The external control interface allows an external machine to control the pr70f the external machine can use connector 1 to send dispense requests and abort commands also connector 1 indicates to the external machine whether the pr70f is ready to dispense connector 2 is used to select a shot number see fig ure 13 for the location of the connectors on the pr70f 53
The following conditions will make the machine not ready to accept a dispense request 53
The ready output status line ready output in figure 12 connector 1 pin 2 is a signal provided to the external control the line indicates whether a shot or dispense request will be accepted by the machine the output of the ready output status line is a high 24 vdc signal when the system is ready to dispense the output is a low 15 vdc signal when the system is not ready to dispense see figure 14 on page 53 for a sample timing diagram 53
