 To provide a commissioning interface and the option for a permanently mounted display there is an Altronic Web Interface (AWI) now available. How to connect and operate the AWI is available in the link below. No need to install any third part programs or deal with windows operating environments. This AWI solution is browser based, operates offline, has pre-built screens ready to go, and is customizable by the user to display the data how and where they want.

+===== - THERMOCOUPLE ALARMS =====
+All of the thermocouple inputs have an alarm set point that is configurable. When using the dual bank system this includes the thermocouples on the auxiliary board. Additionally there is an alarm for the differential of thermocouple 3 minus thermocouple 2 for critical safety of the catalyst.
+{{:documents:afr-500:thermocouple_alarms.jpg?nolink&400|}}
+In conjunction with the alarm set points are three different type of alarm indicators.
+  * Non-latching registers that when mapped to the AWI appear as an LED and turn off after the fault condition has cleared
+  * Latching registers that when mapped to the AWI will appear as an LED and stay on even after the thermocouple is no longer in the fault condition
+  * A digital output signal attached to LS Digital Output 1 that latches on a fault condition
+To clear all of the alarms, regardless of a single or dual bank system, there is one ALARM ACKNOWLEDGE register.
