5.6 Daisy-Chain Connection
It is possible to configure a multiple power supply system to shut down all units when a fault
condition occurs in one of the units. When the fault is removed, the system recovers according to
a preset state: Safe start mode or Automatic restart.
Set signal ”
SO
” to positive logic via Front panel (refer to section 5.7.1) . If a fault occurs in one of
the units it’s ”PS_OK” signal will be set to low level and the display will indicate the fault. The other
units will shut off and their displays will indicate ”
SO
”. When the fault condition is removed, the
units will recover to their last setting according to their respective Safe start or Auto-restart setting.
Fig.5-6 shows connection of three units, however the same connection method applies to systems
with more units.
