Part A System installation and start-up

1 Electrical connection: power supply

1.1 Important installation notes PLEASE NOTE !

1.1.1 Location

• Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current
installations with line voltages up to 1000 V” or equivalent national regulations.

• Do not cross or loop cables inside the terminal compartment.

• Use separate cable entries (see below) for power supply, field current cables, signal lines,

outputs and inputs.

• Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight.
Fit a sunshade if necessary.

• When installed in switchgear cabinets, signal converters must be adequately cooled,
e.g. use fans or heat exchangers.

• Do not expose signal converters to intense vibration.

1.1.2 Onl

y for separate systems/signal converters (F- and E versions)

• Keep distance between primary head and signal converter as short as possible.

Refer to Sect. 1.3.4 for maximum permissible length of signal and field current cables.

• Use the supplied Krohne signal cable A (Type DS), standard length 10 m (33 ft).

• Always calibrate primary head and signal converter together. Therefore, when installing,

ensure primary constant GKL is identical; refer to instrument nameplate for the primary
head. If the GKL is not identical, set the signal converter to the GKL of the primary head.
Refer also to Sections 4.

• Dimensions of signal converter; refer to Section 10.4.

1.1.3 Cable entries (K- and F- versions)

Number of cable entries: 2 for the compact flowmeters

4 for the seperate IFC 020 F signal converter

NOTE: Ensure gaskets are fitted correctly and maintain

the following max. torques!

1 Max. torques for PG 13.5,

1/2“ NPT or 1/2“ PF adapters: 4 Nm / 2.8 ft

2 Max. torques for PG 13.5 only: 3 Nm / 2.1 ft

x

3 Gasket

A) PG 13.5 cable entries

These cable entries may only be used for flexible electrical cables if the relevant electrical
regulations so allow, e.g. National Electric Code (NEC).
Do not fix rigid metal conduits (IMC) or flexible plastic conduits to the PG 13.5 cable entries, refer
to “Point B, C” below (1/2” NPT or PF adapters).

B) 1/2“ NPT adapters C) 1/2“ PF adapters

For most North American systems the regulations require that electrical conductors be laid in
conduits, particularly where power voltages > 100 V AC are concerned.
In such cases, use the 1/2” NPT or 1/2” PF adapters to which flexible plastic conduits can be
screwed. Do not use rigid metal conduits (IMC)!
Lay conduits such that no moisture can penetrate into the converter housing.
Should there be risk of any condensation water forming, fill the cross-section of the conduit
around the cables at these adapters with a suitable sealing compound.

PLEASE NOTE !

• Rated values:

The flowmeter housings protecting the electronic equipment from dust
and moisture must always be kept closed. The selected creepage distances and
clearances have been dimensioned in conformity with VDE 0110 and IEC 664 for
contamination category 2. Supply circuits and output circuits are designed to meet the
standards of overvoltage class II.

• Safet

isolating facility.

• The PE protective ground conductor for the power supply must be connected to the

separate U-clamp terminal in the terminal compartment of the signal converter.
For exceptions (compact systems), refer to installation instructions for the primary head.

• Connection diagrams for electrical connection between primary head and

• If connected to a functional extra-low voltage source (24 V AC / DC, 48 V AC),
provide for protective separation (PELV) in conformity with VDE 0100 / VDE 0106 or
IEC 364 / IEC 536, or equivalent national regulations.

1.3.1

General remarks on signal lines A and B and field current line C

Proper operation of the equipment is ensured when Krohne signal lines A and B are used with foil
screen and magnetic shield.

• Signal lines must be firmly installed.

• Shields are connected via stranded drain wires.

• Underwater or underground routing is possible.

• Insulating material flame-retardant to IEC 332.1 / VDE 0742.

• Low-halogen, unplasticized signal lines which remain flexible at low temperatures.

1.3.2 Grounding of primary head

• All flowmeters must be properly grounded.

• The grounding conductor should not transmit any interference voltages.

• Do not ground any other electrical device together with this conductor.

• The primary head is connected to ground by means of an FE functional ground conductor.

• Special information on grounding various primary heads is contained in the separate

installation instructions for primary heads.

• These instructions also contain detailed descriptions on how to use grounding rings and
how to install primary heads in metal or plastic pipes or internally coated pipelines.

3 Start-up

• Before powering the system, please check that it has been correctly installed according

to Sect. 1 and 2.

• The flowmeter is delivered ready for operational use. All operating data have
been factory set in accordance with your specifications.

Please refer to Sect. 3.2 “factory settings”.

• Power the unit, and the flowmeter will immediately start process flow measurement.

• When powered, the display shows in succession: START UP and READY.

This is followed by display of the current flow rate and/or the current totalizer count
on either a continuous or alternating basis, depending on the setting under Fct. 1.04.

• Refer to Sect. 4 and 5 for operator control of the “display version”.

3.1 Power-on and measurement

3.2 Factory setting

All operating data are factory set according to your order specifications.

If you have not made any particular specifications at the time of ordering, the instruments will be
delivered with the standard parameters and functions listed in the Table below.

To facilitate easy and rapid initial start-up, current output and pulse output are set to process flow
measurement in “2 flow directions”, so that the current flowrate is displayed and the volumetric
flow counted independent of the flow direction. On instruments equipped with a display, measured
values may possibly be shown with a “ – ” sign.

This factory setting for the current and pulse outputs may possibly lead to measuring errors,
particularly in the case of volume flow counting:

for example, if pumps are switched off and a “backflow” occurs which is not within the range of the
low-flow cutoff (SMU), or if separate displays and counts are required for both flow directions.

To avoid faulty measurements, therefore, it may be necessary to change the factory setting of
some or all of the following functions:
– low-flow cutoff SMU, Fct. 1.03, Sect. 5.3
– current output I, Fct. 1.05, Sect. 5.6
– pulse output P, Fct. 1.06, Sect. 5.7
– display (option), Fct. 1.04, Sect. 5.4
