Input contacts (photocoupled)

The connections of the inputs listed below refer to the 18-pole terminal board J5, with numbering starting from
pin 1 from the left. The base of the terminal board also bears the text of the corresponding inputs.
- I 1: Pins 16 and 17
- I 2: Pins 15 and 16
- I 3: Pins 13 and 14
- I 4: Pins 12 and 13
The inputs can be activated in DC or AC (50-60 Hz). The following table shows the electrical specifications of
the inputs: Table 7.
Minimum activation voltage [V]
Maximum deactivation voltage [V]
Maximum admissible voltage [V]
Current absorption at 12V [mA]
Max. admissible cable section [mm²]
N.B. Inputs can be controlled with both polarities (positive or negative with respective return to earth)

With reference to the example in Figure 10 and
using the default settings (O1 = 2: contact NO;
O2 = 2; contact NO) the following is obtained:

L1 lights up when the pump is blocked
(e.g. "BL": water failure block).

L2 lights up when the pump is running
("GO").
