D.Operates the flashing warning light on the front panel of the slave UPS indicating that the Main Rotary Switch should not be operated while sync is being acquired with the master UPS.
2.4SYSTEM OPERATION
The Series 300 LBS option performs the following functions:
A.Continuously senses the phase relationship between the outputs of the two UPS modules that make up the system.
B.If the two systems lose sync with each other for more than a predetermined period of time (adjustable from 0.1 to 5 seconds) and the AUTO/OFF switch is set to the AUTO position then the LBS will sync the Designated Slave System (DSS) to the Designated Master System (DMS). The DMS and DSS are selected manually using the master system select switch. If the DSS is on bypass and unable to sync to the DMS then the DMS will sync to the output bus of the DSS. This reselection of the master system will be accomplished automatically.
C.Continuously monitors the sync and the quality of the bypass input voltage to both systems. Once the sync and voltage quality between to two systems have been restored for 5 seconds, the LBS will become dormant and allow each system to operate independently.
Note: Failure of any part of the LBS will not cause system failure. The worst case effect would be that the two systems would not be able to synchronize to each other.
