2. Notes

  • The technicians who install sensor, must be graduated from college of mechanic or electric.
  • The mechanical installation staff (drill, cut, grind, etc.) must have skills in mechanical engineering.
  • The electrical installation staff (connect, etc.) must have skills in electrical engineering.
  • The technician must be trained before using.

3. Safety

  • CAP10G is intended to use with Diesel Oil, Vegetable Oil.
  • CAP10G must not be used with other flammable fluid such as Gasoline, Alcohol, Ethanol, Acetone, Toluene or other solvents.
  • Be careful while drilling, cutting, grinding, etc. The fuel tank or other flammable fluid.
  • Daviteq is not responsible for compensation in case of explosion to bodily injury or property damage.

4. Note Before Installation

  • Read specifications thoroughly and make sure that its output are suitable to reading devices.
  • Power supply must be in the permitted range.
  • Do not take out the label and take off the lid as this will lead to the instability of the sensor and manufacturer could deny warranty. (except cutting of sensor length within the allowed range).
  • Make sure all the necessary tools are ready before the installation.
  • CAP10G be equipped with screws. We advise customers should use stainless steel rivets to fasten the plastic flange onto tank for all type of tanks and only using screws for the thick and hard ones.

8. Sensor Installation Guidance

Step Discription
Note
1 Remove fuel: Remove all fuel from the tank.

Some tank have been welded with oil filter and have float level sensor installed, so it is necessary to take out the float level sensor before removing the fuel.

2

Clean the tank

Must clean the tank thoroughly.

3

Central hole locating: The hole will be in the center of tank's up-per side or closest to center.

This is an important step as it will directly affect the stability of the fuel level data.

4

Drilling the central hole:

  • After determining the center of the oil tank, we clean the surface and use a 38 mm drill to make a hole on the oil tank.
  • Remove any burrs from the drilled hole by a file.
Before drilling, it is vital to check whether the hole is affected by the internal metal frame or obstacles at the bottom the tank.

5

Flange installation:

  • Place the 4 mm rubber gasket at the center of the tank's upper side.
  • Place the plastic flange onto the rubber gasket (4 mm).
  • Mark 4 points at the bolt hole.
  • Use screws /rivets to fasten the 4 mm rubber gasket and the plastic flange onto tank.
  • Only using screws for the thick and hard tanks.
  • Unplug the screw/ rivet symmetrically.

6

Sensor cutting:

After flange installation, we determine the length of the sensor to be installed as picture below:

CAP10CN-H7.png

C = L+20+20-(H+14) => C = L+26-H (mm)

C: Length to be cut.

L: Original length of the sensor.

H: Height of the tank.

 

*Example:

CAP10G-H9.png

Sensor length is L = 2000, H = 1700 mm => C = 326 mm => Cut the sensor pipe length of 326 mm.

7

Calibration:

  • After cutting, make sure the sensor tube is clean.
  • Re-plug the Filter footer and tighten the screw.
  • Turn on the sensor in at least 30 seconds in order for the sensor to automatically recognize its new length.

8

Final:

  • Place the O-ring on the top of the threads, ensure that it can touch the aluminum housing of the sensor  (as below picture):

CAP10G-H10.png

  • Install sensor into the threads of flange and turn it in clockwise direction.
  • Using the O-ring enables to rotate the sensor within 180 degrees from final tighten position and assuring that the oil will be not spilled (as below picture):

CAP10G-H11.png

  • Use the 2mm Allen key to lock the hex bolt to protect the sensor rotate backwards.
  • Connect the sensor with the cable.
  • Use sensor head seal to cover the sensor and then use plastic and then use plastic twister seal to lock the head seal and connector seal to protect the sensor.

9. Disassembly Guidance

Please follow the below steps: Note

Step 1: Remove the cover

Step 2: Remove the terminal connector

Step 3: Use the 2 mm Allen key to unlock the hex bolt

Step 4: Turn the sensor in counter-clockwise direction

  • Do not hold the male connector to rotate sensor directly, that can make the male connector broken.
  • Do not use locking pliers, pipe wrenches, etc. to twist the sensor as this cause damages the structure of the sensor such as cast aluminium housing, label, signal cables (connector), circuit board, ect. and it will not be covered under warranty.

10. Wiring

CAP10G-H7.png

CAP10G-H12.png

10.1 Follow Labels in Wires:

Each cable includes wires which are marked labels according to types of connection. (user should not cut these labels before installation to avoid confusing)

10.2 Follow Wire Colors:

  • White: PWR+(8...50VDC)
  • Blue: PWR-(OVDC)
  • Black: Resistive Output (240.33 Ohm)

Recommend to use 24VDC power.

The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid high temperature areas.

11. Periodic Cleaning Guidance

  1. Periodically clean the oil tank 2, 3 or 6 months depending on usage and contamination.
  2. Periodically clean the sensor and filter footer 2, 3 or 6 months by:
    • Cover a sensor's vent before using the air sprayer for another.
    • Remove and clean the filter footer.

12. Troubleshooting

No. Phenomena Reasons Solutions
1


No output

Sensor's powering wire is damaged

Check out on the sensor's powering wire

Overpowering has burnt the signal cable and circuit board

Send  to manufacturer

Being tampered

Check the seal again before sending back to manufacturer
2 Signal interference Sensor was installed too far from  central hole of tank Install sensor as closest as possible to the central hole of tank (the common point of 02 diagonals)
3


Unstable output with many significant strikes

Accesories burnt or there is liquid inside of board

Send to manufacturer

 

Connection to power supply is loose

Check the connection wire

There are impurities in oil tank, such as: boil, mud, sand, water,...

Clean tank as well as sensor
