Elevator Diagnostic Codes
Code	Title	Description
ELF1	Elevator Position Vend (EPVD) failed	Failed to get to the Vend position following a position Vend command
ELF2	Lock switch 1 and 2 both high (Invalid Condition)	Logically both slide switches can never be operated at the same time
ELF3	Baffle close (EBCL) failed to complete	Failed to close the security baffle following a 'close baffle' command
ELF4	Baffle open (EBOP) failed to complete	Failed to open the security baffle following an 'open baffle' command
ELF5	Elevator Position Standby (EPSB) failed	Failed to get to the Standby position following a 'Position Standby' command
ELF6	Elevator Shelf Position (ESELx) failed	Failed to get to the required shelf position following a position shelf command
ELF7	Motor fails to move	No motor movement for a period of 1 second, as determined by the dual encoder signals
ELF8xy	Shelf number mismatch	A mismatch of shelf numbers between the VMC controller & Elevator controller after a reset sequence (ERST) e.g. EFL8-04_05 = 4 shelves were identified by the Elevator controller when it was told there are 5.  Both numbers will always be 2 digit. EFL8-00_05, would mean no shelves were identified which would indicate there is a sensor or wiring failure.
EFL9	Delivery Door opened unexpectedly	Should the delivery door be opened outside of a vend cycle the elevator will be immediately be sent to the 'Vend' position and an ELF9 will be reported. The VMC controller will then issue a go to Standby command once the delivery door has been closed.
ELF98	Command out of Sequence	Will be returned as part of the elevator status reply if any other command is issued other than a 'Reset' or 'Position Standby' command at power-up.
EFL99	At top limit switch.	Will be returned as part of the elevator status reply if a command is issued if the elevator is stationary at the top limit for any reason
