5.11.6 Alarm indicator codes
Whenever a fail condition becomes active the red alarm indicator shows a flashing sequence. If the error light is on
continuously this indicates a problem has been found with the embedded software. In this case, try cycling the
power. If cycling the power does not clear the indication, a software download may be required. In this situation,
contact the supplier or Edwards. If the alarm indicator is flashing, identify the error flash code and consult Table 15.
There is a sufficient off period between each subsequent cycle repetition to clearly mark the start of a new flash
sequence. The duration of a long flash (L) is equal to 3 times the duration of a short flash (0.5 s).
