Datasheet

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).
This mode is for controlling a pump based on two external signals (Y1 and 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.
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.
