Emerson SERIES 600T Manuel D’Utilisation

The following verifications must be done before performing a regular startup of the Liebert FS (see 

6.5.7 - Starting up the System):
1. Make sure the Liebert FS is properly secured to the floor with the Liebert-provided mounting kit 

and in compliance with the floor mounting instructions in 4.1 - Cabinet Floor Mounting.

2. Check for coolant leaks in and around the Liebert FS unit.
3. Ensure that Liebert FS cabinet panels are in place on the cabinet and that no tools have been left 

in the cabinet

4. Ensure that the Liebert FS Main circuit-breaker (optional) or the customer-provided external DC 

disconnect switch is open

5. Verify that the AC Auxiliary Backup Power is connected and powered by closing fused disconnect 

or wall disconnect and check if the Control Panel is ON and with no warning or fault messages 

displayed.

The Liebert FS may now be started up.

Once AC voltage is applied to the Liebert FS, the Liebert FS Control Panel will boot up. Its screen will 

begin to illuminate after 5 to 10 seconds and then display a series of boot up protocols.

1. It takes about 25 seconds to load and initialize the primary application software at STARTUP or 

after reset.

2. Title block and firmware versions will be displayed (see Figure 82). If the secondary DSP does 

not boot up properly, versions for the secondary DSP may be corrupted or zero.

3. EEPROM checksum will be calculated and compared with the stored value. EEPROM checksum 

fault will be generated if they do not match. For this case, default values are loaded for 

parameters in RAM. However, EEPROM contents are not changed.

4. Response from secondary DSP will be checked. “INTERPROCESSOR COMM FAULT” will be 

generated if the communication is not set up properly. The controller will reset itself for this case.

5. Previous operation command (STARTUP or SHUTDOWN) will be retrieved to determine the 

current operation mode. 

6. Option status is checked. Current available options are VIB and DCM.

The Initial System Startup shall be performed ONLY under the supervision of a Liebert 

technician to ensure proper system operation. Failure to abide by instructions provided herein 

may void your warranty.

NOTE
A regular startup is any startup after the Initial System Startup.

The following procedure assumes that the Initial System Startup has been performed under 

the supervision of a Liebert technician.

Do not attempt to run the system unless the system loads valid parameters.
