2.4.1.1 INDEPENDENT OPERATION - LOCAL SENSING USING REAR PANEL DIP SWITCHES
The rack adapter slots are preconfigured at the factory for local sensing using rear panel 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 1-3 for DIP switch locations. Figure 2-2 illustrates local sensing of PS1 and PS2 by
setting positions 1 and 2 of rear panel DIP 1 and 2 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.
