2. Outlines
• IntroducGon
• Machine Current Monitoring system
• SoluGons
• Benefits
• Why Choose ICP DAS?

3. IntroducGon
• Remote monitoring, diagnosis and maintenance are
three key funcGons that equipments must have in
the future
• Help customers to improvement equipment
reliability, maintenance and uGlizaGon

4. The Problem
Original funcGon at machine:
• ProducGon order history
• 3-color tower light system
Database
Insufficient machine informa=on:
• No real =me & detailed opera=onal
informa=on
• Unable to overhaul machine quickly
• Need to shut down machine for
troubleshoo=ng

5. The requirement
l Factory Monitoring
ü Machine operaGon and maintenance
ü Electricity consumpGon
ü Environmental monitoring
l Measure the mixture of AC/DC signal and single/three
phases inverter and motor in a single module.
l Do not change the current wiring structure
l Central real Gme remote monitoring system
l Query historical data from database

17. SoluGons
• Equipment prevenGve maintenance (current
monitoring)
– DN-831I-100V-50A (Voltage Adenuator and Current
Transformer)
– M-7017RMS (8 CH True RMS Input Module)
– I-7520 (RS-232 to RS-485 converter)
• Environment monitoring
– DL-302 (CO2/Temperature/Humidity/Dew Point Data
Logger)
• CommunicaGon & Management
– NS-208 (Ethernet switch)
– InduSoZ/EZ Data Logger

18. Benefits
• Abnormal in process à InvesGgate the
possible factor by motor operaGon log file
• Machine malfuncGonà Find out root cause by
analyzing historical data
• PrevenGve maintenanceà early detecGon of
equipment malfuncGon by system alert
• AdjusGng the process parameters to improve
yields and quality

19. Why choose ICP DAS ?
• The output of motor /device are AC and DC
Signal. Current is the major measurement.
– General Power Meter can only measure AC but DC
– Power Meter Manufactures don’t offer DC type
meter.
• Clip on (Hinged) CT is easy to installed. Not
necessary to change the wiring of motor.
• ICP DAS offers our customers one Stop
Shopping. We propose system integraGon of
Somware (InduSom) and Hardware.
