Overview
The pump controller can operate on a single phase or 3-phase network. It provides 3 functions in one unit:
●
Checking current,
●
Checking phase presence (in 3-phase mode),
●
Checking phase sequence (in 3-phase mode).
It has two operating modes whose purposes is to control a pump based on two external signal inputs (Y1 Y2).
These two signals are controlled by volt-free contacts.
Faults are signalled via LEDs, distinguishing the origin of the fault.
Operating principle
Selecting the operating mode
A rotary switch on the front is used to select:
- single control mode,
- dual control mode,
- single-phase or 3-phase network.
The position of this selector switch is only taken into account when the unit is powered up.
If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the mode selected on
energisation prior to the change of position.
The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.
HPC - Single control mode This mode is for controlling a pump based on one external signal (Y1).
The relay output is closed when the signal is present at Y1 (contact closed).

After a fault the relay remains open (even if the current returns to normal) and the module can be
reclosed in two different ways:
- By a reset: cutting of power supply,
- Or by a reset through pressing an external contact (pushbutton for example) entering the
second control input (Y2).

The output relay closes when both input signals are present (Y1 and Y2 closed).
It will open as soon as either of these two signals is absent.
If the controller is configured in single phase, it monitors the current drawn by the pump.
If the controller is configured in 3-phase, it monitors current, phase sequence and phase failure.
If a phase fault is detected, the output relay opens immediately.
On energisation, the output relay cannot be closed if there is a phase fault or phase failure.

The under and overcurrent values are set by two independent potentiometers graduated from 1
to 10 A.
In case of a control error (low threshold higher than high threshold), the output relay opens and all
the
LEDs flash to signal the error.
I
If a current fault occurs (under or overcurrent) the relay opens if the fault persists
beyond the preset threshold delay. When the current returns to a correct value, the output relay
remains open. It can only be closed by a reset: either by de-energisation or by closing on
external contact Y2 (in single control mode)
An inhibit delay (Ti) on energisation allows current peaks due to start-up of the motor to be
disregarded.
