SPECIAL DISPLAY/MALFUNCTION MESSAGES
The following messages are utilizable signals which can be wired as collective malfunction message
or separately to (optional) relays.
After the relay has been switched, you can have it released again by pressing the key. The program
continues the cycle. At the same time the malfunction message on the display is deleted.
Remark: Each of the described messages can be logged with date and time in the INFO
MEMORY if it has been activated in: Setup->System Settings Change->Info
Memory->Recording

PROGRAM NO. 02
START 12.03.09/08:00
ERROR SUCTION
PAUSE WITH ENT
********************
1. Error SUCTION
The device tried two times running to extract a sample, however,
without success. Thereafter the opposite message is displayed.
Possible causes could be that e.g. the suction hose has not been in
the water, has been clogged or that there has not been any water.
Anyway, the program is continued and the sampler tries again to
extract a sample according to the programming.

ERROR ELECTRODES
PAUSE WITH ENT
********************
2. Error ELECTRODES
If the apparatus displays this message immediately after it has
started to draw-off the sample, the level electrodes are either so
dirty that

no conductivity can be measured or
 the electrodes are permanently bridged.
 Furthermore it is possible that the value „conductivity“ has
been adjusted too sensitive in the service menu so that there
is a permanent signal.

VOLTAGE LOSS
PAUSE WITH ENT
********************
3. Error VOLTAGE LOSS
This message is shown (as soon as the voltage is back again) if
there is a voltage loss during a running program.
The apparatus resumes the program at the point where it should
have been according to the programmed cycle.
Depending on the duration of the voltage loss, the device also
automatically changes to the „right“ bottle.
