WARNINGS READ this manual BEFORE operating or servicing on the instrument. FOLLOW these instructions carefully. SAVE this manual for future use. CAUTION The installation and maintenance of this instrument must be allowed to qualified personnel only. Be careful when you perform inspections, testing and adjustment with the instrument swithced on. -
Page 5: Introduction
INTRODUCTION The DAT 100 is a weight transmitter to be matched to the load cells to detect the weight in every situation. The module is easy to install and can be mounted on 35 mm DIN rail. The display allows easy reading of the weight, the configuration parameters and errors. -

Page 7: Installation
The DAT 100 consists of a motherboard, to which are added the options available, accommodated in a plastic enclosure for DIN rail 35mm. The DAT 100 should not be immersed in water, subjected to jets of water and cleaned or washed with solvents. - Page 8 2 with 5 and 3 with 4 . Connect the cell cable shield to the terminal 1. In the case of the usage of two or more load cells, use special jun- ction boxes (CEM4/C or CSG4/C). J-BOX CGS4/C DAT 100 +EXC +EXC -SGN SIGN-...
- Page 9 LOGIC INPUTs The two logic inputs are opto-isolated. The connection cable should not be channeled with power cables . The function of the two inputs is as follows: INPUT 1* TARE/ZERO INPUT 2 PRINT The activation of the two functions is accomplished by bringing the external 24 VDC power supply to the corresponding terminals as shown in the figure here beside.
- Page 10 DAT 100/A TRANSMITTER ANALOG OUTPUT The instrument provides an analog output in current and voltage. Analog voltage output: range from -10 to +10 V or -5 to +5 volts, 10K ohm minimum load. Analog current output: range from 0 to 20 mA or 4 to 20 mA. The maximum load is 300Ω.

FRONT PANEL The DAT 100 transmitter has a front door that protects the 5 digits display, the 2 status LEDs and the three front keys. In operating mode the display shows the weight and the LEDs indicate the status of weight (net-gross). - Page 12 hardware DAT 100/RS485 module rS485 hardware DAT 100/A module ANALG It’s important to communicate these data in the event of a request for assistance. ERRORS NOTIFICATION In the operating mode, the display can report the following error codes.

Page 13: Viewing, Zeroing The Weight And Autotare
VIEWING, ZEROING THE WEIGHT AND AUTO TARE When the instrument is switched ON, the display shows the current net weight. VIEWING THE NET WEIGHT/GROSS WEIGHT Press the key to toggle between the net weight to gross weight and vice versa. The value displayed is reported by the LED 1 (lit: net weight). - Page 14 The calculated peak is not retained at power off. ▼ ▼ WEIGHT SETPOINT SET UP (ONLY DAT 100/A) The set point values are compared to the weight to drive its logic output. The comparison criteria is established in the set up procedure of the logic I / O (see relevant paragraph).

Page 15: Set-Up
SET UP GENERAL INFO All functions of the DAT 100 can be and amended through a simple setup menu, shown on the next page. All the settings activated or selected are stored even after switching off the transmitter. The DAT 100 is factory set. See the “default” parameters on the following pages. -

You must complete these steps with the zero calibration described on the next page. The procedure ensures, in the absence of mechanical problems, a good accuracy of the system (maximum error <1% FS).
- Page 18 CALIB - CALIBRATION The calibration method below, is used to correct or reduce the linearity error of the weighing system. The calibration should be performed with the use of sample weight or pre-weighed product on a sample weighing system. Before proceeding with the calibration of the full scale, always perform the zero calibration. During the calibration phase, the display shows the weight intermittently with the inscription CAL.

- Page 35 NOTES ON THE OPERATION OF THE ANALOG OUTPUT LIMITS When the weight exceeds the analog full-scale, the output takes a positive saturation value of about 10.7 V for the voltage output and 21.2 mA for current output. When the weight is negative or in an error condition, the output takes a negative saturation value of about -10.5 V for the voltage output and -0.2 mA for current output.
