Installation and starting instructions
Connection of the sensor on AI2:
 Preferably use a two-strand cable.
 Connect the sensor (+) strand to the AI1 + (7) connection.
 Connect the sensor (-) strand to the AI1 - (8) connection.
 Tighten the cable gland to seal.
c) Analog inputs 4…20mA NOT isolated AI3 & AI4
Controller has two analog inputs 4…20mA NOT isolated on which a temperature, conductivity,
turbuidity, flowrate or volume Isolated sensor can be connected.
The definition of supported sensors is as follows:
0,2…100NTU Customer*
Turbidity • •
(*): The scale of the customer can be
defined between 0 and 2000 (NTU or FNU)
-5…+45°C Customer*
Temperature • •
(*): The scale of the customer can be defined
between -10 and 100 °C
0…5mS/cm 0…10mS/cm 0…20mS/cm 0…50mS/cm 0…100mS/cm 0…200mS/cm Customer*
Conductivity • • • • • • •
(*): The scale of the customer can be defined
between 0 and 2000 (µS/cm, mS/cm)
Customer*
Volume (4…20mA) •
(*): The scale of the customer can be
defined between 0 and 2000 (L, m3)
