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 with-

out 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:

Additional screens can be accessed by tabs on the main screen:

1. Cycleview: Graphic of internal components including:

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:

• Compressors showing actual speeds

• EEVs

• IDUs

• Low and high pressures

• Temperature and pressure sensors

• Four-way reversing valve

• Outdoor fans showing status and speeds

• Inverter compressor

- Amps

- Volts

Power Hz

- Inverter control board fan Hz

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.
