Operating principle
AC/DC control without memory
When the value of the controlled current, either AC or DC, reaches the threshold displayed on the
front face, the output relay changes state at the end of time delay T1.
It returns instantly to the initial state when the current drops below the hysteresis threshold, or when
the power supply is disconnected.
AC/DC control with memory
The output relay changes state at the end of time delay T1 and remains latched in this position. To
reset the memory function the auxiliary supply must be disconnected.
Over-current function (UPPER)
The time delay on energisation T2 prevents current peaks due to motor starting.
The delay on upward crossing of threshold T1 provides immunity to transients and other
interference, thereby preventing spurious triggering of the output relay.
Under-current function (UNDER)
The time delay on energisation T2 prevents the occurrence of current troughs. The delay on
downward crossing of threshold T1 provides immunity to random dips, thereby preventing spurious
triggering of the output relay.
Note : In underload function, the absolute value of the hysteresis cannot be greater than the
measurement range maximum.
