17.3. Restarting
Restarting is to be carried out like the original start-up. Follow all steps described in
this manual.
Before opening the water inlet, make sure that the flow is not impeded or interrupted
anywhere. When using assemblies that can hold several sensors, make sure that all
holders are occupied or closed with a blind. Make sure that all valves are in the right
position (for example, inlet and outlet open, sampling point closed). Check that all
screw connections are sealed tight before applying pressure.
pH measurements have to be calibrated at the beginning. Mind that the temperature
has to match that of the buffer solutions by either placing the temperature sensor in
the buffer or by setting the temperature manually.
After installing the sensors, wait until all measurements are stable, and check if the
measured values are plausible, before activating the controller. Also check all
settings, especially for controller and alarm, and make sure that the feed lines are
properly connected and undamaged.
Use all safety features the instrument provides, such as the alarm relay, the limits,
the dosage check, and the controller stop.
