STATUS LED ERROR CODE TABLE
NOTE: The error code signal sequence is always preceeded by a 2 second green light. If more than one error code is present, a 4 second off signal will separate the individual error code signals. Note that the [2 sec.green] is only displayed at the beginning of the entire code sequence, not between codes if more than one error code is present.
Example: (Code. #11 “one long red” followed by “one short red”) followed by (Code. #21 “two long reds” followed by “one short red”).
[2 sec.green] [1.2 sec.red] [1.6 sec.off] [0.4 sec.red] [4.0 sec.off] [1.2 sec.red] [0.4 sec.off] [1.2 sec.red] [1.6 sec.off] [0.4 sec.red]
