IDENTIFYING AND
CORRECTING ALARM
INDICATIONS
For a Hazardous Area Oxymitter 5000 with a membrane keypad, faults are
indicated by four diagnostic, or unit, alarm LEDs. A pattern of repeating blinks
define the problem. A condensed table of the errors and the corresponding
blink codes can be found on the inside right cover of the electronics housing.
Table 8-1 also identifies the blink code and fault status of each LED.
For a Hazardous Area Oxymitter 5000 with the optional LOI, alarm messages
are displayed on the LOI display window when the alarm status display is
accessed via the LOI menu. A listing of the alarm/fault messages and the
related fault status descriptions and fault numbers are shown in Table 8-2.
