7.0TROUBLESHOOTING / FAQS

1.How do I obtain the software necessary to monitor and configure the Liebert LDM?

•The software package is available from Liebert’s Web site: http://www.liebert.com/product_pages/ProductDocumentation.aspx?id=72

2.What is contained in the downloaded software package?

•The downloaded file from Liebert’s Web site is a zip file that contains:

•the flash program with a walk-through instruction

•the configuration program

•the monitor program

•the latest firmware file (to update the Liebert LDM firmware using the flash program)

3.What should I do if the BMS is reporting an overcurrent alarm?

•Verify the circuit is not actually overloaded.

•Using the Configuration program, verify alarm setpoints and CT ratio is correct.

•If settings are correct, verify that the BMS is operating correctly.

•If the issue still exists, contact Liebert Services at 1-800-LIEBERT (1-800-543-2378) for assis- tance.

4.I get an error message “Incorrect Schema Version” when I try to run the Monitor tool or Configuration tool. What should I do?

•Ensure that only one program—either Monitor or Configuration—is running at a time. You can’t run both programs at the same time.

•Ensure the latest firmware is loaded into the BCB. Please visit Liebert’s Web site for firm- ware updates. If a firmware upgrade is necessary, refer to 5.6 - Upgrading the Firmware.

•Verify the PC is connected to the LDM Setup port and the cable is fully seated (see 5.2.1 - LDM Setup Port Connection).

•Verify the Liebert LDM unit has power (green LEDs on the BCB will be flashing).

5.How can I make a backup copy of the configuration file?

•Connect to the external LDM Setup port (see 5.2.1 - LDM Setup Port Connection).

•Run the configuration program (see 5.5.1 - Starting the Configuration Program).

•At the bottom of the Configuration window, select Save to File. Navigate to a location on your PC to store the file (see 5.5.5 - Save the Configuration File to Disk).
