Automation Outputs - Graco PCF Instructions And Parts

Inlet Pressure
A 16 bit number indicates the current inlet pressure of
the fluid plate. Applicable in all control modes. Units of
this number are dependent on the pressure units.
Pressure Command
A 16 bit number indicates the current commanded pres-
sure of the fluid plate. Applicable in all control modes.
Units of this number are dependent on the pressure
units setting.
Flow Rate Command
A 16 bit number indicates the current commanded flow
rate of the fluid plate. Applicable in bead control only. In
pressure and shot mode, this value will be 0. It is always
in cc/min units.
Actual Flow Rate
A 16 bit number indicates the current actual flow rate of
the fluid plate. It is always in cc/min units.

Automation Outputs

Style
The desired style of the next job. These 8 bits are read
at the start of a job to determine the selected style.
Style Strobe
This bit is used to start a new job. A new job is started
when the style strobe changes from 0 to 1.
Dispense Complete
This bit is used to signal the end of a job. A job is ended
when this signal changes from 0 to 1.
Dispense Gun x On
These 4 bits are used to signal the turn on and turn off
of each of the 4 dispense guns on a fluid plate.
Command Value
This 12 bit value indicates the analog command value
from 0-10Volts. This analog value is scaled to a flow rate
(in bead mode) or pressure (in pressure or shot mode)
command based on the configured scale factor.
Fault Reset
This bit is used to clear an error in the system.
Remote Start / Purge
This bit is used to restart the dispense system from any
"not-ready" state. If the system is already in a Dispense
Ready state, this signal shall initiate a purge based on
the configured purge parameters.
