the front panel of the trainer.
