Installation and starting instructions
d) Digital inputs DI1 to DI5
Controller has 5 digital inputs on which a tank bottom, flow, R.I.C (Remote Input Control), or another
sensor can be connected.
The definition of supported sensors is as follows:
0…20l/min 0…50l/min 0…200l/min 0…10m3/H Customer*
Flow (impulsions) • • • •
(*): The scale of the customer can be defined between 0 et 2000
(L/min, L/H or m3/H) in 4…20mA or impulse input
Connection of a R.I.C (Remote Input Control), tank bottom or another sensor on DI1:
 Preferably use a two-strand cable.
 Connect one sensor strand to the DI1 sw (17) connection.
 Connect the other sensor strand to the DI1 - (18) connection.
 Tighten the cable gland to seal.
Connection of a flow switch sensor on DI2:
 Remove the protective sheath.
 Strip the wires on 7mm.
 Pass the cable through the cable gland.
 Connect the brown power strand to DI2 + (29).
 Connect the blue power strand to DI2 – (31).
 Connect the black contact strand to DI2 sw (30).
 Tighten the cable gland to seal
