1. AC/DC voltage control without latching:
The output relay is energized when the voltage (AC peak voltage)
exceeds the selected threshold. It de-energizes when the voltage
falls below the hysteresis setting (5 to 50%) or when supply breaks.
The hysteresis is controlled by a potentiometer and its selection does
not change the chosen threshold.
2. AC/DC voltage control with latching:
The output relay is energized when the voltage reaches the selected
threshold and stays latched in this position. The contact between ter-
minal B1 and M (or 8 or 9) should be opened or the input power of
the device interrupted to reset.

The voltage threshold SR Relay controls a voltage supply which
is its own supply. The output relay is energized when the supply
(effective for AC) exceeds the selected threshold. It de-energizes
when the controlled supply falls below (5 to 20% Hysteresis) of
the supply voltage or when the input power breaks. Hysteresis
is controlled by a potentiometer and its selection does not
change the chosen threshold. Pulses or drops of 100ms or
less are ignored.
