6 Function Check
A function check might be required for one of the following reasons:
■ Initial startup
■ Routine function check
■ Suspicion of monitoring system malfunction
■ Modification of monitoring system (e.g. integration of additional sensor or device)
■ Change of measuring point / location
Depending on the application (water composition), the sensors connected and the environmental conditions a
regular function check (weekly to monthly) is recommended.
Information on the function check of the connected probes and sensors can be found in the respective manuals.
The function check of the monitoring station itself includes the following steps (see also section 8 for typical error
patterns):
■ Check if any leakage is visible on the flow cells or hose connections / screw fittings.
■ Check and clean the strainer of the inlet filter (see chapter 7.2).
■ Check the flow rate at the outlet of the station (> 0.4 l/min or > 24 l/h).
■ Check the correct function of the flow detector display on the operator terminal. To do this, interrupt the
flow and check whether the display changes to error.
■ Check for possible air bubbles inside the monitoring station.
■ Check whether the flow is constant.
■ If a pressure sensor is used, check if the display on the operator terminal is correct and that the display
shows 0 bar when the inlet valve is closed.
