Eliwell EM300, EM300LX User Manual

USER INTERFACE

The user has a display and four buttons
for controlling instrument status and pro­gramming.

BUTTONS AND MENUS ACCESSING

AND USING MENUS

The resources are arranged in a menu that
can be accessed by pressing and quickly
releasing the “set” button (Machine Status
menu) or holding down the “set” button
for more than 5 seconds (Programming
menu). To access the contents of each
folder indicated by the relevant label, just
press the “set” button once. You can now
scroll through the contents of each folder,
modify it or use its functions. If you do
not use the keyboard for over 15 seconds
(time-out) or if you press the “fnc” button
once, the last value shown on the display
is confirmed and you return to the previ­ous screen mask.

MACHINE STATUS MENU

HOW TO LOCK THE KEYBOARD

Keyboard operating can be locked by pro­gramming the “Loc” parameter (see folder
with “diS” table). If the keyboard is locked
you can only access the Programming
MENU (see) Functions CANNOT be activat­ed with buttons (to silence alarms, for
example).

TELEVIS SYSTEM (LX MODELS ONLY)

The Televis remote control systems can be
connected using the TTL serial port.
The TTL- RS 485 interface module must be
used:

• 130 or 150 BUS ADAPTER.

• 350 BUS ADAPTER for EM300(LX) with
V/I. Pt100/TC input.

To configure the instrument to do this, you
need to access the folder with the “Add”
label and use the “dEA” and “FAA” para­meters.

USING COPY CARD (LX MODELS ONLY)

The Copy Card is an accessory connected to
the TTL serial port used for quick programming
of the unit parameters (upload and download
parameter map to one or more units of the
same type). Operations are described below:

Fr-Format

This command is used to format the copy card.
This is necessary if

•it is used for the first time,

•it is used with models that are incompatible,

•after use with a specific model, another model
must be connected.
Warning: when the copy card has been programmed
using the “Fr” parameter all the data entered is can­celled. This operation cannot be undone.

UL-Upload

This operation unloads the programming para­meters from the instrument.

dL-Download

This operation downloads the programming
parameters to the instrument.

NOTE:

• UPLOAD: instrument —> Copy Card

• DOWNLOAD: Copy Card —> instrument.

The operations are performed by accessing the
folder identified by the “FPr” label and selecting
the “UL”, “dL” or “Fr” commands. The operation
is confirmed by pressing the “set” button. If the

operation is successful, a “y” is displayed where­as if it is unsuccessful an “n” will be displayed.

Download “from reset”

Connect the copy card with the instrument OFF.
When the instrument is switched on the pro­gramming parameters will be downloaded into
the copy card; when the lamp test has been
completed, the following appear on the display
for about 5 seconds:

• label dLY if copy operation is successful

• label DLn if operation fails
PLEASE NOTE:

• after downloading the instrument will work
with the parameter map settings that have just
been downloaded.

PROGRAMMING MENU
(See Programming Menu Diagram)

1) Displaying level 1 parameters

To access the Programming menu, hold
the “set” button for more than 5 seconds.

Level 1 parameters can be protected by a
PASSWORD* (defined by parameter
DIS/PA1) If the PASSWORD is enabled, the
label “PA1” will appear when you access
the Programming Menu; press the “set”
button and the value “0” will appear; enter
the password using the “UP”/”DOWN” but­tons and press the “set” button again. This

allows you to access the level 1 parame­ters. Use the “UP” and “DOWN” buttons
to scroll through the other folders; the

folders will only display level 1 parame­ters.
PLEASE NOTE: It is strongly recommended

that the unit is switched off and on again
each time parameter configuration is
changed in order to prevent malfunction­ing of the configuration and/or ongoing
timings (compulsory for selection of

probe type and count parameters).

*PASSWORD

The “PA1” password allows level 1 and
level 2 parameters to be accessed. This
password is not present in the standard
configuration. To enable it (value ≠0) and
assign it the desired value, access the
Programming menu in the “diS” folder.
If the password is enabled, it will be
requested when entering the
“Programming” menu.

The alarm condition is always signalled by a

buzzer (if present) and the alarm icon LED

(IF PRESENT)

The alarm signal from the

• control probe that measures values outside
the nominal reading range

• control probe faulty/shorted/open probe for
4…20 mA* model appears directly on the instru­ment display as E1. Note: to prevent false
alarms, the error condition must persist for
more than 10 seconds.
An error condition in probe 1 (regulation) leads
to:

• E1 code appearing on display

PLEASE NOTE: In case of wrong connection of
the 3rd wire (Pt100 sensor) in “AL” folder it will
appear the label “Pt3”.
For few seconds the display will shows a uncor­rect temperature.

MAXIMUM AND MINIMUM TEMPERATURE
ALARM

If an alarm condition occurs and alarm exclu­sion times are not in progress (see alarm exclu­sion parameters), the fixed alarm icon comes
on.

Alarm table

Alarms are considered as absolute values This alarm
condition can be viewed in the “AL” folder with labels
“AH1-AL1”.

The maximum temperature alarm occurs when the
probe temperature is:

•higher than or equal to HAL/HA1

The minimum temperature alarm occurs when the
probe temperature is lower than or equal to LAL/LA1

The maximum temperature alarm back swing occurs
when the probe temperature is:

• higher than or equal to HAL/HA1 - AFd

Minimum temperature alarm back swing occurs when
the probe temperature is:

•higher than or equal to LAL/LA1 + AFd
