Datasheet

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.
