Basic display view
• Current flow rate Q [m

/h]
• Volumetric counter V [m
3
]
Both values are shown in 3 decimal places.
Display setting view
•
DO1 digital output: ±Imp / +Imp (bidirectional/unidirectional)
•
D02 digital output: Pos/Neg / +FS / Pha / +Imp / -Imp (direction of flow/monitor of
flow in positive direction/phase-shifted DO1 /impulses in positive direction/impulses
in negative direction where the impulse constant is always equal as in DO1)
•
Flow mFS [l/h] (at DO2 output): switching point in positive direction of flow /
hysteresis in per cents
•
AO analogue output: ±Loop/+Loop (Current loop active during the flow in both
directions / in positive direction whereas the setting is specified by DO1 mode)
•
Limit of current output [l/h]: for 4mA / for 20mA / offset for 4mA / offset for 20mA
•
Starting flow rate measurement: ±Q [l/h]
•
Flow direction: Inlet/Outlet (in the direction of the arrow on the meter’s name-plate
•
Flow rate simulation: +Q [l/h] (for verification of the flow meter functionality and
connection to a higher-level system, after 3 minutes, the flow meter goes back
automatically to measurement mode)
•
Factory reset: (restoring the meter to factory default state)
Corresponding set point values are displayed according to output pre-selections. Possible
output combinations correspond to the previous
Possible output configurations Table.
Display warning or error views
• Excitation circuit error
• Impulse output flooding
• Unstable measuring signal
• Signal out of measuring window
Warning or error messages displayed are flashing in regular intervals and a LED indicator
according to message type is also lit (Error — red LED, warning — amber LED) and the D03
digital status output is activated at the same time.
If you wish to change parameters, you need to initiate the setup mode within 3 minutes after
powering of the meter (the command to modify setting is sent via the communication
interface, or E-button is pressed and held for approx. 4 seconds). After this period is over, it is
only possible to view the current settings, the modification of parameters is blocked). Button
↑ changes parameters and button E confirm values.
