Faults and Alarms						01.2004
			Fault messages
	No.		Description of fault		Remedial measures
	F046		Par.con.	Switch the device off and on again.
				Replace the CUSA (-A10) board.
	F047		Int.comp.time	Replace the CUSA (-A10) board.
	F048		Interf. pulse freq	Switch the device off and the on again.
			Fault during power OFF or pulse inhibit	Replace the CUSA (-A10) board if the fault occurs again.
	F049		SW release	•	Replace the language EPROM
			The SW versions of the EPROMs on the CU are different.
			The fault occurs as a result of the comparison of the
			language EPROM and CU software.
	F050		TSY init.	Check whether
			TSY board initialization error	• the TSY is correctly inserted
				•	the parameter is set correctly for the installed board
				• P090 Board Position 2		• P091 Board position 3
				• r723 PCB Code		• 724 PCB Code
	F060	MLFB missing		Enter the appropriate MLFB in parameter P070 MLFB
			This fault is set if the MLFB = 0 (0.0 kW) when the device	(6SE70..) after acknowledgement in INITIALIZATION.
			exits the INITIALIZATION state. MLFB = order number.	(MLFB can be entered only if the appropriate access
				levels are set in the two access parameters.)
	F062		Multiparal.	•	Check ImPI and the communications card and if
			Fault in connection with the multiparallel circuit has been		required, replace
			detected	• Check configuration and connections of the
					multiparallel circuit
				•	Check parameter settings (P070 "MLFB(6SE70..)")
				•	Replace the CUSA (-A10).
				•	Replace the ImPI
	F065		INT1 telegram	•	Check the connection CU -X100:1 to 5 or check
			No telegram has been received on interface 1		connection PMU -X300.
			(SCom1/USS protocol) within the telegram failure period.	•	Check P687.01"SCom/SCB TlgOFF"
				•	Replace the CUSA (-A10).
	F070		SCB init.	r949 = 1 or 2
			SCB board initialization error	•	Check the contacts on the SCB and whether the board
					slot matches the appropriate parameter setting.
				•	r723 PCB Code ,	• r724 PCB Code and
				•	P090 Board Position 2,	• P091 Board Position 3
				r949 = 5 Error in initialization data
				•	Check parameters P682 and P684
				r949 = 6 Timeout during initialization and
				r949 = 10 Error in configuration channel
				• Check parameters P090, P091, P682 and P684
	F072		SCB heartb.	•	Replace the SCB
			SCB is no longer processing the monitoring counter	•	Check the connection between the subrack and option
			(heartbeat counter).		board
	F073		Aninput1 SL1	Check connection from signal source to SCI1
			Amps at analog input 1, slave1, have dropped below 4mA	(slave 1) -X428:4, 5.
	F074		Aninput2 SL1	Check connection from signal source to SCI1
			Amps at analog input 2, slave1, have dropped below 4mA	(slave 2) -X428:7, 8.
	F075		Aninput3 SL1	Check connection from signal source to SCI1
			Amps at analog input 3, slave1, have dropped below 4mA	(slave 3) -X428:10, 11.
