have max. frequency programmed.
LIMITS : No limits
APPEARS : If meter type is HEAT METER or NET
HEAT METER and Fct. 1.3.5. VARIABLE F is
POWER or NET POWER.
Fct. 1.4.6 F.S.FREQ.
Enter maximum frequency required for maximum
power programmed in Fct. 1.4.5 F.S. POWER
LIMITS : Maximum 10,000 Hz.

HEAT METER and Fct. 1.3.5. VARIABLE I is
POWER or NET POWER
Fct. 2.0 TEST.
This second main menu level groups test functions
for display, current output and frequency output.
There are no sub-menus under 2.0. Since these are test
functions, when executed they have an immediate
effect on the signal converter for the duration the test
function is executed. When using all the other menu
functions, the changes made are stored temporarily
and have no effect on the operation of signal
converter unless you quit menu and respond with YES
to update changes.
APPEARS - Always
Fct. 2.1 TEST DISP. display test
All segments of the display are tested in the following
sequence. Alphanumeric field, numeric field, arrow
and key markers. You can press the E key at any time
to terminate display test. Executing display test does
not affect the normal operation of the signal
converter.
LIMITS - Not applicable
APPEARS - Always.
Fct. 2.2 TEST I current output test
CAUTION: During this test, current output will
change to test values so you should take
appropriate actions depending on how you are
using current output.
Place current meter in series with current loop then
select one of the following values.
l 0 mA l 2 mA l 4 mA
l 10 mA l 20 mA l 22 mA
Selecting any value will cause that current to flow so
that you can check on meter. Select CONT. YES to
test other current value or CONT.NO to end. When
the menu function finishes, normal current value
depending on flow rate and programming of current
output function will be restored.
LIMITS - Not applicable.
APPEARS – Always
Fct. 2.3 TEST F frequency output test
CAUTION: During this test frequency output will
change to test values so you should take
appropriate actions depending on how you are
using frequency output
Connect frequency meter to frequency output. Select
one of the following test values.
l 1 Hz l 10 Hz l 100 Hz
l 1000 Hz l 10000 Hz
Selecting any value will cause that frequency to
output so that you can check on meter. Select
CONT.YES to test other frequency value or
CONT.NO to end. When the menu function finishes,
normal frequency value depending on flow rate and
programming of frequency output functions will be
restored.
LIMITS - Not applicable
APPEARS - Always
Fct. 3.0 INSTALL
This is a main menu level whose submenus and their
functions cover all installation related functions which
include
- Primary data (nominal diameter, k-factor)
- User data (language, password, totalizer setting etc.)
- Operating limits ( P & T operating limits).
- Application data (medium, P & T operating etc.).
- Sensor options and pressure sensor data.
APPEARS – Always
