3 Start-up
3.1 Powering
up
and
measurement
The flowmeter is delivered ready for use. All operating data have been factory set in accordance with your
specifications.
Power the unit, and the flowmeter will immediately start process flow measurement.
Basic version, signal converter IFC 010 _ / B
A light emitting diode (LED) under the cover of the electronic section shows the measurement status.
LED flashing . . .
green:
measurement correct, everything all right.
green / red:
momentary overdriving of outputs
and/or A/D converter.
red:
fatal error, parameter error or hardware fault,
please consult factory.
Display version, signal converter IFC 010 _ / D
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.
3.2 Factory
settings
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, or if separate displays and counts are required for both flow directions.
To avoid faulty measurements, it may therefore, be necessary to change the factory settings of some or all of the
following functions:
– low-flow cutoff, Fct. 1.03
– current output I, Fct. 1.05
– pulse output P, Fct. 1.06
– display (option), Fct. 1.04
