Description of the signal inputs/outputs
Switching of the signal inputs
Switch the signal inputs "Stop", "WM" and "Ext. Ack" only with
isolated contacts!
Switching with external voltage will damage the device!
Stop input
The stop input is intended for short-term suspension of operation,
e.g. when performing renewal work on softening plants, reverse os-
mosis or other water treatment systems. Generally speaking, the
system is not offline for more than six hours. The renewal phase of a
softening plant, for example, lasts three hours at most.

Stop
External analysis
stop (e.g. via flow
monitor or process
control)
If stop input is active, an analysis is prevented from starting, due for
example to an interval having elapsed. This may be required, if the
system lacks water. However, any analysis already started will not be
suspended. The analysis is completed and the device reverts to
pause mode.
Manual start has priority over stop input. That means that manual
analysis can still be started even when stop input is active.
Where the stop signal is present, the measurement value is shown
on the display and the LED pause flashes. If the stop signal is delet-
ed, a new analysis starts immediately.
Accordingly, a short impulse on the stop input can help trigger an
analysis remotely.
