External Control Interface Setup
The external control interface allows an external
machine to control the PR70. The external machine can
use Connector #1 to send dispense request and abort
commands. Also, Connector #1 indicates to the external
machine whether the PR70 is ready to dispense.
Connector #2 is used to select a shot number. See F
IG.
33 for connector location on the PR70.
Ready-Output Status Line
The Ready-Output status line (“READY-OUTPUT” in
F
IG. 32, 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 F
IG. 34 on page 53 for a
sample timing diagram.
The following conditions will make the machine not
ready to accept a dispense request.
• Dispensing in progress.
• User is programming the display module.
• Active error code that has not been acknowledged.
• Auto-Sequencing in progress.
