Product description
12
The colour of the product status indicator gives the following pieces of information:
▪Whether product diagnostics are active or not. Diagnostics are active on the product and cannot be de-
activated.
▪If product diagnostics are active, then the product status indicator shows whether diagnostics events
have been generated or not. If several diagnostics events have been generated, then the product status
indicator shows the diagnostics event with the highest priority. Refer to table [}12]
If the product status indicator flashes, then the product is selected in a man-machine interface such as the
Bürkert Communicator software.
Colour 1Colour code (for a
PLC)
Diagnostics event
Red 5 Failure, error or fault
Due to a malfunction of the product or its periphery.
▪MFC Batch: The measured values are not valid and the product cannot dose any
more.
Orange 4 Check function
The product is being worked on.
▪MFC Batch: The product cannot dose temporarily.
Yellow 3 Out of specification
The ambient conditions or process conditions for the product are outside the spe-
cified ranges.
Product internal diagnostics point to problems in the product or with the process
properties.
The yellow state is displayed for about 15 seconds after electrical power up.
The Coriolis sensor needs this time to reach the normal operating mode.
After this initialization the device will change to the green state.
▪MFC Batch: The product continues to dose
Blue 2 Maintenance required
Do the required maintenance operation.
▪MFC Batch: The product continues to dose, but a function is temporarily restric-
ted.
Green 1 -
Diagnostics are active and no diagnostics event has been generated.
▪MFC Batch: The product operates in the normal operating mode.

3.4 Memory card
If the memory card is defective or lost, then buy a new memory card from your Bürkert sales office.
The product is delivered with a memory card that is inserted in the product.
When the product is energised, there are two possibilities:
▪If product-specific data is stored on the inserted memory card, then the product adopts the data. At
product delivery, the memory card contains product-specific data. To get a list of the stored data, refer
to the Help for the Initiation file that can be downloaded from country.burkert.com.
▪If the inserted memory card is empty, then the product loads its own data on the memory card. A new
memory card is empty.
The data on the memory card can be transferred to another product with the same article number. For ex-
ample, the data can be transferred from a defective product to a new product.
3.5 Actuator is an on/off valve
The product is fitted with one of the following on/off valves:
▪Type 6013
▪Type 6724
Refer to the Type label of the on/off valve.
3.6 Customised actuator
An MFC for modular actuator can be combined to the following actuators:
▪a proportional valve
▪an on/off valve
When selecting the actuator, observe the following basic data of the MFC for modular actuator:
▪nominal flow rate
▪inlet pressure
▪...
3.7 Service life of the on/off valve
The service life of the on/off valve is reached when at least on the following problems occurs:
▪the product does not dose correctly any more
▪the on/off valve is not tight any more
