Total Reset (T Reset) - YOKOGAWA YPP6830-AP0-0 Instruction Manual

YPP6830 Explosion-Proof Pulse Input Rate/Totalizer
Multi-Point Linearization (nopts)
Up to 32 linearization points can be selected under
the nopts function. The multi-point linearization can
be used to linearize the display for non-linear inputs.
Linearization data can be entered using a known
accurate signal source (InP 1-32) and then entering
the desired/corresponding meter reading (dSP 1-32)
for that input signal level. These points are
established via direct entry (SCALE) or with an external
calibration signal (CAL).
Calibration Units (CAL UNITS)
Enter the units associated with the desired scale
values. Selecting the units allows the meter to
perform automatic unit conversions.
Pulse Input Time Unit (Time UNIT)
This is the time component to be used when
calibrating a number of input pulses per time unit to
equal a certain display value.
For example, if the inputs being entered in
pulses/second the time unit would be set to seconds.

Total Reset (T Reset)

This menu is used to select the ways the total and
grand total may be reset.
Manual or Automatic Total Reset
Function (t rST)
For manual reset, select T RESET → t rst → man
and then select whether manual reset will be enabled
(Enabl) or disabled (dsabl) using the Up arrow key.
Press the Enter button to accept. Disabling reset will
avoid inadvertent resets of the total via the front reset
button or external reset contact.
For automatic reset, select T RESET → t rst → Auto
→T DELAY and enter reset delay time in seconds.
The automatic total reset works together with an open
collector alarm assigned to trigger on a total set point.
Once the output alarm total set point is reached, the
meter waits for a programmed amount of time (T
DELAY) and then resets the total to zero.
This feature can be used for automatic batch control
applications.
Time of Day Total Reset
For timed reset, select T RESET → t rst → Time
→T RESET and enter the time of day at which the total
should be reset. The total value will be reset every
day at the specified time.
Press the Enter button, at any time, to accept a
setting; otherwise press the Menu button to exit
without saving changes.
Automatic Total Reset & Total Alarm
The T DELAY parameter is used by the NPN open
collector outputs when they are programmed as total
alarms. If total reset (t rst) is programmed to Auto
the time delay (T DELAY) is the length of the
associated Out 1 or Out 2 total alarm prior to the total
being reset to 0.
For information on programming the NPN open
collector pulse outputs as total alarms, see Alarm
Output (alrm) programming on page 33.
