LG Monitoring View (LGMV) Diagnostic Software and Cable

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 allows 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. Graph: Full screen graph of actual high and low pressures and high and low pressure limits. A slid-

ing bar enables user to go back in time and view data.

3. Control IDU: Enables user to turn on all IDU’s default setpoints of 86°F in heat mode or 64°F in

cool mode.

4. Setting: Converts metric values to imperial values.

5. Making Data: Recording of real time data to a separate file created to be stored on the user’s computer.

6. Loading Data: Recorded data from a saved “.CSV” file can be loaded to create an LGMV session.

7. Electrical Data: The lower half of main screen is changed to show the following:

Figure 28: Sample Cycleview.

• Compressors showing actual speeds

• EEVs

• Indoor Units

• Liquid injection valves

• 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

• Constant compressor

- Current transducer value

- Phase

LGMV is available in different formats, including Mobile LGMV, which is a app for use on wireless devices. Contact your LG

Sales Representative for information about the different formats, and recommended system requirements for any version of

LGMV.

In lieu of connecting to the outdoor unit, user has the option to connect to the indoor unit with the use of a USB to RS-485 connector kit.

When connected through the indoor unit, 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.
