States - S&C PureWave Operation And Maintenance

States

The DC bus capacitor test points are red, white, and black.
• The black test point is connected to DC (-).
• The white test point is connected to the DC midpoint
• The red test point is connected to DC (+)
Capacitors are connected from DC (+) to midpoint and from DC (-) to midpoint. Use
these test points to monitor the DC bus voltage while the discharge jumper is installed
to verify that the voltage has been discharged to a safe level for entry and service.
Note the locations of the DC test points and the 24-VDC alternate supply points to
avoid confusion.
Listed in Table 1 are the eight operating states of the PureWave CES. The IntelliLink
program will inform the user what state the system is currently in. Depending on the
alarm condition encountered, the community energy storage system can be in any of
these states. Below is the description of each state.
Table 1. Operating States of the PureWave CES
States
Program Reset This state indicates that the program is initialized . This state also only occurs at
power up .
Inhibit This state indicates that there is a problem that needs attention and will affect
the proper operation of the system . The system will stop operating when an
INHIBIT is being displayed on the IntelliLink program . The AC breaker will
remain closed during this state .
Trip Offline This state indicates that there is a severe problem that needs attention and will
affect the proper operation of the system . The system will stop operating when
a TRIP OFFLINE is being displayed on the IntelliLink program . The AC breaker
will be open in this state .
Ready The state indicates that the PureWave CES is ready to protect the load in the
event of a utility disturbance .
VS Run This state indicates that the master control has commanded the PureWave
CES to run . Here, the inverter controls the AC voltage and the PureWave CES
is the power source in the event of a utility power outage .
CS Run This state indicates that the master control has commanded the PureWave
CES to run . Here, the inverter controls the AC current and the PureWave CES
provides the required real or reactive power for power smoothing .
Conserve Energy This state indicates that the battery is reducing power usage to prolong
the ability to run on the battery . This state is entered if the battery energy is
depleted and the utility source voltage is not present .
System Shutdown This state indicates that the battery energy is depleted . The system enters
"shutdown," which turns the system off . The system will return to the "Ready"
state when the utility source power is restored and the batteries are charged .
