'enter', the changes will be used by the controller. Could be used for large setpoint steps. What is

displayed here in this menu depends on the selection of the setpoint source. Analog setpoints

can not be edited. 1300 0000 Setpoint full. After pressing 'enter', setpoint for controller will be 100% unconditionally (controller

valve will be opened in almost all situations). 1400 0000 Setpoint zero. After pressing 'enter', setpoint for controller will be zero unconditionally (controller

valve will be closed in almost all situations). You will return to the readout display now. Setpoint will not respond to selected source again until 'enter' has been pressed in menu 1000.

NOTE:

Measured values could be readout up to 110.0%.

Sensor signals > 110.0% will be cut-off.

Setpoint can be entered up to 100.0%. However, setpoint signals can, just like sensor signals, be

corrected by means of polynomial calculation.

Also you can use setpoint offset correction to eliminate cable offsets in your system (see

operation menu).

by itself and install there. 8120 0000 Remote Install. Press 'enter' to let this module get into INIT mode so it can be installed to the bus by an external

device (operation module or PC). You have one minute now to perform the installation

procedure. 8130 0000 Start Communication. When you press 'enter' in this menu communication with the bus will be (re)started (use after

stopping communication temporarily). When the device is properly installed, it will start

communication at power-up and after a reset automatically. 8140 0000 Stop Communication. When you press 'enter' in this menu communication with the bus will be stopped until ‘Start

communication' will be selected or at a reset of the module. 8200 0000 Check Settings. Here you check FLOW-BUS settings of this module.

8210 0000 PNA means Primary Node Address of module on the FLOW-BUS. NNA means Next Node Address. This address points to the next module on the FLOW-BUS and

will be changed automatically if a new module is add to the FLOW-BUS behind this module. If

the module is the last module on the FLOW-BUS, its NNA points to zero. 8211 0000* Here you can change the PNA of the module. If you give a new address, the module will restart

the communication. The NNA is default set to PNA+1. During communication NNA values may

change automatically because FLOW-BUS optimises it self for optimum communication speed.

NOTE 1:

Normally installation on the FLOW-BUS has to be performed only one time. Mostly this will be

done at Bronkhorst High-Tech B.V. when your module has been built and tested. The address on

the bus for this module will be stored when the module powers-off. At future power-on situations,

it will be part of the FLOW-BUS on the same address each time. However, there can be

situations you have to install your module on the bus again. For example:

1) When you want to rebuild your FLOW-BUS system.

2) When you want to add this module to another FLOW-BUS system.

3) When, at the check at start-up, the module finds out that its address to be on the FLOWBUS is occupied already by another module. You will get a message on your display That you have to re-install the module on the bus.

NOTE 2:

Make sure this module has been switched-off before connecting it to the FLOW-BUS. First make FLOW-BUS connection, then switch-on the power. Only in this order the module is able to perform its communication checkings properly.

How to install the E-7000 modules on the FLOW-BUS network, see manual 9.17.024.

* LNA means last Node Address. This is an indication of the size of the FLOWBUS network. The next module added to the network should have a PNA below this LNA. When a module is automatic installed on the network, this LNA will be changed automatically.

3.11 Calibration with polynomial functions

3.11.1 General information

A normally calibrated device will have linearized transfer functions. This means that real flow/pressure and setpoint are proportional to the output signal (0-5 V, 0-10 V, 0-20 mA or 4-20 mA). A polynomial function is a method of approximation which mathematically describes a continues transfer function. By means of a few samples, a polynomial function can be obtained. After determining the polynomial function, the original calibration points and an infinite amount of values in between, can be calculated with high accuracy. In a system where pressure- and/or flow meters and -controllers should be readout and set with high accuracy, these polynomial functions often are used for approximation of their transfer function. For instance the function which describes the relation between output voltage and measured flow.

3.11.2 General form

The general form of a polynomial function of the n-nd degree is as follows:

Y = a0 + a1 · X + a2 · X

Where 'a0' to 'an' are polynomial parameters, which can be calculated. When you have 'n + 1' measure-points, they can be approximated by means of a 'n-nd' degree polynomial function.

3.11.3 Polynomial functions of sensor signal and setpoint

By means of a calibration at Bronkhorst High-Tech B.V. several measure points will be used to obtain a polynomial function. The form of this function is:

Y = a + b · X + c · X

In which 'Y' is the measured value in correct unit (e.g. flow in [ln/min]) and 'X' is the value of output signal in correct unit (e.g. Uout in [V]). Characters 'a - d' are polynomial parameters, which can be obtained by a mathematical program. These parameters can be filled in and the polynomial function is completed. Now a flow can be calculated out of the sensor output signal of the device.

When a controller is calibrated, also a polynomial function for setpoint is calculated. This will be the inverse function of the polynomial function of the sensor signal. The form of this function is:

Z = e + f · Y + g · Y

In which 'Y' is the measured value in correct unit again (e.g. flow in signal in the correct unit (e.g. [V]).

Characters 'e - h' are parameters, which can be filled in. Now the desired setpoint signal can be calculated out of the amount of flow at which the controller has to operate.

3.11.4 Presentation of parameters

Parameters 'a - d' and 'e - h' are polynomial function parameters, which can be obtained with a mathematical program out of measured calibration points.

All parameters will be printed on the calibration certificate. They will be presented in scientific notation with 5 significant digits, where the last digit is obtained by rounding-off.

Example (unscaled):

a = -2.7458 · 10 b = +9.5452 · 10-1 f = +1.0892 c = -1.2714 · 10-1 g = +1.7832 · 10-2 d = +1.8464 · 10

3.11.5 Using polynomial functions at readout/control unit

The parameters for the polynomial functions are stored at the readout and control-module and can be changed from the keyboard. Normally both transfer functions of sensor signal and setpoint are linear Y = X, the transfer function of the setpoint signals is Z = Y. The connected device will have linearized transfer functions after (normal) calibration. The accuracy however, will be ≤ 1 % full scale. When a special polynomial function calibration is wanted, the parameters 'a-h' will be destillated and printed on the calibration certificate. In the 'INSTRUMENT'-menu you just have to enter these values. Now you can connect and operate the concerned device.

Note:

Only this device will operate correctly; if you want to connect an other device to this channel, first change the polynomial function parameters.

4.1 General information

Before operating your system be sure that it is setup to readout and control digital (FLOW-BUS) instruments. Check: model configuration; sensor output signal. The code should be “R” Use 'cursor' keys to scroll through the menu-structure and to select the required menu level. The 'enter' key is used to acknowledge a selected setting and to enter a edited value and/or text. Editing can be performed by using the 'cursor' keys to select the character to be edited ( ← / → ) and to scroll through the available character set or units ( ↑ / ↓ ). After power-up the display will show the usual start-up sequence for some seconds.
