Digatron’s DT-46K Instruction Manual

Introduction
Congratulations on the purchase of your new DT-46K. The DT-46K
is Digatron’s small, easy to use, multi-function, digital engine
monitoring system. This instrument was designed for the customer
who wants to know how their engine is functioning without spending
a lot of time and money. Depending on which version of this
instrument you purchased, it can monitor some or all of the
following functions: cylinder head temperature (CHT), exhaust gas
temperature (EGT) and tachometer (Tach). It datalogs all of these
inputs, along with lap times. Lap times can be stored manually or
with a beacon (if you bought the optional beacon receiver with
this instrument). All of this information can then be played back
on the DT-46K.
Included with your instrument is a simple instruction sheet
that allows you to quickly install and use your Digatron DT-46K.
The instructions in this booklet are more detailed to help you
learn all of the capabilities of your new instrument.

Installing Your Sensors and
Batteries
These instructions cover all the sensors that can be used with
the DT-46K. Some may not pertain to your particular model.
Do not operate your DT-46K unless all the sensors are
connected. Inputs that are left open can cause erratic readings
and possible instrument damage. Any unused instrument inputs,
except the Lap switch, must be terminated at the back of the
instrument with a shorting plug available from Digatron.
Sensor cables that run from the engine compartment to the
instrument should always be routed as far away from the ignition
system components as possible (plug wires, spark plugs, ignition
coils, distributor or magneto). Sensor cables too close to these
components may pick up radiated electrical interference and cause
erratic instrument readings and operation. A distance of at least
6" from these components is
desirable in all installations.
When routing sensor cables through any panels, be sure to use a
rubber grommet to keep the cables from being cut by a sharp edge.
It is also good practice to protect all of the sensors with a
short piece of fuel line at any point that the cable may rub
against a hard surface.
If any of your cables are too long to route back to your
instrument fully extended, we recommend sending your sensors back
to Digatron to be cut to the appropriate length for your needs or
coiling them each separately. If you do coil your sensors, keep
the coils away from the engine.
Installing Your Tach
Sensor
Our standard Tach sensor can be installed
on both two and four cycle engines.
Use a cable tie on the shrink tube, at the end of the green
wire, to attach the sensor to the plug wire, keeping the end at
least 2" from the plug boot.
Keep the sensor electronics (red) away from any ignition
component. If you experience erratically low Tach readings, attach
the green wire, inch by inch, to the plug wire until you have
correct readings. Attach the end of the black ground wire to the
bare metal on the engine block. Route the sensor cable from the
motor to the rear of your instrument and secure with cable ties.
Plug into the pigtail with the "push-on" type connector.
For best results, keep the Tach sensor cable separated as much
as possible from any other cables running to your instrument.
Installing Your CHT
Sensor
Our standard CHT sensor is for air cooled
engines only. For temperatures consistently above 450º
F we have a thermocouple sensor.
Remove the spark plug from the cylinder you wish to monitor and
discard the plug washer. Check the surface of the head around the
spark plug hole for a smooth, flat finish to assure a good seal
when the sensor is installed.
Position the sensor over the spark plug hole and check that you
have sufficient clearance around the outside of the sensor body to
avoid damage when the plug is installed and tightened. This may
require some minor machining on some installations.
Install the spark plug finger tight to hold the sensor in
position. Finish tightening with a plug wrench to the same torque
as normally recommended. Do not allow the sensor to turn as you
tighten the plug. The sensor is easily damaged if forced into
a cooling fin.
Route the sensor cable from the motor to the instrument. Secure
the cable to the frame of the kart with cable ties. Connect to the
small, threaded pigtail on the instrument and turn the connector
until tight.
Installing Your EGT
Sensor
Our standard EGT sensor is a type K
thermocouple temperature sensor. Install the sensor clamp
assembly, or weld on, to the exhaust header. Position the clamp so
that the sensor will be in the center of the header and
approximately 2" from the head
side of the exhaust flange. Using the fitting on the clamp
assembly as a drill bushing, drill a 3/16"
hole through the header. Remove the clamp assembly from the header
and redrill the hole to 13/64" .
Reinstall the clamp assembly aligning it with the hole just
drilled.
Insert the sensor into the fitting so that the tip of the
sensor extends ¼" past the
center of the header. Tighten the compression nut to lock it in
place. Connect the black wire to any clean, unpainted metal
surface on the engine (it is important that this is a good
electrical connection).
Route the sensor cable from the motor to the instrument. Secure
the cable with cable ties to prevent excessive movement. The
thermocouple cable is brittle and will break at the flex points if
not properly tied down. It is also good practice to
protect the cable with a short piece of fuel line at any point
where the sensor may rub against a hard surface.
Mounting Your Lap Switch
(for Manual Lap Time Only)
The Lap switch should be mounted to the
steering wheel within thumbs reach of the driver. This switch
requires a 15/32" mounting hole
for installation. Mount the switch in a position that will provide
easy access while driving.
Tie the coil cord to the steering column where needed to
prevent it from interfering with the driver. If the Lap switch is
not used, leave it’s input connector open; do not use a shorting
plug.
The DT-46K Uses Three AAA
Batteries (not included)
The DT-46K is powered by three AAA
batteries. These allow the instrument to run for 100 hours with
the backlight on and 500 hours with the backlight off.
Replacing the batteries is simple. With the front of the
instrument facing you, remove the left end cap. Slide the battery
pack out from inside the unit and replace the batteries. Slide the
battery pack back into the instrument, making sure that the batteries
are facing the back of the unit. Replace the end cap and you
are done.
Turning Your DT-46K On
There are two ways for your instrument to be powered on:
The unit will turn on and begin recording automatically when
the engine is started.
The unit can be turned on with the Exit/Power
button before the engine is started. It will then begin
recording when the Lap switch is pressed or it passes a beacon
(if you purchased the optional beacon receiver). Also, when the
engine is running, the Exit/Power button can start
and stop recording.
Note:
When the instrument is first powered on,
it is always in the Monitor/Record mode.
Display Resolution
When the instrument is powered on, the display is in high
resolution. This means that it shows time in tenths of a second
and the highest number that can be displayed is 1 minute, 59
seconds and 9/10s of a second. After that time, the instrument
continues to record, and the 1 on the left of the display toggles
every other minute.
To change the display to low resolution, press the ¬
and the ® button at the same time,
while in Monitor/Record mode. In low resolution, the instrument
can display up to 19 minutes and 59 seconds. The instrument will
continue to record beyond that amount of time, but the 1 on the
left of the display will toggle every 10 minutes.
The Three Modes of the DT-46K
This instrument has three basic modes of operation, Set Limits,
Monitor/Record and Playback.
Set Limits mode is necessary before using your unit for the
first time and if you use it on different engines. Limits help
you prevent possible engine damage.
Monitor/Record mode is used while you are on the track,
during races or practice.
Playback mode allows you to review all of your recorded data.
This information is played back to you on the display of your
DT-46K.
A. Setting the Function Limits On Your DT-46K
Before using your DT-46K, be sure to set the operating limits
for each input. Limits allow the instrument to give you a visual
warning (the display flashes) if any of the inputs exceed their
limit. Limits should be set at levels that allow you to react
to the visual warning before engine damage occurs.
Set Limits mode can only be entered from Monitor/Record mode,
which is the mode the instrument is in when powered on. Enter Set
Limits mode by pressing the ® button.
The instrument is now in Set Limits mode, which is indicated by
the flashing display.
To change the number being displayed press the ¬
or the ® button. Hold either of
these buttons down and the number will change faster.
When you are finished setting the first limit, press the Function
button to set the next limit.
Repeat the above procedure to set the remaining limits and
the Tach calibration number.
To save the current limits and return to Monitor/Record mode,
press the Exit/Power button.
Note:
Set limits at levels high enough for normal operation, but not so
high that engine damage can occur before you can respond to a
problem.
Limits can only be set for the functions your gauge is designed
to monitor. If your gauge monitors all three possible functions,
the limits are set in the following order: CHT, EGT, Tach and Tach
calibration number. If you do not have all of these functions, it
will also set limits in this order, minus the function(s) you are
missing. Tach requires two separate parameters. The first is the
maximum revolutions per minute (RPM) for safe engine operation.
The second number is for Tach calibration. In order to display the
correct RPM for different engine types, the instrument divides the
Tach input signal by the Tach calibration number. This number can
be between .5 and 31.
The most frequently used numbers are:
.5 - for some single cylinder 4 cycle motors
1 - for single cylinder 2 cycle and some 4 cycle motors
2 - for 2 cylinder 2 cycle and 4 cylinder 4 cycle motors
If you are unsure of the exact Tach calibration number for your
engine, experiment. If your calibration number is currently set at
1 and the RPM displayed is double what it should be, set the
calibration number to 2. Alternately, if the RPM displayed is half
of the correct value, decrease the calibration number to half the
current number.
Setting minimum lap time
(Ignoring Multiple Beacons)
The last number you can set in Set Limits mode is the
minimum lap time.
Setting the minimum lap time allows the instrument to ignore
multiple beacons on a track.
After this minimum lap time has passed, the next beacon
signal received will trigger a new lap in the memory of the
instrument. Valid times are
from .1 second to 199.9 seconds. Use this setting to keep your
instrument from storing a lap for every beacon on the track. You
should enter a time that is barely under the fastest lap time you
expect to do.
About Cylinder Head
Temperature
Cylinder head temperatures (CHT) usually
run in the 300º F to 475º
F range. The best way to determine the correct temperature for
your particular motor is to tune for proper plug or piston color
and then observe what the head temperature is for various throttle
settings and atmospheric conditions.
Temperatures consistently over 450º
F will damage the standard CHT sensor. If your motor frequently
runs at cylinder head temperatures over 450º
F your instrument should have an exhaust gas temperature function,
which can use a thermocouple CHT sensor. This sensor can be used
without damage at higher temperatures, but it is not as accurate
as our standard CHT sensor.
About Exhaust Gas
Temperature
Exhaust gas temperature (EGT) is used
primarily for adjusting the air/fuel ratio. Because of its quick
response, the effects of carburetor adjustments are seen
immediately. Fuel system and carburetor problems can often be
spotted quickly enough to prevent engine damage.
Exhaust gas temperatures typically run between 1100°
F and 1350° F. The EGT on a properly
tuned engine will increase rapidly as the throttle is opened and
as the load on the engine is increased. At full throttle and full
load the EGT will stabilize at a temperature dependent on the
air/fuel ratio. Both a "too lean" or a "too
rich" condition will be indicated by a lower than peak
temperature. The "too lean" condition can damage your
engine. An increase in coolant temperature or cylinder head
temperature is usually an indication of this. The best way to
determine what temperature is normal for your motor is to tune for
good plug or piston color and then observe the temperature at
various throttle settings.
How the Tachometer
Reading is Displayed
The Tach displays RPM in thousands of
RPM. For example, if your display shows 9.50, your RPM is 9500.
B. Monitor/Record Mode is Used While on the Track
When your instrument is powered on, it is in Monitor/Record
mode. This is the mode the unit will be in during the Event (race
or practice) so you can observe and record your engine functions
and lap times. This information is recorded for review in Playback
mode.
Note: The
memory of this instrument holds 35 minutes of information. After
that amount of time, the instrument will keep recording and begin
writing over previously recorded data.
During Monitor/Record mode you can make quick tuning
adjustments to your engine that allow you to run safe and fast.
The instrument will visually warn you, by flashing the display, if
your engine exceeds any of it’s set limits. These limits allow
you to avoid engine damage.
Recording information is very simple. Once you have started
recording, you can change what function is being displayed. Laps
are recorded manually with the Lap switch or automatically when a
beacon is passed, if you have a beacon receiver.
These are the buttons used to start recording, change what is
being displayed and stop recording:
Press the Exit/Power button, Lap switch or pass
a beacon to begin recording. (The beacon method only works if
you have a beacon receiver.)
Press the Function button to change what is
being displayed. It toggles through the functions in this order:
CHT, EGT, RPM, Lap # and Lap Time. (Not all instruments have all
of these functions.)
Press the Exit/Power button, or turn your
engine off, to stop recording and end the current Event.
There are two other buttons that can be used in Monitor/Record
mode:
The backlight is used to illuminate your display for use at
night. Press the ¬ button to toggle
the backlight on or off. The backlight can only be turned on or
off while in Monitor /Record mode.
The Max/Event button is used to display the
maximum reading for each engine function and the Event number in
progress. If the instrument is displaying an engine function and
you press the Max/Event button, it will display
the maximum reading for that function since the instrument was
turned on. If the instrument is displaying Lap # (display shows
L and two or three numbers), and you press the Max/Event
button, it will display the current Event number (display shows
E and two numbers).
Ways to Begin Recording
There are three ways to begin recording
data:
Starting the engine while the instrument is turned off,
automatically starts the instrument and begins recording the
Event.
Manually turn the instrument on with the Exit/Power
button before the engine is started. Press the Lap switch or the
Exit/Power button to begin recording. (The
instrument must be receiving a Tach signal to begin recording
with the Exit/Power button. If it does not have a
Tach signal, pressing this button will turn the instrument off.)
Manually turn the instrument on with the Exit/Power
button before the engine is started. When the kart passes a
beacon, the instrument will begin recording, if you have a
beacon receiver.
Information about Recording
Each time you press the Lap switch or
pass a beacon while recording, the current lap stops and a new lap
begins. (The beacon receiver that can be bought to go with this
instrument recognizes both Digatron and My-Chron beacon signals.)
When you finish a lap, while the instrument is recording, it
will display the total time for the last lap for three seconds,
before returning to the previously displayed data. If you are
displaying Lap Time while recording, the instrument will
continuously display the time of the last lap. To show running
time for the current lap, press the Max/Event
button. When the clock is running, a colon will flash in the
display.
Turning off the engine or pressing the Exit/Power
button terminates the current lap and the current Event. A new
Event is started when the instrument starts recording again. When
the unit is turned off, it does not lose it’s data. When it
begins recording again, it will start a new Event, on lap one, at
the end of the last recorded Event. After 35 minutes of total
record time, the instrument will begin recording over previously
recorded data.
Note:
The instrument will not record while the
PRS (PReviouSly recorded data) annunciator is
visible on the left side of the display. The PRS annunciator shows
that the instrument is in Playback mode. Press the Exit/Power
button until PRS is not displayed to return to Monitor/Record
mode.
Reset Lap and Event
Number and Clear Memory
To reset the lap and event number to zero
and clear all recorded data, press the ¬
and the Max/Event buttons. When the display flashes
PrS PLA, press the Play/Pause button. The memory is
now clear. If the Play/Pause button is not pressed
within 5 seconds, the reset function is aborted.
Note: The
memory is not automatically reset when you turn the
instrument off. All data is retained when the instrument is turned
off and even when the batteries are removed.
C. Playback Mode is Used to Analyze Lap Data
Recorded information is reviewed in Playback mode by lap. There
are two levels in Playback mode, Lap/Max and Function Playback. In
Lap/Max, you view lap times and maximum values for each function
during that lap. During Function Playback you review each lap’s
information in detail.
Note: PRS
(PReviouSly recorded data) is visible on the left
side of the display during both Lap/Max and Function Playback.
Lap/Max Shows Lap Numbers
and Maximums for Each Lap
Lap/Max is the first of two levels in
Playback mode. Lap numbers and maximum values for each lap are
reviewed in Lap/Max. Lap numbers are represented by an L on the
display. You must change to the desired lap in Lap/Max before
reviewing the information available in Function Playback.
When in Monitor/Record mode, press the Play/Pause
button to enter Lap/Max.
Press the ¬ or ®
button to change the lap number being displayed. If you are
viewing the last lap of an Event, the ®
button moves you to the first lap of the next Event. If you are
at the first lap of an Event, the ¬
button moves you to the last lap of the previous Event.
Note:
If your display shows the word LooP after pressing one of the
arrow buttons, this means that it is searching for the beginning
of the next lap’s information.
Press the Function button to review the maximum
values for the different functions during this lap.
Press the Max/Event button to see which Event
you are reviewing. (The display will show E and two numbers.)
To turn off Lap/Max and return to Monitor/Record mode, press
the Exit/Power button.
Function Playback Allows
Detailed Review of a Lap
Function Playback is the second of the
two levels in Playback mode. In Function Playback you can review
all of the detailed information recorded for the lap that was
selected in Lap/Max. The information can be played back, for each
function recorded, in real time or stepped through in 0.1 second
increments.
When in Lap/Max, press the Play/Pause button to
enter Function Playback and begin reviewing the data for the lap
that was selected in Lap/Max. The instrument will begin playing
back the time for the selected lap.
Press the Play/Pause button to pause the
playback of data and again to resume playback. (The information
for this lap will continue to replay until this button is
pressed.)
Press the ¬ or ®
button to change the direction of playback. If playback is
paused, use the arrow buttons to step through the data in 0.1
second intervals.
Press the Function button to view the different
functions’ readings for this lap.
Press the Max/Event button to review the
maximum readings for each function, the current Event number or
the total lap time for the current lap, depending on what
function is being displayed.
To review a different lap’s data, press the Exit/Power
button to return to Lap/Max. While there, use the arrow buttons
to select a different lap. Then press the Play/Pause
button to begin reviewing data for the newly selected lap.
Press the Exit/Power button to return to
Lap/Max.
Turning Your Instrument Off
The unit can be turned off by pressing the Exit/Power
button while it is in Record/Monitor mode (if there is no Tach
signal and it is not recording). The instrument will turn itself
off automatically after ten minutes if no keys have been pressed
and there has been no tach signal.
Note: All
data is saved when the instrument is turned off.
Electrical Interference
If the instrument encounters excessive electrical interference
it will display ERR on the left side of the display. This
indicates that the stored data might be invalid. Press the Function
button, then turn the instrument off for 30 seconds. Now check if
it is working properly. If it is not, turn the instrument off and
back on again. Immediately after turning the instrument on press
the ¬ and the Max/Event
buttons. When the display flashes PrS PLA, press the Play/Pause
button. The error and memory should now be cleared.
The ERR annunciator can also indicate an incorrect instrument
or sensor installation. Severe electrical interference can cause
the limits and calibration to reprogram themselves. If your
instrument is doing strange things, put it in Set Limits mode and
check to see that the limits and calibration are still where you
set them.
Electrical interference problems can normally be solved by
installing a resistance plug boot. We recommend using an
NGK boot, # LB05EMH.
To avoid erratic readings:
Keep your temperature and Tach leads separated by at least 3"
. Do not wrap leads together, this can induce
interference into the system.
Route the leads as far away from the coil as possible.
Install the Tach lead on the plug wire at least 2"
back from the plug boot. If you still have a problem, try a
different location on the plug wire.
Running your leads through separate sections of fuel line
will protect them from cuts and abrasions, but will not
shield them from ignition generated interference.
Be sure that all sensors are connected
to the instrument, and that all connectors fit together snugly.
If a sensor is not being used, the input at the back of the
instrument must have a shorting plug, which is available from
Digatron.
Troubleshooting
The following are explanations to some commonly asked
questions.
What are those letters on
the side of my display?
There are five annunciators that may be
displayed on the left side of your display. The most common ones
represent the engine function being displayed at that time:
CHT stands for Cylinder Head Temperature
EGT stands for Exhaust Gas Temperature
RPM stands for Revolutions per Minute, also called Tach
There are a couple other annunciators that do not stand for
engine functions.
PRS stands for PReviouSly recorded data and
signifies that the instrument is in Playback mode.
ERR stands for Error and could mean that your instrument
has encountered extreme electrical interference. This can ruin the
recorded information and possibly cause the instrument to
reprogram it’s limits and calibration values.
Why does my instrument
only record for 2 minutes?
Your instrument will record for longer
than 2 minutes, but your display has a limit to what it can show.
The instrument has two resolution levels, high and low. High
resolution shows tenths of a second, and can display up to 1
minute, 59 seconds and 9/10s of a second. The 1 on the left of the
display toggles every other minute in high resolution. Low
resolution does not show tenths of a second, but it displays up to
19 minutes and 59 seconds. The 1 on the left of the display
toggles every 10 minutes in low resolution. To change the
resolution of your display, press the ¬
and the ® button at the same time,
while in Monitor/Record mode.
Why does my display keep
saying LooP?
This means that your instrument is
searching for data, usually the beginning of a lap during Playback
mode.
Why does my lap number
have a 1 in front of the L?
If your display shows 1L and two other
numbers, it means that you have recorded over 100 laps during the
current Event.
Why is the colon ( : )
flashing?
This signifies that the clock is running,
either during record or playback.
Why is the Display
Flashing?
This signifies that you are either in Set
Limits mode or that your engine exceeded a set limit.
Why won’t my instrument
record?
The instrument will not record if it is
in Playback mode. If PRS is displayed on the left side of the
display, your instrument is in Playback mode. Press the Exit/Power
button until PRS is no longer displayed and then you can begin
recording.
Why won’t my instrument
respond when I press a button?
The computer in your instrument needs to
be reset. It should still respond to the Function
button. Press this button, then turn the instrument off for 30
seconds. Turn the instrument back on and check to see if it is
working properly. If it is not, turn it off and on again.
Immediately after turning it back on, press the ¬
and the Max/Event buttons to reset the
instrument. When the display flashes PrS PLA, press the Play/Pause
button. If you had to reset the instrument, all of your previously
recorded data was erased, but it should now be working properly.
