Electrical Connections For Auxiliary Inputs And Outputs - DAB E.SWIM Instructions Pour L'installation Et La Maintenance

2.5 Electrical connections for auxiliary inputs and outputs

The pump has a connector for configurable user inputs and outputs.
The following figure shows the connector contacts, while the table below sums up the associated signals:
The auxiliary inputs can be configured for different types of control:
- Digital/analog control
- Control via a digital input.
- Control with multiple digital inputs via E.ADAPT
The operation can be with auxiliary inputs enabled or in override/priority with respect to the programming of the timers.
This allows us to control the pump as a simple slave with respect to the external control panel or as a semi-slave
where the external controls have priority over the programming of the pump but do not exclude it completely.
the characteristics of the auxiliary inputs are:

PIN 1: digital input, clean contact (maximum voltage 5Vdc, maximum current 1mA); the contact is configurable
if normally closed or open (see par. 5.7 "INPUT TYPE")
Alternatively, it corresponds to the positive pole A (+) of the RS485 serial port for connecting the E.ADAPT
interface for expanding digital contacts.

PIN 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 speed SP to be
activated.
Alternatively, it corresponds to the negative pole B (-) of the RS485 serial port for connecting the E.ADAPT
interface for expanding digital contacts.

PIN 3: Earth contact for the connection of all inputs.

The inputs are not opto-isolated.
The output is made from a relay (clean contact), with the following electrical characteristics.
