Functions
When the supply voltage U is applied, the output relay switches into on-
position (yellow LED R and I=0 illuminated) and the set interval of the
start-up suppression (START) begins (green LED U flashes). Changes
of the measured power factor (cosϕ) during this period do not affect the
state of the output relay. After the interval has expired the green LED is
illuminated steadily and the yellow LED I=0 is not illuminated.
Underload monitoring (UNDER, UNDER+LATCH)
When the measured power factor falls below the value adjusted at the
MIN-regulator, the set interval of the tripping delay (DELAY) begins
(red LED MIN flashes). After the interval has expired (red LED MIN
illuminated), the output relay switches into off-position (yellow LED R
not illuminated). The output relay again switches into on-position (yel-
low LED R illuminated), when the measured power factor exceeds the
value adjusted at the MIN-regulator by more than the fixed hysteresis.

Latch active
If the fault latch is activated (UNDER+LATCH) and the measured
power factor remains below the MIN-value longer than the set interval
of the tripping delay, the output relay remains in the off-position even
if the measured power factor exceeds the value adjusted at the MIN-
regulator by more than the fixed hysteresis. After resetting the failure
(interrupting and re-applying the supply voltage), the output relay
switches into on-position and a new measuring cycle begins with the
set interval of the start-up suppression.
Recognition of disconnected consumers
When the current flow between L1i and L1k (yellow LED I=0 illumi-
nated) is interrupted and no fault has been stored the output relay
switches into on-position resp. remains in on-position (yellow LED R
illuminated).
When the current flow is restored, the measuring cycle is restarted
with the set interval of the start-up suppression (START).
