Switching on supply power
After switching on the supply power, the flowmeter sensor data in the external FRAM is
compared with the data saved internally. If the data is not identical, the transmitter data is
replaced automatically. Once completed, Warning 7 "Flowmeter sensor data loaded" and
Warning 8b "Update external FRAM" are displayed. The measuring equipment is now ready for
operation.
The display shows the current flowrate.

Device configuration
The device can be configured at factory 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 information on settings, refer
to the "Entering data in short form". A short overview of the menu structure can be found in the
section "Parameter overview".
The Easy Set-up menu enables users to configure the unit quickly and conveniently, see
chapter "6.3 Easy Set-up: For uncomplicated configuration".
The following parameters should be checked or set before start-up:
1. Flow range end value (menu items "Q
The devices factory setting is largest flow range end value, unless other customer
information is available. The ideal flow range end values are approximately 2 ... 3 m/s. First
set the unit Qmax (e.g., m
value under "Qmax". The smallest and largest possible flow range end values are shown in
table "Flowmeter Sizes, Pressure Ratings, Flow Range" page 29.
2. Current output (menu item "Current output")
Select the desired current range (0 ... 20 mA or 4 ... 20 mA)
3. For devices with a fieldbus, the bus address must be set (menu item "Data Link").
4.Pulse output (menu items "Pulse" and "Unit").
To set the number of pulses per volume flow unit, a unit for the totalizer (e.g., m
be selected under "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, the pulse width at terminals 51 and 52 can
be set between 0.1 ms and 2.000 ms.
