In the Figure 29 example, Schedule 4 is set to start two hours after Schedule 3,
but schedule 3 is set to use Power Prole 3, which has a duration of four hours. As
a result, Schedule 3 overruns into when Schedule 4 should be running, creating a
system conict. Make sure a proceeding schedule is set to start after a preceding
schedule has nished. This will ensure the system throws no errors and can be
used correctly.

Misconfigured/
Erroneous Setup
If the Week Schedule is congured incorrectly, the system will show that the schedule
has been miscongured or that there is some format error.
Misconfigured
Weekly Setup
The system will note the day the misconguration occurred. Go to that page to
investigate what went wrong. Figure 29 shows a system where the Sunday schedule
was miscongured. The page shows “Miscongured Schedule on Sunday” in red font
to make it stand out.

User Interface The PureWave SMS-250 can be controlled through the user interface located at the top
left side of the unit. Figure 5 shows the controls available on the user interface.
Figure 5. User interface.
The controls on the user interface are as follows:
SMS CONTROL−This switch enables the user to switch control from SCADA mode
(SCADA ENABLE) to HMI mode (SCADA DISABLE) and vice versa.
RESET−This black pushbutton, when pressed, enables the user to administer a manual
reset.
INVERTER STOP− This red pushbutton, when pressed, enables the user to stop any
running operation. Pushing this button will open the ac and dc circuit breakers.
WEB SERVER CONNECTION−The user can use this connection port to connect locally
to the system via Human Machine Interface (HMI) mode.
PRE-CHARGE−This key-lock is used when any work or maintenance requires the
inverter to be de-energized. When the inverter stop pushbutton is pressed and the
pre-charge key is turned to the OFF position (ac and dc circuit breakers are open), the
inverter bridge will discharge to a safe level in 5 minutes.
WARNING
Capacitors in the PCS may have residual charge after the pre-charge key has been
turned off. If there is no load connected to the unit, wait 5 minutes for the capacitors to
discharge before proceeding with work or maintenance.
When the pre-charge key-lock is in the OFF position, the key can be removed. The
inverter bridge will remain de-energized until the key is inserted and turned to the
ON position (and source power is restored). Once the key-lock is in the ON position,
the key cannot be removed unless it is turned back to the OFF position.

A prole for charging for two hours at 250 kW and then immediately discharging for
two hours starting at 250 kW and ramping down to 0 kW would be as follows. (Note:
The system would linearly reduce the discharge power from 250 kW to 0 kW over a
two-hour period, so at one hour the discharge power would be 125 kW.)
1. Starting Power: -250 kW
2. Section 1 Duration: 120 min
3. Section 2 Power: -250 kW
4. Section 2 Duration: 0 min
5. Section 3 Power: 250 kW
6. Section 3 Duration: 120 min
7. End Power: 0 kW
After creating the desirable profiles to use, configure the days and times the
particular profiles should run within the Week Setup screen.
Note to User: If the schedule ends in a value different from 0 kW, the schedule
will keep (in the case of the Profile 2 example) discharging until it runs out of
battery power or meets another schedule. To command it to stop, change the power
mode to Commanded Power at 0 kW.
Figures 25 and 26 on page 21 show examples of how the profiles can be created
and seen graphically in any desired fashion. S&C recommends creating different
charging profiles in Profiles 1-10 and different discharging profiles in Profiles 11-20,
each having an End Power value of 0 kW to ensure the system sits in idle—neither
charging or discharging—at the end of a schedule.
