Example of low alarm setup
Given below is an example of setting up the low alarm for alarm .
●
Setup example (where "alarm hysteresis" and "alarm immunity duration" are involved.)
・
Alarm conditions : When the following condition continues beyond the alarm immunity time.
Lower limit of alarm immunity zone < Instant flowrate <Alarm setpoint
・
Alarm cancel conditions : Instant flowrate
≦
Lower limit of alarm immunity zone
or Instant flowrate > Alarm Se Alarm hysteresis

NOTES: When alarm status (lower digit) is set to "o", the "ON" and "OFF" of alarm output become
the opposite states shown in the above figure.

Setup example (where "alarm hysteresis" exists and "alarm immunity duration" is set to "0".)
・
Alarm conditions : Lower limit of alarm immunity zone < Instant flowrate <Alarm setpoint
