Single Flow Alarm:
NOTE:
Alarms use Filtered Flow Values!
Checking this option opens up input boxes for
Threshold, Latching
and
Invert.
•
Set the
Threshold
to the flow value you require the
transistor to operate.
•
The logic of operation can be adjusted with the
Invert
check box.
Latching: This gives the user three options of None;
High Threshold and Low Threshold.
•
NONE will cause the alarm to be triggered when the
threshold flow is met. The alarm state will then reset
in accordance with the user set Hysteresis.
•
HIGH THRESHOLD will cause an alarm signal to
Latch on when flow is seen above the set value.
•
LOW THRESHOLD
will cause an alarm signal to
Latch on when flow is seen below the set value.
