EDI LMD Series Operation Manual

2.6.1 CURRENT FAULT

If a fault is detected, both the DET (Red) and FLT (Yellow) LEDs continuously emit a
sequence of flashes and the DEFLECTOMETER will display the letter "F". Each type of
fault is identified by a different flash sequence followed by a one second pause:
Flash Sequence
1 flash
2 flashes
3 flashes

2.6.2 PREVIOUS FAULT

If the fault condition is removed, the DET indicator and the channel output will return to
normal operation. The FLT indicator will continue to flash indicating that a fault had
previously occurred. This Previous Fault indication may be reset by momentarily pressing
the MODE and FREQ buttons simultaneously. See section 2.5.2.
