PRELIMINARY WARNINGS

The word WARNING preceded by the symbol indicates conditions or actions that put the user’s safety at risk. The word ATTENTION preceded by the symbol indicates conditions or actions that could damage the instrument or connected equipment.
The warranty shall become null and void in the event of improper use or tampering with the module or devices supplied by the manufacturer as necessary for its correct operation, and if the instructions contained in this manu-al are not followed.

• WARNING: The full content of this manual must be read before any operation. The module must only be used by qualified electricians. Specific documentation is available using the QR-CODE shown on page 1.
• The module must be repaired and damaged parts replaced by the Manufacturer. The product is sensitive to electrostatic discharges. Take appropriate measures during any operation.
• Electrical and electronic waste disposal (applicable in the European Union and other countries with recycling). The symbol on the product or its packaging shows the product must be surrendered to a collection centre authorized to recycle electrical and electronic waste.

MODULE LAYOUT

Dimensions LxHxD : 17.5 x 102.5 x 111 mm;
Weight:  110 g; Enclosure: PA6, black

SIGNALS VIA LED ON FRONT PANEL

ANALOGUE INPUT

CHARACTERISTICS

| Input impedance: > 1MΩ; Full scale: ± 30mV ÷ ± 460mVError: 0.01% of the electrical full scale in “factory calibration” mode * Thermal stability: 0.0010%/C° of full scale.

Cell supply voltage: 5 Vdc (supplied by the device) Resolution: ADC 24bit Response time with activated filter: 2 ÷ 850ms configurable

---|---
LOAD CELL CHARACTERISTICS| 4 or 6 wires;Cell minimum impedance: 87 Ω equivalent (possibly deriving from several load cells in parallel) Cell sensitivity: From ±1 mV/V to ±64 mV/V;
ANALOGUE OUTPUT| Voltage output: Configurable between 0 ÷ 10Vdc, minimum load resistance 2kΩ Current output: Configurable between 0 ÷ 20mA, maximum load resistance: 500 Ω Retransmission error: 0.1 % of maximum field; Response time (10%…90%): 5 ms
DIGITAL IN/OUT| Opto-insulated digital input:       Min. voltage: 12 V / Max. voltage: 30 V Opto-insulated digital output:  Max. current: 50 mA / Max. voltage: 30 V

• In the case of “calibration with sample weight” mode, the accuracy is given by the linearity error (0.003% of the electric full scale)

SETTING THE SW1 DIP-SWITCHES

The position of the DIP-switches defines the Modbus communication parameters of the module: Address and Baud Rate The following table shows the values of the Baud Rate and the address according to the setting of the DIP-switches:

SW2 DIP-SWITCH SETTINGS

WARNING
The DIP-switch settings are read only at boot time. At each change, perform a restart.
For use and settings via DIP-SWITCH, see the user manual available on the website on the web page dedicated to the product.

PS BUTTON1
The tare is reset using the PS1 button. To reset the tare it is necessary to hold down the PS1 button for three seconds. The update of the value will be viewable via the Webserver page and/or Modbus.

IDC10 CONNECTOR

The illustration shows the meanings of the various IDC10 connector pins if signals are to be sent via them directly.

WEB SERVER (ONLY ZE-SG3)

To access the maintenance Web Server, use the following credentials: Default user: admin; Default password: admin

CAUTION
DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

FACTORY IP ADDRESS (ONLY ZE-SG3)
The default module IP address is static: 192. 168. 90. 101

USB PORT (ONLY Z-SG3)

The module is designed to exchange data according to the modes defined by the MODBUS protocol. It has a micro USB connector and can be configured using applications and/or software programs. The USB serial port uses the following communication parameters: 38400 BAUD, 8BIT, NO PARITY, 1 STOP BIT, ModBUS ADDRESS 1.
The USB communication port responds exactly like the RS485 port with the exception of the communication parameters. While using the USB port, the RS485 port is disabled.

ELECTRICAL CONNECTIONS

CAUTION
The upper power supply limits must not be exceeded, as this could cause serious damage to the module. To meet the electromagnetic immunity requirements:

• use shielded signal cables;
• connect the shield to a preferential instrumentation earth system;
• separate shielded cables from other cables used for power installations (inverters, motors, induction ovens, etc…).
  

Load cell

Connection to the load cell via 4 or 6 wires: The terminals have the following meaning:

• 13: Load cell positive supply
• 11: Load cell positive supply reading
• 9: Cell reading positive
• 12: Load cell negative supply reading
• • 14: Load cell negative supply
• 10: Cell reading negative
• For the connections, the use of screened cables is required.
