9.000 seconds. When the limit switch goes ACTIVE, the examine 
period starts just like in the CAM MODE. However, once the 
examine period begins, the Die Sentry begins waiting for the 
specified probe TIME setting. At the end of the SET TIME, the 
examine period ends. The probe must still be seen as "ON" during 
the examine period or a probe fault will occur just as in the CAM 
MODE. The reported probe times are still the amount of time it took 
the probe to go "ON" after the examine period began. A normal 
case is given below.
