5. Enter a value that represents the magnitude of each pulse output in the
Units/Pulse textbox.
6. The following fields are for display purposes on this screen, though their data may
be used in other processes. These fields are not configurable by the user.

Threshold Unit – The unit of measure associated with the Input. The
Threshold Limit should use the same units.

Totalizer Value – Displays the current value accumulated by the totalizer since
it was last cleared. When a totalizer is active, the value updates every second.
Any flow that occurred while the totalizer was disabled or inhibited is not
included in the value, nor is any flow that occurred when the input value was
below the Threshold Limit.
Note: The Totalizer Value will roll over at 1,000,000.
All Totalizer
Choosing an action state from the Selection dropdown under All Totalizer at the
bottom of the Totals tab will apply the selected state to any of the configured totalizers.
– Disable – The Disable state in the All Totalizer Selection dropdown sets all four
totalizers to a disabled state. In a disabled state, the totalizer values stop
accumulating, even when the values of the inputs are greater than or equal to the
threshold limits. If a totalizer has not been previously enabled, the Totalizer Value
field in that totalizer’s area will be set to zero.
– Enable – When the Enable state is chosen from the All Totalizer Selection
dropdown, all Totalizers in the Inhibit state will be changed to the Enable state.
This allows the totalizers to begin accumulating when the values of the inputs are
greater than or equal to the threshold limits. If a totalizer has been enabled
previously, the Totalizer Value resumes accumulating at the previous value.
– Clear – For all of the totalizers, the Totalizer Value and any associated relay counts
are set to zero when the Clear state is selected. The totalizers then return to their
previous state of disabled, enable or inhibit.
– Inhibit – When Inhibit is selected from the All Totalizer Selection dropdown, all
enabled totalizers will change to an inhibit state. All totalizers that are in the
Disable state will stay disabled.
