Independent Alarm A1.tP. indE = (ASV min =beginning of scale ASV max =end of scale)) SV=Set point of CONT output

Deviation Alarm A1.tP. DE. ASV min. =-300, ASV max. = +300) (If , inP Pt..0 = ASV min. = -30.0,ASV max. = +30.0) ASV = ASV = Set point of alarm output

Band Alarm = A1.tP. bAnd SV =Set point of CONT output ASV = Set point of AL1 output (ASV min. = 0, ASV max. = +300) (lfinP = Pt..0,ASV min.=0.0,ASV max.=+30.0)

Band Alarm With Inhibition SV =Set point of CONT output ASV = Set point of AL1 output (ASV min. = 0, ASV max. = 300 ))

First, press and holdj key, alarm setpoint value appears on the display. Then, the value is adjusted by usingAlarm1 and Alarm2 setpoint values can be adjusted in sequence when per press

NOTE: The maximum of is the value of parameter and the minimum of it is the value of parameter.
If independent alarm is selected, A1.SE. and values can be adjusted between the limits of the full scale.
If deviation alarm is selected, A1.SE. and A2.SE. values can be adjusted between - and + .
If band alarm is selected, A1.SE. and A2.SE. values can be adjusted between 0 and +300.
