20mA) When the display reaches 0 percent the analog output would be 4mA.

The limits can be moved or reversed (HI=0 and LO= 80.0), in this case when the display reads 0 , the analog output would be 20mA and when the display reads 80, the analog output would be 4mA.

The Fail Safe option (FS) controls the action of the analog output when the display goes into over-range (EEEE or –EEEE). In some cases, the low limit or high limit are reserved for error conditions. With set to ‘HI’, the output will run to the 20mA value when over-range or under-range occur. With failsafe set to ‘LO’, the output will run to 4mA at over-range or under-range. With failsafe ‘Off’, the output will go to the defined limit ends. (-EEEE would be 4mA and EEEE would be 20mA typically.)
