Emerson Rosemount 326L, Быстрый старт

Страница: 39 / 52

To correctly transfer the microwave pulse to the tank with optimum transmission power,
the level transmitter needs a sufficiently large metal launching surface or launching plate.
For installation in closed metal tanks or metal bypass pipes, the tank lid or upper pipe
section serves as a launching surface. Use a sufficiently large fixing plate, metal plate or
something similar when installing in open metal tanks, plastic tanks, or metal tanks with
plastic lids. For more information, see
Installing in an open tank or Installing in a plastic
tank .
3.5.2 Operation with a bypass or still pipe
Use a bypass or a still pipe in applications like heavy foam build-up.
For more information about heavy foam build-up and turbulence, see Heavy foam build-
up and turbulence .
For more information about the minimum internal pipe diameter, see Installation in pipes .
For general installation instructions, see Installation .
3.5.3 Function check
After turning on the level transmitter, it is in operating mode. It measures and evaluates
level and generates output signals according to the set parameters.
Check that the level transmitter is operating correctly before using it in a production
environment.
3.5.4 Operation indication
These indicators show how the level transmitter is operating.
Indicator Definition
---- continuous Initialization phase after power on
Initially the level transmitter is not operational. Configure basic settings
to enable the level transmitter (see
Change basic settings ).
---- Level below the active zone
Numerical value + LED
1 Current level in millimeters
Numerical value + LED
2 Current level in inches
Numerical value + LED
3 Current level in percent of the scaled measuring range
LED 7 / LED 8 Switching status OUT2/OUT1
FULL + numerical value
alternately Level has reached or exceeded the maximum measuring range (=
overflow warning).
SIM + XXX Simulation active. XXX = state to be simulated (See Simulation )
S.On Simulation stopped (See Simulation )
