Alarm parameters are used to define the alarm limits used in the Analyzer and displayed in the reports.
|
Custom alarms may be replaced by the system’s default template during upgrades. |
Edit and add alarms
|
If alarms are to be available in multiple parameter sets, they must be created in each parameter set or added using an SQL script. Contact Digpro for more information. |
|
The Unique ID and Parameter ID fields are created automatically when the alarm is saved and cannot be edited. |
•To edit an existing alarm, select a row and press Edit.
•To create a new alarm, press Add. A blank form opens where you can specify the alarm’s properties.
a.Enter a value for Alarm type.
b.Specify the voltage level for which the alarm applies using Upper voltage, Lower voltage, Operator UE, and Operator US.
c.Select an Alarm value, such as A or B. The alarm value is retrieved from the codelist Categories for alarm / ALARM_CATEGORY_CL. By default, an A alarm is more serious than a B alarm, but the severity level and color are determined by the alarm category in the codelist. See section Edit alarm categories.
d.Select the type of result to be monitored under Measurement type. This affects the unit used for values A and B; for example the Voltage drop is measured in percent, but Energy read is measured in kWh.
e.If the alarm is to be triggered within a range, for example, a voltage drop between 3% and 5%, define the range using Value A, Value B, and the respective Operator.
f.If, instead, the alarm is to compare two different result values, for example, calculated voltage drop and maximum allowed earth potential rise, select the second value under Measurement type 2. How the values are to be compared is specified by Operator A.
Example 1 - Alarm for Energy read
Create an S-alarm for energy consumption in a low-voltage grid when the energy value is between 25,000 and 50,000 kWh.

Edit alarm categories
The alarm categories and their colors are managed in the codelist Categories for alarm / ALARM_CATEGORY_CL.
1.Select Administration > Codelists > Codelist manager.
2.Select the code list owner Network calculation (NETCALC).
3.Select the code list Categories for alarm / ALARM_CATEGORY_CL.
4.Add a new entry 
or select an existing entry and press Edit row 
.
5.To select a color, in the Color code field, press Select color.
6.Select the desired color and press OK. In the codelist manager, the cell in the Color code column will display the selected color.
