Introduction

This document describes the use of a 5024G LCD display terminal from Eilersen Electric,

when the software version listed on the front page is installed.

With this software, the terminal can perform automatic dosing (coarse/fine) using its digital

outputs and inputs. One digital output is used for coarse dosing and one digital output is

used for fine dosing, while a digital input is used for start of dosing and a digital input is used

for registration of dosed amount.

Installation

The following steps must be performed before the system is used:

•Install the load cells and check mechanical installation

•Optional: Connect digital outputs and digital inputs

•Connect and apply power

•Check software version

•Optional: Activation of Intelligent Setup feature

•Set up load cell configuration

•Power cycle the unit

•Configure weighing ranges

•Perform coarse taring

•Optional: Configure display, filtering, zero tracking range, stability requirement

•Optional: Corner calibration, system calibration, linearization

•Perform load check

Please notice: Perform a load check before the system is used to be sure that all require-

ments regarding accuracy, stability etc. are met before the system is used.

Please notice: If the Intelligent Setup feature is used, this will perform some of the subse-

quent points in the above list.

Details on the steps needed to install the system are explained below.

How to

–Perform basic operations

When the system is installed and power-up sequence has ended the display will look like this:

WWW.EILERSEN.COM

Weight reading:

•The actual weight reading is displayed in large types.

•To the right of the weight reading, the unit is indicated, like KG, LB etc.

•Below the unit gross/net selection is indicated with GROSS or NET.

•If an error condition is present the weight reading will indicate the error, like UL, OL,

- 0080 –etc. Please see below in section Trouble shooting, page 29 for details on er-

ror codes and how to recover from various error situations.

Status indications:

•‘>0<’ in the upper right corner status field indicates that the actual gross weight is ze-

ro (within ± ¼ division).

•‘--’in the second status field indicates that the weight reading is steady/stable. If the

reading is unstable ‘~’ will be indicated.

•‘ZT’ in the third status field indicates that a zero tracking device is active, holding the

actual gross weight at zero.

•‘SP’ in the fourth status field if automatic dosing is running.

‘R’ in the fourth status field if registration is in progress.

•Above the key the actual setpoint (fine limit) is shown.

•Above the

Clr

key the last registered weight is shown in parenthesis. Also above the

Clr

key an “OK” icon is shown for a short period following every successful registra-

tion.

Please notice: The net weight is used to determine the state of the digital outputs during

dosing even when the gross weight is displayed.

Please see below how automatic dosing and digital outputs are used.

Please notice: If none of the icons directly above the keys are visible as shown in the

screen shot above, the keyboard is locked, since the Keyboard unlock length parameter

in the SETUP SYSTEM screen has been activated. As long as the keyboard is locked, no

keyboard actions will be available. Please see below in section - Unlock the keyboard,

page 11 on how to unlock the keyboard.

Keys/actions:

Invoke the MAIN menu.

Select the DOSING screen to enter the setpoints and start/stop of dosing.

WWW.EILERSEN.COM

Displays weight with enhanced resolution for 3 seconds. The “Dd/10”symbol

above the key will flash when enhanced resolution is shown.

Switch between Gross and Net reading.

Not used.

Sets the net weight to zero and select Net reading.

>0<

Sets the gross weight to zero and select Gross reading.

–Perform automatic dosing

To perform an automatic dosing, follow this procedure:

1. The desired Coarse and Fine setpoints must be entered. Use the key in the NORMAL

screen to select the DOSING screen. Then use the DOSING screen to enter the desired

setpoints.

2. To start a new dosing select the “Action: START DOSING” using the or key in the

DOSING screen and then press the key. Alternately start a new dosing by activating

the digital START input.

3. This will zero the net weight (automatic tare) and activate the digital COARSE and FINE

dosing outputs.

4. During dosing the COARSE output is active as long as the net weight does not exceed the

COARSE limit. An active COARSE output indicates dosing should be done at high speed

for the first part of the dosing, followed by slow speed for the final part of the dosing

where the COARSE output is deactivated.

5. When the net weight (positive or negative) reaches the FINE setpoint (possibly adjusted

by the afterflow correction) the FINE output will be deactivated and dosing is stopped.

6. Hereafter the COARSE and FINE outputs will remain deactivated until a new dosing is

started.

7. The dosed amount is automatically registered after the entered registration period, if

the registration period is different from 0 ms. In this case a registration can be made by

activating the REGISTRATION input. The result of the last registration can be read in the

NORMAL screen.

8. Following a registration the totals are updated and a possible new afterflow correction

may be calculated.

9. An ongoing dosing can be stopped prior to reaching the setpoint, by selecting the “Ac-

tion: STOP DOSING” using the or key in the DOSING screen and then pressing the

key. An ongoing dosing is also aborted if the weighing range is exceeded or if a load

cell error occurs.

10. The weighing terminal is ready for start of a new dosing.

WWW.EILERSEN.COM

–Change setpoints for automatic dosing

In the MAIN screen press to select the DOSING screen, looking like this:

In this screen setpoints for dosing are shown and can be changed. It is also possible to

start/stop a dosing.

Keys/actions:

Select the previous setpoint/parameter.

Select the next setpoint/parameter.

Start entry of the selected setpoint or chooses the marked action.

Clr

Return to the MAIN previous screen.

Setting Coarse and Fine limits

The COARSE and FINE setpoints used for automatic dosing must be specified in the DOSING

screen.

The COARSE limit is used to control the COARSE output indicating high speed dosing until the

COARSE setpoint is reached. The FINE limit is used to control the FINE output indicating the

desired amount to be dosed. The setpoints are changed by using and to select the de-

sired setpoint (“Coarse” or “Fine”) with the cursor, and then pressing to request change

of the setpoint.

Start/Stop of dosing

In addition to starting a dosing using the digital START input, a dosing can be started (or

stopped if a dosing is already in progress) using the keyboard in the DOSING screen.

A dosing is started or stopped by using and to select the “Action” parameter with the

cursor, and then pressing to request the indicated action (“START DOSING” or “STOP DOS-

ING”).

Please notice: Some other dosing parameters (such as registration period and afterflow cor-

rection) are configured in the DOSING PAR. screen.

WWW.EILERSEN.COM

–Change dosing parameters

From the menu system the DOSING PARAMETERS screen is selected:

In this screen dosing parameters such as registration period and afterflow correction are

shown and can be changed.

Change registration period

The registration period is the time from a dosing has finished to the actual amount dosed is

registered automatically. The registration period is entered in milliseconds (0 - 30000 ms).

The value should be set large enough to ensure no vibrations and a stable weight indication is

achieved before the automatic registration is performed. A value of 0 ms indicates that NO

automatic registration is performed, and that a registration must be made using the REGIS-

TRATION input (or the keyboard).

Change afterflow status

The afterflow status indicates whether afterflow correction is disabled (OFF), enabled using a

fixed correction (ON) or enabled using an automatically adjusted correction (AUTO).

Change afterflow correction

The actual afterflow correction used during dosing if enabled using the “Afterflow status” pa-

rameter (ON or AUTO), is the amount prior to the net weight reaching the FINE limit, where

the dosing is assumed to be completed and the FINE and COARSE outputs are deactivated.

The “Afterflow” parameter indicates the actual correction.

Please notice: The “Afterflow” parameter is not used if afterflow correction is disabled by

setting the “Afterflow status” parameter to OFF.

Please notice: The “Afterflow” parameter can be changed automatically after each dosing if

afterflow correction is performed automatically by setting the “Afterflow status” parameter

to AUTO.

–Reading totals

In the MAIN screen

is pressed to select the TOTALS screen from the menu:

In this screen the totals are shown. Whenever a registration is performed the total weight is

updated with the registered amount and the total count is incremented.

Reset of totals

Totals are reset by pressing

to show the TOTALS menu, where the ”RESET TOTALS” item is

selected with the cursor using the and keys and then pressing the key.

Please notice: Reset of totals can NOT be undone.

–Operate the menu system

The installation and service of the system is operated by a series of menus and screens.
