2.4.4.1.2 CLOSE ON FAILURE USING EXTERNAL WIRING AT I/O MATING CONNECTOR
Close on failure for multiple power supplies can be accomplished by wiring N.O. and COM in
parallel at the I/O mating connector. DIP switches associated with slots included in the alarm cir-
cuit must have positions 6 and 7 set to OFF (open). The failure indication (short circuit) will be
present across any pair of N.O. and COM lines. Figure 2-13 is a simplified diagram illustrating a
close on failure alarm configuration for four power supplies using external wiring at the I/O mat-
ing connector.
