The mains terminals may still have dangerous voltage when the motor is stopped and for a few minutes
after disconnecting from the power mains.
The line voltage may change when the electropump is started. The line voltage may undergo variations
depending on other devices connected to it and on the quality of the line.
2.3 Electrical connections for auxiliary inputs and outputs
The pump has a connector for configurable user inputs and outputs.
The output is made from a relay (clean contact), with the following electrical characteristics.
Type of contact
Max. bearable voltage [V]
Max. bearable current [A]
Max. bearable power
The functions that can be activated on the output contact are described in paragraph 6.2.6.2.
The following inputs are available (see also par. 6.2.6.1):
1. A digital input, with clean contact (maximum voltage 5Vdc, maximum current 1mA); the closed contact means
"run", the open contact means "stop".
2. An input for an external analog signal, configurable as 0-10V or 4-20 mA .
The following figure shows the relationship between the analog signal on input and the setpointSP to be activated.
See the following parts of this manual for further information on operation.
