thealarmsetting,thefollowingfouroptionsareavailable:Noalarm“oFF,”high/lowlimits“ALL,”high
limit alarm “AL.HI,” and low limit alarm “AL.Lo.” If the high and low limit values are reversed or the set
value is larger than 100%, an input error occurs and the setting is not accepted. Furthermore, the DO
