Relay switches when the measured value exceeds the
upper limit.
Relay switches when the measured value falls below the
lower limit.
Relay switches when the flow changes its direction (sign-
change of measured value).
Relay switches when the totalising function is selected
and the flow reaches or exceeds the programmed limit (in
flow direction determined by the sign).
Relay switches when no measurement is possible.
No function, the relay contact is always open.
TYP

Set-up of the relay
holding behaviour)
NON HOLDING
HOLDING
Relay falls back into the de-energised position after
approx. 1 second (
$
MODE) if the switching condition
(FUNC
%
) is not true any more.
Relay will stay in switched state (
$
MODE) even if the
switching condition is not true any more (FUNC
%
).
During measurement, this key will switch all
relays to their de-energised position. If the
switching condition is still met, however, the
contacts will switch back into their active state
after 1 second.
MODE
(Switch:
Set-up of the relay
state in de-energised
condition)
NO Contact
NC Contact
Relay contact closes when the switching condition (FUNC
%
) is true, i.e. the contact is open when in its de-
energised position (NO=normally open).
Relay contact opens when the switching condition (FUNC
%
) is true, i.e. the contact is closed in its de-energised
position (NC=normally closed).

ATTENTION:
This key will bring you back to the MAIN
MENU.
All relay coils will be de-energised,
i.e. all relay contacts will be opened
independent of their programmed state.
Set-up of the limit values:
If you have selected under FUNC the switching conditions MAX, MIN or QUANTITY, you
can input the desired limit values for the alarm outputs as follows:
Function Display and comparison Remarks
MAX
0.00 m3/h
High Limit
comparison: measuring value > limit
O22
The comparison will take the sign
into consideration!
Example: Input -10.0.
The limit will be exceeded by a measured value
of -9.9 m3/h or +2.5 m3/h. The relay
won't
switch if, for instance, the measured value
amounts to -11.0 m3/h.
