1.1 Software History

The "Electronic Revision" (ER) is consulted to document the revision status of electronic equipment according to NE 53 for all GDC devices. It is easy to see from the ER whether troubleshooting or larger changes in the electronic equipment have taken place and how that has affected the compatibility.

Changes and effect on compatibility

1 Downwards compatible changes and fault repair with no effect on operation (e.g. spelling

mistakes on display)

2-_ Downwards compatible hardware and/or software change of interfaces:

HART

P PROFIBUS

F Foundation Fieldbus

M Modbus

X all interfaces

3-_ Downwards compatible hardware and/or software change of inputs and outputs:

I Current output

F, P Frequency / pulse output

S Status output

C control input

CI Current input

X all inputs and outputs

4 Downwards compatible changes with new functions

5 Incompatible changes, i.e. electronic equipment must be changed.

5 START-UP

5.1 Switching on the power

Before connecting to power, please check that the system has been correctly installed. This includes:

• The device must be mechanically safe and mounted in compliance with the regulations.

• The power connections must have been made in compliance with the regulations.

• The electrical terminal compartments must be secured and the covers have been screwed

on.

• Check that the electrical operating data of the power supply are correct.

• Switching on the power.

5.2 Starting the signal converter

The measuring device, consisting of the measuring sensor and the signal converter, is supplied ready for operation. All operating data have been set at the factory in accordance with your order specifications.

MFC 300

When the power is switched on, a self test is carried out. After that the device immediately begins measuring, and the current values are displayed.

Figure 5-1: Displays in measuring mode (examples for 2 or 3 measured values) x, y and z denote the units of the measured values displayed

It is possible to change between the two measured value windows, the trend display and the list with the status messages by pressing the keys ↑ and ↓. For information about possible status messages, their meaning and cause refer to page 113.

CAUTION!

The use of a jumper is only permitted for custody transfer devices to lock the access to custody transfer relevant parameters. For non custody transfer devices (i.e. process instruments) this jumper must not be used!

INFORMATION!

•

The switching point for the 4 optical keys is located directly in front of the glass. It is recommended to activate the keys at right angles to the front. Touching them from the side can cause incorrect operation.

•

After 5 minutes of inactivity, there is an automatic return to measuring mode. Previously changed data is not saved.

Following activation of the IR interface in Fct. A6 or C6.6.6 the interface must be properly positioned and attached to the housing with the suction cups within 60 seconds. If this does not happen within the specified time period, the device can be operated using the optical keys again. Upon activation, the LED 3 lights up and the optical keys no longer function.

6.2 Zero calibration (menu C1.1.1)

Following installation, perform zero calibration prior to commissioning the device. Finalise the installation before performing zero calibration. Changes (pipe system or calibration factor) made after the zero calibration may affect the accuracy, making it necessary to perform zero calibration again.

Observe the following for reliable zero calibration:

• The measuring sensor should be completely filled with the product at the expected process pressure and temperature.

• The product may contain no air or gas, especially when it comes to horizontal installations. Prior to zero calibration, it is recommended that the product be flushed at a high flow rate (>50%), for 2 minutes.

• After flushing, re-establish zero flow by closing off the corresponding valves.

Set zero calibration automatically or manually using the operating controls. The converter cover must be installed on the display for automatic calibration.

Storing the displayed zero calibration.

Under certain conditions, zero calibration is not possible and will be cancelled:

• The product is still flowing. The shut-off valves are not closed tightly enough.

• There are still gas bubbles in the fluid.

Remedy: Flush sensor and repeat calibration

With some media, it may be difficult to perform zero calibration. In such cases, there are various methods to still achieve good zero calibration:

Medium Possible solutions

Media that tend to evaporate or outgas Increase pressure.

Two-phase media (slurries), that contain solids that may fall out.

Two-phase media in which the solids or gasforming components cannot be separated.

Only fill the sensor with the carrier medium.

Fill sensor with another liquid, e.g. water.

6 OPERATION

6.5.3 Mode (menu A8)

The device can be switched to "standby". In this mode, all flow values are set to zero and the counter values are "frozen". The temperature and density values are displayed normally and output via the outputs. The "standby" indicator on the display shows either the "frozen" counter value or simply "standby". In this mode, the measuring tubes continue to vibrate and the device can immediately return to "measuring" mode if necessary.

There is also a "stop" mode. In this mode, the sensor is switched off and is no longer vibrating. To return to measuring mode from this mode, the measuring device must complete "start-up" phase again before measurement continues.

The measuring device can be switched into "standby" mode either using the optical keys on the display or using the control input. You can only switch to "stop" mode using the optical keys.

Setting the mode (from measuring mode):

the key.

If "standby" or "stop" is selected, the device immediately switches to this operating state. To return to the measuring mode, go to menu A8 and select "measure".

INFORMATION!

When changing from the "stop" to "standby" mode, the device goes through the entire start-up phase.

In addition to the "standby" mode, the system control function also allows you to switch to a comparable "standby" status completely automatically depending on the current operating temperature or density.

6.5.4 Density calibration (menu C1.2.1)

Mass flowmeters are calibrated for density in the factory. Density calibration is based on 2 calibration points. In the factory, air and water are used under reference conditions. The result of this calibration is saved in the converter electronics and stored in the factory settings. Regardless, various applications require maximum accuracy which can only be achieved with on-site calibration.

Available options:

1 Point Calibration One of the 2 saved calibration points is replaced by customer calibration.

6 OPERATION

On-site density calibration:

• Ensure that the device has been properly installed and functions smoothly.

• If air (empty) is used as the medium, the measuring tube must be completely dry and free of

liquids and solids. If possible, blow dry air into the measuring tube to empty it.

• If liquids are used, flush for a few minutes at a high flow rate to remove gas bubbles.

• Set the flow rate to a typical value (50% of the nominal flow is ideal).

• If the process temperature is higher than the ambient temperature, wait until the system has

stabilised.

• When it comes to 1 point and 2 point calibration, you can choose from the options "empty", "pure water", "town water" and "other". The reference values for the specified products are stored in the converter.

Density calibration has failed if "calib. error." is displayed. There are several possible reasons for this:

• The device is not in "measuring" mode.

• The calibration points are too close together.

• One or more calibration points did not pass the plausibility test.

• Flow, pressure, temperature or system are not stable?

• Please check your system and try again.

• If this results in another failed calibration, please contact the manufacturer.
