How to change the engineering units.

Objective:- Change the engineering units from the default, pascals, to Bar.

From Monitor mode:Press [CHANGE] the transmitter will display {VIEW} Press [CHANGE] {ACCESS 1} Press [SELECT] {INPUT} Press [SELECT] {PV UNITS} Press [SELECT] {Pascal}

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. All engineering units will be displayed with the new selection.

How to set the range of a 0 to 10 Bar instrument.

Objective:- Re-range the transmitter 0 to 3 Bar, without reference to a pressure source

From Monitor mode:Press [CHANGE] the transmitter will display {VIEW} Press [CHANGE] {ACCESS 1} Press [SELECT] {INPUT} Press [SELECT] {PV UNITS} Press [CHANGE] {RANGEHI} Press [SELECT] {10.000 BAR}

Press [CHANGE] The display will clear, the first character will flash. The new URV can now be set to three bar, the value is entered in the selected engineering units.

Use the change and sel ect keys to enter the value, select the sign first, ( + ), then repeatedly press change until the desired character is displayed, ( 3 ), select it, repeatedly press change until the decimal point character is shown, ( o ), select it, repeatedly press select until the last character is flashing, when select is pressed the whole display will flash, press and hold select for two seconds to save the new value. The URV of the transmitter is now set to 3.0 Bar, the instrument will output 20 mA for an input pressure of 3.0 Bar. If the instrument is re-ranged with reference to a pressure source, the digital display may need to be trimmed using TRIM URV, TRIM LRV to match a site pressure standard. This can improve the accuracy at large turndowns; the accuracy of the pressure source used for reference must be considered.

The first character will be flashing, use the change and select keys to enter the password

number you require. When the last character is set the display will flash.

There are now two options :-

[SELECT] Press briefly to abort and return to the {ACCESS 1} menu. [[SELECT]] Press and hold to save the new code.

{ACCESS 2}

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

Convention Description Function

[ZERO] [SPAN] Bold and bracketed

The screen will respond with {SAVED}

{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.

There are now two options :-

[SELECT] To abort and return to the {ACCESS 2} menu. [[SELECT]] Used to save the new state.

When {SAVED} is displayed press [SELECT] to return to {ACCESS 2}.

Once the access level has been enabled the password can be checked or changed.

From {PASSWORD}{ACCESS 2} :-

When {SAVED} is displayed press [SELECT] to return to {ACCESS 1}.

{ACCESS 2}

DOCUMENT CONVENTIONS

READ THIS SECTION BEFORE ENABLING THE PASSWORD

{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. It is assumed that where the transmitter forms part of an extended HART® system, that the system itself or local site disciplines will ensure that only authorised operatives gain access. If changes are made in a restricted menu, the transmitter will auto matically abort to monitor mode after 5 minutes. The transmitter is shipped with the passwords set to 1111 and 2222 respectively, but not enabled. If the numbers are changed and not recorded there is no way access can be gained. If this happens Delta can supply a unique secondary ACCESS 2 code.

{ACCESS 1}[SELECT]

Once select is pressed the state of the password is shown either enabled or disabled. Press [CHANGE] until the desired state is shown.

There are now two options :-

[SELECT] Press briefly to abort and return to the {ACCESS 1} menu. [[SELECT] ] Press and hold to save the new state.

When {SAVED} is displayed press [SELECT] to return to {ACCESS 1}.

Once the access level has been enabled the password can be checked or changed.

From {PASSWORD}{ACCESS 1} :-

[SELECT]{ENABLED}[SELECT]{1111} The first character will be flashing, use the change and select keys to enter the password number you require. When the last character is set the display will flash.

There are now two options :[SELECT] To abort and return to the {ACCESS 1} menu.

[[SELECT]] Used to save the new code.

When {SAVED} is displayed press [SELECT] to return to {ACCESS 1}.

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}

What you see on the screen is shown in “curly” brackets, e.g. {RANGEHI}, followed by a short explanation of the commands functionality or special points to note.

You then press [SELECT], [CHANGE] or [[SELECT]] as required - see page 4.

The manual explains the edits or changes that can be made, and how to return to the menu .

If you get lost within the menu system the layout on page 12 - 13 gives a full over view.

Please note :- After 5 minutes the display returns to monitor mode automatically.

Display and Edit Functions

All commands and functions are displayed as eight characters for clarity. Where messages, descriptions or values with engineering units are shown that require more than eight characters, the display will scroll or toggle.

Once a menu options value is displayed and the change button pressed, edit mode is activated.

There are four forms of editing, used for different functions :-

1. Template, Used for {TRIMLOOP}

2. Scrolling, Used to enter values that are longer than the display {DESCRIPT}

3. Text, Used to edit the text strings and messages that fit on screen {TAG}

4. Choice, enable \ disable, Used for turning functions on and off {SHOWHART}

All of these edits used the change and select keys in th e same way, change to cycle the digits to the one you want, select to move to the next character, when the display flashes [[SELECT]] to save, [SELECT] to abort.
