d) Flow Alarm Action Delay (Numerical entry)
The Flow Alarm Action Delay is a time in seconds that the Flow Rate
value remains above the High limit or below the Low limit before an
Alarm condition is validated. Valid settings are in the range of 0 to 3600
seconds (default value is 0, no delay).
e) Flow Alarm Action Latch (Tabular entry)
The Flow Alarm Action Latch settings control the Latch feature. If
optically-isolated output is assigned to the Flow Alarm Event, in some
cases, the Flow Alarm Latch feature may be desirable.
The following settings are available: Disable or Enabled. By default, the
Flow Alarm is non-latching. That means the Alarm is indicated only while
the monitored Flow Value exceeds the specified set conditions.
5.3.7 Submenu “Totalizer #1”
TIO provides the user with two independent Programmable Flow Totalizers. The
total volume of the flowing fluid is calculated by integrating the actual instanta-
neous fluid flow rate with respect to time. Totalizer #1 (main Totalizer) value is
stored in the EEPROM and saved every 1 second. In case of power interruption the
last saved Totalizer value will be loaded on the next power on cycle, so the main
Totalizer reading will not be lost. Use the “Totalizer Menu” to navigate to the
“Totalizer #1” menu option.The following settings are available for Totalizer #1
(see Figure 5.7):
a) Totalizer #1 Mode (Tabular entry)
This option determines whether Totalizer #1 is Enabled or Disabled. The
following selections are available: Enabled or Disabled. The default entry
is Disabled. Totalizer #1 Mode selections can be set with the UP and DN
buttons and are accepted by pressing the ENT button.
NOTE: For Flow Meter function the value of the High Flow Alarm
must be more than the value of the Low Flow Alarm.
