8.8 Flashing error codes
When a fail c
ondion becomes acve, the red alarm lights connuously or shows a
ashing sequence.
If the error light is on connuously, this shows a problem with the embedded soware.
Restart the system. If restarng the system does not clear the fault, a soware download
is necessary. Contact us or the supplier. If the alarm LED is ashing, idenfy the error
ash code and refer to Table: Flashing error codes.
Sucient o period is there between each subsequent cycle repeon to mark the start
of a new ash sequence. The duraon of a long ash (L) is equal to 3 mes the duraon
of a short ash (0.5 s).
