  • Page 47: Exception Responses And Exception Codes

    Model FL3102 Exception Responses and Exception Codes In a normal exchange, the master device sends a query to the FL3102. The FL3102 receives the query and returns a normal response to the master. If a normal communications error occurs, there are 4 possible responses from the FL3102: 1.

  • Page 48: Exception Responses

    All the Function Codes have a most-significant bit (MSB). In an exception response, the FL3102 sets the MSB of the function code to a one (1). With the function code’s MSB set, the master can recognize the exception response and can process the data field for the exception code from the FL3102 response message.

    It is always important to begin a series of flame detector checks with a fully charged TL103. Stand within 10 feet (FL3102) from the unit to be tested and aim the TL103 directly into the detector windows. Press the ON button and be sure the high intensity pulsing beam strikes the detector face squarely.
