Table 3−6 Controller Alarm Indications (Sheet 8 of 8)
NOTE
If the controller is configured for four probes without a DataCORDER, the DataCORDER alarms AL70 and
AL71 will be processed as Controller alarms AL70 and AL71. Refer to Table 3−10, page 3−42.

#
Internal
Microprocessor
Failure
The controller performs self-check routines. If an internal failure occurs, an “ERR”
alarm will appear on the display. This is an indication the controller needs to be re-
placed.
ERROR DESCRIPTION
ERR 0-RAM failure Indicates that the controller working memory has failed.
ERR 1-Program Memory
failure
Indicates a problem with the controller program.
ERR 2-Watchdog
time-out
The controller program has entered a mode whereby
the controller program has stopped executing.
ERR 3-N/A N/A
ERR 4-N/A N/A
ERR 5-A-D failure
The controller’s Analog to Digital (A-D) converter has
failed.
ERR 6-IO Board failure Internal program/update failure.
ERR 7-Controller failure Internal version/firmware incompatible.
ERR 8-DataCORDER
failure
Internal DataCORDER memory failure.
ERR 9-Controller failure Internal controller memory failure.
In the event that a failure occurs and the display cannot be updated, the status
LED will indicate the appropriate ERR code using Morse code as shown below.
E R R 0 to 9
ERR0 = . .-. .-. -----
ERR1 = . .-. .-. . ----
ERR2 = . .-. .-. . . ---
ERR3 = . .-. .-. . . . --
