Alarm code display
The DCP551 is designed to alternate display of the following alarm codes and normal
display items in one-second intervals on display panel 1 when input failures or instru-
ment system failures are detected.
In cases of multiple alarm codes, display of the codes is alternated with normal display
items, starting in order from the alarm code with the smallest number.

Alarm classification
PV range alarm group
:
AL01
to
AL04
Measuring instrument alarm group :
AL90
to
AL99
, and battery voltage drop
(In case of battery voltage drop,
BAT
LED of the
console is flickered.)
*1:
When
AL90
is generated, the alarm code stays on and continued operation is dis-
abled.
*2:
Data checks performed by
AL93
and
AL97
may fail to detect corrupted data.
When this happens, the alarm can be turned off by entering normal data.

Display behavior and alarm code upon input burnout
Display behavior (upscale/downscale) and alarm code upon input burnout differ
depending on the input type.
