Basic Operation
The following describes how the user can operate the PureWave SMS-250 system
using HMI (
SCADA Disable
) and SCADA (
SCADA Enable
) modes. Toggle the SMS
CONTROL switch on the user interface to select the desired mode.
To Trip the PureWave SMS-250 System Offline
To stop the storage-management system, the user can push the INVERTER STOP
button located on the user interface. The
Trip Offline
state can also be activated as
follows:
• HMI: On the PCS user interface, toggle the SMS CONTROL switch to the
SCADA
DISABLE
setting. Then, on the
Command-Control
HMI screen, under the
System
Control
menu, click on the
Trip Offline
radio button for the PureWave SMS-250 to
go to the
Trip Offline
state.
• SCADA: The user can select the DNP Point 0 (Trip Offline) to pulse on a request for
the PureWave SMS-250 to go to the
Trip Offline
state.
Starting the PureWave SMS-250 System
To start the storage management system, if the INVERTER STOP button on the user
interface was pressed, the button will need to be twisted and released to its not-pressed
position for the system to go to the
Ready
state (barring any other
Trip Offline
or
Inhibit
alarms). If the INVERTER STOP button was not pressed, then either of the
following actions can be taken:
• HMI: On the PCS user interface, make sure the SMS CONTROL switch is in the
SCADA DISABLE
postion. Then, on the
Command-Control
HMI screen under the
System Control
menu click on the
Online
radio button for the system to go to the
Ready
state.
• SCADA: If the SCADA
Trip Offline c
ommand is set, the user can clear the bit at DNP
Point 0 (Trip Offline) to latch off the
Trip Offline
request for the PureWave SMS-250
system to go to the
Ready
state.
