Please make sure the product and the device which connect with RS-485 are on common ground, avoid damaged product.

Installation

The following table specifies the required straight lengths of the pipe sections depending on pipe diameter in case of different disturbances.

<90°) >

Type| Drawing| Upstream straight pipe || Downstream straight pipe
---|---|---|---
Light bend (<90°)| | 10xD| 10xD
T-junction| | 15xD| 10xD
Two 90° bends n one plane| | 20xD| 5xD
Two 90° bends with 3- dimensional Two 90° bends with 3- dimensional| | 35xD| 10xD
Shut-off valve| | 45xD| 10xD

RS-485 and Modbus

FDMO6 integrate a RS-485 interface for digital communication as an option feature. Based on Modbus protocol makes the general convenience on PLC, HMI and PC connection. For Modbus protocol information please download the file from website. Besides the PLC, HMI application, the user software provide the device setting and data logging function, it also can free download from website.

Technical Data :

Max. network size : 32 transmitters
Communication : with COM-Port (serial interface) of PC
Max. network expansion : 1200m (3937ft) total length at 9600 baud
Transmission rate : 9600, 19200, 38400, 57600, 115200 Baud
Parity : None, Even, Odd
Data length : 8 bit
Stop bit : 1 or2 bit
Factory default Station address = 1, Data format= 9600, N81

Autozero

The middle button allows user to set the current pressure to zero point. It is required to press the button about 5 seconds, and user can see A.2ro will be display. Then user can release this button and will see the prompt —-, and the new zero point has been set. Please make sure that the gas is completely still prior to execute this function.

This button also allows user to restore factory default setting. It is required to press the button about 10 seconds, user will first see F.2-o will be display. Then user can release this button and will see the prompt —-, and the new zero point has been set.

Software and configuration step

User may download the configuration software on eyc web site. Please decompress the application prior to execute it. Operating System requirements : above Windows XP. Other application program requirements : above Microsoft Office 2003

Hardware connection : Connect the FDMO06 to PC through USB to RS-485 or RS-232 to RS-485 converter
Check the COM port number from Device Manager in Computer Management. e.g.COM1inillustration
Open the FDMO6C Ul, go to function ” Interface ” ,click item ” Config” and then setting COM port, BAUD rate, data format and Station ID, pressed ” Apply ” for connection
Scan RS-485 connection
Open the FDMO6 Ul, go to function ” Interface” , clickitem ” Config” and then setting COM port, pressed ” Scan” bottom for scan devices and pressed ” Close and Export ” when the interested devices found
Pick up the device that you want to connect to and then press “Apply” to go.
Setting on Impulse Output
In the group of OUTL, Output tab. The output1l related setting could be found.
Quantity : Differential Pressure, Flow Velocity, Air Temperature, Flow Volume and Barometric Pressure
Responserate : 1*order low pass filter, T90 time 0 … 100 » higher value if lower fluctuation but longer response time, lower value if allow higher fluctuation but shorter response time.
Analogtype : 0..20mA/4…20 mA (if output current) / 0 … 10V (if output voltage)
Range for Upper and Lower
Alarm Mode: Check the box if analog output pretend a alarm switch output
Alarm Trigger Point: Upper and Lower
Alarm Output Level: Upper and Lower
Setting on Impulse Output (Optional, Only Available if Function Equipped)
In the group of OUT2, Output tab. The Impulse output related setting could be found.
Quantity : Differential Pressure, Flow Velocity, Air Temperature, Flow Volume and Barometric Pressure
Response rate : 1st order low pass filter, T90 time 0 … 100 > higher value if lower fluctuation but longer response time, lower value if allow higher fluctuation but shorter response time.
Impulse Value : The valence of single impulse quantity
Upper Range : Span upper point or maximum output. The span lower point always const zero.
Setting on RS-485, Process Parameters and offset adjustment
