MONITOR
The red alarm LED L1, L2, L3 > Y will illuminate and the alarm relays
(11-12/14 & 21-22/24, normally de-energized) will change state in
accordance to the diagram below, if the response value "Y" is reached
or passed on either L1, L2 or L3. This event can be delayed through a
potentiometer on the front trim by 0.3 to 5 seconds.
The SUD472 will return to a normal operating mode as soon as the
overvoltage condition is no longer present.

Function2
1. Use as an overvoltage relay V > Y
The red alarm LED L1, L2, L3 < Y will illuminate and the alarm relays
(11-12/14 & 21-22/24, normally energized) will change state in
accordance to the diagram below, if the response value "Y" is reached
or decreased on either L1, L2 or L3. This event can be delayed through
a potentiometer on the front trim by 0.3 to 5 seconds.
The SUD472 will return to a normal operating mode as soon as the
under voltage condition is no longer present.The red alarm LED will
extinguish.
