Hazardous Area requirements

• Hazardous Area Installation.

• For further information please see supplementary installation and operating instructions.

• Please follow these guidelines explicitly for mechanical and electrical connections.

• General cabling guidelines.

To maintain the IP 67 / NEMA 4x protection it is necessary to ensure that the correct size cable is used for

the cable glands. Please ensure that the cable glands are well tightened. Provide a “drop” loop for water

to drip off.

2.5 Inputs and outputs

2.5.1 Inputs/Outputs MFC 050

The MFC 050 has many options and variations for the inputs/outputs.

The meter is shipped from the factory with one of the following options pre-configured:

Option Function

1 1 x current,1 x pulse,1 control input,1 x status output-HART

2 1 x current plus Modbus

3 Dual phase frequency output, 1 x current, 1 x control input - HART

4 2 x current, 1 x pulse, 1 x control input, HART

5 2 x current, 1 control input,1 x status output-HART

6 3 x current, 1 x pulse - HART

7 3 x current, 1 x control input - HART

8 3 x current, 1 x status output - HART

If you are not sure what option is fitted to the converter, this may be viewed at program Fct. 4.1 IO

FITTED.

On the MFC050, the inputs/outputs have a common signal ground that is galvanically isolated from the

Potential Earth (PE).

Note

HART

is available on the first current output except for option 2, where a communication option is already

available.
