1. Make the Keeper parameters visible by changing
150 (Show Clock Parameters)
to a value of
Yes.
2. Make sure that the correct date and time are displayed in
.
3. Choose which analog input channel will be used as the input signal to the Keeper. Set up the analog input
channel for the proper analog input configuration. Note that you can also set up an input from an encoder
as the input to the Keeper function.
parameter 380 (Keeper Input Cfg)
to the value that is the input signal you chose for the Keeper
function.
5. Choose the units to be used by the Keeper by changing
to the desired units.
The default is GPM; if you want that unit, you can skip this step. If the option for units is not available, you
can choose to program the engineering units of the drive as the units of the input function. Do this by
selecting User Units for the Keeper Units parameter and programming
the text you want.
6. Modify
parameter 381 (Keeper Max Scale)
to the value to be displayed with the analog input sensor is at
its maximum value. For example, if you are using a 4-20 mA sensor and it produces an output of 0-1000
GPM, then you should configure the analog input to 4-20 mA and set parameter 381 to a value of 1000.
This value should represent the maximum of your sensor.
7. Verify that the Keeper input signal is scaled correctly. Do this through
. This
parameter should be displaying the value the sensor is outputting. Make sure that this value has been
scaled correctly.
8. Configure the times that the Keeper will save data. To do this, decide whether you want the Keeper to save
data once, twice, or three times a day. Program this choice into
parameter 384 (Keeper Save Rate)
. If you
want the Keeper to save data once a day, select 24 hour. Twice a day would be 12 hour; three times a day
would be 8 hour.
9. Program the
exact time that the Keeper will save data. Do this by programming a time value
into
parameter 382 (Keeper Save Time)
. The Keeper will save the total value of the processed variable
every 8 or 12 or 24 hours, depending on your selection in Keeper Save Rate.
10. Now program the rate of the input variable using
parameter 386 (Keeper Time Rate)
. The selection
of this parameter should be made based on the units you are accumulating. For example, if you are
pumping gallons per minute (GPM), program this parameter to minute. If you are pumping liters per
second, program second. The parameter should match the time base of the units you are accumulating.
11. The Keeper is now set up and ready to collect data. The last step should be to reset the records to be
collected. Depending on the order of parameters programmed, you may have false data in your initial
records. To reset the records, navigate to
parameter 801 (Program Number)
and enter a value of 40. This
will reset the Keeper records so that valid data can be collected. The Keeper will collect data until the first
save time that you have programmed into the drive. This data will be saved in a partial data record that
you will be able to determine from the number of minutes accumulated.
12. You can extract the Keeper records from the drive with a USB flash memory device or memory stick. (See
“Storing Keeper Files” on page 47
.) When you extract the data from the drive, it will be presented to you
in a comma-separated file (.csv) that can be opened in Excel. The format of the data will be as follows:
The Date and Time represent the time the data was saved to the record. In this case, the
units of the Keeper function were configured to be GPM. The fourth column then
indicates the number of gallons pumped during the period ending at the Date and Time
indicated. If you were to configure the Keeper to units of LPS, this field would indicate
Liters. The period field indicates the number of minutes the drive was available to run
during that period. The KWHour field allows you to determine what energy was supplied
to the drive during the period.
5.9 Using the Vacon 500x Real-Time Clock and Other Special Features
parameter 150 (Show Clock Param)
to access the functionality of the Vacon 500x real-time clock,
a wide range of features is available. To do this, first change parameter 150 in Level 2 programming mode
to Yes.
5.9.1 Enabling the Vacon 500x Based on Time of Day (TOD)
The Vacon 500x includes two “enable” windows that can control when the drive is allowed to run during the
course of a work day, Monday through Friday, and an additional “enable” window for weekends. To use this
enable function, select the time in your time zone
(parameter 151, Time Zone Setup
) and the clock hour in
24-hour military time for both enable and disable times. The following table shows both weekday enable
functions
