5.16 DAISY-CHAIN CONNECTION

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs
in one of the units. When the fault is removed, the system recovers according to its setting to Safe-Start mode
or Auto-Restart.
Setup DIP-switch SW1-5 should be set to the DOWN position to enable the Daisy-Chain Shut-Off operation.
Other SW1 positions can be set according to the application requirements.
If a fault occurs in one of the daisy-chained units, its PS_OK signal will be set to a low level and the unit front
panel display will indicate the fault. The other units in the daisy-chain will Shut-Off and their front panel display

operation.
displays will indicate "SO". When the fault condition is removed, the units will recover to their last setting
according to their Safe-Start or Auto-Restart setting. Figure 5-6 shows a connection of three units, however the
same connection method applies to systems with a larger number of units.
