User-Defined Alarms
General Description
EcoStruxure Power Commission Softwareenables the configuration of 10 user-defined alarms that can be chosen from a list of 150 predefined alarms.
Each user-defined alarm has a corresponding user-defined alarm number (201–210) and a corresponding alarm code (see next paragraph).
Each alarm has a priority level that manages the alarm display on the FDM121 display:
-
no priority = N/A (not affected)
-
low priority = 1. No alarm display on the FDM121 display.
-
medium priority = 2. The FDM121 display LED is steady ON.
-
high priority = 3. The FDM121 display LED blinks and a pop-up screen informs the user the alarm is active.
Refer to the ComPact NSX MicroLogic 5/6/7 Trip Units - User Guide Related Documents for more information regarding the relationship between alarm priority and FDM121 display.
The settings of the 10 user-defined alarms are in the user-defined alarms registers:

User-Defined Alarm Record
A read request of 12 registers is necessary to read a user-defined alarm record.
The order and the description of the user-defined alarms records are the same as that of user-defined alarm record 1:

The MSB gives the activity of the alarm: 0 = On, 1 = Off. The factory setting is 1 (Off). The LSB gives the priority of the alarm: N/A, 1, 2, or 3. The factory setting is N/A (no priority). |

(1) The value of the measurement identifier is the register number of the measurement. For example, the measurement identifier of current on phase 1 (I1) is 1016. (2) The unit of the threshold depends on the measurement identifier. For example, if the measurement identifier is I1, then the unit is A. |
