3.8 Wall Mount Hub Unit Operation
3.8.1 Hub Unit Status LEDs
The following status LEDs are mounted on the front panel of the Hub Unit as shown in Figure 9:
Figure 9: Monitor Hub status LEDs
The functionality of these status LEDs is as follows:
 Monitor Health: This green LED will flash while the system is starting up, and will be lit
solidly while the monitor is functioning.
 Alarm/SCADA: These LEDs indicate the state of the Alarm and SCADA Output contacts.
These are normally in the “Clear” state (Section 8.1) and the corresponding LED will NOT be
illuminated. If any of the contacts change to the active state, or an Alarm condition is
detected, the corresponding LED on the front panel will light red. The following
functionality is preprogramed for each output:
o
Alarm: LED will illuminate (or output will switch to an Alarm condition) when any
alarm is raised on the Monitor.
o
SCADA Output 1: LED will illuminate (or output will switch to an Alarm condition)
when a Red threshold alarm is raised.
o
SCADA Output 2: LED will illuminate (or output will switch to an Alarm condition)
when an Amber threshold alarm is raised.
o
SCADA Output 1: LED will illuminate (or output will switch to an Alarm condition)
when a Health alarm is raised (including sensor disconnect).
There are three cases where all SCADA LEDs will illuminate and when all outputs will be
switched into Alarm condition:
o
Red, Amber and Health alarm are raised at the same time
o
UltraTEV Monitor HUB was shut down
o
UltraTEV Monitor HUB software failed to respond
Please refer to Section 12 for information on alarm configuration.
