3.5.2 H/L Alarm (View H/L alarm)
①
Click on "Process Variables (V)" at top-level menu, select "View H/L alarm", and click on again.
A message box for H/L alarm then appears as shown in Fig. 8.
②
At View H/L alarm, the "H/L alarm status" changes from "No Triggered" to "Triggered" when the selected
item at "H/L alarm vars" of "Status output" reaches "High alarm point" or "Low alarm point," and the
Status output changes from "ON" to "OFF."
In this connection, "H/L alarm status" is valid only when "H/L Alarm" is selected at "Status output func"
.
As long as your option is other than "H/L Alarm," the "H/L alarm status" does not change to "Triggered"
whether or not the setpoint is exceeded, and the status output also remains unchanged at "ON."

Counts up while the fluid flows in the direction (forward) set at "Flow direction."
・
"R-Total"
:
Counts up while the fluid flows in the reverse direction with "Bi Direction" selected at "Status
output func"

・
Diff-Total"
:
Means a relationship "Diff-Total = F-Total−R-Total" and is equal to "F-Total" except "Bi direction"
is selected.
Here, the flow direction indicated on the flowmeter is regarded as "forward direction" when "Flow direction"
is "Forward"
.
The flow direction opposite to the arrow direction indicated on the flowmeter is regarded as
"forward direction" when it is "Reverse"
.
