2. On the task bar, click Operate>File Utilities>Save and Restore Utility.
3. Click Save Station Files .
4. Select the file path to store a copy of the configuration. The destination directory may look like this: C:/PCCU32/Station
Files/Station Name/.
5. Select the All Setup or Configuration Files box. Do not change either the Extension List or the From location.
6. Click OK . This may take a few minutes to complete.
IMPORTANT NOTE: If the save and restore function has been performed at a prior time, the program may state
that the files already exist and ask if the user would like to Overwrite/Merge or Rename the existing file to a
backup file. Choose preferred method.
7. Click Yes when prompted to copy the files to the S Drive. The Upload Completed! screen will appear.
IMPORTANT NOTE: The Destination Directory is now the Source Directory. This it is the location where the
station files are saved on the computer’s hard drive. The field From location is now called Download To , and the
location is S:\. Do not change this.
8. Click OK .
9. Click OK when the Download Completed screen appears.
Duty cycling power (optional)
Duty cycling allows the host device to turn on power to the LevelMaster, collect data and then turn the power off. For systems
operated using solar and battery power, each LevelMaster draws 1 mA power while idle and 40 mA during the read/collect
function. The cycling is done via a digital output in the host software.
Setup is done in the host software and may be accomplished by setting the suggested parameters shown in Table 8. This
feature is not required and can be enabled or disabled using the cycle option below. It is disabled by default. Example of digital
output pinouts are provided in Figure 54,
Host hardware digital outputs .
Table 8: Duty cycle parameters
Parameter Description Suggested settings
Cycle Option Enables (on) or disables (off) the Duty Cycle option. On or enable
Read Now
Setting this flag to Yes causes the host to initiate an immediate read from all of the
LevelMasters. The flag then returns to the No state. The Scan Time counter is zeroed so that the
next scheduled Scan Time is from the time this read was initiated.
No
Power DO
For the Duty Cycle option to work, the host turns the power on and off via one of its digital
outputs. This parameter assigns the digital output connected. See Figure 54,
Host hardware
digital outputs for connection information.
DO 1
Power Up Time
This is a delay time in milliseconds from when the Power DO is energized until the read request
is sent to the LevelMaster. This allows the LevelMaster to stabilize after power-up before
requesting data.
1000 ms
Rd Freq.
This is the frequency the flow computer will read data from the LevelMaster in minutes. If the
Cycle option is turned on, this Rd Freq. (scan time) overrides the Rd Freq. under the individual
tank setups. If the Duty Cycle option is not enabled, the read frequency is established by the
Scan Time in individual tank setups.
60 minutes
Rd Timeout
This is simply a counter that counts down to the next time data is requested from the
LevelMaster. It is based on Rd Freq. above.
Not applicable
Additional parameters located on some screens may not be used for enabling and scheduling power cycling, for example: Push-
to-Read, Read Now DI and Round To parameters. These may be used and set at other times.
IMPORTANT NOTE: See the Contact us information on the back of this manual for support with this
configuration.
