Height sensor
Notes: For the installation of the height sensor, you need to watch the movement of the suspension under the car, this process should be completed with the help of jack. Fig.6-1 shows the distance of some points of the suspension arm when it moves up and down. The distance can't be too near or far away from the point O. "A" is very near rotation point O, then it almost has no space to move, "B" is far away from point O, it has enough space to move, but it may damage height sensor or linkage(Fig.6-2). 1.Find a desirable mounting point (name as"X") at the suspension, use it as the datumpoint in the following measurement(Fig.6-3). 2.Draw a comma at a corresponding place of the suspension arm under X(It will be the mounting location for the bolt of the linkage). 3.Rise the vehicle to the highest position, name the distance from X to the comma as A(Fig.6-4). 4.Lower the car to the lowest point, name the distance from X to the comma as B(Fig.6-5).The distance of the sensor movement is A minus B(Fig.6-5). 6.Install
A B 0 Fig.(6-1) Fig.(6-2) Keep proper drip loops and use proper bend radius for wire bundles HEAD 120mm 04
5.If the movement distance is shorter than 120mm,then move the two points (X and the comma) a little far away from the rotation point of the suspension arm, repeat step 1, step 2 and step 3. Ifthe movement distance is longer than 120mm, then move the two points a little nearer to the rotation point of suspension arm, repeat step 1,step 2 and step 3. It' s hard to adjust the distance to 120mm accuratly, keep the distance below 120mm,not above 120mm(Fig.6-6). 6.Regulate the mounting hole, drill or weld a hole for mounting bolt of the linkage at appropriate place(Fig.6-7). 7.Mount one end of the linkage to the suspension arm with a bolt, move the suspension arm to the middle place between the highest and lowest position, adjust the swing arm of height sensor to close zero angle with the centerline of sensor body, choose a appropriate connecting location with another end of the linkage, cut the linkage appropriatly, connect it to the mounting hole of the swing arm(Fig.6-8).05 suspensin chassis suspension arm A Fig.(6-5)Fig.(6-4)Fig.(6-3) B
8.Connect the swing arm and the linkage with a bolt, and then find a mounting ocation, draw the installation profile of the sensor, drill two holes to mount it (Fig.6-9). 9.Lower your vehicle to the lowest position(Fig.6-10) and rise it to the highest position(Fig.6-11). Check whether the height sensor is in the appropriate location, if not, adjust the linkage to get the appropriate location(Fig.6-9). 10.Confirm the number of each height sensors according to the annexed figure I(the diagram of connecting wiring), connect the corresponding height sensors(Fig.6-12).

Notes:Connect the cable harness according to mark correctly. Press hard until you hear click of lock. Mind the sharp-edged metal,the cable harness may be insulated,use U-shaped wrapping strips to protect it. There are two sets of relay control which can be used at the same time. If you just need one, connect either of them. 1.Connect ECU with the main harness, then distribute each branch to corresponding component according to the diagram of connecting cable(Fig.10-1). 2.Connect air compressors with power cords: connect the fuse end of the red principal line with the positive pole of vehicle battery and connect the other end with relay terminal which marked "B+". 3.Connect the cable which marked "ACC+" with vehicle ignition power. 4.Connect the cable which marked "Valve#1" and "Valve#2" with the manifold. 5.Connect the cable which marked "Relay Control 1" and "Relay Control 2" with "Relay control" of the relays. 6.Connect the cable which marked "Rotary Position Sensor 1&2" with the corresponding cable joint which marked "Rotary Position Sensor 1&2"(1 means left rear, 2 means right rear). 7.Connect the cable which marked "Rotary Position Sensor 3&4" with the corresponding cable joint which marked "Rotary Position Sensor 3&4"(3 means left front, 4 means right front). 8.Connect all the cables which marked "B-" to the ground(car body metal). 9.Fasten GPS antenna and ECU,then fasten the antenna in a position which receives GPS signal well. 7.Install cable harness 07
9.Installation Software H1 User H1 Setup 10. Test and adjust Notes: The engineer version of H1 APP is appropriate for the people who install and debug the H1 air suspension system. The user version of H1 APP is appropriate for end users. Download H1 APP in Apple Store. The H1 air suspension system must be setup and debugged by the engineer version of H1 APP first, otherwise the remote controller or the user version of H1 APP can't control normally. Notes: Connect the air line with suitable components correctly. Mind the bend angle of the air line which may cause jam or damage to the air line. Use U-shaped wrapping strips to protect the air line against sharp edges of other parts. 1.Install air line according to the diagram of connecting air line(Fig.10-2). 2.The ports of the manifold connect as follows: "TANK" connects the tank, "EXT" connects silencers, "1"connects left-rear air bag, "2" connects right-rear air bag, "3" connects left-front air bag, "4" connects right-front air bag. 8.Install Air Line Notes: Use the engineer version of H1 APP to test and adjust. Make sure there is no any obstacles above and under the vehicle before "FULL-AUTOMATIC ADJUSTMEN" start. 1.Check the connection of air line and connectors of each parts, start the car and check whether the air compressors work, whether there is any leakage, whether the system is under control. 2.Turn the operating device WIFI on,connect HF-LPB100 and enter the password(The password consists numbers and uppercase characters, which is under the bar code of the packaging box or ECU housing label.) 02

the Max.Pressure of the tank, press "SAVE" after inputting the value(145psi is suggested,the Max. Pressure can' t be above 200psi)
the Min.Pressure of the tank, press "SAVE" after inputting the value.(The value must be below the Max.Pressure).
"Height hysteresis" ,press "SAVE" after inputting value. "Height hysteresis" means the control system adjusts the car height within the range of error when the height value of car minus the system setting value ,which is above height hysteresis. 4% is suggested during the installation; 8% is suggested after installation.Then give the users to use(Different kinds of cars may have different installations).
buttons in the middle are adjustment functions.
ADJUSTMEN": the control system adjust full automatically. Before start, make sure there is no any obsta cles above and under the vehicle. During the adjustment, the vehicle will be risen to the highest position and lowered to the lowest position, press "STOP" if any abnormalities occur. After the process, the app will popup the result, if succeed, the vehicle will be adjust to COMFORT mode, if not, there are problems with the hardware check the simple troubleshooting.

Notes:
Cut all air line ends as squarely and as smooth as possible. Bad cuts may cause leakages. Auto water trap must be installed vertically. Wrong positions may cause failures. It's necessary to install a check valve between auto water trap and the tank.Connect two wires of auto water trap with air compressor wires one-to-one. The check valve is installed at the air compressor air line when you get it.
Use thread sealing glue or Teflon tape moderately. Too much of them may cause damage or jam.
