CHAPTER 1: GETTING STARTED
The LRD micro PLC is an electronic device. For safety reasons, 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 LRD controller.
WARNING: Personal injury may result from improper operation.
CAUTION: The LRD may be damaged by improper operation.
PRECAUTION FOR INSTALLATION
Compliance with the installation instructions and the user manual is absolutely necessary. Failure to comply could lead to improper
operation, equipment damage or in extreme cases even death, serious body 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 LRD is open and exposed. For the open-board models, all electrical components are exposed. For this reason, it is
recommended the LRD be installed in an enclosure or cabinet to prevent accidental contact or exposure to the electrical circuits and
components.
Never install the product in an environment beyond the limits specified in this user manual such as high temperature, humidity, dust,
corrosive gas, vibration, etc.
PRECAUTION FOR WIRING
Improper wiring and installation could lead to death, serious body injury or considerable damage to property.
The LRD should only be installed and wired by properly experienced and certified personnel.
Make sure the wiring of the LRD meets all applicable regulations and codes including local and national standards and codes.
Be sure to properly size cables for the required current rating.
Always separate AC wiring, DC wiring with high-frequency switching cycles, and low-voltage signal wiring.
PRECAUTION FOR OPERATION
To insure safety with the application of the LRD, complete functional and safety testing must be conducted. Only run the LRD after all
testing and confirmed safe and proper operation is complete. Any potential faults in the application should be included in
the testing. Failure to do so could lead to improper operation, equipment damage or in extreme cases even death, serious body injury
or considerable damage to property.
When the power is on, never contact the terminals, exposed conductors or electrical components. Failure to comply could lead to
improper operation, equipment damage or in extreme cases even death, serious body injury or considerable damage to property.
It is strongly recommended to add safety protection such as an emergency stop and external interlock circuit in case the LRD relay
operation must be shut down immediately.
EXAMINATION BEFORE INSTALLATION
Every LRD has been fully tested and examined before shipment. Carry out the following examination procedures after unpacking your LRD micro
PLC.
– Check to see if the model number of the LRD matches the model number that you ordered.
– Check to see whether any damage occurred to the LRD during shipment. Do not connect the LRD to the power supply if there is any sign of
damage.
Contact Customer Service (Tel. +39 035 4282422 - email: [email protected]) if you find any abnormal conditions as mentioned above.
ENVIRONMENTAL PRECAUTIONS
The installation site of the LRD is very important. It relates directly to the functionality and the life span of your LRD. Carefully choose an
installation site that meets the following requirements:
– Mount the unit vertically
– Environment temperature: -20°C...55°C (-4°F...131°F)
– Avoid placing LRD close to any heating equipment
– Avoid dripping water, condensation, or humid environment
– Avoid direct sunlight
– Avoid oil, grease, and gas
– Avoid contact with corrosive gases and liquids
– Prevent foreign dust, flecks, or metal shavings from contacting the LRD
– Avoid electric-magnetic interference (soldering or power machinery)
– Avoid excessive vibration; if vibration cannot be avoided, anti-vibration mounts should be installed to maintain system equilibrium.
