Powering up the STS for normal operation can be done as follows:
1.
The STS should be left in Normal mode configuration for MCSWs as shown in
, Normal Mode
MCSW Configuration.
2.
Apply power to the STS externally by closing circuit breakers feeding the unit.

When the Ethernet settings are changed on the
Settings
screen (
11.2 Ethernet
), the Monitor must be
restarted. Because the Monitor logic controls transfers, the STS must briefly be put in Redundant Mode to
provide a backup transfer capability to the Monitor:
1.
On the
Home
screen, make note of the existing parameters, particularly
Preferred Source
and the actively
conducting source as indicating by the
yellow line
on the One-line display.
2.
Use the ROI panel key to open the ROI panel.
3.
On the ROI, set the
MODE OF OPERATION
toggle switch to
REDUNDANT
mode.
4.
Login on the
Home
page as Administrator or other higher-level authorization.
5.
In the navigation buttons, touch the
Setup
button to display the
Settings
screen.
6.
In the
Ethernet Settings
panel, touch the
Restart
button to restart the Monitor. Touch the button just
once: the restart will take around 30-45 seconds and it is not immediately apparent that the restart is
proceeding.
7.
When the
Home
screen reappears, do a visual check of Monitor parameters and settings for correctness:
a.
On the dynamic One-line display, verify that the currently conducting source matches the source
indicated by yellow line.
b.
Verify that the
Preferred Source
selector is selecting the currently conducting source. (If the
Preferred Source
selector is not the current source, it will force a transfer when you return to
NORMAL
mode.)
c.
If the
Preferred Source
is
not
the currently conducting source, login on the
Home
screen with at
least operator-level authorization and set the
Preferred Source
selector to the source recorded in step
1.
8.
After validating the Monitor, at the ROI set the
MODE OF OPERATION
toggle switch to
NORMAL
mode.
9.
Close and lock the ROI panel.

If the Monitor fails to transfer the load, the SAS board will take over the transfer. If Alarms appear showing the
SAS board in control, follow these steps:
1.
Check the
Alarms
page for alarms showing the SAS board is in control.
