The ALM1 indicator will not light while the END output is set.(When the “program pattern” parameter is changed from STOP or CONT toOFF, the “alarm 1 output assignment” parameter will automatically be initialized to ALM1.) The output assignment parameters can also be used to assignthe program END output to any output.The program END output is also provided in communications status.Clearing the Program End StatusThe program END output and display will be cleared when the “program start”parameter is changed from STRT to RSET.
The setting is changed from STRTto RSET while the “program start” parameter is displayed.The program END status can also be cleared using an event. If the programstart function is assigned to an event, however, the program end status cannotbe cleared from the “program start” parameter display, which will function onlyas a monitor display.Operating ProcedurePerform the following procedure to use the simple program function.In this example, the program pattern will be set to STOP, the soak time to10 min, and the wait band to 3.Wait band = 3Set pointPVRSET → STRTSoak time = 10 minSTOPEND displayEND output107Using the Simple Program FunctionSection 4-15Operation LevelC25PV/SP100Initial Setting Levelin-tInput type1.
