7.2 Preventing Device Table Collisions
Since the two device tables can work independently, an interlock is used
to prevent collisions when they are working in close proximity to each
other.
Two types of interlocks are used, one is in the software and the other is a
sensor on the machine.
The sensor is depicted in the following figure.
Fig. 7-2 Device Table Interlock Sensor
When the tables are approaching each other, a dog presses down on a
lever. This lever trips the sensor and causes the machine to stop.
