F&F CP-721-FPV User Manual

- 2 -
The CP-721-FPV relay continuously monitors the voltage in the
mains supply, the measured voltage value is indicated on the
display on the front of the device. If the voltage is detected to
exceed the preset level "Uon", the overvoltage time countdown
starts. If the voltage is exceeded for a time longer than the pre-
set "Uon" value, the built-in relay will switch on. Activation of
the relay is signalled by lighting up the yellow LED located below
the display.
The condition for switching off the relay is that the mains vol-
tage drops below the value ("Uon" – hys), while this voltage
must remain below the preset level for the time set in the "tof"
parameter.
