Operating principle
EUS - The operating principle of the EUS control relays is identical to that for the EU control relays.
Two operating mode are available :
- AC / DC voltage control without memory
- AC / DC voltage control with memory
Note : Time delay T1 on crossing the upper and lower thresholds provides protection to transients,
thus preventing spurious triggering of the output relay.

Operating principle
EUSF - The EUSF window threshold relay controls an electrical voltage which acts as its own
power supply (simplified wiring). When the value of the controlled voltage, AC or DC, goes outside
the window, the output relay de-energises at the end of a time delay T1 which can be set on the
front face at between 0.1 and 3s.
It switches back on when the voltage returns within the window and stays between the upper and
lower thresholds displayed by two potentiometers on the front face. Fixed hysteresis ensures
bounce-free relay switching around the threshold.
Note : Time delay T1 on crossing the upper and lower thresholds provides protection to transients,
thus preventing spurious triggering of the output relay.
