Field Configurators HARTConf, LHPConf for Transmitters with HART or LHP Communication and HART-USB Modem
4.2.5 Menu control
In the menu you can scroll by using directional pushbuttons;
the pushbutton OK is used for confirmation or entry to the
following level; the left arrow button is used for exit. The right
arrow button is used for displaying long character chains.
The HARTConf configurator can work in two operating modes -
Configurator and HART Modem. The operating mode is chosen
in the menu „Selection“ in the item „Operating mode“.
In the Configurator mode, the USB interface is used for
recharging only. In the HART Modem operating mode, one can
communicate with the connected instruments only when the
USB interface is connected to the PC by means of suitable
communication software (not included in the HARTConf
delivery).
4.2.6 Menu items
Information
A set of parameters identifying the connected instrument.
Variables
Reading and showing momentary values of max. four input
quantities (measured or calculated), output current, and
percentage of the range. By pressing the OK button during the
display, the size of the figure displayed is doubled.
Configuration
Menu for changing parameters of connected instrument.
* Configuration | Lower RV | Enter Value
* Configuration | Upper RV | Enter Value
This selection enable to change a preset range by entering
a value. The value editor makes it possible to enter any positive
or negative number. The up and down arrows keys set a number
value or the decimal point position. The right or left arrows keys
change the momentary set position. One can leave the editor
mode just by pressing the OK push button. A set value is stored
only when confirmed by the user. A change in the range is not
carried out when it is outside the maximum range limits, when
the instrument is in the setting protection mode, or when the
connected instrument does not support this command.
* Configuration | Lower RV | Apply Value
* Configuration | Upper RV | Apply Value
This selection enables one to set the beginning or end of the
range to the momentary input value. When the input quantity is
connected to the input of the instrument and stabilised, carry
out the „Apply Value“ command and acknowledge the assuring
question. A change in the range is not carried out when it is
outside the maximum range limits, when the instrument is in
the setting protection mode, or when the connected instrument
does not support this command.
Service
Menu of service functions.
Warning!
These functions are intended for advanced
users only because they can cause a permanent
change in parameters or adversely affect the calibration
of the connected instrument.
* Service | Fixed Output
It carries out output current loop test by the selected current.
After the current value is set and confirmed, the output of
connected instrument is adjusted to the required value.
Caution!
A control loop, as the case may be, must be
switched to manual operation in advance!
* Service | Sensor Zeroing
It carries out a sensor zero trimming to the momentary input
value. This adjustment is used particularly in differential pressure
sensors after their installation. This zero setting eliminates an
error caused by the sensor position, static pressure, etc. The
zero setting is not performed in case the input value is outside
maximum limits for zero setting, the instrument is in the setting
protection mode or when the connected instrument does not
support this command.
Caution!
The zero setting of an absolute pressure
sensor can result in permanent damage to the
instrument adjustment!
* Service | Trim DAC Zero
* Service | Trim DAC Gain
The configurator trims the start and gain of the D/A converter
for the conversion of the digital value of the output current to
real output current. Accurate performance of this operation
requires measuring the output current with at least 0.01%
accuracy.
* Service | Polling Addr.
To each HART instrument is assigned an address within the
0 - 15 range. The standard factory setting is 0. Addresses 1
– 15 are used in the Multi-Drop mode, which results in the
output current setting at 4 mA. After a change in address, one
must adjust the mode of connection initialisation in the menu
Options | Initialization.
* Service | Device reset
It shall RESET the processor of the connected instrument.
Execution of this command does not change any configuration
parameter, and temporary functions are cancelled. In principle,
it is equivalent to the disconnection of supply voltage of the
connected instrument with its subsequent reconnection.
* Service | Device test
It shall carry out a software test of the instrument. The test
result is available in the form of error reports. In case no
error reports show up, the test has identified no defects. The
configurator does not provide more detailed results of the test.
* Service | Burst
This command switches on a burst mode. In this mode, the
instrument continuously sends out a command set in “Service
| Burst Cmd” without being asked to. In the burst mode, one
