Types of Individual Alarms

K6CM's individual alarm type and threshold setting range are as follows.
For individual alarms, it is possible to set the level of Warning and Critical, respectively.
For the K6CM-VBM, the threshold values can be set automatically with the software tool by using the
threshold automatic setting function. For details, refer to 6-1-4 Buttons on Device Setting on page 6-13.

*1. In the case of the upper limit alarm, it is necessary that the threshold of Critical > Warning is satisfied. If Critical
threshold ≤ Warning threshold, the Warning threshold is ignored and only the Critical threshold exists.
In the case of the lower limit alarm, it is necessary that the threshold of Critical <Warning is set. If Critical thresh-
old ≥ Warning threshold, the Warning threshold is ignored and only the Critical threshold exists.

What is Comprehensive Alarm?

Comprehensive alarms are judged as integrated OR logic with the priority order as "Critical" > "Warn-
ing" > "Normal" for each individual alarm.
It is as follows.
Types of comprehensive alarm
Normal
Warning
Critical
Example: When the measurement value is two:
Individual alarm
Normal and Normal
Warning and Normal
Warning and Warning
Critical and Normal
Critical and Warning
Critical and Critical
Note To specify the type of individual alarm that exceeds the alarm threshold, operate the DISP key in the front of
the K6CM device to check the measurement value by monitoring type.

When there is neither "Critical" nor "Warning" in the individual alarm.
When there is not even one "Critical" level in the individual alarm, and at least one "Warn-
ing" level.
When there is at least one "Critical" level in the individual alarm.
