The ROI panel is in a covered compartment just below the touchscreen display. Login is not required to use the
ROI; key access provides security.
The ROI panel is
always active
: the toggle switches are enabled and the LEDs are valid in both Normal and
Redundant modes (see
for an explanation of LEDs and toggle switches).
The ROI panel has these functions:
1.
1. The ROI panel sets the operational mode of the STS, either Normal or Redundant Mode (see
a.
The
MODE OF OPERATION
toggle switch should be left in
NORMAL
except for rare circumstances.
b.
When the
MODE OF OPERATION
toggle switch is set to
REDUNDANT
, both the ROI panel and the
touchscreen display are active, if the Monitor and display are operating properly, but the SAS board
controls transfers, not the Monitor. Redundant Mode is required, for example, when the Monitor must
be restarted, because it provides a backup transfer capability while the Monitor is restarting.
Circumstances requiring Redundant Mode are rare and time spent in Redundant Mode should be
brief.
2.
In Normal Mode, the ROI panel automatically backs up
a.
the display, providing a means to manually transfer the load if the touchscreen is not functional, and
b.
the Monitor logic, if Monitor logic fails. The SAS board is always in standby mode, providing
continuous backup to Monitor logic and the display.
3.
In
REDUNDANT
mode, the ROI can also be used to directly initiate a transfer using the
SOURCE
SELECTOR
momentary toggle switch.
