FD-4 User Manual
Contents
1. the cable is not connect to each other no short circuit especially E and E otherwise it will damage the transmitter 3 Except the adjustable electronic potentiometer please do not change other organ of the transmitter 4 The transmitter should be installed in the place without any surge impact Installation must be stable and try to avoid bump shouldn t have strong corrosive gas around it 7 Judge troubles and trouble shooting Please make sure the right connection and debugging according to the operating instruction Please reference graph 1 If the users judge there is something wrong with the transmitter s organ or the circuit board has been damaged please send the product back for repairing 8 Notice 1 Generally the transmitter is matched with our strain type load cells so there is a fixed inner connection and every potentiometer is sealed If the user wants to connect or debug please let us know usually do not open the transmitter 2 The transmitter is not suitable for using in the insulation environment or powerful humid environment 3 If the users want to connect the wire or debug by themselves please reference the operating instruction 4 The transmitter that is connected and debugged by our company we can repair it when the transmitter has troubles under normal use in one year 5 If you have some special requirement please contact with us directly Trouble Trouble shooting NO Output 1 Chec2. FD 4 Transmitter User s Manual XIAMEN ELANE ELECTRONIC CO LTD Dear users Thank you for buying our product FD 4 transmitter please read this manual carefully before use and you are welcomed to contact with our technician when you meet some problems Summary FD 4 is designed to match with our strain type load cells can be widely used in the non electrical measurement situations that use strain type load cells High precision stable performance and easy use is our product characteristics 1 Suitable for strain type load cells 2 Can connect 1 4 load cells directly 3 Can protect reverse connect of voltage and protect output 4 Two options Electrical current voltage output 5 Multiple options of output capacity Please indicate the type current or voltage transmitter and the output capacity when you order our transmitters 1 Specifications 1 Power supply DC15V 24V 150mA MAX 2 Output current 4 20mA or 0 10mA Voltage 0 5V or 1 5V 3 Accuracy Excelled 0 1 FS 4 The total sensitivity of connecting sensors 1 1mV V 2 2mV V 5 Resistance of load lt 3509 current output gt 250 2 voltage output 6 Operating temperature 20 C 85 C 7 Protection class IP65 2 Electronic principle figure Stable voltage switch TI GVOT UV ous 1110119 019Z 1sn py GND 3 Connection and potentiometer distribution Figure XS1 XS4 sensor end the definition of each connection term

4. k power supply 2 Check voltage of E and E if power supply is good but no excitation voltage please send back to our company 3 If the load cell has excitation voltage but no output signal please change load cell 4 For the current transmitter audion damage will also cause no output please send back to company No 1 Check voltage of E and E or S and S if load cell has excitation voltage Reaction on please change load cell 2 Check if sensitive output under real load is in the range load if not please change load cell 3 Calculating amplifier or V I or tracker damaged please send back to the company Output 1 Check if the load cell parameter changed if changed please readjust the Abnormity transmitter 2 Leach capacitor damaged or voltage switch circuit trouble please send back to the company 3 If load cell is abnormal please change load cell
5. n link the power and turn it on A balanced adjustment 1 Load each sensor separately and record the current voltage output of each sensor under the load condition 2 Count the average output and use these data as a benchmark when adjust 3 Load on each sensor again separately adjust the balanced potentiometer RP1 RP2 and make sure the output of sensor is the same with the benchmark 4 Repeat the step 1 3 mentioned above there are some influence between each other when adjust the potentiometer until the output of sensor is the same the benchmark when load B Output adjustment after balanced adjustment 1 When the system is unloaded adjust the preliminary output and the potentiometer RP6 and make the output reached the preliminary output 2 When the system is fully loaded adjust the full output of potentiometer RP5 make the output reached the full scale output 3 If the output do not reached the preliminary output after the system is unloaded adjust full scale load may affect the preliminary output repeat step 1 2 mentioned above until the full scale output and the preliminary output reach the standard 6 Installations and Usage 1 Connect strictly as per the definitions especially pay attention to distinguishing transducers end and output end wrong connection will result in no output and damage 2 If there are any redundant cable conductors which connect to the sensor you must tie up the wire and make sure
