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.
