3. MODIFICATIONS
Initial version.
4. INTRODUCTION
The electronic weight indicator model LD5208 is a compact micro-controller based unit specifically
designed for use on systems utilising strain gauge load cells.
The standard configuration includes:
1. High accuracy analog to digital converter (max 550.000 internal counts).
2. Front panel with 7 membrane keys with tactile feedback.
3. 6 digits, 7 segments, LCD display black (24 mm) plus annunciators.
4. Non volatile memory for system parameters and calibration data.
5. Serial port RS232C (COM1) for printing weighing data on a serial printer or host computer.
6. The microcontroller technology allows the instrument to perform in software all measuring
functions, operator input-output, automatic controls and sequences necessary for the
operation of weighing systems.
7. The setting of the unit is done through a guided keyboard operation, enabling the
adaptation to operating environment and system requirements.
8. A totaliser and counter is available that may be viewed or printed.
9. Several print formats are available selectable in setup.
10. A piece count facility, with selectable sample size, is available in the standard software.
11. Animal weighing with selectable number of samples is also included in the standard
software.
5. UNPACKING
Prior to unpacking the equipment, examine the carton for exterior shipping damage and if any
notify the carrier immediately.
Remove the equipment from the carton and plastic bag.
Inspect extent of supply for any sign of damage.
Save packaging material.
Verify that your indicator has been shipped with the following items :
Indicator LD5208 in plastic enclosure

6. INSTALLATION
6.1 Mounting location – Environmental considerations
The mounting location must be such that the instrument is not subject to excessive vibrations, heat
or humidity. Avoid direct sunlight on the front of the instrument. The unit has to be installed at the
right height to allow an easy reading of the display and convenient keyboard operation.
AMBIENT : Storage - 10 to +70 0C.
TEMPERATURE Operating -10 to +40 0C.
HUMIDITY : 40 to 90% RH (non condensing).
VIBRATION : Severe vibration can affect the accuracy of weighing and damage
electric / electronic components.
AIR : The surrounding air should be dust free and not contain any corrosive
gasses or materials which could adversely affect the equipment.
PROTECTION : IP40.
ELECTROMAGNETIC : Heavy electrical equipment should not be installed close to
FIELDS the weighing equipment.
INCOMING AND : Relays and contactors connected to the equipment must have
OUTGOING SIGNALS reliable and effective interference suppression. This also applies to other
equipment located within a distance of 3m from out equipment.
Cabling must be performed according to normal practice.
NOTES : - WELDING on or in the vicinity of the equipment is strictly prohibited.
- STATIC loads, caused by thunderstorms, have to be prevented from
developing by use of reliable lightning conductors.
- ENSURE that the cooling of the equipment is not obstructed.
6.2 Power
The instrument is powered from external power adaptor (9VDC/800mA) or internal battery.
Battery charging is performed while the external power supply is connected.
As the instrument is computer controlled it requires clean power for reliable operation.
Power supplied should come from a source that is isolated from other process equipment.
WARNING
Verify that the AC POWER SOCKET outlet is properly protected.
To avoid shock hazards, always be certain that the power adaptor is disconnected from the
wall outlet BEFORE opening the enclosure.
DO NOT USE any other type of power adaptor than the one supplied with the indicator.
DO NOT create a safety hazard by defeating the grounding feature.

7. FRONT PANEL SURVEY
7.1 Weight display
The indicator LD5208 has a 6-digit display for the indication of:
measured weight (gross or net)
error messages
other messages indicating the status of the scale
user guidance for the settings of the scale and the selection of operations
technician guidance for the configuration and calibration procedures and checking purposes
7.2 Status annunciators
At the left and right side of the digits small messages, called STATUS ANNUNCIATORS, appear in
order to provide status information during the weighing process.
O It is illuminated when the scale is stable.
ZERO It is illuminated when the scale weight is stable and within 1/4 division of actual zero.
TARE It indicates that a tare value is being displayed.
NET It is illuminated when the scale has been tared and the display is in NET mode.
pcs It is illuminated when pieces are displayed.
b It lights up steady when the battery charge is being displayed. It flashes when the battery
charge is below 20% of the scale capacity.
ob Battery charge indicator (under the display). Red colour: charging.
Green colour: charging completed.

7.3 Front panel keys
! POWER ON-OFF KEY
-By pressing momentarily the unit turns on and initiates power on self-test.
-By pressing again momentarily the unit turns off.
) ZERO / CLEAR ERROR/ESCAPE KEY
-It is used to reset the weight display to zero. Zeroing will be effective only if the
scale is stable, in gross mode, and the weight is within + 2% of max weighing capacity.
-If an error is present on the display press this key to acknowledge.
> NET / FUNCTION KEY / MOVE ONE DIGIT (Move left and right)
-It is used to tare the scale. Taring will be effective only if the scale is stable and within
the max weighing capacity.
-If the scale has already been tared pressing of the key will cause the tare to be
cancelled and the weight display to return to Gross mode.
- During an entry pressing this key will move the blinking cursor one digit to the right.
-If the key is kept pressed for more than 3 sec the function menu is entered.
When the display shows Fn 00, press ( to return to weight display or type in the function
code desired in order to select a function. The function menu is used to activate a number
of software utilities. Refer to FUNCTION MENU, chapter 9 for details.
~ TARE RECALL KEY / PRESET TARE / INCREMENT FLASHING DIGIT
In Net mode only : Pressing this key will cause the tare memory to be displayed briefly.
In Gross mode: This key is also used for entering a preset tare via the keyboard.
The display shows PtAre and then 0 0 0 0 0 . Use the > and ~ keys to enter the desired
tare and press P to proceed or press ) to abort. When P is pressed the tare keyed in will
be automatically in effect and the weight display will turn to Net mode. To be accepted the
tare value must be within the weighing range. The preset tare will be lost in power down.
( PRINT / ACCUMULATE KEY / ACCEPT ENTRY
It is used to transmit weight data to peripheral devices via the serial port.
The transmitted weight will also be accumulated. The weight will be printed only if it is
stable and within the weighing range of the indicator.
Printing/accumulation will take place if enabled in setup (SETUP 1.1=1 and SETUP 2.t ≠ 00)
- In the Animal Weigh mode the preselected number of samples will be count down,
averaged and displayed / printed / accumulated. (if enabled in SETUP 4.A≠00)
< TOTAL / BATTERY CHARGE KEY / SCROLL KEY (Move up and down)
It is used to display the current accumulated total (activated only if SETUP 1.1=1).
Press < again to see the number of weighings.
Press < again to end the total display or
Press ( to print/delete the total.
If the key is pressed for more than 5 sec the battery charge in % of capacity is displayed.
Press Y again to end battery charge indication.
& PIECE COUNTING KEY
The key toggles between weight mode or piece counting mode
