On Board Temperature Sensor Priority.
High Priority:
1. Only local sensor configured & even if
any one of the on-board temperature
sensor is in alarm
2. Only Remote sensor configured & TR40
sensor connected to sylk addr 2 is giving
null value.
3. configured as multi sensor & both the
remote sensor & on-board configured
sensor has failed.
Medium priority:
1. Configured as Multi sensor & only the
on-board sensor has failed. but getting
reliable value from the sylk sensors.
2. Configured as multi sensor & only one
of the sylk sensor has failed with values
available from other sylk sensors (If
configured) or on-board sensor.
When a valid network temperature is
available, then the high priority alarms will
be considered as medium priority alarm.
