3. Level sensor:
The circuit board has a connection slot for a level sensor, which can be of two types:
a. classic with clean contact (NO or NC) (no power required) to be con-
nected to pin 3 and 4 of the 4-pole connector;
b. optical (or other technology) with Open-Drain or Open-Collector
outlet (requires power) For this condition, the same baTery voltage powering the pump
(24Vdc) is available at the output of terminal 2. Therefore, the terminals to be connected
are 2,3,4 as shown by the following diagram.
The contact can then be Normally Open (NO) or Normally Closed (NC). The selection of
the type of contact is made by means of a jumper located behind the screw terminals (see
next picture)

4. Remote Control Circuit Board:
It is possible to operate the ON/OFF buTon and the 3 diagnostics LEDs by remote up
to a distance of 10 metres by means of a kit. The circuit board must be connected to the
pump with a second remote circuit board according to the following diagram. The con-
nection is carried out by means of a 5-core shielded cable.
