6.2.6 External Control

The machine can be controlled by an external control unit or by a PC.
To use this mode, see also paragraphs 5.1.2 and 5.4.
This function is set by means of this sub-menu, which considers separate items for inputs and outputs.
This function is disabled and not configured when the system leaves the factory.
The electrical characteristics of the inputs and outputs are given in paragraph 2.3.

6.2.6.1 Configuration of the Inputs

The inputs are configured from this menu page.
From this item, you first set the general enabling of "EXT External Control" mode.
The inputs include:
‐
a digital input for the START/STOP control;
‐ an analog input, through which the setpoint to be activated is communicated.
The analog input can be selected "in volgage 0-10 V" or "in current 4-20mA".
The setpoint to be activated can be chosen for regulation by Flow or regulation by Speed % (see paragraph 5.1.1.)

6.2.6.2 Configuration of the Outputs

A relay output (clean contact), normally open, is available.
It can be configured to signal:
the running status ("RUN")  When the pump is running the contact closes, and it remains open when the
‐
pump is stopped.
the system block status ("FAULT")  In the case of blocking errors the contact opens, whereas it remains
‐
closed when faults are absent.
The outputs are configured from this menu page.

6.2.7 Priming

Each time the pump starts, the system performs the priming procedure (if enabled).
Priming consists of two phases:
