Installation ST700 Dash Display System
INSTALLATION
You do not need complicated tools or special training to install the ST700
Dash Display System. To gain the benefits of using this quality instrument all you need are a few basic workshop tools, the willingness to
read and follow these instructions carefully and the time to complete
each task in sequence.
Refer to the instructions between page 43 and page 59 for instructions to set up the ST700 Dash Display System display and alarm limits specifically for your vehicle.
Product Installation
The installation process begins when you start to install the wiring harness, the controls and the ST700 Dash Display System display. After you
have completed these tasks, you can fit and connect the options and
sensors included with your system. You may then connect the ST700
Dash Display System to the vehicle electrical supply.
You will need to cut a hole into the instrument panel to accept the ST700
Dash Display System instrument display. Choose a suitable position for
it:
❑ Mount the ST700 Dash Display System display on the instrument
panel so that the driver can see it easily, looking either through or
over the steering wheel, as shown in Figure 1.

display location
❑ Position the ST700 Dash Display
System display so that the driver
can see it either square on or
from a position slightly above.
Figure 2: Overall dimensions
❑ Make certain there is suffi-
cient space behind the instrument panel to accept the ST700
Dash Display System display.
Allow additional space so that
you may run and connect the
wiring harness without the
need to apply sharp bends to
the harness.
Figure 2 shows the overall dimensions of the ST700 Dash Display System display, which fits into a standard 80 mm diameter hole.
Wiring Harness
Stack supplies a wiring harness to connect the ST700 Dash Display System within the vehicle. If you find that the standard wiring harness is
unsuitable for installation on your particular vehicle, contact Stack or an

approved Stack agent for details of wiring harness extensions. Labels
identify each wire in the harness shown in Figure 3.
1. Identify all the relevant connectors of the wiring harness.
2. Plan the location of all the component parts of your ST700 Dash Display System and decide the best layout to use when you install the
wiring harness.
Note that your installation might not use all the cables that exist in the
harness. You should tie back and protect all unused connectors.
3. Begin at the instrument panel where you will install the ST700 Dash
Display System display. Lay the wiring harness into the vehicle,
with the cable branches running to their appropriate locations.
Allow sufficient slack in the harness so that you can connect it to the
ST700 Dash Display System before you insert the display into the
instrument panel.
You should route all cables to be no closer than 75 mm (3 inches) to
the ignition HT leads or the distributor cap. Do not run cables close to
sources of intense heat.
4. Fit cable glands to protect the cables where they pass through bulkheads or panels. This is particularly important when you pass cables
through carbon fibre partitions, which can wear through them easily.

Controls
The ST700 Dash Display System includes three controls:
❑ Driver button—this is a normally–open spring–loaded switch that
closes when pressed and opens when released.
❑ Rotary control—this is a combined push button and rotary selector.
❑ Lap button (optional)—this is a normally–open spring–loaded
switch option that closes when pressed and opens when released.
For convenience, you should install the controls where the driver may
operate them easily. An ideal installation for the Driver button and for
the optional Lap button is on the steering wheel within easy reach of a
thumb.
Install the rotary control where it is possible to operate it conveniently
while viewing the ST700 Dash Display System display.
1. Drill holes or install brackets to support the controls in the locations
you have selected for them. The hole dimensions and tightening
torques are:
Rotary control: M7 clearance (7.2 mm diameter) with the control
tightened to 1.2 Nm (12 kgf.cm or 0.9 lbf.ft)
Driver button: 12.2 mm diameter with the control tightened to 1.5
Nm (15 kgf.cm or 1.1 lbf.ft)
2. Connect the correct cables of the harness to each control.

Engine Speed Measurement
This connection is dependent on your ignition system. You should
read these instructions carefully and make certain you have identified
the correct connection point before you begin.
To measure engine speed you must make the correct connections between the ST700 Dash Display System and the vehicle ignition system.
Contact Stack for advice if you have a complicated ignition system.

Lap Timing Sensor option
The lap-timing sensor triggers the ST700 Dash Display System automatically each time the vehicle passes the Stack infrared (IR) beacon at the
side of the track.
1. Choose a location on the vehicle for the lap-timing sensor:
Figure 7: Lap timing beacon
❑ You must position the sensor
to be horizontal and square
to the vehicle axis.
❑ It must have a clear view of
the trackside beacon, even
when you overtake or are
overtaken by other vehicles.
❑ Do not mount the sensor
behind glass or Perspex.
❑ The sensor must be at the
same height as the beacon.
As shown in Figure 8, you can
adjust the height of the beacon to achieve this condition.
16
Page 21
ST700 Dash Display System Installation
❑ You may need to have more than one possible location available
for the lap-timing sensor on your vehicle to allow for the layout
of different tracks. Consider installing one on each side of the
vehicle.
❑ Where the track has more than one trackside beacon, you may
set up the ST700 Dash Display System to ignore additional IR
beacons for a period after it senses the first beacon. This ‘lap
masking’ feature prevents multiple triggering within each lap.
2. Attach the wire labelled ‘LAP’ of the harness to the sensor at the 4–
way ‘Sure–Seal’ connector. Take care to assemble this connector in
the correct orientation. Press the two halves of the connector fully
together to ensure a good waterproof seal.
Use a rigid mounting bracket to attach the sensor to the outside of the
vehicle where it can detect the signals from the trackside beacon. Use
the two M18 × 1 mm threaded nuts supplied to secure the sensor.

adjustable for heigh
Trackside I.R. Beacon (optional)
There must be only one Stack trackside beacon used on the track. Do
not place your beacon half way around the track because this might
inconvenience other users of Stack equipment.
If you have fitted the lap timing sensor to your vehicle, you will need to
use the trackside IR beacon to trigger the sensor for each lap.
1. Choose a suitable location for the beacon:
❑ Install the beacon as close as possible to the start/finish line, and
at least 4 metres (12 feet) from other types of beacon.
18
Page 23
ST700 Dash Display System Installation
❑ Set the height of the beacon to be level with the lap timing sen-
sor on your vehicle. Set the beacon level so that it emits a horizontal beam.
❑ Choose a position for the beacon between 2 and 30 metres (6 to
95 feet) from the vehicle as it passes within each lap.
❑ Avoid locating the beacon where the sun is directly behind it.
This is because the lap timing sensor will be unable to distinguish the signal from the beacon against the intense infrared
background signal from the sun.
❑ If you intend to use the beacon for extended periods in very hot,
sunny conditions, protect it from direct sunlight.
❑ Protect both transmitter lenses of the beacon from water spray.
During wet conditions, fit a protective peak over the beacon. Do
not cover the beacon, for example using a plastic bag.
2. You must supply the beacon with power from a convenient 12V DC
source. A sealed lead–acid battery with a rating of at least 2.5 Ah is
ideal for this purpose. From a fully charged condition, such a battery will provide continuous operation for approximately 15 hours.
Operation of the trackside beacon is simple:
1. The beacon begins to operate as soon as you connect a suitable DC
supply.
2. There is a two–colour status LED on the beacon:
© Stack
19
Page 24
Installation ST700 Dash Display System
❑ The LED shows green —Battery voltage is adequate for normal
operation.
❑ The LED shows red— The battery voltage is too low. Fit a fully
charged battery.
❑ The LED is off— The battery is discharged or disconnected.
Manual Lap Timing (optional)
Optionally, instead of the automatic infrared timing described above,
the ST700 Dash Display System can accept lap timing triggers from a
‘Lap Timer’ button located at a convenient position for the driver to operate. Instead of the IR sensor, the cable from the Lap Timer button connects to the LAP input as shown in Figure 3. To fit the manual lap timing
option you will require the switch (ST517) and the wiring harness
(ST918037).
With the manual lap timing option fitted, the driver must press the Lap
Timer button as the vehicle crosses the start line.
Because manual lap timing requires a positive action from the driver,
it is less accurate than the automatic lap timing option by IR sensor
already described. Furthermore, because split timing also comes directly from the lap timing input, any errors in the lap timing will degrade the accuracy of split times. For these reasons, Stack does not
recommend the use of manual lap timing.

ST700 Dash Display System Installation
Wheel Speed Sensor
Figure 9: Wheel speed sensor
The Stack ST670 wheel speed sensor generates an electrical pulse for the ST700 Dash
Display System whenever a ferrous target,
such as a wheel bolt, passes close to its end.
You must install the sensor so that it detects
the wheel turning by a sequence of such targets.
You may also use the ST492 pulse amplifier
to read signals (pulses) from an existing gearbox sensor. Refer to the separate instruction manual supplied by Stack for details of this module.
Once you have installed the wheel speed sensor successfully, the ST700
Dash Display System uses the pulses to measure the vehicle speed. You
must set-up the ST700 Dash Display System correctly to use this information.
1. Select a suitable and convenient location for the sensor. For each
wheel rotation, the sensor must detect at least one ferrous target
(for example, a driveshaft bolt). Note that the sensor will not detect
items such as alloy wheel spokes or other non–ferrous objects and
you should not try to use these as targets.
© Stack
21
Page 26
Installation ST700 Dash Display System
❑ If possible, choose a wheel that experiences negligible wheel
spin, lift or lock–up —for example, an undriven wheel.
❑ Ideally, the targets should be equally spaced around the wheel
so that, with a constant wheel speed, the electrical pulses occur
at regular intervals.
❑ To avoid excessive heating do not install the sensor too close to
the brake disc or calliper.
❑ Position the sensor no closer than 75 mm (3 inches) to ignition
HT leads or sources of intense heat.
2. Make a suitable rigid bracket to support the sensor and attach it to
the vehicle. Fit the sensor to the bracket. Do not over tighten the
sensor—tighten the sensor to 1.2 Nm (12 kgf.cm or 0.9 lbf.ft). Use
fibre washers to insulate the sensor from heat transmitted through
the bracket.
3. Adjust the clearance between the end of the sensor and the ferrous
targets so that the gap is nominally 1.0 mm ± 0.5 mm (0.040 ±0.020
inches). Make certain there are no other objects passing within
4 mm (
3
/16–inch) of the sensor when the wheel rotates.
4. Attach the wire labelled ‘WS’ of the harness to the sensor at the 4–
way ‘Sure–Seal’ connector. Take care to assemble this connector in
the correct orientation. Press the two halves of the connector fully
together to ensure a good waterproof seal.
22
Page 27
ST700 Dash Display System Installation
When you power-on the system, a small light built into the back of the
sensor will light up each time it senses a target. Ensure this light is
visible when you fit the sensor so that you may use it to test the sensor.
The Stack ST669 wheel speed sensor is compatible with the ST700 Dash
Display System and may be used if circumstances do not allow you to
use the ST670. Contact Stack for details.
Pressure Sensor options
You may use pressure sensors to monitor the following conditions:

ST741 ST742 30 psi (2 bar)
ST744 ST745 ST746 150 psi (10 bar)
ST747 (solid state) 150 psi (10 bar)
You may set up the ST700 Dash Display System to display pressure
measurements using PSI or bar, and you may set the system to alert
the driver if the monitored value triggers a pre–set alarm—refer to
page 56 for relevant instructions.
1. Depending on the condition that you wish to monitor on your vehicle, choose a suitable location for the sensor:
❑ Avoid mounting the sensor near sources of intense heat.
❑ Do not mount the sensor closer than 75 mm (3 inches) to ignition
leads, the distributor or the ignition coil.
❑ If possible, avoid mounting the sensor directly on the engine
block because excessive vibration will shorten its life expectancy.
2. Attach the sensor to its appropriate monitor point, if necessary
using suitable pressure hose and fittings.
24
Page 29
ST700 Dash Display System Installation
3. Connect the wiring harness to the sensor at the spade terminals.
Oil pressure switch
You may connect the engine oil pressure switch to the ST700 Dash Display System instead of a Stack pressure sensor. This switch will be ‘open’
when the oil pressure is high and will close when the oil pressure falls
below its operating point and will cause the low oil pressure alarm to
display. To use the engine oil pressure switch as an input to the system,
select the option to use a switch from the Sensor 2 input menu (descr-
ibed on page56). This will then mean that Display Layer 5 (described
on page34) will not be shown.

You may set up the ST700 Dash Display System to display temperature measurements using °C or °F, and you may set the system to alert
the driver if the monitored value triggers a pre–set alarm—refer to
page 56 for relevant instructions.
1. Depending on the condition that you wish to monitor on your vehicle, choose a suitable location for the sensor:
❑ Avoid mounting the sensor near sources of intense heat.
26
Page 31
ST700 Dash Display System Installation
❑ Do not mount the sensor closer than 75 mm (3 inches) to ignition
leads, the distributor or the ignition coil.
❑ Mount the sensor directly in the fluid line so that its end lies in
the middle of the flow of fluid.
2. Attach the sensor to its appropriate monitor point.
3. Connect the wiring harness to the sensor at the spade terminals.
Battery connection
The ST700 Dash Display System accepts power from the vehicle electrical system through the two cables labelled ‘B+’ and ‘B–’ in the wiring
harness.
1. Connect the black ‘B–’ cable from the harness directly to the battery
negative terminal.
2. Connect the red ‘B+’ cable of the harness to a fused supply from
the battery positive terminal. The fuse rating for this line should be
no higher than one amp. This line should become ‘live’ only when
you switch on the vehicle ignition.

Power–on the ST700 Dash Display System
Switch on the vehicle ignition. You should see the following indications
on the ST700 Dash Display System display:
❑ The dial illumination will turn on.
❑ The display backlighting will turn on.
If you have configured the ST700 Dash Display System for a low intensity of backlight, it might be difficult to see the above illumination features.
❑ The four shift lights and the alarm LED should show red briefly and
then go off. Because it is possible to change the intensity of the shift
lights it might be difficult to see these indications on the lowest
intensity setting if the ambient light is very bright.
❑ The tachometer needle will move fully anticlockwise to reset
against its stop. The needle will then settle on zero briefly and then
move to the current engine speed (if the engine is running).
❑ The display will briefly show the version of software in use and will
then show the speed layer.
If none of these indications appears when you power–on the system,

Pop–up Display Layers
The ST700 Dash Display System can supply information to the driver
through several pop–up messages and alarms on the display as shown
in Figure 13. The pop–up messages remain on display for a short, user–
defined period. The alarms remain on display until the alarm condition
disappears or until the driver cancels them.
You may set the time in seconds that the display shows each pop–up
message from zero (meaning that pop–up messages never appear) to 99
seconds (meaning that the pop–up remains on display permanently).
Refer to page 49 for instructions. When a pop–up message appears,
three conditions will cancel it:
1. The pop–up message ‘times out’ at the end of its user–defined pre–
set display period.
2. The ST700 Dash Display System overwrites an existing pop–up
message with a new one that occurs before the ‘time out’ period
elapses for the old message.
3. The driver presses the Driver button to cancel the pop–up message
and return to the normal driver display.
It is important to distinguish between pop–up messages and alarm
messages. Alarm messages will remain on display with the Alarm LED
lit until the alarm is cancelled or until the alarm condition disappears.

Lap and Split Times
The lap timing feature of the ST700 Dash Display System allows you to
measure the following:
❑ Total time to complete each lap
❑ Split times for up to two locations on the track
Figure 14: Lap timing
1. Lap timing starts when the
vehicle passes the trackside
infrared beacon or when the
driver presses the Lap Timer
button (if manual lap timing is
fitted).
2. When the vehicle passes the beacon (or when the driver presses the
Lap Timer button) again, the ST700 Dash Display System will display a pop–up message that shows the total time taken to complete
the lap. At the same time it resets the timer to zero and starts to time
the next lap.
3. The above process repeats for each lap. The ST700 Dash Display
System records the times for the first 75 laps so that you may review
them later. The display will show a warning message when you
switch on the ignition if there is memory space for fewer than 20
laps remaining. It will indicate that the memory is full if there is no
lap memory remaining.

Page 42
Operation ST700 Dash Display System
You may use the Split timing feature to measure, display and record the
time taken to complete sections of the circuit.
The reference point for both split times, S1 and S2, is the point where
Lap timing starts as explained above. This means that, if you move the
beacon, then both split points will move by the same distance also. It is
also important to place the infrared beacon in the same place each time
you visit a track so that the timing results are directly comparable from
one visit to the next.
Note that split timing comes directly from the lap timing feature. Any
errors in lap timing caused by inaccurate manual triggering by the
driver will therefore degrade the split timing accuracy. Split timing errors could also arise from inaccurate wheel speed measurement.
The ST700 Dash Display System allows you to set split distances for S1
and S2 or for S1 by itself if you need only one split time per lap. You may
set the split distances manually, or you may set them automatically as
you drive the vehicle around the track.
After you configure the ST700 Dash Display System with split distances,
it will start to measure distance around the track until it passes the S1
reference point. The display will then show the S1 pop–up message, for
example:
38
This message will remain on display until
one of the three conditions listed on
page 35 cancels it.
Page 43
ST700 Dash Display System Operation
When the ST700 Dash Display System determines that it has travelled
to the second reference point S2, it will show the S2 pop–up message,
for example:
Note that the split times shown by the
pop–up messages are measured from the
start of the lap. In memory review mode,
S1 is the time from the start of the lap to the
first reference point and S2 is the time between the first and the second
reference points.
Manual Split Timing Setup
To set the S1 and S2 split distances manually:
1. Enter the ST700 Dash Display System setup mode by pressing the
rotary control for longer than two seconds.
2. When the display changes to allow memory review or setup, turn
the control clockwise until it shows ‘Performance Timers’.
3. Press the rotary control briefly so that the display shows ‘Split Tim-
ing’.
4. Press the rotary control again to see the current setting for Split 1

ting in larger steps if you hold the Driver button while you make
this adjustment. Release the controls to set the Split 1 distance at the
displayed value, which should be the distance from the lap reference point.
6. Turn the rotary control clockwise by one step to show the current
setting for the Split 2 distance. This must always be equal to or
larger than the setting for Split 1. Press and turn the rotary control
to set the distance from the lap reference point to the second split

8. Press the Driver button as the vehicle passes the second split marker
to set the distance.
This procedure sets both split timing distances automatically. Follow the
instructions on page 39 for setting the split timing distances manually if
you then need to make any adjustments to these distances.
Use the automatic split timing setup feature to measure and set the split
distances when you first visit and use a track. Before you leave the track,
note the split distances and then enter these distances manually during
future visits to the same track. This helps to ensure repeatability from
one visit to the next.
Hillclimb and Sprint Operation
To remove the requirement for a beacon at the start line, your ST700
Dash Display System has an ‘arming’ feature. This allows you to set the
ST700 Dash Display System so that it starts timing from the instant
when the wheels begin to move. Your system must include a functioning wheel speed sensor to use this feature.
Press the Driver button and the Rotary control together from the normal display mode to arm the system. The next time the vehicle starts
moving, the ST700 Dash Display System will record a lap mark. If the
vehicle is already moving, the ST700 Dash Display System will wait for
the speed to be zero.
You will still require a beacon at the finish line to give the end time.

shows a speed range from zero to sixty miles per hour. The display also
shows the most recent time that it took for the vehicle to accelerate
through the stated speed range. This information also appears in a pop–
up message for the driver.
Follow the instructions on page 48 to alter the speed range for the acceleration timer and to enable or disable the pop–up message that shows
this information. You may set a start speed that is higher than the end
speed to use the ST700 Dash Display System as a deceleration timer.
If you press and hold the Driver button, the display shows the shortest
acceleration or deceleration time recorded since you last reset the peak

Channel settings—Press the rotary
control briefly when the display
shows ‘Channel Settings’ to setup the
input channels to the ST700 Dash
Display System. Press and turn the
control to move among the channel
settings sub-menus.
❑ ESPD Input (Engine speed) —
Press the control briefly to see the
current setting for the number of cylinders in the engine. Press and turn
the control to adjust this setting to
match the number of cylinders in the
vehicle’s engine. For two–stroke
engines, set this value to twice the
number of cylinders (for example,
set the value to 4 for a two–cylinder
two–stroke engine, or 6 for a three–
cylinder two–stroke engine—see the
troubleshooting heading on
page 67).
RPM gate—Pop–ups will appear on
an alarm condition only when the
engine speed is above the gate RPM
setting—there will be no alarm pop–

ups when the engine speed is below this setting. This is to prevent
the occurrence of alarm pop–ups when the engine starts and measured conditions such as the oil pressure will be low for a short period. Press and turn the rotary control to adjust the gate RPM setting.
Input level—Press and turn the rotary control to set the system for
a high level or a low level signal for the engine speed input. Your
choice will depend on the source of the signal. Typically the setting
will be ‘high’ if the signal comes from a coil or a magneto, and ‘low’
if it comes from an ECU ‘tacho’ output.
❑ WSPD Input (wheel speed)—Press the control briefly to see the cur-
rent setting for the pulses that the wheel speed sensor detects for
each wheel rotation. Press and turn the rotary control to adjust this
setting, which will depend on the specific installation details. Refer
to page 21 for instructions to install the wheel speed sensor.
Meas units—Press and turn the control to set the ST700 Dash Display System to measure in metric units or in imperial units. This setting affect the measurement units to set the split timing distances
(either in feet or metres) described on page 39, and the wheel diameter setting (in inches or millimetres) described below. It does NOT
affect the units used to display speed or odometer distance, which
depend on the choice you make under ‘Speed & Odo’ described on
page 56.
Wheel circ—Press and turn the rotary control to adjust the setting of
the wheel circumference. The ST700 Dash Display System uses this
54
Page 59
ST700 Dash Display SystemMemory and Setup
measurement, together with the number of pulses, to calculate and
display the vehicle speed and the odometer distance. The accuracy
with which you measure this value has a direct influence on the accuracy of the speed and distance measurements.
Accel limit— Press and turn the rotary control to adjust the acceleration limit setting, which prevents the ST700 Dash Display System responding to apparent extremes of acceleration caused, for example,
by wheel spin. If wheel spin occurs on the wheel that has the wheel
speed sensor, the speed reading from the sensor will step almost instantaneously to a much higher level. This would give errors in the
measurement of distance and split times. To avoid this, the ST700
Dash Display System allows you to set the maximum acceleration so
that it then filters the signal to give more accurate indications of
speed and distance.
Unless you have access to a reliable method for measuring acceleration, you should set this value experimentally. For guidance, an acceleration of 1G applied for 3 seconds will accelerate the vehicle from
zero to 106 km/h or 66 MPH.
Decel limit— This function works in a similar way to the acceleration
limit described above, but applies for deceleration. It prevents the
displayed speed from instantaneously reducing if the wheel that includes the speed sensor locks during heavy braking, for example.

Speed and odo—Press and turn the control to choose between using
MPH and miles or Km/h and kilometres for the displays of speed
and odometer distance.
❑ Sensor Input 1 and Sensor Input 2—The ST700 Dash Display Sys-
tem can display measurements made by up to two Stack sensors fitted to the vehicle. The information from these sensors appears on
one of the display layers (see page 34). Press the rotary control
briefly to set Sensor 1 or Sensor 2 to the correct measurement type.
Refer to Table 2 on page 23 and Table 4 on page 25 respectively for
the compatible types of Stack pressure and temperature sensors.
For each channel, set the measured parameter and then turn the rotary control to select the sensor type fitted and the units that the system will use to display the measurements.
You may also set the alarm type for each measured channel. Select
disabled if you do not wish to set an alarm on a channel.
Set ‘Above’ to display a pop–up alarm when the measured condition
goes above the threshold setting that you define (for example, when
you monitor water temperature).
Set ‘Below’ to display a pop–up alarm when the measured condition
goes below the threshold setting that you define (for example, when
you monitor oil pressure).
Set a threshold value for the alarm setting. The option to set a threshold
will not be available if you have disabled the alarm feature.

Select whether the RPM gate, described on page 53, is enabled or disabled.
❑ Battery Input — Press the rotary control briefly to see the current
setting for the battery alarm. Press and turn the control to set the
battery voltage below which the alarm pop–up will appear. You
may also set the RPM gate for the battery voltage alarm.
❑ Lap Time Input—Press the rotary control briefly to see the current
setting for Lap Masking. Press and turn the control to adjust the setting. You will disable the lap masking feature if you set the value to
zero.
The infrared lap timing system supplied by Stack uses a coded infrared frequency that is common to all Stack lap timing systems. This
feature allows users of Stack systems to share a common beacon at
each circuit, and ensures that the ST700 Dash Display System will
not be triggered by other manufacturers’ timing beacons.
The lap masking feature allows you to make certain that your system
does not pick up signals from incorrectly placed Stack beacons that
could trigger a false lap time. Typically, you should set the lap masking time to 50% of an anticipated lap time.
© Stack

Page 62
Memory and SetupST700 Dash Display System
It is important that you are aware that your beacon can be picked up
by other Stack systems and can affect their lap times if you set up your
beacon mid–session. Therefore, for the convenience and out of respect to other users, you should not set up your beacon when cars are
running. You should also consider cooperating with other users of
Stack systems and use only one beacon at the circuit, although the
different sensor heights on vehicles might require more than one beacon.

Testing ST700 Dash Display System
TESTING
After you have installed and set–up the system as described in this manual, you should test it to make certain all the sensors, displays and alarm
functions work correctly:
1. Switch on the vehicle ignition and check that the ST700 Dash Display System initialises correctly as described on page 31.
2. Start the engine and let it warm at idling speed. Check that the
tachometer display shows the correct reading for the engine idling
speed. If the tachometer shows a value that is completely wrong,
you may have set the engine cylinders incorrectly. Refer to page 53
for instructions to set the number of cylinders.
3. Accelerate to a constant, safe speed, and time the vehicle between
two markers whose separation distance you know. Calculate the
vehicle speed and confirm that it is as shown by the ST700 Dash
Display System. Any difference between the actual vehicle speed
and the displayed value could be caused by one of two factors:
❑ You have set the Wheel Pulses parameter incorrectly. Refer to
page 54 for instructions to set the wheel pulses.
❑ You have measured or set the Wheel Circumference parameter
incorrectly. Refer to page 54 for instructions to set the wheel circumference.

Extra laps displayed. Lap times are too short.
❑ More than one transmitter around the circuit
Remove all but one transmitter from the circuit.
Increase the Lap Masking period.
Display values and messages unclear or unreadable (poor contrast)
❑ Display too hot or too cold
Ensure that the display operates within its specified temperature range
Operating temperature range is –20° C (–4° F) to +70° C (+158° F)
❑ Incorrect contrast setting
Enter the setup mode and re–adjust the display contrast value
Tachometer value too high or too low by a constant %-age amount
❑ System configured with wrong number of engine cylinders
Reconfigure the system to the correct number of cylinders.
❑ The vehicle is using a 2–stroke engine
Set the number of cylinders to twice the actual number.
For example, a 2–cylinder 2–stroke engine requires the number of
cylinders to be set to 4.
❑ Ignition system pulses per revolution not the same as the number of
cylinders
© Stack
67
Page 72
Maintenance ST700 Dash Display System
Reconfigure the system to the correct number of pulses per revolution.
Ignition systems may use multiple coils where each additional coil
gives proportionately fewer pulses per revolution.
Tachometer reading erratic, pointer jumps high or low
❑ Incorrect wiring
Reconnect the tachometer as specified in this manual
❑ Signal not intended to drive a Tachometer
Check for a more suitable connection point.
Use the ECU tachometer output signal in preference to the coil negative.
No Tachometer reading
❑ Incorrect wiring
Check the connection of the engine speed wire to the ignition system (or sensor, if used)
See the instructions supplied in this manual. If connected directly to
the coil, check that it is to the switched low tension side (usually the
negative side).
❑ Signal not suitable to drive a Tachometer
Signal from ignition or ECU is only 5V. Select the low engine speed threshold in the menu structure—see page 54.
68
Page 73
ST700 Dash Display System Maintenance
Check for a more suitable connection point, such as the coil negative
signal.
❑ ECU or ignition system output requires a ‘pull up’ resistor to be fit-
ted
Fit a 1k0 ohm (1000 ohms) resistor from the ECU/ignition to Tacho lead, to
Battery positive B+
Important: Check with the ECU/Ignition system manufacturer that
this will NOT damage their system.
Displayed speed value too high or too low by a constant %-age
amount.
❑ System configured with wrong number of targets per wheel revolu-
tion
Reconfigure the system with correct values.
❑ System configured with the wrong wheel circumference
Reconfigure the system with correct values.
Typical wheel circumference is 1800mm (70 inches) for a car or
900mm (35 inches) for a kart
No speed reading. Speed reading erratic, value jumps high or low.
❑ Faulty sensor and/or wiring
Check the sensor indicator for correct operation.
© Stack
69
Page 74
Maintenance ST700 Dash Display System
Rotate the wheel by hand and check that the sensor indicator lights
up as each target passes the sensor
❑ Incorrect sensor gap (too far or too close)
Check that the gap is approximately 1mm ± 0.5mm.
❑ Sensor and targets moving apart
Fabricate a more rigid sensor bracket
Speed reading dies after a short time
❑ Ambient temperature is too high
Shield the sensor from radiated heat from brakes and bearings. Use fibre
washers to insulate the sensor from conducted heat. Duct cooling air around
the sensor.
Maximum temperature for correct operation of the wheel speed sensor is +80°C (175°F)
Display works OK until engine starts then Display freezes or resets
continuously. Display recovers once the engine stops.
❑ Interference from ignition system and HT leads
Fit suppressed (Silicon) HT Leads. Fit a suppression capacitor (2.2uF) between the coil (battery connection) and chassis. Check the capacitor on the
distributor points system—fit a new capacitor if necessary.
Use ‘Helical’ suppressed leads in extreme cases.
70
Page 75
ST700 Dash Display System Maintenance
❑ ST700 Dash Display System wiring is too close to the HT leads and/
or injector leads, or the HT leads are tied to isolated metal work to
which the system wiring is also tied.
Run wiring away from HT leads and injector leads
Recommended minimum spacing is 75mm (3.0 inches)
Needle dances up and down, lap times appear and speed is shown
when the vehicle is stationary.
❑ The ST700 Dash Display System is in Demonstration Mode.
Set the correct number of cylinders, by following the instructions on
page 53, to turn off Demonstration Mode.
You can restore the ST700 Dash Display System to its factory settings
by pressing the Driver button and the Rotary control together, and
then switching on the ignition. This also clears the lap and split timings, and resets all the peak readings.
After you restore the factory settings, the Demonstration Mode will be
activated. To turn off the Demonstration Mode, set the correct number
of cylinders as instructed on page 53.
