Fault indications
If there is a specified fault condition, the transmitter output changes to the
specified NAMUR alarm level. The alarm level is set by the position of
DIP switch 2 (refer to Table 4-1).
If applicable, the optional display shows an alarm code to help identify the fault.
Table 5-1 shows some of the codes. If there are several fault conditions, the
alarm code is the sum of all the applicable codes.
