5.5.1 Flashing Service Codes
Whenever a service is required the standard once per revolution flash on the yellow status LED is replaced with a
service flash code. The Service flash codes are specified in Table 23.
Table 26 - Flashing service codes
5.5.2 Flashing error codes
Whenever a Fail condition becomes active the red Alarm LED will slow the Error Flash Codes that reflect all active
error conditions. The Fail status flash code positions, within the Alarm LED error flash sequence, are specified in
Table 27 .
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 (0.5s).
