10.13  Alarms 

There are 32 software alarms available split into 4 alarm groups.   

Alarm condition can be set for any measured quantity, also for quantities measured on 
analogue inputs or signals from digital inputs. 

Alarms can trigger different actions according to their settings: 

  Visual (alarms cause alarm LED to light) 

  Sound (alarms can cause audible indication) 

  Relay switch (alarms can switch digital outputs on main and aux. I/O modules) 

The alarm status can also be stored in the Recorder. 

CAUTION 

New values of alarm settings are calculated as a percentage. Whenever any of the 
connection settings are changed ensure that the alarm values set are still correct. 

10.13.1  Alarm statistics reset 

This setting is only for the online alarms statistics displayed in the 

QDSP2

 software which 

can show graphically the frequency that alarms occur. 

 

FIGURE 10-12: QDSP2 ALARM SETTINGS 

10.13.2  Alarm Group settings 

M3x5

 supports recording and storing of 32 alarms that are divided into 4 groups of 8 alarms. 

Each group of alarms has some common settings applicable for all alarms within the group. 

10.13.2.1  MD Time constant  

Sets a thermal mode maximum demands time constant for the alarm group. 

When monitoring a quantity it is possible to monitor its actual value or its maximum demand 
value. If the latter is chosen then a time constant for calculation of the thermal mode 
maximum demand value should be set.  

This setting is for alarm purposes only and is independent of maximum demand calculation 
settings for monitoring and recording purposes.
