NOTE
* These are basic PR70 models. Flow control would be added to these models based on your application.
Product Configuration
The PR70f offers a flow control feature that provides a
PR70 with the capability to dispense beads of material.
This flow control feature can only be used on PR70 con-
figurations that include the Advanced Display Module
(ADM).
Contact Graco Ohio Customer Service at
1-800-746-1334 to configure a PR70f for your applica-
tion. For general information about PR70 configurations,
refer to the Product Configurator section in the PR70
and PR70v with Advanced Display Module Operation -
Maintenance Instructions, manual 312759.
NOTE: The parts that differentiate the PR70f from a
standard PR70 are shown in Flow Control Parts on
page 60.
Hydracheck Option
The Hydracheck option regulates the speed or feed rate
of the pump. It is recommended that the Hydracheck
option is installed when using the flow control function.
Flow control performs best if the majority of the pump
restriction is external to the material flow (such as from
the Hydracheck adjustment) or is from a restriction in
the material path prior to the mixing point. See Figure 3
on page 8 for the location of the Hydracheck on the
PR70f.
Product Pump Selection
When selecting the pumps for the fixed ratio PR70f, you
need to know the material ratio, expected dispense flow
rate, and minimum programmed dispense amount. See
Appendix C - Product Pump Selection Guide on
page 67 for information that will help with selecting
pump sizes.

- 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
