Interrupt Operation; Jam Detect Theory Of Operation - Pressure Seal PS 100 Manual

Interrupt operation

The PS100 stops during normal operation when any of the following occurs:
• Stop switch is pressed
• Power switch is turned off
• Top cover is removed
• Power cord is disconnected from source
• Feed table is emptied (infeed sensor not detecting documents)
• Document is mishandled in the folding plates
• Document is mishandled between folder and sealer
• Document is mishandled in the sealer (outfeed sensor blocked for more than
350 ms)

Jam detect theory of operation

The PS100's jam detection feature is controlled by a relationship between the
infeed sensor, the outfeed sensor, and the circuit board.
Each time the board activates the clutch, the outfeed sensor must detect a form
within a predetermined time, or the PS100 stops and the stop switch flashes. The
PS100 will detect a jam if a document remains over the outfeed sensor for longer
than 350 ms (about a third of a second) and again the stop switch will flash.
If the infeed sensor does not detect a form then the stop switch will be lit constantly.
