this manual, particularly Section 2: Safety[»5].
4.1 INTRODUCTION
This chapter describes the daily use and operation of the E490-A-PL. For this, the unit is equipped
with a control panel that provides the operator with various functions, information and operating
modes.
4.1.1 OPERATING MODES
The following operating mode are available:
OPERATOR-mode
This is the default mode of operation and mode indicator
RUN
is shown on the display. This
mode is available for all operators and gives access to most other modes. The available
functions and rights depend on the type of unit and configured settings. The unit will always
return to this mode when there is no user interaction for some time in any of the other modes.
SETUP-mode
This mode allows to review all configuration settings using a SETUP-menu. The mode indicator
SETUP
is shown on the display and access can be restricted via a password. After selecting a
configuration item, it can be changed using the PROGRAM-mode.
PROGRAM-mode
This mode is used to change settings in the SETUP-menu, enter values in OPERATOR-mode or
enter a password. When a setting is being changed, this is indicated by the mode indicator
PROG
on the display.
The following paragraphs describe the modes of operation in more detail. SETUP-mode and
PROGRAM-mode are described in Section 5: Configuration[»14].
4.2 CONTROL PANEL
The control panel is located on the front side of the E-Series and consists of the following parts:
A Liquid Cristal Display (LCD) to show process values and various other information.
Three optical keys (PROG, SELECT, CLEAR) to control the unit during operation.
A backlight to illuminate the display.
When the front cover is removed (only during service in non-hazardous area), the following parts
also become available:
The Main Electronics Module (MEM)
Three mechanical keys to control the unit during service.
A switch to completely disable the optical keys.
These parts are explained in Section 5.2: Operating the Main Electronics Module (MEM)[»14].
Explosion risk: never open the housing when explosive atmosphere is present.
Opening and servicing of the unit may only be carried out by authorized and trained personnel who
have read and understood this manual, particularly Section 2: Safety[»5].
4.2.1 DISPLAY
Inside the E490-A-PL, the current loop input is continuously processed in the background. The
relevant process information is then displayed on a selection of screens when the unit is in
OPERATOR-mode.
Normally, the information shown on the display is updated 8 times per second. For improved
readability of quickly varying input signals, the displayed process values are only refreshed 1 time
per second.
The display contains one line with large digits at the top and one line with small digits at the bottom.
The top line is mainly used to display key process information, while the bottom line usually displays
measurement unit and less important information or system messages.
Symbols to indicate the operating mode are also available. The following image shows this in more
detail:

4. Key lock symbol (for optical keys) 8. Speedometer
4.2.2 OPTICAL KEYS
The optical keys are used to control the unit ‘through the glass’ without the need to open the
enclosure. To activate an optical key, position a finger (clean and without gloves) in front of the glass
above the indicated area for PROG, SELECT or CLEAR. Correct key operation will result in the
activation indicator to show on the display. After the indicator is shown, the finger can be
removed and the selected key ‘is pushed’.
The optical keys only work reliably when the glass is clean. Try to avoid actually touching the glass
as this could leave smudges. Clean the glass regularly with a lint free cloth dampened with (soapy)
water.
False activation or bad responses of the optical keys can also be caused by:
Dirt, grease or dust on the glass.
Shiny surfaces positioned up to 100 mm (4 inches) in front of the display.
Key lock function
To prevent any erroneous operations due to false optical key activation, a key lock function is
implemented. When the function is enabled (default), the optical keys are automatically locked if no
optical key is activated for 30 seconds.
False optical key activations can cause erroneous operation.
Therefore, it is advised to keep the key lock function enabled.
E490-A-PL
FW_E490-A-PL_M_v0302-03_EN Page 11
The Key lock symbol appears on the display to indicate that the keys are locked or disabled:
PROG SELECT CLEAR
Fig.5: Key lock symbol
To unlock the optical keys, an unlock sequence needs to be performed. Start the unlock sequence
by activating any of the optical keys for one second and then releasing it. The display will now
prompt the operator to activate each optical key in sequence: PROG > SELECT > CLEAR.
When successful, the Key lock symbol disappears and the optical keys can be used to control
the unit. To lock the optical keys again, wait for 30 seconds or push the PROG and CLEAR keys
simultaneously for 3 seconds.
(Temporarily) Disabled optical keys
To prevent unwanted access or operation, the optical keys can be disabled completely. Additionally,
after using the mechanical pushbuttons, the optical keys are automatically disabled for 30 seconds.
When the optical keys are disabled, the Key lock symbol is shown continuously and the display
does not prompt for the unlock sequence. See Section 5.2: Operating the Main Electronics Module
(MEM)[»14] for more information.
4.2.3 BACKLIGHT
The E490 is equipped with a backlight to illuminate the display for improved readability. Depending
on the type of supply and loop mode, the backlight functions as follows:
When the unit is powered by an external power supply, the backlight is on continuously and its
brightness is set by configuration setting
SETUP
2.5: DISPLAY > BACKLIGHT (BRIGHTNESS)[»20].
When the unit is only powered by the current loop, the backlight can still be used (see
Section 6.4.4: Current loop mode and backlight brightness[»33]). Its brightness is then fixed at a
reduced intensity and the configuration setting is used to turn the backlight on and off.
4.3 OPERATOR FUNCTIONS
Before operating the unit, check that the symbol is not shown on the display.
Otherwise, unlock the optical keys as described in Section 4.2.2: Optical keys[»10].
4.3.1 FUNCTIONS OF THE KEYS IN OPERATOR MODE
The following functions are available:
PROG-key
This key is used to gain access to SETUP mode, see Section 5: Configuration[»14].
SELECT-key
This key is used to select the displayed information, like actual measured input current
and percentage.
CLEAR-key
This key has no function in operator mode.

4.4 DISPLAYED INFORMATION
4.4.1 PROCESS VALUES
Main process value
The main screen shows the calculated process value on the top line with the specified number of
decimals as configured in
SETUP
1: VALUE[»19]. When “-----“ is indicated the calculated value is too
large to be displayed.
The engineering unit and optional time unit are indicated on the bottom line of the display. If there
isn’t enough room available, the display will toggle between unit and time unit.
Percentage value
The process value can also be displayed as a percentage between 0.0% and 100.0%.
In most cases, 0% will correspond with 4mA input current and 100% with 20mA. However, if a
reverse curve is selected in
SETUP
1.7: VALUE > REVERSE[»20] 0% will correspond with 20mA and 100%
with 4mA.
Actual loop current
The input loop current is measured and processed 4 times per second based on the settings of
SETUP
3: SENSOR[»20] and the result is then used to calculate the various process values.
The result is also used to calculate the actual loop current (in mA). This calculation omits any filter,
square root or reverse curve calculations and is always based on the factory calibration.
E490-A-PL
FW_E490-A-PL_M_v0302-03_EN Page 13
Speedometer
A speedometer view of the process value can be shown along the top edge of the display. It
contains 10 segments of 10% each, ranging from 0% to 100% and can be enabled and disabled in
SETUP
2.4: DISPLAY > BARGRAPH[»20].
4.4.2 PROCESS LIMITS
When indication of process limits is enabled in
SETUP
2.3: DISPLAY > LIMITS[»20], the operator can select
two additional screens that show the minimum (0%) and maximum (100%) limit of the main process
value.
4.5 OPERATOR ALARMS
4.5.1 RANGE ERROR
When the input current of the current loop is outside the valid measurement range (e.g. due to a wire
break or a faulty sensor), a range error is raised and the display indicates the status on the bottom
line as follows:
Input current Displayed value Status indication
Below 2.00mA - - - - - NO SIGNAL
2.00mA … 3.75mA 00000 RANGE ERROR
3.75mA … 4.00mA Value at 4mA -
4.00mA … 20.00mA Calculated value -
20.00mA … 22.00mA Value at 20mA -
Above 22.00mA 99999 RANGE ERROR
Note: The current loop input circuit is guaranteed to operate reliably from 3.3mA. Below this current, the shown
values are only an indication and at some point, the circuit will stop working.
4.5.2 INTERNAL ERROR
When an internal error occurs, the alarm flag starts flashing to indicate this.
If the alarm flag shows because of an internal error, the alarm code can be displayed by pushing the
SELECT-key repeatedly until the internal alarm screen is shown.
See Section B: Troubleshooting[»39] for a description of the codes.

You may be prompted to enter a password (do so as described in Section 5.3.3: Changing
configuration settings[»17]).
3. The
SETUP
indicator is now activated on the display and the
RUN
indicator is deactivated.
5.3.2 NAVIGATING THE SETUP MENU
The SETUP menu contains several menu groups, which each contain various menu items. Each
menu item has a unique number which is displayed below the
SETUP
indicator at the bottom of the
display. Additionally, each menu item is expressed with a keyword.
The menu number is a combination of two figures separated by a dot:
the first figure indicates the selected menu group (e.g. 1. TOTAL).
the second figure indicates the menu item (e.g. 1.1 UNIT).
The following image shows the layout of the menu structure:

Navigate the SETUP menu with the following functions:
PROG-key
When a menu item is selected (e.g. 1.1), this key is used to start the programming
sequence.
When a menu group is selected (and no function), this key is used to scroll back a
group (e.g. 3. à 2. à 1. à 3. à 2. ...)
SELECT-key
This key is used to select the next menu item in the list (e.g. 1. à 1.1 à 1.2 à 1.3 à
1. ...). When the top of the list is reached, it will wrap around and return to the menu
group selection.
CLEAR-key
This key is used to select the previous menu item in the list (e.g. 1.3 à 1.2 à 1.1 à 1.
à 2. ...). When the bottom the list is reached, it returns to the menu group selection.
When a menu group is selected (and no item), this key is used to scroll to the next
group (e.g. 1. à 2. à 3. à 1. à 2. ...)
5.3.3 CHANGING CONFIGURATION SETTINGS
A menu item either contains a value (a number with optionally a decimal point and sign, e.g.
-123.45), a selection list (e.g. L – m3 - USGAL) or a line of text (e.g. ABCDEFGH). After a menu item
is selected in the SETUP menu, a new value can be programmed by performing the following steps.
During the programming sequence, the
PROG
indicator is flashing on the display.
Step 1: Start the programming sequence:
PROG-key
When a menu item is selected in the SETUP menu, this key is used to start the
programming sequence.
Step 2a: Change a value
SELECT-key
This key is used to increment the selected digit or to select de next position of the
decimal point.
When the entered value is out of range, the increase sign or decrease-sign will
be displayed; the value will be automatically brought within range when confirmed later.
CLEAR-key
This key is used to select the next digit. If a decimal point can be set, this will be
included in the sequence as well (e.g. [decimal point] à digit 1 à digit 2 à digit 3 à
[decimal point].
The selected decimal point is flashing when is can be changed. When no decimal point
is selected, all available decimals will be flashing on the display to indicate this when
the sequence reaches the decimal point.
SELECT CLEAR
SELECT-key + CLEAR-key
The combination of the SELECT-key and CLEAR-key is used to select a negative
value. When a value can also be entered as a negative number, pressing the SELECT-
key and CLEAR-key simultaneously will toggle the ‘–‘ (minus) sign on and off.
Step 2b: Change the selection in a list
SELECT-key
This key is used to select the next item in the list (e.g. L àà USGAL).
At the end of the list, the selection will wrap around to the first selection.
CLEAR-key
This key is used to select the previous item in the list (e.g. USGAL àà L).
At the bottom of the list, the selection will wrap around to the last selection.
E490-A-PL
Page 18 FW_E490-A-PL_M_v0302-03_EN
Step 2c: Change a line of text
SELECT-key
This key is used to scroll though the list of available characters, which is determined by
the selected position on the display. If possible to display, the following characters can
be selected: ", *, , 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O,
P, Q, R, S, T, U, V, W, X, Y, Z.
When a line of text is programmed via the Remote Configuration Software, this will also
be restricted to the character set indicated above but some tweaking on the local
display might be required.
CLEAR-key
This key is used to select the next character. When the end of the line is reached, the
selection will wrap around to the first character (e.g. character 1 à character 2 à
character 3 à character 4 à character 1).
The currently selected character will be flashing; when the selected character
represents a space, it will alternate with an _ (underscore).
A blinking underscore _ represents a space, not an underscore!
Press the CLEAR-key for 3 seconds to clear the entire line of text.
Press the PROG-key for 3 seconds to cancel any changes.
Step 3: Finish the programming sequence
PROG-key
During the programming sequence, this key is used to confirm the new value and
return to SETUP mode. To cancel the operation, either press the PROG-key for 3
seconds or wait for 20 seconds: the programming sequence is cancelled and the
former value is reinstated.
5.3.4 RETURNING TO OPERATOR MODE
When all configuration settings are set correctly, return to OPERATOR mode by pressing the
PROG-key for three seconds, or do not press any key for 2 minutes to return automatically. The
RUN
indicator is now activated on the display and the
SETUP
indicator is deactivated.

When USER is selected, the user defined measurement unit set at
1.3: VALUE > USER is displayed.
When the measurement unit is altered, span and offset have to be
adapted as well; the calculation is not done automatically!
1.2 TIME This setting is used to select an optional time interval (sec, min, hour or
day) for the main process value. The following can be selected:
none (----), /sec, /s, /min, /m, /hour, /h, /day, /d, /xxx
If USER is selected at 1.1: VALUE > UNIT, the selected time unit overwrites
the last three characters of the user defined unit set at 1.3: VALUE > USER.
1.3 USER This setting is used to enter a user defined measuring unit of up to 8
characters long that will be shown on the bottom line of the display if
USER is selected at 1.1: VALUE > UNIT,
If a time unit is selected at 1.2: VALUE > TIME, the selected time unit
overwrites the last three characters. If /xxx is selected, only the ‘/‘
symbol is displayed.
Section : Changing configuration settings[»18] shows instructions on
changing the characters via the control panel. Alternatively, the
characters can also be programmed via the Remote Configuration Tool.
Please note that the first 2 characters on the left have a reduced
character set as compared to the other 6 characters.

1 VALUE
1.4 DECIMALS Determines the number of decimals used for displaying the main
process value.
The number of decimals selected here is also used for 1.5: VALUE > SPAN
and 1.6: VALUE > OFFSET.
1.5 SPAN The span is used to convert the sensor signal to a process value and
represents the difference between the maximum process limit (100%)
and the minimum process limit (0%). The span is entered in the range of
0 to 99999 while taking into account the configured number of decimals
of 1.4: VALUE > DECIMALS.
The accuracy of the measurement system depends on the accuracy of
the entered span and offset. When the accuracy of the main process
value is insufficient, a smaller measurement unit can be selected, or the
number of decimals increased.
1.6 OFFSET The offset is used to set the minimum limit (0%) of the process value.
The offset can be entered in the range of -99999 to 99999 while taking
into account the configured number of decimals of 1.4: VALUE > DECIMALS.
1.7 REVERSE Normally, the input loop current and the process value are directly
proportional. However, in cases where they are inversely proportional,
this direction can be reversed with this setting:
Off: the displayed value increases with increasing input current.
On: the displayed value decreases with increasing input current
5.5.2 MENU 2: DISPLAY
2 DISPLAY
2.1 CURRENT When this setting is set to on the actual measured input loop current
(mA) can be reviewed in operator-mode.
2.2 PERCENTAGE When this setting is set to on the process value displayed as a
percentage (%) can be reviewed in operator-mode.
2.3 LIMITS When this setting is set to on the minimum process limit (0%) and
maximum process limit (100%) can be reviewed in operator-mode.
2.4 BARGRAPH The unit has a speedometer/bar graph around the edge of the display
that gives a quick impression of the actual process value. The following
can be selected:
Enable: the bar graph is switched on.
Disable: the bar graph is switched off.
2.5 BACKLIGHT
(BRIGHTNESS)
The display is equipped with a backlight with adjustable brightness. This
setting allows the intensity to be adjusted in steps of 20% from off (0%)
to maximum (100%).
When the backlight is only supplied by the current loop, the brightness is
fixed on a reduced intensity, and can only be turned on and off.
5.5.3 MENU 3: SENSOR
3 SENSOR
3.1 FORMULA The E490-A-PL can process the analog signal with two different
formulas:
Interpolation: the signal is processed in a linear way
Input value (%) = 100% x Iscaled
Square root: the signal is processed for a quadratic relationship, e.g.
with differential pressure measurement for flow indication
Input value (%) = 100% x √Iscaled
Where Iscaled = measured analog input value, scaled between 0 and 1.
