electrical protective device.
When the operator opens this door, the protective circuit will not allow the blast machine
to start or stops the cycle of the blast machine immediately. In order to start the machine, the
maintenance access door must be closed and the operator must "report" that he is now outside the
door clearing the alarm on the panel view.
