J2-39 EX SYNC HI: External Sync High signal. This is an input that can be used
to synchronize the outputs of the AC Power System. This input requires a
logic high level of at least +4.5 VDC at 5 MA. The input should have a duty
cycle 50 ±30%. J2-15 is the common input. The External Sync input is
optically isolated. It must also be enabled from the SNC screen.
J2-40 Solid State C: Control the solid state option switch for Phase
C.
J2-41 Solid State A: Control the solid state option switch for Phase
A.
J2-43 REMOTE SHUTDOWN: This is a logic input that can be used to remove
the programmed output voltage. A logic low on this pin will cause the output
voltages to be programmed to 0.0 volts and the output relays to open. A logic
high will cause the programmed output voltage to be restored at the output
terminals. A contact closure between this pin and j2-34 (D COM) will
simulate a logic low state.
J2-44 DFI1, Discrete Module failure
DFI1 and DFI2 will have a contact closure between them when there is a
failure in one of the modules or when there is no power.
J2-48 SEN COM A: Make no connection
J2-49 SEN COM B: Make no connection
J2-50 SEN COM C: Make no connection
