6.1.4 Setting Burnout Function “nAMU”
Operation: Hold down the [MODE] key for 2 seconds, select “nAMU” with the [▲], [▼]
keys, and press the [ENT] key.
Set the burnout function for the primary current output of 4-20 mA DC (compliant with NAMUR).
Select one of the options: No burnout function is “non,” burn-up is “Er.HI,” and burn-down is “Er.
Lo.”
Figure 6.5 shows an example of setting burn-up.
NOTE : Burnout is a function compliant with NAMUR that allows increasing/decreasing the
current output to the high/low limits in the event of a failure. Burn-up allows increasing the
output to the high limit of 21.0 mA and burn-down allows decreasing the output to the low
limit of 3.6 mA. The burnout function works in the event of an error (when the FAIL contact
output closes).
