Totalizer
Number of Totalizers:
Up to 32 totalizers,
15 digits with comma separator
Totalizer Inputs:
Calculates total based on selected rate channel,
pulse input, digital input, or triggered event for non-rate channels.
Total is stored in non-volatile memory if power is lost.
Maximum Total:
18 digits, 999,999,999,999,999,999
Rate Channel Input:
4-20 mA input, Pulse input, Modbus input
Rate & Total Decimal Point:
Independent and user selectable
from 0 to 15 places
Totalizer Reset:
Via front panel keys or digital inputs
Non-Resettable Total:
Total may be set up to be non-resettable
to prevent unintentional reset. This can be changed in the Setup
Totals menu.
Total Units Conversion :
Input: Rate channel
Total units may be different than rate units. Use the custom units to
convert to any unit (e.g. Gallons to MGal: Factor = 0.000001)
Pulse Input K-Factor:
K-Factor = pulses/units of measure
Calculates total directly from pulse input, Modbus input, channel,
total, or Modbus output. Create rate channel by entering K-Factor,
units and time base in sec, min, hr, or day. Decimals: 0 to 15
Count Down:
Total can be set up to count down from a
predetermined value entered by the user.
Preset Value:
Enter the preset value to count up or down.
Reset total sets total to the preset value; to reset to zero uncheck
the Preset box.
Roll-Over:
Enter the value for total to roll-over to 0
Example: Roll-Over = 1,000,000
Total goes to 0 after 1 million
Negative Total:
Allow total value to count below 0 for bi-directional
flow based on rate channel
Total Bargraph:
Bargraph can be scaled to represent the expected
maximum total.
Function Keys:
Screen Setup: Assign F1-F4 to Reset Total,
Enter Total, Add To, or Remove From total
Previous Total:
This is the total prior to the last reset. Multiple
previous totals can be set up by selecting a previous total as the
input to a new total. The date & time is captured with the previous
total.
Daily Total:
This is the total for the day, starting at midnight. Daily
total can be the input for previous totals to keep a record of a few
days. The date is captured with the previous total.
Grand Total:
Uses another total as the input and it is set up as
non-resettable
Non-Rate Total:
This total takes the input from a non-rate channel,
a trigger causes the total to increment or decrement based on the
settings selected (e.g. Input from weight scale added when digital
input is triggered).
