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: 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: 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): 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): 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.

7	Calibration: After cutting, make sure the sensor tube is clean. Re-plug the Filter footer and tighten the screw.   PLEASE FOLLOW THESE STEPS IN ORDER: GET ZERO (4mA): After cutting, clean the probe, put the probe in the media at expected level near the bottom or leave the probe at dry condition, press CALIB button in 0.2 - 3 seconds, the LED will always ON in this press time.=> ZERO is achieved, output current = 4mA. GET SPAN (20mA): Put the probe in the media to the expected upper level then press CALIB button in 3-6 seconds, the LED will ON then OFF.=> SPAN is achieved, output current = 20mA. In 30 seconds without pressing the CALIB button, the sensor will turn back to OPERATION mode.
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): Install sensor into the threads of flange and turn it in clockwise direction.

11.2 Calibration 4-20mA

PulseCAP10 with 4-20mA Output has an advanced feature is Field Calibration. Field Calibration allows customers to calibrate the sensor after cutting. It will works with many non-conductive media such as Vegetable Oil, Non-standard Diesel, Light Fuel Oil... To enter Calibration Mode: press the CALIB button on top housing 3 times, time interval between press not greater than 1.5 seconds. LED will blinked at 5Hz in Calibration mode.

It is recommended to use a PVC plastic tube and oil to calibrate the 4-20mA before inserting into the oil tank

PLEASE FOLLOW THESE STEPS IN ORDER:

GET ZERO (4mA): After cutting, clean the probe, put the probe in the media at expected level near the bottom or leave the probe at dry condition, press CALIB button in 0.2 - 3 seconds, the LED will always ON in this press time.=> ZERO is achieved, output current = 4mA.

GET SPAN (20mA): Put the probe in the media to the expected upper level then press CALIB button in 3-6 seconds, the LED will ON then OFF.=> SPAN is achieved, output current = 20mA. In 30 seconds without pressing the CALIB button, the sensor will turn back to OPERATION mode.

12. Connect with LFC128-2

13. 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.

14. Troubleshooting

No.	Phenomena	Reasons	Solutions
1	Modbus failed to communicate	Connection or configuration error	Check the connection. Check the Modbus configuration: Address, Baud Rate, Parity.
2	Timeout Modbus	Noise appears on the line	Configure Baudrate 9600. Use twisted pair cable with anti-jamming protection (if necessary to extend the signal cable) The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid high temperature areas.

PROTOCOL SERIAL FOR CAP10 V1.5

PROTOCOL SERIAL FOR CAP10 V1.5

 

PROTOCOL: RS232, 9600, 8, 1, N

CONTINUOUS STRING WILL BE TRANSMITTED AS BELOW:

AAAA,BBBB,CCC,WW,ZZ,UU,DDDDDDDDDDDDDDDDDDDD,SSSSS,MM,NN

AAAA	Filtered output, Part per thousand
BBBB	Non-filtered output, Part per thousand
CCC	Electronics Temperature, deg C
WW	Filter weight w1
ZZ	Filter weight w2
UU	Filter bypass
DDDDDDDDDDDDDDDDDDDD	Diagnostic Code
SSSSS	Serial number of sensor
MM	Error code
NN	Checksum

Example for Calculation of Check sum

string = '0000,0000,024,30,05,02,09230006809050006616,00300,00,1C’,0xD,0xA

Number of Data byte: 53 bytes

Example : 0000,0000,024,30,05,02,09230006809050006616,00300,00,

CRC8     :     2 byte

Ending  :     2 byte       EX : 0xD,0xA

CRC8 : checksum of 53 byte data 0000,0000,024,30,05,02,09230006809050006616,00300,00,

CRC8 cal:

CRC8= data1+data2+.. +data51

CRC8=CRC8 mod 255

CRC8L =CRC8 & 0xF

If (CRC8L <10)      CRC8L = CRC8L +’0’  rang [‘0’-‘9’]

Else                       CRC8L = CRC8L +65   rang [‘A’-‘F’]

CRC8H=(CRC8 & 0xF0) /16

If (CRC8H <10)      CRC8H= CRC8H +’0’   rang [‘0’-‘9’]

Else                        CRC8H = CRC8H +65   rang [‘A’-‘F’]

EX :

string = ‘0000,0000,024,30,05,02,09230006809050006616,00300,00,1C’,0xD,0xA

CRC8=’0’+’0’+..+’0’+’,’=0x30+0x30+…+0x30+0x2C=0x0A1C

CRC8H=’1’, CRC8L=’C’

EX:

string  =  ‘0567D2’,0xD,0xA

Data = ‘0567’

CRC8=’0’+’5’+’6’+’7’=0x30+0x35+0x36+0x37=0xD2
