2.4.1.1 INDEPENDENT OPERATION - LOCAL SENSING USING INTERNAL DIP SWITCHES
The rack adapter slots are preconfigured at the factory for local sensing using internal DIP
switches. If a slot has been configured for other than local sensing using DIP switches and it is
necessary to reconfigure a slot for local sensing, simply set positions 1 and 2 of the DIP switch
associated with that slot to ON (closed). External sensing connections must be removed. When
set to ON (closed), DIP switch position 1 connects (V+) to (S+) and position 2 connects (V–) to
(S–). See Figure 2-1 for DIP switch locations. Figure 2-2 illustrates local sensing of PS6 and
PS7 by setting positions 1 and 2 of internal DIP switches E7 and F8 to ON (closed); positions 3
and 4 must be set to OFF (open). Position 5 (current share) must be set to OFF and positions 6,
7, and 8 (alarms) can be configured per PAR. 2.4.4.
