x Flow Rate Relay configuration permits relay changeover at two
separate flow rates allowing operation with an adjustable switch
deadband. Figure 4.6 illustrates how the setting of the two set
points influences Rate Alarm operation.
A single-point flow rate alarm utilizes the ON> setting slightly
higher than the OFF< setting—allowing a switch deadband to be
established. If a deadband is not established, switch chatter (rapid
switching) may result if the flow rate is very close to the switch
point.
x The Signal Strength alarm does not pertain to the MFX.
x Error Alarm will cause contact changeover whenever an error is
displayed on the MFX flow meter.
