Principles
Operating principle
These devices are designed to control an AC or DC electrical signal : voltage using HDUs, current using HDIs.
The threshold and hysteresis can be adjusted separately via two potentiometers on the front face. Before powering up the device, the operating mode
should be selected using two dipswitches located under the device (with/without memory, over/under value). The mode is validated when power is
applied to terminals A1 - A2.
The signal to be monitored is connected between terminals E1, E2, or E3 (depending on the range) and terminal M.
Control of voltage (HDU) or current (HDI) without memory
T
When the value of the controlled signal, AC or DC, reaches the threshold set on the front face, the
output relay opens (failsafe) at the end of time delay T. It closes immediately when the signal goes
below (or above in under value mode) the threshold minus hysteresis (plus hysteresis in under
value mode).

5 Notes
1
The threshold crossing time delay T, which can be adjusted on the front face from 0.1 to 3 sec,
ensures immunity to transients and other inferference, thus preventing spurious triggering of the
output relay.
2
In "under value" mode, the absolute value of the hysteresis cannot be more than the maximum of
3
5 the measurement range.

4
When the threshold is reached, the output relay opens at the end of time-out T and remains in that
position.
To reset the relay, the supply must be cut.
This operating mode enables the detection of over or under values of short duration.
