Overview
The AFR-64R and AFR-64L are available with the optional PV450 display mounted in the
controller’s enclosure, or the display can be purchased separately for remote mount. The same
display is used for both products. It automatically detects the product to which it is connected.
This display allows the user to view important controller parameters, clear alarms and temporarily
place the controller into Manual Mode allowing the fuel control valve position to be manually
manipulated. All other functionality (including initial setup) is performed with a Windows-based
laptop running the software that ships with each controller on the included CD. Please refer to the
main manual for the AFR-64R or AFR-64L for non-PV450 related information.

Main View
On the Main View screen, the user can monitor the operation of the AFR-64R or AFR-64L controller.

Staring at the top left corner of the Main View screen:
Engine Speed: Actual engine speed is calculated by the number of pulses per revolution
entered by the user during the system setup.
Fault and Warning Indicators: The yellow symbol is an indicator that the
fault relay has been activated and an active fault is present. The red symbol is
an indicator that the shut-down relay has been activated and a shut-down fault
is active.
O2 Sensor Phi Values: These are the values read from the Left Bank, Right Bank and Post-
catalyst oxygen sensors and are used to determine the air-to-fuel ratio of the engine by
measuring the excess exhaust oxygen concentration. If the engine is set up for a single bank
application, the Right Bank sensor value will read OFF. If the post-catalyst oxygen sensor is
turned off, the Post-catalyst sensor field will also read OFF. Note: the AFR-64L does not
have post-catalyst sensors; therefore, the Main View does not show this.
Target Values: These are the desired phi targets for pre-catalyst and post-catalyst control (if
equipped).
PreCat Phi Offset (AFR-64R only): This value indicates the amount of offset that has been
applied to the pre-catalyst target to achieve the desired post-catalyst target. This value is
only active if the post-catalyst sensor is used.
MAT - Manifold Air Temperature (AFR-64L only): The MAT gage shows the engine’s
manifold air temperature.
Catalyst Temperatures: The pre-catalyst and post-catalyst temperatures are displayed here
along with the calculated differential between the two (post-cat minus pre-cat). If the catalyst
thermocouples are not used, these values show ambient temperature inside of the
enclosure.
Valve Position: These values are the commanded positions for the Left Bank and Right
Bank fuel control valves.
Mode: This field will indicate whether the valve control is in Automatic or Manual. While in
automatic, the controller determines the valve position based on feedback from the oxygen
sensors. While in manual, the user determines the valve position. Manual valve control can
be accessed through the Main Menu. Note: Manual mode can only be entered while the
engine is running.
Press any button to access the Main Menu

Help Screens
Some screens will have a help button, which will provide contextually relevant information about the
given screen.
Main Menu Screens
From this menu, every point of interest of the controller can be accessed.
View Fault Screens
Active Faults
This screen shows all of the active or ongoing
faults. At the top of the screen is a quick
reference of the number of active and historic
faults. The active fault screen will show up to
eight concurrent faults. Any faults greater than
eight will be hidden.
Pressing the Historic button will take you to the
list of previous faults.
Pressing the Home button will return the user to
the Main Menu screen.

Section 40 00-02-0926

Historic Faults
The Historic fault screen is accessed through the
Active Fault screen by selecting the Historic
button. This screen shows all faults that have
occurred but are no longer active. Up to eight
most recent historic fault events can be shown.
Any number of faults greater than eight are
hidden. From here faults can be cleared.
Clearing Faults
Pressing the Clear button on the Historic Faults screen will purge all of the faults (both active and
historic), but all active faults will return within 10 seconds. (The controller displays an active fault on
both the active and historic pages. The
difference being an active fault will disappear
from the active fault page when the fault ceases
while it will remain on the historic fault page until
it is cleared or the number of historic faults that
have accumulated have exceeded eight in
number.)
Pressing the Active button will take you to the list
of active faults.
Pressing the Home button will return the user to
the Main Menu screen.
Switching toAuto Mode (Automatic Mode)
Selecting Switch to Auto Mode on the Main Menu will place the controller in Automatic Mode where
the controller monitors the signals from the oxygen sensors and manipulates the fuel controls valves
to maintain the air/fuel targeted set point (as opposed to Manual Mode where the user can manually
control the fuel valve position).

Viewing Targets Screens
View Pre-catalyst Targets Table
Selecting View Targets on the Main Menu will
display the Pre-Catalyst Targets Screen. Multi-
set point control is achieved through an 8 x 8
matrix of user set targets (using a laptop) from
which the controller interpolates a final set point
value.
Engine load is characterized by the intersection
of engine RPM (along the left of the table) and
manifold absolute pressure (along the top of the
table). A pre-catalyst setpoint is interpolated
from among the nearest four cells bracketing the engine’s current rpm and manifold pressure. The
resulting target is displayed in the upper right portion of the screen next to Pre Tgt (Pre Target).
On the AFR-64R, pressing Toggle Table on this screen will display the post-catalyst table which
behaves the same as the pre-catalyst table. Note: the Toggle button will not be present on the
AFR-64L because it does not use a post-catalyst sensor.
Viewing Post-catalyst Targets Table
On the Pre-catalyst Targets screen, pressing the
Toggle Table button will show the post-catalyst
table. Note: the Toggle button will not be
present on AFR-64L because it does not use
a post-catalyst sensor.
The post-catalyst table behaves the same as the
pre-catalyst table. The post-catalyst target
interpolated from the table is displayed in the
upper right portion of the screen next to Post Tgt
(Post Target). The post-catalyst target is used to
calculate a pre-catalyst target offset and is an advanced feature of the AFR-64R. See the main
manual for details.

Manual Valve Control Screen (Manual Mode)
Choosing Switch to Manual Mode from the Main
Menu will cause the controller to toggle to
Manual Mode and lock the valves into a fixed
position. The cursor will default to the left valve
and can be moved to the right valve using the
right arrow button.
Note: manual valve operation can only occur
while the engine is running. If the engine is
stopped, the controller will not allow a
manual valve position to be set.
Once the desired valve is selected using the left and right arrows, pressing the Edit button will take
the user to the adjustment screen.
The user can adjust the valve position up or
down using the + or –buttons. Pressing the
Done button will complete the adjustment and
take the user back to the Manual Valve Control
screen.
Note: The controller will remain in Manual
mode until either the engine is shut down (in
which case the controller will switch back to
Auto Mode when the engine is restarted) or
until the user selects Switch to Auto Mode
from the Main Menu screen.
Display User Setting Screen
From this screen the user can adjust the
Ambient Light and Brightness to the desired
setting.

Diagnostic Value Screens
On these screens, the user can view key values of the controller on one page:
Left Bank, Right Bank and Post-catalyst oxygen sensor voltages
Left Bank, Right Bank and Post-catalyst oxygen sensor health
Left Bank, Right Bank and Post-catalyst oxygen actual phi values
Left Bank, Right Bank and Post-catalyst oxygen phi targets
Left Bank and Right Bank valve positions
Engine RPM and Intake Manifold Pressure
Battery voltage at the ECM
Basic operational state of the system as well as the ECM run hours (Note: this is not an
engine hour meter.)
Software Version Info Screen
This screen shows software related information
that is loaded on the ECM and on the PV450
display.
The ECM serial number is also displayed.
