5.3 Description of Function Codes
5-180
■ Selecting light alarm factors
To set and display the light alarm factors in hexadecimal format, each light alarm factor has been assigned to bits 0
to 15 as listed in Table 5.3-15 and Table 5.3-16. Set the bit that corresponds to the desired light alarm factor to “1.”
Table 5.3-17 shows the relationship between each of the light alarm factor assignments and the LED monitor
display.
Table 5.3-18 gives the conversion table from 4-bit binary to hexadecimal.
