lg Monitoring View (lgMV) Diagnostic Software and cable
(PRCTSL1 and PRCTFE1)
LGMV software allows the service technician or commissioning agent to connect a computer
USB port to the outdoor unit main printed circuit board (PCB) using an accessory cable
without the need for a separate interface device. The main screen for LGMV shall allow user
to view the following real time data on one screen:
• Actual inverter compressor speed
• Target inverter compressor speed
• Actual outdoor fan speed
• Target outdoor unit fan speed
• Actual superheat
• Inverter compressor current value
• outdoor air temperature
• Actual high pressure/saturation temperature
• Actual low pressure/saturation temperature
• Suction temperature
• Inverter compressor discharge temperature
• outdoor coil pipe temperature
• Liquid line pipe temperature
• Inverter compressor operation indicator
light
• Four-way reversing valve operation
Additional screens can be accessed by tabs on the main screen:
1. Cycleview: Graphic of internal components including:
• Compressors showing actual speeds
• EEVs
• IDUs
• Low and high pressures
2. Setting: Converts metric values to imperial values.
3. Making Data: Recording of real time data to a separate file created to be stored on the
user's computer.
4. Loading Data: Recorded data from a saved ".CSV" file can be loaded to create an LGMV
session.
5. Electrical Data: The lower half of main screen is changed to show the following:
• Inverter compressor
- Amps
- Volts
The software is available in a high version with all of the features listed above. The low version has all features as the high version without
Target High Pressure and Target Low Pressure values shown on main screen.
In lieu of connecting to the oDU, user has the option to connect to IDU with the use of a USB to RS-485 connector kit. When connected
through IDU, user will not be able to record data.
This software can be used to both commission new systems and troubleshoot existing systems. LGMV data can be recorded to a ".CSV" file
and emailed to an LG representative to assist with diagnostic evaluations.
