Abstract: A programmable fastener press includes workpiece protection by utilizing punch position and punch contact sensors. The sensors signal a controller which classify portions of the punch's linear travel into multiple zones of operation. One zone is a stop window wherein any unwanted contact with the punch during its descent will cause the press to be halted and to remain stationary without being returned to home position. The press operator may, after correcting the fault condition, elect to instruct the press to proceed from the stoppage point downward continuing the normal operation of the press.
