			Amps at analog input 1, slave2, have dropped below 4mA		(slave1) -X428:4, 5.
	F077		Aninput2 SL2		Check connection from signal source to SCI1
			Amps at analog input 2, slave2, have dropped below 4mA		(slave 2) -X428:7,8.
	F078		Aninput3 SL2		Check connection from signal source to SCI1
			Amps at analog input 3, slave2, have dropped below 4mA		(slave 3) -X428:10, 11.
	F079		SCB telegram		•	Check the connections of the SCB1(2).
			A telegram has not been received from the SCB (USS,		•	Check P687.01"SCom/SCB TlgOFF".
			peer-to-peer, SCI) within the telegram failure time.		•	Replace the SCB1(2).
					•	Replace the CU (-A10).
	F080		TB/CB init.		r949 = 1 TB/CB not inserted or TB/CB board code
			Board initialization error at the DPR interface		incorrect
					r949 = 2 TB is not compatible
					r949 = 3 CB is not compatible
					r949 = 5 Error in initialization data
					Check contacts on the T300 / CB board and whether the
					board slot matches the appropriate parameter setting;
					•	P090 Board Position 2,	• P091 Board Position 3
					•	r723 PCB Code,	• r724 PCB Code
					r949 = 6 Timeout during initialization
					r949 = 10 Error in configuration channel
					Check the CB initialization parameters;
					•	P918 CB Bus Address,
					•	696 to P705 CB Parameters 1 to 10
	F081		TB/CB heartb.		•	Replace the TB or CB
			TB or CB is no longer processing the monitoring counter		•	Check the connection between the subrack and option
						board
	F082		TB/CB Tlgr.		•	Check the connections of the CB/TB.
			No new process data have been received from the TB or		•	Check P695 "CB/TB TlgOFFTime".
			CB within the telegram failure time.		•	Replace the CB.
					•	Replace the TB.
	F091	Form.interrupt			•	Depending on the fault
			Forming of the DC link has been interrupted.		•	Line voltage too low or incorrect line voltage (P071)
			r949 = 1 Abortion due to another fault			parameterized
			r949 = 2 Abortion because Vd too low		•	OFF command
			r949 = 3 Abortion by OFF command
					•	No ON command
			r949 = 4 Abortion because no ON command within 20 s
			of forming function selection
	F255		Fault in NOVRAM		Switch the device off and then on again.
					Replace the CU if the fault occurs again.
