1. Introduction to the AF900PC

The AF-900PC is a state-of-the-art air/fuel ratio control system for single/dual bank,
spark-ignited, natural gas fueled carbureted engines. The AF-900PC incorporates
an extensive suite of advanced features that intelligently compensate for real-world
sensor and engine conditions.

This sophisticated system maintains the percentage of oxygen (O2) in the engine’s
exhaust gas stream by adjusting the amount of fuel to the carburetor(s). Fuel
valves mounted between the regulator and carburetor adjust the fuel pressure
applied to the carburetor to maintain the desired air/fuel ratio. The AF900PC is
designed to work with rich-burn engine systems using 3-way or NSCR type
catalytic converters.

In these applications it is very important to maintain air/fuel ratio to avoid damage
to the converter, prevent engine damage when fuel BTU content variations cause
the engine to run very rich or lean, and ultimately enable the engine to reduce
emissions.

2. Theory of Operation

Utilizing heated O2 sensor(s) in the exhaust stream (one per bank), the AF-900PC
provides PWM outputs to full-authority fuel valves in order to accurately control
air/fuel ratio over a wide load range. The O2 sensor operates best slightly rich or
lean of a point called stoichiometric, which is an A/F ratio of 16.09:1 for natural gas.
Engines with catalytic converters should be run slightly rich of stoichiometric for
lowest emissions.

The AF900PC implements compensation through an intelligent closed-loop
algorithm which provides smooth control behavior that is adaptable to changing
engine load, speed, fuel quality, ambient temperature and catalytic converter
conditions.

In addition, the AF900PC offers optional intake manifold pressure sensor(s)
capability for further adjustment of the post-catalytic setpoints, allowing the catalytic
converter to maintain emissions over an even wider range of engine loads and
operating conditions.

The AF900PC system monitors the proper operation of all sensor inputs and
controller outputs, flagging errors and changing its operating mode when a fault is
detected.

Equipped with a powerful onboard data logging feature and real-time clock, the
AF900PC has the ability to log controller conditions at either pre-determined times
of day or on a time interval basis. This allows users to automatically capture and
store diagnostic errors and overall system performance internally over any given
period of time. It also aids in troubleshooting hard to catch intermittent system
problems.

The MODBUS communications capability allows remote monitoring of system
performance and status.

6. Installation Details

6.1 Mounting the AF900PC Controller

The AF900PC Controller (Fig. 1) should be mounted at “eye level” in an accessible
location for easy display and keypad interface. The controller must be mounted in
surroundings where vibration is minimal and the ambient temperature does not
exceed 80 Deg C. A typical mounting location is on the side of the engine control
panel. A shock mount kit should always be used while mounting. All wiring enters
the controller through the bottom of the enclosure. There are three holes for ½”
conduit entry. All wiring is connected to the main board using removable terminal
blocks for ease of wiring and controller replacement.

NOTE: Installation requires four mounting holes.

6.2 Mounting the Heated Oxygen Sensor(s)

The heated oxygen sensor(s) should be mounted in the exhaust pipe as close to
the engine exhaust manifold as possible. A single bank engine requires only one
sensor. For dual bank “V” engines, the left and right bank sensors should be
mounted as close to the engine exhaust manifold as possible to eliminate cross
talk between the two banks.

CAUTION: The sensor(s) must be mounted where the temperature on the
outer shell does not exceed 400O F (204O C).

Above 400oF, sensor life will deteriorate rapidly and output voltage will be affected.
The sensor(s) should be mounted on a horizontal plane or above horizontal to keep
water from accumulating on the sensor tip. The sensor(s) should also be mounted
where they are accessible as sensor replacement is recommended every 2000
hours. It is recommended a fitting with 18mm x 1 ½ internal threads be welded into
the exhaust pipe for each sensor to be mounted. This will provide a flat mounting
surface for the sensor to avoid exhaust leaks. Sensors should be mounted with an
anti-seize compound on the threads.

NOTE: Recommended torque for mounting the sensors is 28 – 38 ft-lbs.
The conduit for the oxygen sensor should be routed to avoid close proximity to high

tensions ignition cables and coils to minimize potential EMI interference. Ignition,
flow control valve, and power wiring must not be placed in the same conduit with
oxygen sensor wiring. The conduit should also be routed where temperature does
not exceed 200oF.

6.3 Mounting the K type thermocouples (ungrounded must be used)

Optional thermocouples may be installed in the exhaust pipe to monitor pre and
post catalyst temperatures. The AF900PC will also calculate the differential (or
delta) temperature to help ensure proper catalyst operation. An NPT tap should be
used to tap the hole for the thermocouple. An adjustable fitting on most
thermocouple probes will allow proper insertion depth into the exhaust stream. The
thermocouples should be connected to the AF900PC terminal block using
thermocouple extension wire to eliminate erroneous readings.

6.4 Installation of M-201 Magnetic Pickup for Speed Sensing

The M201 magnetic pickup detects engine speed by sensing flywheel gear teeth as
they pass by. The pickup must be mounted on a bracket or flywheel cover so that it
is perpendicular to the face of the flywheel teeth it is sensing. The M201 requires a
5/8-18 UNF thread for mounting. The gap between the pickup pole piece and the
gear teeth should be set to 0.020” to 0.030”. Once the gap has been set, the pickup
should be secured with the lock nut. The M201 should be connected to the
AF900PC with a C101 pickup cable/connector.

8

6.5 Installation of the full-authority fuel valves (one per bank)

The full-authority fuel valves are to be mounted between the fuel regulator and
carburetor fuel inlet, as close to the carburetor inlet as possible.

7. Wiring the AF900PC Controller

All wiring to the AF900PC enters the controller through three (3) conduit openings
in the bottom and connects to three (3) double row terminal strips on the bottom of
the controller main board. The terminal strips unplug from the main board for ease
of controller wiring and replacement. The main board cover plate shows the
location of the terminal strips.

Wiring for terminal strip TS1 should enter through the left conduit opening.
Wiring for terminal strip TS2 should enter through the center conduit opening.
Wiring for terminal strip TS3 should enter through the right conduit opening. This

will separate the millivolt signal levels on TS1 and TS2 from the power, output, and
relay wiring on TS3.

8. Electrical Connections

The Fuel Valves must be configured for single demand, PWM control, and low side
drive.

10. Computer Interface using DynaHost Software

DynaHost software provides serial communication between a PC or laptop and the

AF900PC. DynaHost will run on a PC with 133MHz Intel Pentium processor, 32
MB of RAM, and a minimum of 100MB of hard disk space. DynaHost is compatible
with Windows 95/NT/98/2000/XP.

The AF900PC must be connected via a standard RS-232, 9-pin, male-female,
serial communication cable. The HOST software communicates
to the AF900PC via Dynalink, Dynalco Control’s ASCII-based serial communication
protocol.

When the program is running there are two major sections: the Control Panel and

the Current Screen.

10.1 Control Panel Specifications

OXYGEN SENSOR HEALTH SCREEN

The O2 Health Screen (Fig. 9) shows parameters related to sensor health
measurement.

Descriptions of the parameters are as follows:

EU: Displays the current voltage input from each O2 sensor.
ADC: Displays the A/D converter counts from the last sensor input measurement.
Test: Displays the A/D converter counts from the last sensor test measurement.
Raw: Displays the last calculated sensor health for each sensor.
Health: Displays the filtered sensor health for each sensor.
Filter: Programmable parameter sets the filter time constant for the sensor health.

With the maximum value of 1.0, there is no filtering and each sensor test becomes
the new Health value. With the default filter value of 0.01, each new sensor reading
becomes 1/100th of the Health value. In other words, a smaller filter value means
more filtering.
Time (sec): Determines time interval (in seconds) at which sensor health test will
be performed. Sensor Health test is performed every 60 seconds with the default
value of 60.

parameters you do not wish to data log. Enter “0” for the Chart # for any
parameters where an excel chart is not required.

NOTE: Parameters having no numerical value (such as Status) must be
assigned to chart # 0.

NAME shows the parameter name as it appears on the header on the excel

spreadsheet and on the excel charts. The names may be edited if desired.
If you wish to log a parameter not shown:

1. Enter the parameter number and index.

2. Enter the parameter chart #.

3. Enter the parameter name.

The parameter number and index may be found by placing the cursor over the
name of the parameter. The index is the decimal value of the parameter.

NOTE: Enter 255 for the index if the parameter does not have a decimal value.
Flash Memory: This section, shown at the bottom of Fig. 11 of the data log screen,

shows the status of the Onboard Flash Memory. “# Logs Stored” indicates the
number of data logs which have occurred since the last memory reset. “Capacity”
shows the maximum number of data logs required to fill the memory. To “reset”
memory, type “new card” in the Reset box and press enter. The flash memory will
be reset when the next data log occurs. All previously recorded data on the flash
memory will be lost upon reset.

NOTE: The following descriptions apply to the Trip 1 and Trip 2 Screens
TRIP SCREEN 1

A screen (Fig. 12) used to setup the trip action for pre-catalyst system faults. The
screen shows all faults set to Alarm and Data Log.

Trip Mode: Selects the action, from the drop down menu, which will be taken by
the controller when the fault occurs. To make best use of the system diagnostics, it
is recommended that all trips be programmed to Alarm or Shutdown so the
operator will be alerted if a fault occurs. Faults that are critical to the engines
health, such as high catalyst temperature, should be configured to Shutdown so
the shutdown relay contacts may be used to trip the panel annunciator.

Disabled (DIS): The trip is disabled and no action will be taken.
Alarm (ALM): Trips the Alarm Relay, flashes the Alarm LED, and shows the fault

on the LCD display.

Trip Screen 1

PRE-CATALYST CONFIGURATION SCREEN

This screen (Fig. 15) is used to set up the left and right bank pre-catalyst system.
The following section describes the function of every parameters located on this
screen. The parameters for the left and right bank are identical so they will be
discussed only once.

31

Pre-Catalyst Configuration Screen

Output Enable: This button enables or disables the left or right bank PI control

loop. One bank must be enabled for the controller to function.

O

Setpoint Req (V): Sets the initial target voltage for the left and right bank

2

Pre-Cat O2 sensors. Typically set between 0.700 and 0.900 Volts.
Start Percent (%): Sets the fuel valve opening when the controller is in the START
mode.

Manual Percent (%): Sets the fuel valve opening when the controller is in the
MANUAL mode.
Fault Percent (%): Sets the fuel valve opening when a pre-cat O2 sensor fault

occurs if the sensor fault select is set to FAULT.

32

Sensor Fault Select: Determines what control action will be taken if the pre-cat O2
sensor has a fault. Options are chosen from a drop down menu and are as follows:

Opposite: Sets the fuel valve opening the same as the opposite bank.
Fault: Sets the fuel valve opening to the value configured in the “fault percent

(%)” parameter.
MAP: Sets the fuel valve opening from the learn table based on current
manifold air pressure reading.
Start Temp (F): Controller changes from SENSOR WARM UP mode to AUTO
mode when exhaust temperature exceeds this threshold.
Off (Exhst Low) Temp (F): Controller returns to SENSOR WARM UP mode when
the exhaust temperature on either bank drops below this threshold. This parameter
is also used for “Exhaust TC Temp Low” trip.
Prop Gain: The pre-catalyst proportional gain parameter determines the gain of
the PI control loop. The larger the gain, the more aggressive the output changes in
response to errors. A typical of 0.020 is a good place to start.
Reset Time: The pre-catalyst reset time parameter determines the integration rate
of the PI control loop. The smaller the reset time parameter the faster the control
loop will integrate and increase or decrease the output while there is error. A typical
value of 5.0 is a good starting point.
Fast Dynamics: This button enables or disables the fast dynamic control function.
Fast dynamics are used to boost the proportional gain when a large error occurs.
Gain @ Fast +: Sets the proportional gain multiplier when in fast dynamics with a
Pre-Cat O2 sensor reading greater than the “O2 Setpoint Comp (V)”. A starting
value of 3.0 is suggested.
Gain @ Fast -: Sets the proportional gain multiplier when in fast dynamics with a
Pre-Cat O2 sensor reading less than the “O2 Setpoint Comp (V)”. A starting value of

3.0 is suggested.
Error for Slow: Sets the error voltage at which the PI loop will return to slow
dynamics. A starting value of 0.025 is suggested.
Error for Fast: Sets the error voltage at which the PI loop will go into fast
dynamics. A starting value of 0.050 is suggested.

enable post-catalyst control. This temperature should be set high enough to allow
proper catalytic converter action before post-catalyst control is attempted.

34

Min Post-Cat Comp: Sets the maximum allowable negative post-cat
compensation in millivolts. Post-cat integration will be frozen when this level is
reached. Typically set to –100.
Max Post-Cat Comp: Sets the maximum allowable positive Post-cat
compensation in millivolts. Post-cat integration will be frozen when this level is
reached. Typically set to 100.

Post-Cat Temp (F): Displays the current post-catalyst temperature value.
Pre-Cat Temp (F): Displays the current pre-catalyst temperature value.
Cat Delta Temp (F): Displays the current temperature differential across the

catalytic converter.
Filtered Delta Temp (F): Displays the temperature differential across the catalytic
converter after the time filter has been applied.
Filter Time (hours): Select the desired filter time for the FILTERED DELTA TEMP
from the drop down menu. Filter time is defined as the time required to reach 100%
of the new value when a change in delta temperature occurs. The filter is not linear.
Listed below is an example of the % new value reached at different points of the
filter time:
1/8 time ~ 37% 1/4 time ~ 60%
1/2 time ~ 85% 1 time ~ 100%

The following 4 parameters work together to establish the post-catalyst control
integration rate for pre-cat setpoint compensation when an error exists. The
association between these parameters is shown in the drawing on the configuration
screen on the following page.
Min Error (mV): Sets the minimum post-cat error voltage. No post-cat control will
occur when the error is less than this value. Set to 2.000 as a starting point.
Max Error (mV): Sets the post-catalyst error voltage for max rate post-cat
integration will begin. Set to 50.000 as a starting point.
Min Rate (mV/min): Sets the minimum post-cat integration control rate. Set to

valves are forced to START % allowing the engine to stabilize before attempting
automatic control. The minimum time is 0, maximum time is 300 seconds.
RPM Start Threshold: Sets the minimum engine speed on start for the engine to
be considered running. Minimum setting is 30 RPM. This parameter is used only
when using a magnetic pickup for speed sensing.

36

Pickup Threshold (mV): Selects the speed input voltage sensitivity from the drop
down menu. A setting of 1000 mV will work for most applications. At this setting a
minimum pickup input voltage of 1.000 peak ( 0.707 VAC RMS) is required. Used
only when magnetic pickup is used for speed input.
RPM Selector: Selects which speed input source will be used to determine that the
engine is running. When clicked ON, the speed contact closure will be used to
signal a run condition.

NOTE: Engine RPM cannot be displayed when using the contact closure
speed input.

When clicked OFF the magnetic pickup speed input will be used to determine
engine speed.

Relay Action Configuration:

The three drop down menus in this section determine the control action for the
Alarm, Shutdown, and Auxiliary Relays. Select the desired control action for each
relay from the description below:

NE: The relay is normally energized and will de-energize while in the tripped state.
ND: The relay is normally de-energized and will energize while in the tripped state.
LNE: The relay is normally energized and will latch in the de-energized state when

a trip occurs. The latched relay trip condition may be cleared by pushing the front
panel RESET key.
LND: The relay is normally de-energized and will latch in the energized state when
a trip occurs. The latched relay trip condition may be cleared by pushing the front
panel RESET key.

10.4 Communication Settings Dialog
This dialog (Fig. 18) is displayed when you click on the communication settings

label in the control panel.
The AF900PC is configured by default with the settings shown in Figure 18. The

settings can be recalled at any time by pressing the Defaults button.
Use this screen to change the COM port number to match the serial port being

used by your computer.

NOTE: All other parameters are fixed by the AF900PC firmware and changing
them will cause a communication failure.

Communication Settings

Figure 18

11. Computer Interface Using Configuration File

Another method used to configure the AF900PC is to edit and download a
configuration file to the AF900PC. The configuration file is a template file that
contains all configurable parameters and an explanation for all parameter
configuration settings. The user must enter desired configuration values for all
appropriate configuration parameters before downloading the file to the AF900PC.

The configuration file can be edited with any text editor or word processor that can
save files in text format, such as Wordpad available on Windows PCs.

The download file contains configuration comments and parameter configurations.
The comments for the configuration parameters explain the function for each
parameter and the programmable values associated for each parameter. The
comments are any text or text characters that follow a semicolon.

General AF900PC configuration comments should not be deleted. However, some
comments, such as ‘<ANALOG INPUT CHANNEL #01>’, have been included for
the user to overwrite with application-specific descriptors, such as ‘Engine Exhaust
Temperature’. Once the file has been edited, it should be saved under a different
name so that the original factory .spc file remains intact.

The configuration file’s parameter configurations program the corresponding
AF900PC parameters when the file is downloaded to the AF900PC.

38

11.1 Downloading a Configuration File

A list of parameters along with their values can be downloaded to the

AF900PC. The configuration file has a .spc file extension and is a plain ASCII text
file.

NOTE: An example of a configuration file is shown in Appendix A.

A semicolon character indicates the start of a comment. A comment can start

anywhere on a line. The end of line terminates the comment.
Parameters and their values are specified using the following format:
param_number = value ; comment
The parameter is specified by the ‘param_number’ argument, followed by an equal

sign and then the actual desired parameter value in the ‘value’ argument. An

optional comment can be added to describe what the parameter number

represents. The last line of the configuration file should contain a single ‘S’

character that must be sent to the controller. This command tells the controller to

store the parameters just downloaded.

CAUTION: DynaHost sends only the commands found in the configuration

file. If the ‘S’ is not present in the file, it will not be sent to the controller.

11.2 Uploading Configuration to an .spc file

It is recommended that a configuration file (.spc) with the current configuration of

your system be saved once the controller has been optimized for the installation.

This will provide a download file for other controllers used on similar engine types.

To upload a file, click the Upload button on the control panel of any DynaHost

screen. You will be presented with two dialog boxes; the first one is going to ask for

the ‘Source File’, which could be the AF900PC.spc file provided from factory. The

second dialog box is going to ask for the ‘Target File’ where you are going to save

40

the configuration. A file name such as the engine name may be used for the target,

but the name must end in “.spc”.

An upload report (Fig. 20) will open showing each parameter and it’s corresponding

value once data transfer begins.

12. Software Operation

12.1 AUTO Mode

After power-up, the AF900PC will begin operation in STOPPED mode

since most likely the RPM input will be zero. In this state, the controller completely

closes both the left and right bank fuel valves.

Once the AF900PC measures sufficient engine RPM (RPM>Startup RPM

parameter) or it detects the speed contact closure input present, it positions the left

and right bank fuel valves to their startup positions. This is now the START mode.

In the START mode the AF900PC waits for a timer to expire before changing into

the SENS WARMUP mode. Once in the SENS WARMUP mode the AF900PC

waits for the O2 sensors to warm up with the engine exhaust. During SENS

WARMUP mode the valves are held in the startup position until the left and right

bank exhaust temperatures are both above the threshold for the controller to go

into AUTO mode.

NOTE: If using heated O2 sensors, the threshold will be set to 0 Deg F,

enabling “AUTO” mode immediately following timer duration.

The delay timer in the START mode is setup in case a running engine shuts down,

then quickly re-starts while the exhaust is still hot. In this case, the delay timer will

allow conditions to stabilize before the controller further opens the fuel valves in

AUTO mode.

41

Once in AUTO mode, the controller waits for both pre-catalyst control loops to

stabilize and the pre-catalyst O2 setpoints to be within a small error before

introducing post-catalyst compensation. At that point the controller will be in its

final mode, AUTO/POST which is automatic with post-catalyst compensation.

12.2 MANUAL Mode

In MANUAL mode, the controller operates entirely in accordance with manually

entered parameter numbers, via DynaHost by the user. MANUAL mode may be

entered and exited only from DynaHost.

In MANUAL mode, the PWM output is determined strictly by the Manual Percent

(%) parameter(s). No automatic control takes place.

Note: It is recommended this mode only be used for troubleshooting by an

experienced user.

13. Control Software

The AF-900PC control software consists of two independent, identical left and right

bank pre-catalyst PI control loops. In addition, a separate post-catalyst offset

control section adjusts both the pre-catalyst loop setpoints in order to compensate

for actual catalytic converter behavior.

During initial system setup, the post-catalyst offset compensation is turned OFF

and the two pre-catalyst setpoints are adjusted until a separate emissions analyzer

shows that exhaust emissions are in compliance. At that point the post-catalyst O

sensor voltage is noted and used as the post- catalyst O2 setpoint. This way the

behavior of the catalytic converter is "captured" in the post-catalyst O2 setpoint.

Then the post-catalyst offset compensation is turned ON.

During normal operation, both the pre-catalyst loops will react faster to engine

changes and the slower post -catalyst offset loop will adjust the two pre-catalyst

loops based on factors which affect just the catalytic converter performance such

as fuel BTU content, temperature, load, etc...

14. Manifold Air Pressure Sensor (MAP) Load
Compensation (Option)

The AF-900PC is capable of accepting an input from a MAP sensor
in order to determine engine load. This option is needed for engines that operate
over a very wide load range and thus, one fixed post-catalyst setpoint does not
maintain emissions over the entire load range. If this option is used, the post­catalyst O2 setpoint is "offset" according to the engine load, which is proportional to
the MAP sensor output.

Up to ten offset points can be created for precise compensation in the high load
range. In the low load range, the base post-catalyst O
any offset. Only loads above "point zero" engine load (MAP) have any offset
added to the base post-catalyst O
catalyst O
load compensation begins.

In order to add MAP offsets, the user must enter SETUP mode by pressing the
SETUP key. When prompted for a Password, enter "1 2 3 4 " (or the correct
password if it has been changed from the factory default), and press ENTER.

A "Zero Point" must first be entered. Point zero is the starting point for MAP offset
compensation to begin. The "Zero Point" is the largest MAP load where the engine
remains in compliance with zero post-cat offset. To program "Zero Point" proceed
as follows:

setpoint never changes, but offsets are added to it once high engine

2

setpoint. At all engine loads the base post-

2

setpoint is used exclusive of

2

43

1. From the Setpoint menu, press the MAP Soft Key.

2. From the Map Programming menu screen, press the MAP Soft Key.

3. Once in the Map Programming screen, observe that the Offset is 0.000. If the

Offset is zero, proceed to step 5.

4. Press the Enter button and note the "Off" value is bracketed. Press Enter again

and note that "Off" is flashing. Use the Up and Down keys to set the value to
zero, then press Enter again.

5. To program the "Zero Point", press the MAP Soft Key, then the OK Soft Key.

The zero point is now programmed and will appear as Pt 1 in the post-catalyst
offset table in the DynaHost learn screen. Also note that Pt 1 was also entered
in the Valve #1 and Valve #2 learn tables.

The next step is to enter the full load MAP offset. Run the engine at 100% load for
a minimum of 15 minutes before entering the full load offset.

Proceed to enter the full load offset as follows:

1. Press the Enter button twice and note that the "Off" value is flashing.

2. Use the Up and Down keys to add or subtract post-cat offset. This offset is

immediately added to the Post-Cat Setpoint Req. When adjusting offset, allow
ample time for the AF-900 and catalytic converter to react to the changes.
Remember, the post-catalyst control loop is very slow.

3. Once full load emissions compliance has been satisfied, press the Enter key to

except the offset value followed by the Escape key. Next press the OK Soft
Key. The full load offset value has now been saved and may be viewed as Pt 2
on the post-catalyst offset table on the DynaHost learn screen. Also note that Pt
2 has also been entered in the Valve #1 and Valve #2 learn tables.

Additional points may be entered, one at a time, if the engine does not meet
emissions compliance at loads between the zero point and full load. Each point will
then have an offset amount and a corresponding MAP load amount stored in non­volatile memory.

Using DynaHost, the offsets at these points may be altered, but not the
corresponding MAP load amount at this point. The point must be deleted entirely in
order to alter the MAP load amount, in which case an entirely new point may be
added. No matter how many points are created, the points are connected in a
linear manner to provide a continuous offset amount.

15. Catalytic Converter Delta Temperature

The logic diagram below shows the operation of the catalytic converter differential
temperature measurement function. The pre-cat temperature is subtracted from the
post-cat temperature to obtain delta temperature. The "Filter Time" set on the Post­Cat Cfg screen is then applied to the delta temperature used for the trips. A trip will
occur if either the Delta Temp High or Delta Temp Low thresholds are exceeded,
provided the start timer shown at the bottom of the diagram has expired.

16. Data Logging

The AF900PC has powerful data logging capabilities through the use of on-board
Flash Memory, providing up to 64 Megabytes of capacity.

Up to 15 parameters can be logged as fast as every 1 second. Additionally,
ALARMS can be chosen for data logging as well as the AF900PC status
(MANUAL, START, AUTO, AUTO).

Using Dynalco’s Windows-based DynaTrend software, the user can transfer the
logged data to a laptop and view or graph the data. Dynalco’s DynaTrend software
can automatically and seamlessly open Excel to view and graph the data. Each
parameter logged is identified with a label and also a time/date stamp. Once the
data has been transferred to a laptop using DynaTrend, the file can be saved and
assigned a file name that can be the engine name/number/date, etc. with Windows
standard long filenames.

45

17. Setup

Using DynaHost and the data logging screen file (Fig. 21), the user can decide
which parameters are to be logged and how often or at what time of day. The set
up of this screen has been described in Section 10 of the manual.

Data Log Screen

18. Transfer

To transfer the data to a laptop, connect the RS232 DB9 connector to the
AF900PC and start the DynaHost software.

DynaTrend is the tool used to upload the data log information stored in memory.
The information is uploaded into a text file in the comma-separated values format
(.csv). DynaTrend also allows you to export the .csv file to Microsoft Excel.

DynaTrend software is initiated by clicking on the DynaTrend button at the top of
any screen. The steps to follow, which are shown in Figures 22 & 23, appear on
the computer screen. Once complete, the user is prompted to go to Excel for
presentation of the data.

All the information stored in the memory may be uploaded, or only the information
stored since the last time you uploaded.

19. Start Up Procedure

1) Before starting the engine, make sure the AF900PC is powered up.

2) The following AF900PC parameters need to be set prior to starting engine. It
is recommended to use the DynaHost user software main screen
configuration (see section 10.3) for setting the following:

• Manual Mode

• Valve output = 100%

• Gain = 50%

• Reset = 50%

• Post O2 sensor off

3) Since the AF900PC is in “Manual” mode and valve outputs are set to 100%
or full open positions, the fuel pressure will be the same as it was before the
AF900PC was installed.

4) Start the engine and allow to warm up to normal operating temperature.

5) Next, increase engine load to 100% or normal operating load.

6) Check the O2 sensor output voltage on each bank using either the front
display or using the DynaHost user software. This will give an indication of
where the engine has historically been running.

7) Set the O2 sensor setpoints to the same voltage read above.

8) Adjust the power screw adjustments on the carburetor(s) to full rich position.
The O2 sensor output voltages should increase.

9) Decrease the manual output settings slowly by 5% decrements until the O2
sensor output voltages match close to the readings taken in step 6 above. Be
careful not to lean the A/F too far as this could cause engine damage.

10) Switch to AF900PC AUTO mode. The AF900PC will now be controlling the
output fuel valves so that the actual O2 sensor outputs match the setpoints.

11) Install an emissions analyzer in the exhaust and fine-tune the LEFT BANK
SP and RIGHT BANK SP for the desired air/ fuel ratio. It is best to make
small adjustments (no more than 10 mV at a time) and allow engine time to
adjust before re-checking emissions.

12) The AF900PC will now control the air/fuel ratio to maintain the O2 sensor
output voltage established by by tuning the LEFT BANK SP and RIGHT
BANK SP.

49

When CONTROL LIMIT comes on during operation, it indicates that the AF900PC
cannot apply sufficient valve movement to obtain the desired air/fuel ratio under the
existing operating conditions. In this case, the engine’s fuel pressure regulator
spring or carburetor will have to be adjusted. If CONTROL LIMIT and LEAN are
on, the AF900PC output fuel valve is wide open and cannot increase fuel flow to
meet the O2 sensor setpoint. In this case the fuel pressure regulator spring
pressure must be increased or the carburetor enriched. If CONTROL LIMIT and
RICH are on, the AF900PC cannot decrease fuel flow enough to meet the O2
sensor setpoint. This would be unlikely and could be caused by a fuel valve
malfunction.

20. Diagnostics

The AF900PC has powerful self-diagnostics to detect and properly deal with
system and sensor faults. Below is a list of possible faults for which trips can be
enabled:
