Undervoltage monitoring for 3-phase AC mains with fixed (E1YF) or
variable (E1YU) threshold voltage and fixed hysteresis.
All measuring inputs (L1, L2 and L3) must be connected to phase
voltage.
If single or 2-phase monitoring is required, unused input terminals (L)
must be connected to mains voltage to have proper L-N voltage on the
terminals L1, L2 and L3.
A phase failure can not be detected, if the reverse voltage coming from
the load exceeds the threshold Us.

Undervoltage monitoring
The output relay R switches into on-position (yellow LED illuminated),
when the measuring voltage of all connected phases exeeds the fixed
threshold by more than the fixed hysteresis. When the voltage of one of
the connected phases falls below the fixed threshold, the output relay R
switches into off-position again (yellow LED not illuminated).
Test function (optional)
The test function enables a manually disconnection of the output relay.
