Maintenance
If operated in comtaminated or calcareous
water deposits can build up, which can
lead to measuring errors. Thus it may
be necessary to clean the section of the
sensor through which the liquid passes.
Please proceed carefully when cleaning
to ensure that the fl ow channel with its
sensor elements is not damaged.
Electrical connection (S175)
Operation
The inline fl ow meter has front panel
buttons for setting functions to display set-
tings. All values are indicated via the
3-digit 7-segment display.
Button [S1/-]:
After a short press of
the button, the set limit value for switch
point S1 is indicated. In the programming
mode, this button can also be used to
decrease the indicated value.
Button [mA/+]:
After a short press of the
button, the actual current value in mA is
indicated. In the programming mode, this
button can also be used to increase the
indicated value.
Button [M]:
After activation the program-
med values are displayed for 3 s.
In the programming mode, this button
can also be used to select functions and
parameters.
Programming
To enter the programming mode, press
buttons
[S1/-]
and
[mA/+]
for at least 3 s
until the display starts fl ashing. For a short
moment the character string
[Cod]
is
displayed. Followed by the number
[0]
, which can be modifi ed according to
the valid access code using buttons
[S1/-]
and
[mA/+]
. Use button
[M]
to
subsequently select the required para-
meter. After selection, the parameter is
displayed for approx. 2 s, followed by the
associated value which
can now be modifi ed. During entry it is
automatically verifi ed whether the set pa-
rameter is admissible. Two decimal points
of the display will fl ash to warn against an
invalid entry. To terminate programming
and save all values press button
[M]
for at
least 3 s until the display stops fl ashing.

Access code [Cod]:
Without entry of an access code it is not
possible to set or modify device parame-
ters. The ex factory setting is “0”. This
value can be modifi ed at the end of the
programming menu.
Adjustable range switch point
S1 [SP]:
The switch point S1 is entered in l/min.
The switch point may be placed anywhere
within the total adjustable range (see page
7 and 10).
Hysteresis switch point S1 [hs]:
The hysteresis is the difference between
the switch-on value (which is identical to
the programmed switch point S1) and the
switch-off value. It is entered in l/min (see
page 7 and 10).
Output switch point S1 [OU]:
The switching output S1 can be adjusted
either for the N.O. or N.C. mode.
Switch-on delay switch point
S1 [dS]:
If it is not required to update the output
signal immediately after the switch point
S1 has been exceeded, this value can be
set in a range from 0…50 s. The signal
will then only be updated after the set
time has expired, provided the limit is still
exceeded.
Switch-off delay switch point
S1 [dr]:
If it is not required to update the output
signal immediately after the switch point
S1 has been underranged, this value can
be set in a range from 0…50 s. The signal
will then only be updated after the set
time has expired, provided the limit is still
underranged.
Average forming [nF
I
]:
This parameter permits the entry of a
value which defi nes the time interval
during which a measuring value average
is formed. Values between 0…8 s can be
entered.
A low value will lead to a fast response,
whereas a high value steadies the dis-
play of the measuring value. In 0 postion
the average forming is switched off. The
average forming has an infl uence on the
display and the current output.
Parameter, Operations and Functions
Analogue output [A4] and [A20]:
These two values determine the fl ow
range.
[A4]
is assigned a minimum value
in l/min and a current value of 4 mA.
[A20]
is assigned a maximum value of
l/min and a current value of 20 mA.
Only a minimum difference of 10 l/min is
allowed between the two values. In the
event of an error in the measuring system,
a current of 2 mA is output.
Reset function [rES]:
Use the RESET function to set all values
back to the ex factory settings. For this,
the device must be disconnected from
power. Button
[M]
is then pressed during
re-connection. The character string
[rES]
is displayed. Then you will be prompted
to enter the access code. Press
[M]
to
confi rm the entry and carry out the reset.
