8.8 Flashing error codes
When a fail condition becomes active, the red alarm lights continuously or shows a
flashing sequence.
If the error light is on continuously, this shows a problem with the embedded software.
Restart the system. If restarting the system does not clear the fault, a software download
is necessary. Contact us or the supplier. If the alarm LED is flashing, identify the error
flash code and refer to Table: Flashing error codes on page 82 .
Sufficient off period is there between each subsequent cycle repetition to 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).
