How An Error Message Is Built-Up In The Display; Example Of An Error Display For An Exhausted Battery - ABB AC500 Introduction Manual

How an error message is built-up in the display

An error always consists of an Error Class (E1 to E4, see the previous table) and a number (0 to 63)
which indicates the identifier of the error for direct error recognition. Moreover, there are further four
detailed error codes from d1 to d4 which define the error in detail:
E1...E4 = 00...63 (error identifier)
-> d1 = 000...015
d2 = 000...255
d3 = 000...030
d4 = 000...031

Example of an error display for an exhausted battery

To display the complete error codes, please follow the procedure described below:
The CPU is running. The display only shows
the RUN status and the background lighting is
OFF.
When an error occurs, the red ERR LED goes
on. An error message is output after pressing
the DIAG key and, for example, the screen
shown to the right displays "E4=008". Accor-
ding to the error level, E1 to E4 can be dis-
played.
In this example, "E4=008 " is a warning (E4)
and "008" means "Empty/Missing" .
By pressing on the DIAG button, the LCD
background lighting is turned ON, the error
codes can be displayed to achieve more (dea-
per) diagnostic. The display shows "d1=009"
(detail level 1) and "009" indicates that the
CPU has sent the error.
By pressing DIAG one more time, the display
shows "d2=022" (detail level 2) and "022" indi-
cates that the device type = battery.
By pressing DIAG one more time, the display
shows "d3=031" (detail level 3) and "031"
means "no module type" (= device itself).
By pressing DIAG one more time, the display
shows "d4=031" (detail level 4) and "031"
means "no channel" (= device itself).
By pressing OK, the error is acknowledged
and the display returns to the normal state.
ESC returns to the normal state without ack-
nowledging the error!
