d) Digital inputs DI1 to DI4
Controller has 4 digital inputs on which a tank bottom, flow, R.I.C (Remote Input Control), or orther
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 other sensor on DI1:
 Preferably use a two-strand cable.
 Connect one sensor strand to the DI1 sw (20) connection.
 Connect the other sensor strand to the DI1 - (21) connection.
 Tighten the cable gland to seal.
