Warning List - Omron R88M-K Series User Manual

11-2 Warning List

This is a function to output a warning signal before the protective function operates to notify the overload and other statuses in advance.
Set the warning output type to Warning Output Selection 1 (Pn440) and Waning Output Selection 2 (Pn441).
Precautions for Correct Use
 Each warning automatically returns to the status before it occurred once the system recovers from the error.
However, for the time set in the Warning Latch Hold Time Selection (Pn627), the warning status will be held.
To clear the warning during the latch hold time, do so by performing the same procedures as alarm clear.

*1. The "√" fields can be set to 1 to 10 s in the Warning Latch Hold Time Selection (Pn627) or to the no-
time limit setting. However, the battery warning is fixed with no time limit.
*2. Select the type of warning to be output in warning output 1 (WARN1) and warning output 2 (WARN2)
in the Warning Output Selection 1 (Pn440) and Warning Output Selection 2 (Pn441).If you set this to
0, all warning types will be output.Do not set it to a value other than above.
*3. Each warning detection can be masked using the Warning Mask Setting (Pn638). The corresponding
bits are shown in the table.
The warning detection is masked when the bit = 1.
