and the requirements and conditions of your equipment. Perhaps the controller has
to be set to slower reactions by choosing a larger proportional range to prevent
overdosing.
Note
Temporary limit exceedance that might happen regularly during
normal operation can be ignored by setting a delay time in the
menu Alarm relay.

Digital input 1
Low water
Level
Ext. controller stop
The digital input was
closed by a connected
sensor or switch
Digital input 1 / low water:
check water flow,
check sensor/connection
Digital input 1 / level:
check container level,
check sensor/connection
The digital input allows connection of a flow sensor or level sensor or an external
switch. According to its intended function, you can assign the digital input one of
three different texts:
„Low water“ if you have connected a flow or water level sensor,
„level“, if you use a level sensor to control the level of a chemical, or „ext. controller
sto
p“, if you use an external switch to activate and deactivate the controller.
Note
Independent of what text you have selected, the controller is
automatically shut down whenever the digital input switches.
Depending on these settings, the suggested remedies differ: If you have selected
„low water“ or „level“, the instrument suggests checking the availability of water or
reagent, and if that is ok, the proper function of the flow or level sensor.
Note
If you have activated a second digital input, this will lead to similar
messages, starting with „digital input 2“.
