10 S&C Instruction Sheet 658-500
In order to clear an alarm condition, the PureWave CES will require a "reset" to set
the unit to the "Ready" state. This enables the community energy storage system to be
ready for another event should one occur. Table 2 lists the three resets available for the
PureWave CES: Auto, Manual, and Self.
Table 2. Reset Types for the PureWave CES
Reset Type
Auto This type of reset will automatically be performed until a pre-determined reset
count has been reached .
The alarm is reset up to the limit defined by the Auto Reset TripCountMax
control parameter . When the number of Auto Reset attempts exceeds the
TripCountMax, the system goes to and remains in the 'Trip Offline' state until it
is reset manually by the operator .
Each alarm does not have its own Auto Reset Trip Counter . Rather, there
is only one counter, such that Auto Reset attempts from different alarms all
count against the same total . There is also an Auto Reset Trip Reset Timer that
starts counting down from five minutes every time an Auto Reset alarm occurs .
If the timer reaches zero before the maximum number of Auto Reset attempts
is exceeded, the Auto Reset Count is cleared . The Auto Reset Count is not
allowed to persist for more than five minutes .
Manual This type of reset will require a person to use the local user interface, a SCADA
connection, or push the RESET button on the control panel of the PureWave
CES to reset the system .
Self This type of reset will clear alarms when the alarm condition clears . No reset
counter is used .
The PureWave CES contains an extensive self-diagnosis system. If any abnormal condi-
tion occurs, the system will activate an alarm. Below is a list of alarms categorized by
alarm type. Alarm types are categorized as information, warning, inhibit, isolate, and
trip offline.
All alarms should be handled by qualified personnel who are knowledgeable in
troubleshooting the PureWave CES . If there are any doubts about how to handle an
alarm event, please contact S&C Electric Company .
