Radar Transmitter
2.6 Configuring the Transmitter
The Radar transmitter comes factory-calibrated and can be
configured in minutes for specific applications.
Before configuring the transmitter, collect the operating
parameters information. Then, power-up the transmitter
on the bench and follow through the step-by-step proce-
dures for the menu-driven transmitter display. Information
on configuring the transmitter using a HART communica-
tor is given in Configuration Using HART (Section 2.7).
2.6.1 Operating Parameters
Some key information is needed to configure the Radar
transmitter. If necessary, complete the configuration infor-
mation table in Section 1.1.2.
2.6.2 Setting Up for Shop Configuration
The Radar transmitter can be configured at a test bench by
connecting a 24 VDC power supply directly to the trans-
mitter terminals. The connections are illustrated in the
accompanying diagrams. An optional digital multimeter is
shown if current measurements are desired.
NOTE: Current measurements taken at these test points is an approx-
imate value. Accurate current readings should be taken with
the digital multimeter in series with the loop.
1. When using a HART communicator for configuration, a
minimum 250
Ω
line load resistance is required. See the
HART communicator manual for more information.
2. The transmitter can be configured without the antenna,
but disregard error messages due to the unattached antenna.
Radar transmitter may indicate a LEVEL value >0 when
disconnected from antenna.
2.6.3 Transmitter Display and Keypad
The Radar transmitter has a liquid-crystal display (LCD)
capable of showing two lines of 8 characters each.
Transmitter measurements and configuration menu screens
are shown on the LCD.
The transmitter default display is the measurement screen.
It cycles every 5 seconds to display LEVEL, %OUTPUT,
QUALITY, and LOOP information. The transmitter
defaults to this display after 5 minutes if no keystrokes are
sensed with the exception of LEVEL, DISTANCE,
%OUTPUT, QUALITY, and LOOP screens. The display
will not return to the default screen if left in one of these
screens.
