NOTES:

1.Slow flash is 1 flash every 2 seconds.

2.Fast flash is 2 flashes every 1 second.

3.EXAMPLE: “Flashing Code 2” is represented by 2 fast flashes followed by a 10-second pause. This sequence will repeat continually until the fault is cleared.

NOTES:

1.If there is no fault in memory, the Fault LED will flash code 1.

2.Codes will be displayed with a 10-second Fault LED pause.

3.Slow flash is 1 flash every 2 seconds.

4.Fast flash is 2 flashes every 1 second.

5.EXAMPLE: “Flashing Code 2” is represented by 2 fast flashes fol- lowed by a 10-second pause. This sequence will repeat continually until the fault is cleared.
