IFC 300

 

 

 

2.1 Intended use

The electromagnetic flowmeters are designed exclusively to measure the flow and conductivity of electrically conductive, liquid media.

DANGER!

For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.

WARNING!

If the device is not used according to the operating conditions (refer to chapter "Technical data), the intended protection could be affected.

2.2 Scope of delivery

INFORMATION!

Inspect the cartons carefully for damage or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer.

INFORMATION!

Check the packing list to check if you received completely all that you ordered.

INFORMATION!

Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.

2.3Storage

Store the device in a dry, dust-free location.

Avoid continuous direct sunlight.

Store the device in its original packing.

Storage temperature: -50...+70°C / -58...+158°F

2.4Transport

Signal converter

• No special requirements.

Compact version

Do not lift the device by the signal converter housing.

Do not use lifting chains.

To transport flange devices, use lifting straps. Wrap these around both process connections.

2.5Installation specifications

INFORMATION!

The following precautions must be taken to ensure reliable installation.

Make sure that there is adequate space to the sides.

Protect the signal converter from direct sunlight and install a sun shade if necessary.

Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat exchanger.

Do not expose the signal converter to intense vibration. The flowmeters are tested for a vibration level in accordance with IEC 68-2-3.

Figure 2-4: Turning the display of the field housing version

The display of the field housing version can be turned in 90° increments.

1Unscrew the cover from the display and operation control unit.

2Using a suitable tool, pull out the two metal puller devices to the left and right of the display.

3Pull out the display between the two metal puller devices and rotate it to the required position.

4Slide the display and then the metal puller devices back into the housing.

5Re-fit the cover and tighten it by hand.

CAUTION!

The ribbon cable of the display must not be folded or twisted repeatedly.

INFORMATION!

Each time a housing cover is opened, the thread should be cleaned and greased. Use only resinfree and acid-free grease.

Ensure that the housing gasket is properly fitted, clean and undamaged.

3.1 Safety instructions

DANGER!

All work on the electrical connections may only be carried out with the power disconnected. Take note of the voltage data on the nameplate!

DANGER!

Observe the national regulations for electrical installations!

DANGER!

For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.

WARNING!

Observe without fail the local occupational health and safety regulations. Any work done on the electrical components of the measuring device may only be carried out by properly trained specialists.

INFORMATION!

Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.

3.2 Important notes on electrical connection

DANGER!

Electrical connection is carried out in conformity with the VDE 0100 directive "Regulations for electrical power installations with line voltages up to 1000 V" or equivalent national regulations.

CAUTION!

Use suitable cable entries for the various electrical cables.

The sensor and converter are configured together in the factory. For this reason, please connect the devices in pairs. Ensure that the sensor constant GK/GKL (see type plates) are identically set.

If delivered separately or when installing devices that were not configured together, set the converter to the DN size and GK/GKL of the sensor.

3.3 Electrical cables for remote device versions, notes

3.3.1 Notes on signal cables A and B

INFORMATION!

The signal cables A (type DS 300) with double shield and B (type BTS 300) with triple shield ensure proper transmission of measured values.

Observe the following notes:

Lay the signal cable with fastening elements.

It is permissible to lay the signal cable in water or in the ground.

The insulating material is flame-retardant to EN 50625-2-1, IEC 60322-1.

The signal cable does not contain any halogens and is unplasticized, and remains flexible at low temperatures.

The connection of the inner shield is carried out via the stranded drain wire (1).

The connection of the outer shield is carried out via the shield (60) or the stranded drain wire (6), depending on the housing version. Observe the following notes.

The signal cable type B cannot be used with options with "virtual reference"!

3.3.2Notes on field current cable C

DANGER!

All versions except TIDALFLUX:

A non-shielded three-wire copper cable is sufficient for the field current cable. If you nevertheless use shielded cables, the shield must NOT be connected in the housing of the signal converter.

Only TIDALFLUX:

A shielded two-wire copper cable is used as the field current cable. The shielding MUST be connected in the housing of the measuring sensor and signal converter.

INFORMATION!

The field current cable is not part of the scope of delivery.

3.3.3 Requirements for signal cables provided by the customer

INFORMATION!

If the signal cable was not ordered, it is to be provided by the customer. The following requirements regarding the electrical values of the signal cable must be observed:

Electrical safety

• To EN 60811 (Low Voltage Directive) or equivalent national regulations.

Capacitance of the insulated conductors

Insulated conductor / insulated conductor < 50 pF/m

Insulated conductor / shield < 150 pF/m

Insulation resistance

Riso > 100 GΩ x km

Umax < 24 V

Imax < 100 mA

Test voltages

Insulated conductor / inner shield 500 V

Insulated conductor / insulated conductor 1000 V

Insulated conductor / outer shield 1000 V

Twisting of the insulated conductors

• At least 10 twists per meter, important for screening magnetic fields.
