Menu
This menu is available on both the WCT400 and WCT410, if the data logging option has been
purchased. This is indicated in the model code by the letter U at the end of the model code. This menu
allows you to save data from the controller to a USB flash drive.
The controller has four logs, the Current Datalog, the Backup Datalog, the Event Log, and the Reset
Log. All files are in a CSV format that may be opened in a spreadsheet such as Microsoft Excel.
Current Datalog
Contains the following data taken at 10 minute intervals:
Conductivity
Temperature
Water Meter 1 Total
Water Meter 2 Total
When the current datalog is downloaded to a USB stick, it is erased and a new log file is started.
If the current datalog is not downloaded before it reaches its maximum size (at least 60 days of
data) the oldest data is overwritten by the newest data.
Backup Datalog
Contains the same data as the current log but it is never erased. When the backup log reaches its
maximum size (at least 60 days of data), the oldest data is overwritten by the newest data.
Event Log
Contains columns for each relay and flow switch input, as well as the date and time. Each time
any of these change state, the date and time is updated and it will show a 1 if the relay is on and 0
if it is off, and a 1 if the flow switch indicates no flow, 0 if there is flow. Tens of thousands of
events will be recorded before the oldest data is overwritten by the newest, the number varying
with the controller’s configuration.
Reset Log
Consists of time stamps of when power was lost, when it was returned, and the cause of the reset.
