The alarms are output via relay contacts and the red LED. The number
of up to four alarms is stipulated in the application.
Each alarm can be assigned the following functions:
 Limit value = Min  All values can be selected individually
(Cl

, pH, mV, Cl-N, conductivity)
 Limit value = Max  All values can be selected individually
(Cl

, pH, mV, Cl-N, conductivity)

 Error
The type of alarm can be selected in the "Inputs/Outputs" menu in the
displays "Alarm ... functions" (display 1.7.1 and 1.7.2). There are three
types of alarm.
With all alarm types the response can be influenced by entering a delay
(td) (refer to the diagrams in this section).
The LED lights up in the event of an alarm and goes out automatically
when the alarm conditions are eliminated. The same applies for the
contact.
