Overview
HIL and HIH control relays are designed to control AC or DC currents. They automatically recognise the shape of the DC or AC signal (50 or 60 Hz) and can control up to 10 A in DC. Above this level, a current transformer can be connected.
General principle:
The operating mode is set by the user. A switch is used to select over or undercurrent modes, with or without latching. The switch position, and hence the operating mode, is read by the product on energisation. If the switch is set to a non-conforming position, the product goes into fault mode, the output relay stays open, and the LEDs flash to signal the position error. If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the function 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.
The over or undercurrent threshold value is set by a graduated potentiometer as a percentage of the I scale to be monitored. The hysteresis is set by a graduated potentiometer from 5 to 50% of the preset threshold. The hysteresis value cannot be higher than the extremes of the measurement range.
An adjustable time delay from 1 to 20 s on energisation is used to prevent current peaks or troughs on starting.
HIL-HIH - Under/overcurrent - without latching
In overcurrent mode, if the controlled current exceeds the preset threshold for longer than the time set on the front face (0.1 to 3 s), the output relay opens and LED R is extinguished. During the time delay, this LED flashes. Once the current falls below the threshold value minus the hysteresis, the relay closes instantaneously.
In undercurrent mode, if the controlled current falls below the preset threshold for longer than the time set on the front face (0.1 to 3 s), the output relay opens and LED R is extinguished. During the time delay, this LED flashes. Once the current rises above the threshold value plus the hysteresis, the relay closes instantaneously.

If "with memory" mode has been selected, the relay opens and stays in this position when threshold crossing is detected.
