BEFORE YOU BEGIN
This manual has been prepared for OVAL flow computers of the EL4001 series. Making sure of your
model number and good understanding of the input/output and calculation process according to the
instruction manual for the model, refer only to the specific topics of interest.
In the EL4001 series, mode selection is simple with keystrokes on the front-panel keypad. However, we
recommend you to become thoroughly familiar with the procedure described in this manual before you
reconfigure parameters.
If you have something to inquire, contact the sales office from which you purchased the product, or the
nearest OVAL representative in our customer service network.
(When you inquire, please supply us with the product name, model No., serial No., and other pertinent
information.)

1. KEY ARRANGEMENT
1.1 Front Panel Part Names
1.2 Function Keys
In the EL4001 series, software-defined function keys are used: they have different functions as the user
moves from screen to screen. The four round keys located directly below the display are the functions
keys. The functions assigned to individual keys are indicated in the bottom line of each screen.
1.3 Arrow Keys
In the SET and SYS modes, the arrow keys are primarily used for moving the cursor (“▶”) (up and
down arrow keys) at a menu, for moving the cursor (highlighted) (left arrow and right arrow keys) at a
variable setup menu, and for increasing or decreasing the number pointed by the cursor (highlighted) (up
arrow and down arrow keys).
In the RUN mode, the up arrow and down arrow keys correspond to the“PAGE UP”and“PAGE
DOWN”. (In the RUN mode, the right arrow and left arrow keys are not used.)

3 . ABOUT INITIAL CHECKS
Each EL4001 series computer runs a series of initial performance checks at startup or power cycling. In
this initiation process, tests are performed on possible problems associated with CPU performance in the
computer, parameters and process variables stored in the memory, problems in the memories
themselves, and memory read/write.
The test items subject to the initial checks are:
1) Memories (data/hardware)
3.1 Memory (data/hardware) Check
←A screen during a memory check
In the initial check, a memory check covers both the hardware and data. Individual
memory check items appear sequentially.
3 1.1 RAM (work area) Hardware Check.
←A screen upon completion of a memory check
If found all right upon completion of a check, an“OK”appears. However, if errors
are found in certain (some) check items, corresponding error messages will
appear.
←A screen showing a memory check error
In the RAM (work area) check, proper read/write in and out of the memory is
verified. If an error condition is found in this check, an error message appears and
the CPU stops processing.
While this message appears, the CPU stops processing and does not accept any
command by keystrokes.
To restart, power cycling is required.

created at data writing is compared against the sumcheck data created from the
data currently stored in the memory. If an error is found during this check,
parameter configuration will be replaced with default settings.
After seeing this message, pressing the function key“OK”causes the data to go

※ With calibration data set in default, the temp, input, pressure input, and
analog output will not function properly. So be sure to make recalibration.
←A screen showing a memory check error
An E2PROM(parameter area) data check is performed if parameters remain

←A screen showing a memory check error
In an E2PROM (system config area) data check, whether or not the data stored in
the memory are free from any damage is verified. In this check, Sumcheck data
created at data writing is compared against the sumcheck data created from the
data currently stored in the memory. If an error is found during this check, model
config program will be cleared, bringing up an undefined status in the model
configuration.
After seeing this message, pressing the function key“OK”causes the data to be
cleared.

4. ABOUT MODE SELECTION
4.1 Mode Select Menu Screen
In the EL4001 series, the user can change from one mode to another at the mode select menu. From this
menu screen, he can select one of the available options, such as the RUN mode, SET mode, SYS mode,
EXTD mode, or 1C card support screen (a parameter setup card inserted).
By establishing a password for the SET mode, the computer can be configured to ask the user for a
password each time he attempts to change modes. This configuration will safeguard the computer
against inadvertent mode changes. (See the section on PASSWORD SETTING for the SET mode.)
※ Normally, the password setting is in the ON and at a default “1111”. If the user himself wants
to establish a new setting by changing modes, thoroughly read this manual before you start
working with it.
By selecting DIP switch settings, you can inhibit switching in the SET mode and SYS mode. In this case,
reconfiguration of settings in the SET mode and SYS mode remain disabled unless DIP switch settings
are in the OFF.

4.3.1 When Password Setting is ON
When the password setting is ON, some labels indicating the functions of function keys appear
highlighted. (About the password setting, see the section on PASSWORD SETTING for the SYS mode.)
If a new password that has just been entered proves to be unacceptable upon function key“ENTR”
depression, the following message will appear.
←Mode select menu screen
When the user attempts to switch to the SET mode or SYS mode from this status,
a screen asking the user for a password appears as shown below.
(Switching to the RUN mode does not raise this inquiry.)
←Password entry screen
Move the cursor with the left arrow and right arrow keys; increase or decrease the
numerical value with the up arrow and down arrow keys. When a desired
numerical value appears, establish it at the touch of the function key“ENTR”.
If the numerical value entered agrees with the value set in the SET mode,
switching to the mode desired takes place. If not, an error message appears as
shown below and the screen goes back to the mode select menu screen.
←Password entry error message
If the numerical value entered fails to agree with the value set in the SET mode, an
error message appears and the screen goes back to the mode select menu
screen.
