Alarm signals
If a particular alarm signal is programmed to cause the system to shut down (e.g. MIN conductivity
limit) or if shutting down is specified (e.g. motor circuit-breaker), the alarm signal cannot be cancelled
in the LCD until the fault has been rectified.
There are some fault alarm signals which permit the system to be switched back on before the fault
has been rectified. The fault alarm signal is cancelled, and the internal delay time for the alarm is re-
set. If the fault still exists once the delay time has elapsed, the alarm signal is repeated.
The system can be switched back on manually in the case of the "External Switch" and "Signal Stop"
signals. The input affected is ignored until the next deactivation sequence.
If the integrated buzzer or an alarm relay have been programmed for a particular alarm signal, the fault
display is not deleted automatically.
Cancel alarm signals by pressing
the button.

The value has been below the conductivity limit
for over 60 seconds.
If the system cut-out has been programmed in
programming step 1.4, it must be switched
back on manually by pressing "ON".
Possible causes: Change in the quality of the
water, air on the measuring probe, interruption
in the power supply to the measuring probe.

Once the delay entered in programming step
1.8 has elapsed, the value is above the max.
conductivity limit.
If the system cut-out has been programmed in
programming step 1.7, it must be switched
back on manually by pressing "ON".
Possible causes: Change in the quality of the
water, the system settings have changed, the
conductivity module is faulty, the measuring
probe has short-circuited.

The "exceeded pressure" input has been acti-
vated. The system has been switched off.
Switch the system back on manually by press-
ing "ON".
Possible causes: The system settings have
been changed, the modules are soiled, the
concentrate flush valve is closed.
Possible causes: No pressure in the untreated
water, the pre-filter is blocked.

The motor circuit-breaker, which is integrated
into the front panel, has been activated.
The system cuts out.
The system can be switched on straight away
by pressing "ON".
Possible causes:
T

been changed
,
faults in the system, the mo-
tor has overloaded.
