3.4 Setting Alarm Type
·
Three alarm outputs are supported: alarms 1 to 3. Of these, only the
alarm assigned as the output can be used.
·
Alarm output conditions are determined according to the combination
of the “alarm type”, “alarm value” and “alarm hysteresis” parameter
settings.
·
The contact conditions when alarm output is ON can be set to “open”
or “closed” in the “close in alarm/open in alarm” parameter.
·
The following table shows the alarm types supported by the E5AK con-
troller and their respective operations.
