Functions
Output relay On (NO closed) when all OK: positive logic.

Functions
= Output contact
(11-14, 21-24 for 70.42 only)
OV = Overvoltage
OVm = Overvoltage with memory
UV = Undervoltage
UVm = Undervoltage with memory
W = Window mode (OV + UV)
Wm = Window mode (OV + UV)
with memory
H = Hysteresis
If the voltage moves out of limits, following
delay T the output relay turns Off.
When the voltage is again within limits
(± the Switch-on hysteresis H):
– if set in the “without memory” position, the
output relay “recovers”, i.e. it turns On (after
the Switch-on lock-out time) without any
memory of the previous event.
– if set in the “with memory” position (70.11,
70.42 and 70.31 only), the output relay
remains open. To reset, it is necessary to
switch the supply Off and then On again,
or to rotate the selector first to an adjacent
position and then to the original position.
