INFO
You can also create custom alarms for the input/output configurations for both analogue and digital terminals.
Limitations
There are a few limitations to the customising of alarm parameters. These are stated below.
Table 4.1
Alarm parameters that cannot be customised
Not customisable Notes
Additional alarms
The list of alarms is fixed, and you cannot add more alarms.
If an alarm is not available, you can set it up in CustomLogic. However, it will not be part of the alarm
list, or the alarm management system.
Certain alarms
Some alarms cannot be disabled. For example, the Phase sequence error protection (which prevents
synchronisation when the phase sequence is not the same on either side of the breaker) is always
Enabled.
Certain alarm actions
You cannot change certain alarm actions. For example, for Voltage or frequency not OK, the action is
always Block, to stop the breaker from closing.
Additional alarm actions
You cannot create additional alarm actions. You can only choose alarm actions from the list of alarm
actions.
You can set up responses to operating values or conditions in CustomLogic, but these will not be
available as alarm actions to the alarms.
Inhibits that are not
configured for the
controller type
You cannot add more inhibits to the list of inhibits available for selection for the controller type. For
example, for a GENSET controller, you cannot select the Tie breaker closed inhibit, as this is not
applicable to the GENSET controller.
However, there are three custom inhibits for each controller. You can activate a custom inhibit using a
digital input, Modbus, and/or CustomLogic.
Change the Trigger level
for certain alarms
Most alarms have a fixed Trigger level. For example, Busbar over-voltage is always a High alarm, while
Busbar under-frequency is always a Low alarm.
4.2 Alarm parameters
4.2.1 Overview of alarm parameters
You can configure alarms by adjusting the parameters in the controller. Each alarm parameter is explained in detail in the following
sections. Some alarm settings are not configurable and these are not shown for some alarms.
