Two set points SP1 and SP2 can be programmed to suit different applications The actions of either or both set points can inverted if required For normal operation the set point output is active until the input reaches the set point level In this condition when the input value is less than the set point the SP indicator is on and the output relay is energised producing a closed circuit on a normally open contact When the set point value is reached the SP indicator is off and the relay is de energised producing an open circuit output For an inverted operation the reverse conditions apply Normal and inverted action is determined by the direction of the input value as it changes For example In alarm applications A High High operation allows for a rising input value to operate on two set points A Low Low operation operates 2 set points on a falling value A High Low operation will operate on a rising or falling value setting a band by one set point operating normally and the other being an inverted action 19 Mantracourt Electronics Limited ADW15 FPT User Manual In Flight Compensation The setting of an In Flight value causes the set points to cut off early to control the flow of the material being weighed For example if SP1 is used to control a flow a certain amount will be In Flight between the supply point and receiving point causing a positive error when the required weight is reached The In Flight compensation value
