Chapter 1: Getting Started 1
Chapter 1: Getting Started
The SG2 tiny smart Relay is an electronic device. For safety reasons, please carefully read and
follow the paragraphs with "WARNING" or "CAUTION" symbols. They are important safety
precautions to be aware of while transporting, installing, operating, or examining the SG2
Controller.
W ARNING: Personal injury may result from improper operation.
CAUTION: The SG2 smart relay may be damaged by improper operation.
Precaution for Installation
Compliance with the installation instructions and the user manual is absolutely necessar y . Failure to
comply could lead to improper operation, equipment damage or in extreme cases even death, serious bodily
injury
or considerable damage to property .
When installing the open-board models, insure that no wiring or foreign materials can fall into the exposed
circuits
and components. Damage to equipment, fire , or considerable damage to property could result.
Always switch off power before you wire , connect, install , or remove any module.
The wiring for the SG2 smart relay is open and exposed. For the open-board models, all electrical

PC Programming Software “SG2 Client”
The SG2 Client programming software provides two edit modes, Ladder Logic and Function Block
Diagram (FBD).
The SG2 Client software includes the following features:
1. Easy and convenient program creation and editing.
2. Programs can be saved on a computer for ar chiving and reuse. Programs can also be uploaded directly
from an SG2 and saved or edited.
3. Enables users to print programs for reference and review .
4. The Simulation Mode allows users to run and test their program before it is loaded to the controller .
5. Real-time communication allows the user to monitor and for ce I/O on the SG2 smart relay operation during
