    ST700 Dash Display System Installation 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.

  • Page 20: Lap Timing Sensor Option

    Lap Timing Sensor option The lap-timing sensor triggers the ST700 Dash Display System automat- ically 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:...
  • Page 21 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.

  • Page 22: Trackside I.r. Beacon (Optional)

    Infrared beacon adjustable for height 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.
  • 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 hori- zontal 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.

  • Page 24: Manual Lap Timing (Optional)

    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 op- erate. Instead of the IR sensor, the cable from the Lap Timer button con- nects to the LAP input as shown in Figure 3.

  • Page 25: Wheel Speed Sensor

    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 infor- mation. 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).
  • 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.

  • Page 27: Pressure Sensor Options

    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.
  • Page 28 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.

  • Page 31: Battery Connection

    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 electri- cal system through the two cables labelled ‘B+’ and ‘B–’ in the wiring harness.

  • 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 re- spect to other users, you should not set up your beacon when cars are running.
