After the interval the start-up surpression the output relay switches
into on-position the current flow restored, the measured power factor
remains above the set threshold and his hysteresis and failure is
stored. After the interval has expired (red LED MIN
illuminated), the output relay switches into off-position (yellow LED R
not illuminated).G2CU400V10AL10
www. After the interval has expired the green
LED illuminated steadily. After the interval has expired (red LED MIN
illuminated), the output relay switches into off-position (yellow LED not
illuminated).
After resetting the failure (interrupting and re-applying the supply
voltage), the output relay switches into on-position and new measuring
cycle begins with the set interval the start-up suppression.
When the current flow restored, the measuring cycle restarted with
the set interval the start-up supression.
Functions
When the supply voltage applied, the output relay switches into
on-position (yellow LED and the set interval the start-up suppression
(START) begins (green LED flashes).com

When the current flow between and interrupted and fault has
been stored, the output acts shown the table. The output relay again switches into on-position (yellow
LED illuminated), when the measured power factor exceeds the value
adjusted the MIN-regulator more than the fixed hysteresis. the current doesn’t flow during
the start-up supression the yellow LED I=0 illuminated. the measured power factor exceeds the value adjusted
at the MIN-regulator more than the fixed hysteresis, the ouput relay
stays off-position.
Changes the measured power factor (cosϕ) during this period not
affect the state the output relay.(START)
