B.3 Deciphering the “FAULT Code” Reading from the BCM (used in
Modulex Boilers)
NOTE
In order to properly interpret a Fault Code for Modulex
Boilers, as displayed in the BCM (Boiler Communication
Module), it is necessary to refer to the table below in order
to determine the actual Fault Code that will be looked up in
the Fault Code tables, A-5 and A-6, on the following pages.
DISPLAYED
NUMBER
FAULT
NAME
FAULT CODE FORMULA
0 No Fault None
Between
1 and 255
BMM #0 Fault Displayed Number = BMM Fault Code in Table A-6
Between
256 and 511 BMM #1 Fault Subtract 256 from Displayed Number = BMM Fault Code in Table A-6
Between
512 and 767 BMM #2 Fault Subtract 512 from Displayed Number = BMM Fault Code in Table A-6
Between
768 and 1023 BMM #3 Fault Subtract 768 from Displayed Number = BMM Fault Code in Table A-6
Between
1024 and 1279 BMM #4 Fault Subtract 1024 from Displayed Number = BMM Fault Code in Table A-6
Between
1280 and 1535 BMM #5 Fault Subtract 1280 from Displayed Number = BMM Fault Code in Table A-6
Between
1536 and 1791 BMM #6 Fault Subtract 1536 from Displayed Number = BMM Fault Code in Table A-6
Between
1792 and 2047 BMM #7 Fault Subtract 1792 from Displayed Number = BMM Fault Code in Table A-6
Between
2048 and
65279
Invalid Codes None
