Commander’s status can be viewed via LED’s located on Commander’s front panel or via a
Graphic User Interface provided as part of Commander’s web services. As some operators may
also want to view current Sensor probe status and not just exceptions, a Sensor Status mode is
provided. Using this mode the front panel probe LED’s will indicate status in the same method as
the probe itself. Actual response will be dependent on your network speed.
Alarm Alerts: Watch Dog Timer Operation
Watch Dog Timer:
Commander contains a watch dog timer that will monitor the internal system. In the event
Commander cannot properly operate for more than two minutes, the system will wait until the
condition no longer exists and reboot itself.
Once Commander reboots, all data will have been lost. Many reboot conditions occur due to poor
main power supplies or fluctuations in main line voltage. As with any other computer device, AFI
strongly recommends the use of back up power supply.
Watch Dog Timer Responses:
If the action is due to poor power or power fluctuations, the Port “B” LED will turn Red
An Email alert “Watch Dog” activated will sent to the address programmed in the Global Settings
when power is returned to Commander. The time will indicate when power was returned.
The first entry in the event log will show as Watchdog with time and date when normal
conditions were restored
