1. INTRODUCTION
FDT is a Remote Display Terminal specifically designed for use as remote weight indicator for
Digital Junction Box weigh systems (FAD-1 or FAD-4).
The unit maybe operated in the Master mode where it will poll all (max 30) FAD’s connected to it,
or in the Slave mode where it will only display information from a selected FA D.
Setup and Calibration of FAD’s is performed via FDT in the Master mode.
When several (max 30) FAD’s and FDT’s are connected on one cable, only one FDT is allowed to
poll the FAD’s. Communication in a master/slave network is based on LESIP serial interface protocol.
The unit may also be used as remote display for numeric indicators with continuous weight output
mode (LECW _ 2 format).
FDT may be used for legal for trade app lications when connected with one or more weigh scales,
since calibration data is stored in th e FAD.
The basic configuration VERSION A includes:
1. Serial port RS485A with network capability.
2. Front panel with 6 digit LED display plus 5 annunciators and 6 membrane keys.
3. Non volatile memory for system parameters and calibration data.
4. The setting of the unit is done through a guided keyboard operation, enabling the adaptation
to operating environment and system requirements. Two setup procedures are executed. Fn 49
for calibrating the FAD and Fn 4 6 for settin g up op eration mode and communication parameters
of FDT.
The advanced configu r ation (VERSION B) includes additionally:
1. Real time clock calendar with rechargeable battery backup.
2. Serial port RS232 adapter for printing weighing data on a serial printer and /or
bidirectional communication with a host computer.
3. Non volatile memory for storage of 10.000 weights.(Electronic tally roll or Alibi memory).
OPTIONS
OP.5 230 VAC to 9 VAC/ 500mA, mains power adapter.
OP.7 RS232C/RS485A converter including power adapter 230 VAC to 8 VAC/ 500mA.
OP.8 Bracket (Table top Wall mount) for the p anel version.
OP.9 Custom software on request.
ENCLOSURES
P Panel mount 72 x 144 x 70 mm
S Stainless steel 180 x 108 x 60 mm.
EXTENT OF SUPPLY
The standard supply includes:
The connection plug for the communication cable. The reference manual.
Prior to unpacking the equipment, examine the carton for exterior shipping damage.
If any notify the carrier immediately. Remove the equipment from the carton and plastic bag.

It indicates that a tare value is being displayed.
4. NO MOTION INDICATOR
It lights up when the scale is stable.

It lights up when the scale weight is stable and within 1/4 division of actual zero.
6. SCALE A INDICATOR
In ‘ dual scale mode’ it indicates the weigh t from scale A is displayed.
ON = Scale A is displayed OFF = Scale B is displayed
7. SCALE B INDICATOR
In ‘dual scale mode’ it indicates the weight from scale B is displayed.

8. 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 +
- If an error is present on the display press this key to acknowledge.
9. TARE KEY (toggle)
- It is used to tare the scale. Taring will be effective only if the scale is stable and
within the weighing capacity.
- If the scale has already been tared depression of the key will cause the tare to be
cancelled and the weight display to return to Gross mode.
10. TARE RECALL KEY
- Pressing this key will cause the tare memory to be displayed briefly.
- In “DUAL SCALE” mode the key switches between scale A or scale B or SUM (A+B).
11. PRINT – ACCUMULATE
It is used to transmit weight data to periph eral devices via the serial port 1.
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 and / or accumulation will take place only if enabled in set up.
The weight data printed is selectable in SET UP 2. 2t. Refer to the technical manual
for details.
12. TOTAL KEY
It is used to display the current accumulated total.
Press again to see the number of weighings.
Press again to end the total display or
Press to print/delete the total.
13. FUNCTION KEY
Enables a selection of software utilities 00 – 99.
Fn 00 appears on the display. Use keys to increment the flashing digit, to change digit.
When the correct number is displayed press . The selected function will be activated.
Refer to chapter 6 Fun ction menu for details of available utilities.

3. INSTALLATION
3.1. Mounting
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 keyboard
operation.
3.2 Wiring
Use 4 x 0,34 mm
for RS485A connection.
PANEL MOUNT
All connections to the instru men t are mad e through the rear panel connector. Strain reliefs are supplied
with the connectors. See connector diagram in Annex A .
STAINLESS STEEL
-Remove the rear panel by undoing the 4 screws. Lift the rear panel carefully.
-Insert cables via the cable glands. Strip and connect the power leads to J1, the RS485 leads
to J2 and RS232 leads to J3. (See connector diagram in Annex A). Connect the shields
of the cables on the ground tag provided.
-Re-install the rear panel. Tighten the screws until the rear panel touches the front panel.
-Tighten the strain relief’s to ensure a firm grip on the cables.
3.3. Power
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.
A main adapter of 7,5 – 10 VAC / 500 mA is recommended for operation of both the FDT and FAD-4.
3.4 Power up
When the unit is powered up it goes through a series of self tests after which the following
is displayed in sequence.
- Version code
- Revision date
- All display segment are turned on then off for 1 sec. Then it goes into the
operating mode. If an error is encountered it will be displayed in the form E xx .
Refer to chapter 7 Errors for details.
CAUTION : Do not run signal cables together with power cables.
2
screened for RS232C connection and 2x0,34 mm2 twisted pair and shielded
Connect the shielding where indicated on the drawing only.
Never use a meg ger to check wiring.
Be sure the AC power socket outlet is properly protected.
For optim um EMC performance, keep the length of shield inside the
enclosure as short as possible.

4. OPERATING MODES
FDT may be configured accordin g to the applications, to be operated in 4 different modes.
4.1 REMOTE DISPLAY - CONTINUOUS WEIGHT INPUT
The unit displays information received from the serial port(s) according to LECW_2 format
(P + 123.45 “CR”). RS485A may be received from port 1 (Version A or B). Baudrate and data
bits are programmable in SETUP 3.
RS232C may be received from port 2 (Version B only). Baudrate is fixed at 1200 baud. No or
even parity and 7 or 8 data bits are programmable in SETUP 2. 20 mA , current loop passive may
be connected to the RS232 port (Tx+ to Tx and Tx– to Rx).
SET UP REQUIREMENTS (Port 1 9600, E, 7, 1 or Port 2 1200, E, 7, 1)
1 Don’t care
2 2d = 17, the rest set to Zero
3 3t = 01, 3b = 96, 3d = 17
Upon power up a search is performed by the unit for input data from each serial port. If data is
input from port 1 it will be displayed. Else it will search port 2. If no data is received by any
port E30 will be disp layed until data reception is restored.
DO NOT CONNECT BOTH PORTS SIMULTANEOUSLY.
4.2 MASTER DISPLAY & KEYBOARD FOR FAD(S)
In this mode of operation the FDT polls the FAD(s) and displays their data. Commands such as
“Zero”, “Tare” etc. are issued to the FAD via the FDT’s keyboard.
Calibration of the FAD is also possible through a dialogue in the FDT. A number of FADs may be
connected in a network with one FDT acting as the master. The FAD address whose data is
displayed, is keyboard selected with Fn 01 to Fn 30 corresponding to FAD A to ^.
The default address is A ie the first FAD in the network.
SETUP REQUIREMENTS (9600, E, 7, 1, FAD address A, Nr of FADs = 4)
1 Application dependent
2 Application dependent
3 3t = 02, 3b = 96, 3d = 17, 3.n = 4, 3E = 65.
4
The F DT always polls FADs in seq uen ce, starting from address A and increments the add ress until
the programmed number of F ADs (set up 3 .n) where it circles back to A. The cycle is repeated as
long as the FDT is in th e weight display mode. Polling is paused while in the function menu or
printing etc. The selected (Fn 01 to Fn 30) FAD may displayed or calibrated via the FAD
calibration procedure in the FDT while all FA Ds are polled. This however limits the response time
of the selected FAD. Refer to ch apter 5 for details of set up and calibration procedures.
