2.Instructions

2.1 definition of the output line

Interface output line use 6 core cable, connecting definition:

0~5V output [CA-201A]:

Black line connect ground wire

Red line connect positive power

White line 0~5V voltage signal output,connect voltage signal wire

Yellow line empty fuel tank use only

Green line full fuel tank use only


2.2 Calibration

self-calibration: put the sensor slowly into the The tested medium while power on, let the liquid get into the feed inlet slowly ,stoping when the liquid is overflew the vent hole of the sensor. and this operation accomplish the calibration of the sensor . In order to prevent the failure of the calibration process , please do this process for at least 2 times .( notice:This way is under the condition of powering on , outage restart will restore the factory Settings.In the condition of empty fuel tank,refueling to full, the sensor itself are also able to complete the self-calibration )

Manual calibration: at the time of empty fuel tank, put the yellow line short circuit with the ground wire( black line) , and then power on the sensor, operating for 60s or longer, after that , disconnect the back ground wire and the yellow line , and this operation could accomplish the calibration ( notice: Sensor already setted to 0 # diesel prior to shipment ,without Special Circumstances)

Installation position should be placed as near as possible to the center of the fuel tank, in order to reduce the influence of the oil level of tilt and the oil level of volatility while on the hill.


3.Notice

7. Do not remove sensors or damage it maliciously, or we do not guarantee it.

8.General factory accessories include Flange, rubber blanket, O-Rings, booklet of instruction, certificate of conformity. If you have special needs, please tell us in advance.

9.Guarantee period of the sensor is one year. All accessories including rubber blanket, O-Rings, are beyond the scope of “ threeguarantees ”.


Symptom of failure

1No-output /communication error

2The output value unchanged

3Measurement error of output value

4Output value floats up or down


cause analysis

4 oil level flow

service voltage abnormal

external interference

Sensor fault

Exclusion and solutions

check the oil leve is stable → check the service is normal and functional →whether external have interference →execute the 2.2.2 process→then it should be the sensor fault


remark

1 4~20mA output supply voltage DC20~28V,current is 4~20mA except communication output

2Check the tank oil level is float or not,if become regular after recharge,check the interference and the power

4 it usually occur on 0~5V signal
