Device configuration

The device can be factory calibrated to customer specifications
upon request. If no customer information is available, the device
is delivered with factory settings.
On-site configuration requires only a few parameter settings.
For entry or selection of parameters, refer to the section titled
'Entering data in short form'. A short overview of the menu
structure can be found in the section titled 'Parameter overview'.
The Easy Set-up menu enables users to configure the unit quickly
and conveniently, see Easy Set-up, for uncomplicated
parameterization on page 49.
The following parameters should be checked or set for
commissioning:
1. Upper range value (menu item 'Q
The device is factory calibrated to the largest flow range end
value, unless customer information to the contrary is
available. Upper range values that correspond to a flow
velocity of 2 to 3 m/s are ideal. First set the unit Q
m
/h oder l/s) in the menu item 'Unit' and then the upper
3
range value in menu item 'Q
possible upper range values are shown in Table Nominal
diameter, nominal pressure, measuring range on page 25.
2. Current output (menu item 'Current output')
Selected the desired current range here (0 to 20 mA or
4 to 20 mA)
3. For devices with a fieldbus, the bus address must be set
(menu item 'Interface').
4. Pulse output (menu items 'Pulse' and 'Unit').
To set the number of pulses per volume flow unit, a unit for
3
the totalizer (e.g., m
or l) must be selected in the menu item
'Unit'. Afterward the number of pulses has to be entered in
the menu item 'Pulse output'.
5. Pulse width (menu item 'pulse output')
For external processing of the counting pulses at terminals
51 and 52, the pulse width can be set between 0.1 ms and
2000 ms.
' and menu item 'Unit').
max
(e.g.
max
'. The smallest and largest
max
6. System zero point (menu item 'Syst.-Adjust')
When commissioning an older model flowmeter sensor or
checking the system, you can set the system zero point on
the transmitter after a warmup period. The fluid in the
flowmeter sensor must be at absolute standstill. The
measuring tube must be completely full. The adjustment can
now be made manually or automatically on the transmitter
via the 'System zero point' parameter. Select the parameter
by pressing ENTER, use the arrow buttons for example to call
up 'automatic' and press ENTER again to start the
adjustment. The adjustment runs approx. 60 seconds and
should be within a range of ± 10%. If the value measured is
outside this limit, no calibration is performed. The
adjustment can also be performed via the external switch
input / ext. sys. zero point (see parameter Switch input on
page 77).
7. Detector empty pipe
(Menu item 'Detector e. pipe'), for devices with nominal
diameter DN 10 and/or without preamplifier.
When the 'Standard' DEP mode is selected, you do not need
to perform an adjustment on site. The transmitter works
with standard setup data. If the function is not performed
correctly, a new adjustment must be run with the fluid onsite.
The adjustment can be made with a full or empty meter pipe.
8. Extended diagnostic functions
To measure the DC resistance or the coil temperature, the
signal cable length must be entered. To use the functions
Electrode voltage, Electrode balance and Electrode state, the
electrode zero must be adjusted. See submenu Alarm Coil
Current on page 85 or Additional information regarding use
of enhanced diagnostic functions on page 97.
Note
If the flow indicator shows the incorrect flow direction after
successful commissioning of the measuring system, e.g., reverse
instead of forward, correct this in the 'Operating mode
submenu' of the transmitter.
First switch off the programming protection ('Prog. Level' 
'Specialist'). Then select the parameter 'Directional display' in
the 'Operating mode submenu' and change 'normal' to 'inverse'.
Finally, reactivate programming protection by selecting 'Prog.
Level'  'Locked').
