4.3.7 Measuring input connections

Tab. 2: The supported sensors are defined as follows (pH):
pH value (input PI1 or PI2)
(*): The customer's scale can be defined between -1 ... 15 pH.
Tab. 3: The supported sensors are defined as follows (ORP):
ORP value (input PI1 or PI2)
(*): The customer's scale can be defined between -1000 ... 1000 mV.

3. Guide the cable through a suitable cable gland.
4. Connect the phase to L1 and the neutral conductor to the N
of the main terminal X1.
5. Use an M4 eyelet clamp to connect the earth to the PL1 bolt.
6. Tighten the cable gland to make a seal.
The device has 10 inputs:
2 potentiometric inputs PI1 & PI2 for pH and ORP sensors,
n
2 inputs AI1 & AI2, 4 ... 20 mA, insulated for temperature,
n
chlorine or bromine measurement,
2 inputs AI3 & AI4, 4 ... 20 mA, uninsulated for temperature,
n
chlorine or bromine measurement,
4 digital inputs DI1 ... DI4 for sensors.
