Normally open
Pulse contact
You decide whether the alarm relay should be a Normally Open (NO) or Normally Closed (NC) contact. At
works it is set to NO, but via the basic settings you can change it to NC. In that case the relay is kept closed
actively, so in case of power failure it opens, thus issuing an alarm.
You can also decide whether the relay should switch permanently during an alarm or whether it should only
give a pulse. This allows independent acknowledgement of the alarm to shut off horns, for example. It also
allows registration of subsequent alarms. At works the configuration is permanent contact.

Error messages
Error message
Cause
Action
Slope error
The slope determined by calibration
was higher than 200% or lower than
20 %.
Please check the sensor connection
and cable, the flow, and the
temperature sensor and settings.
Then repeat the calibration.
If the error message remains, the
sensor has to be cleaned, regenerated,
or replaced.
Error input 1
The measuring sensor gives no
signal.
Please check the connections, the
cable and the sensor for signs of
damage.
Error input 2
The temperature sensor gives no
signal.
Please check the connections, the
cable and the sensor for signs of
damage. This message also appears if
automatic temperature compensation
was selected although no temperature
sensor was used.
Limit 1 / 2
The measured value exceeded
limit 1 (or dropped below limit 2,
respectively).
Please check the dosing and readjust
the control parameters, if necessary.
Dosage check 1 / 2
Controller 1 (or 2, resp.) gives out a
100% output for more than the
defined period of time.
Please check the dosing, especially the
feeding tubes and connections.
Caution! Carefully check for leaking
chemicals!
Ext. controller stop
The digital input has been short-
circuited (in the „contact“ mode).
This only indicates the external
controller stop. If, you have connected
the flow monitor, this message appears
due to the „lack of water“ alarm.
Cleaning in progress
The automatic sensor cleaning has
started less than five minutes ago.
The message will disappear
automatically five minutes after the
start of the cleaning process.
While it´s displayed, calibration is not
possible.
