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 it for local sensing, simply set positions 1 and 2 of the DIP switch asso-
ciated 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 PS1 and PS2 by
setting positions 1 and 2 of internal DIP switches B3 and C4 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.
