Typically input contacts interfacing with a signaling system are used. In single-bit applications, HYB POTT RX1 must be used. In two-bit applications, HYB POTT RX1 and HYB POTT RX2 must be used. Infour-bit applications, HYB POTT RX1, HYB POTT RX2, HYB POTT RX3, and HYB POTT RX4 must be used.Figure 5–160: HYBRID POTT SCHEME LOGIC837015AL.CDRSETTINGSETTINGSETTINGSSETTINGSSETTINGSETTINGSETTING SETTINGSETTINGSETTINGSETTINGSSETTINGFLEXLOGIC OPERANDSFLEXLOGIC OPERANDSFLEXLOGIC OPERANDFLEXLOGIC OPERANDHYB POTT SCHEMEFUNCTION:HYB POTT RX PICKUPDELAY:HYB POTT SEAL-INDELAY:ECHO DURATION:TRANS BLOCK PICKUPDELAY:TRANS BLOCK RESETDELAY:PH DIST Z2 PKPPH DIST Z4 PKPPH DIST Z1 PKPLINE PICKUP LEO PKPOPEN POLE OPLINE PICKUP UV PKPHYB POTT OPDisabled=0Off=0OffGND DIR O/C FWD: HYB POTT WEAKINFEED:HYB POTTPERMISSIVE ECHO:HYB POTT W/I COND:GND DIR O/C REV:HYB POTT RX1:HYB POTT RX2:HYB POTT RX3:HYB POTT RX4:HYB POTT NO OFCOMM BITS:HYB POTT ECHO COND:GND DIST Z2 PKPGND DIST Z4 PKPGND DIST Z1 PKPORORORORORORANDANDANDANDANDEnabled=1Off = 0OffOff = 0Off = 0Off = 0Off = 0Off = 0Off = 0t PKP0t PKP0t RSTt RSTANDANDEcho duration andlockout logicECHO LOCKOUT:FLEXLOGIC OPERANDSHYB POTT NO OFCOMM BITS:HYB POTT TX1HYB POTT TX2HYB POTT TX3HYB POTT TX4ECHO TABLETRANSMIT TABLEPhaseSelectorRXRUNRUNFLEXLOGIC OPERANDSHYB POTT NO OFCOMM BITS:HYB POTT TRIP AHYB POTT TRIP BHYB POTT TRIP CHYB POTT TRIP 3PTRIP TABLERUNEnabledEnabledCustomCustomDisabledDisabled0100 msecANDSETTINGHYB POTT BLOCK:Off = 0PhaseSelectorFLEXLOGIC OPERANDSAR FORCE 3P TRIPOPEN POLE OPFLEXLOGIC OPERANDSAR FORCE 3P TRIPOPEN POLE OPSETTINGSETTINGPhaseSelectorRXFLEXLOGIC OPERANDSAR FORCE 3P TRIPOPEN POLE OP
