6F8A0917- 101 -8.2.17 Flow Rate High/Low limit AlarmThe flow rate high/low limit alarm is the function to generate an alarm when the instantaneous flowrate exceeds a preset high limit value (or low limit value).When an alarm is generated, an alarm message is displayed and a signal can be output through DO.Two outputs are provided each for high limit value and low limit value (4 outputs in total of high limit,high-high limit, low limit and low-low limit) and an alarm output can be sent out separately.The following parameters can be set here:(1) High limit alarm On/Off(2) High limit value(3) Low limit alarm On/Off(4) Low limit value(5) High-high limit alarm On/Off(6) High-high limit value(7) Low-low limit alarm value On/Off(8) Low-low limit valueNote• To output a high/low limit alarm through DO, it is necessary to set the DO function for output.For how to set the DO function, see 8.2.14 “Digital I/O Function.”High/low limit alarm On/OffWhether the high/low limit alarm is used or not can be selectedSelection Alarm operation1: ON Alarm function providedIf the flow rate exceeds a selected high limit value (or low limit value),an alarm is generated.2: OFF Alarm function not providedThe selected alarm will not be generated.High/low limit valueA flow rate value (high/low limit value) to generate an alarm is set in percent of the maximumrange (Range 1) flow rate value.The high/low limit alarm value can be set within the range of −10% to 110% in increments of 0.5%.
