Operation
This section explains how to operate, calibrate, and validate the WMS. It also
explains how to adjust valves, handle alarms/warning, logs, and software
updates.
6.1 Sampling
The WMS can operate in either remote or local.
6.1.1 Remote operating mode
When the WMS is in remote mode, it is possible to start the sampling via
MODBUS.
Example: Send 1 to Modbus Address: 40000.0
The system will start when the remote start delay period has expired.
Example: Send 0 to Modbus Address: 40000.0
The system will stop sampling by turning off the pump or motor valve
Follow the MODBUS map in section 5.3.2 to identify relevant functions.
6.1.2 Local operating mode
When the WMS is in local mode, it is possible to operate the system
manually. This mode can also be used to block remote start signals when
performing some types of work on the system. To test the system, it is
possible to start the pump or open the motor valve by pressing the “running/
stopped” slider in the upper left corner.
When operating the system manually, it is important to pay attention to valve
positions, open sensors/unmounted sensors, pressure, and flows.
ATTENTION
If the web viewer is activated and in use, it is important to turn off the web
viewer before carrying out work on the system or pump, otherwise there is a
risk that the system can be started from the web viewer.
