Pulse speed calibration

• Before pulse speed calibration, please make sure:

1. Speed limiter is working normally.
2. Pulse wire is connected right to vehicle speed signal wire.

• Calibration steps:

1. Park vehicle on a flat road. Send command: PCS,1; . There is no reply to this command but device shall make a beep sound.
2. Drive vehicle at stable 40KM/H for 15 seconds, then press SOS button for 3 seconds. Speed limiter shall make a fast sound.

• How to check if calibration succeed or not?
  After calibration is done, disconnect vehicle GPS antenna, drive vehicle and check on platform if there is speed data. If there is speed data, it means calibration is okay.
  For same type vehicle, the pulse coefficient (PPK) is same. Use PC config too to read it or check online at the Extend State, after the first vehicle is calibrated. Then use PC tool or SMS command to config the device pulse coefficient for other devices.

External Optional accessory connection

1. Mechanical actuator: Limiter NO ( Yellow) connect with actuator Green signal wire.

   • Actuator has 3 wires. Red for battery Positive+, Yellow for Ground. Green is signal wire.
   • Connect limiter Yellow wire to actuator Green wire, the steel rope shall reach out around 5CM, disconnect device Yellow wire, the steel rope shall pull back around 5CM.
   • When speed reaches, device Yellow wire has no power, then actuator pull back the steel rope.

2. Solenoid valve (12V or 24V): Limiter NO ( Yellow) connect with solenoid valve PIN1.

   • Take 24V solenoid valve as an example: Please connect limiter Yellow wire to PIN1, connect PIN2 to battery Ground. PIN3 No need connection. At safe driving speed, fuel flows through the valve. If driving speed reaches speed limit, valve shall stop fuel flow so as to reduce speed. When speed is below speed limit, valve shall enable fuel flow again.

3. Pedal controller: Connect limiter NC (Green) wire with controller Red wire. Controller black wire connect to Ground. (NOTICE: Please follow below diagram ONLY.)

Pedal controller installation:

1. Find the vehicle pedal harness, it is composed of 6 wires, 2 wire is the signal wires, 2 wire is power wire, 2 wire is ground wire. Start the vehicle, step on the pedal, make vehicle at idle state, voltage at signal wire shall change.

2. Cut off the 2 signal wires, and then connect respectively the pedal controller wire. Please refer below picture. Red wire connect with speed limiter NC (Green) wire

Geo-fence based Speed Limit

• In order to limit vehicle speed per different areas, user can draw fence (Round,
• Rectangle, or Polygon) at the web monitoring software so as to limit vehicle speed at different valve per real environment.
• For example, at urban area, set speed limit at 60KM/H; at suburb area, set speed limit at 80KM/H.
• The fence must be large enough to enable trigger time, otherwise fence cannot work.
  **New software is upgraded on 10th December 16, 2020

**

Geo-fence types:

1. Round
2. Rectangle
3. Polygon

Geo-Fence alarm types:

1. Moving-in fence
2. Moving-out fence
3. In/out Fence

Speed Limit setup:

1. Moving-in fence, Fill ONLY In-fence speed limit
2. Moving-out fence, Fill ONLY Out-fence speed limit
3. In/out Fence, Fill both In-fence and Out-fence speed limit.

Steps:

1. Login web monitoring center with provided account
2. Go to Geo-Fence
3. Create required fences and setup In-Fence or Out-Fence speed limit value
4. Assign device to the created Geo-fences

PC config tool

By connection device to computer, user can setup and read device details as below.
Limiter serial is device ID, please do not change it.

Usage:

1. Connect device with to computer, choose the right COM (here is COM3)
2. Fill in data except Limiter serial
3. Click Setup to config
4. Click Read to read config data

USB Downloading

Insert USB disk for data download. Device makes beep sound after inserting, long beep once all data is downloaded. USB downloading shall download the last 72 hrs driving data with Over speed data included at the end.

Bluetooth Printing (Optional)

1. Turn on Bluetooth printer. Printer will make 2 beep sound.
2. Connect the SOS button to device
3. Press the button for 3 seconds, device shall make a beep sound
4. Wait for few seconds, the printer shall start print data. Please wait till all data is printed.
   Device shall make a long sound once all data is printed.

Web and APP usage

Fuel monitoring calibration

Connection:

1. Find sensor voltage output signal wire
2. Find limiter Grey wire.
3. Connect them together.
4. Power up respectively GPS speed limiter and Fuel sensor.
   • GPS Speed Limiter uses analog input to read data from fuel sensors, no matter it is capacitance fuel sensor or ultrasonic fuel sensor. The sensor voltage output ranges from 0V to 5V, corresponding to tank fuel amount from 0L to Full.

  * Each time, the fuel amount (This data is called Car display Fuel Level) changes, the device upload data on the web tracking software shall change as well. This data is called Device upload Fuel Level.

Calibration:

• In theory, the more calibration is done, the more accurate the fuel monitoring will be.
• Here we advise at least 5 calibration. Below device upload data is example only.
  Tank Fuel Percent

(Car display Fuel Level)

| Device upload data

(Device upload Fuel Level)

---|---
0| 0
25%| 13
50%| 25
75%| 38
100%| 50

• In the above diagram, we empty the tank, then add fuel gradually every 25% of total tank volume. And we have 5 pair of data, which are to be filled in below picture.

• Login your web tracking account, select the device:

  1. Config command
  2. Fuel calibration
  3. Fill in the 5 pairs Car display Fuel Level and Device upload Fuel Level
  4. After filling each pair of data, you need click Add
  5. Fuel tank volume, fill in the tank total volume
  6. Click OK to store the calibration.

Speed Limit and Pulse Speed Value Display on Web

Per FTA requirements, speed limiter monitoring web should display Pulse Speed Value and Speed Limit at Extend state as below
