WARRANTY Commissioning and Set-up Examples We guarantee this instrument against faulty workmanship and material for a period of one year from the date of delivery. The company undertakes to repair, free of charge, ex-works any instrument found to be defective within the specified period provided the Instrument has been used within the specification in accordance with these instructions and has not been misused in any way.
D-CAL CONFIGURATOR MANUAL CONTENTS Commissioning and Set-up Examples How to change the engineering units. Warranty, Contents ......................... 1 - 2 Document Conventions ......................... 3 - 4 Specification ......................... 5 Installation ......................... 6 Press [CHANGE] The display will flash the next available unit, press change until, Bar is displayed, press and hold select for two seconds to save the new units.
{ACCESS 2} DOCUMENT CONVENTIONS This manual uses the following typographical conventions to describe the functionality of the transmitter. The blind instrument has two buttons, marked ZERO and SPAN. The D-CAL has two buttons, marked SELECT (SAVE) and CHANGE {ACCESS 2}[SELECT] Once select is pressed the state of the password is shown either enabled or disabled press [CHANGE] until the desired state is shown.
{ACCESS 2} DOCUMENT CONVENTIONS READ THIS SECTION BEFORE ENABLING THE PASSWORD When commands are described in this manual, a set format is followed. At the top of the page, the access level is shown, e.g. {ACCESS2} {PASSWORD}[SELECT] The password function controls access to the menu levels of the transmitter. It acts only on the local D_CAL configurator, but can be turned on or off both locally and remotely.
LOCAL DISPLAY PERFORMANCE SPECIFICATION :The local display / configurator is not connected via the signal loop, but accesses the micro processor directly. This allows the unit to display a digital representation of the measured variables and settings without the inaccuracies or loop loading or an analogue meter.
{ACCESS 2} LOCAL CONFIGURATOR INSTALLATION & WIRING L CAUTION The FIXLOOP and trim functions are used to remove any differences between calibration and site current standards. The electronics generates and monitors the output current continuously but variations in site standards may require the output gain and zero to be trimmed. The FIXLOOP command may also be used to calibrate other instruments and controllers within the loop, by controlling the current within the loop .

Commands and HART Numbers used by 2HT {ACCESS 2} The (TRIMxxx) functions are used to trim the Lower and Upper Range Values of the analogue to digital converter (ADC) to an accurately generated, external pressure standard. This is used if the instrument is found to differ from the site standard, for whatever reason. The command can also be used to increase the measurement accuracy of a turned down instrument.
Configuration using the Local Display View Access 1 Access 2 Please Note :- This menu option is an unprotected level, most of the internal parameters can be viewed using this selection but no changes can be made. Intended for recording and logging instrument set-ups. This is a protected option; a password may be set if required to restrict access to the choices within this section. The passwords are set and enabled within {ACCESS 2}.
CONFIGURATION USING THE D-CAL {ACCESS 1} {SELFTEST}[SELECT] If you suspect the functionality of the transmitter, SELFTEST when passed will give a very high confidence level of the transmitters output, this is an extension of the tests that the unit performs on itself at all times. The screen will blank, test the display, memory, etc. and if all tests pass the unit will respond {MEM OK}, if a test fails the results will be shown on the screen. [SELECT] To return to the {SELFTEST} menu.
{ACCESS 1} DISPLAY MONITOR and VIEW MONITOR PV LOOP CURRENT SENSOR TEMP % OUTPUT {TAG}[SELECT] An eight character alphanumeric field for identification e.g. {TANK6} {LEVEL9} Monitor mode is the default of the display, it shows prime variable, loop current and sensor temperature. Prime variable is always displayed, cycling between value and engineering units, this is to allow engineering units to be shown without scrolling the display.
(Nb There is no Page 18) SELECT CHANGE {ACCESS 1} ACCESS 1 {OUTPUT}[SELECT] INPUT The transmitter’s analogue output and percentage display may be linear or square root, selected by this function. The PV display of engineering units is linear at all times. There is no facility for displaying engineering units of flow. If this is required, then a separate Flow Computer should be used.
{VIEW} The view menu is not protected by a password, as no changes can be made from within this menu option. After five minutes it will return to the monitor mode.
{ACCESS 1} {VIEW} {OUTPUT} {INPUT} [SELECT] continued This shows the function that is applied to the analogue output. The options are {LINEAR} AND {SQ ROOT} {DAMPING}[SELECT] {TRANSMTR} [SELECT] Enter the Transmitter menu The damping command is used to slow the rate of change of the output signal, it modifies both the analogue and digital signal. {ADDRESS} [SELECT] Shows the polling address of the instrument, 0 for point to point, 1-15 for multi-drop.
{ACCESS 1} {ACCESS 1} {INPUT} [SELECT] {INPUT} continued {RANGEHI}[SELECT] {PV UNITS}[SELECT] Because the measured pressure is converted to a digital number the way the number is displayed can be scaled to represent different engineering units, this affects the digital and local display signals. This is the pressure represented by 20 mA and may be less than range low to achieve reverse action of the analogue output.
