Window function (WIN)
The output relay switches into on-position (yellow LED illuminated) when
the measured voltage exceeds the value adjusted at the MIN-regulator.
When the measured voltage exceeds the value adjusted at the MAX-
regulator, the set interval of the tripping delay (DELAY) begins (red LED
MAX flashes). After the interval has expired (red LED MAX illuminated),
the output relay switches into off-position (yellow LED not illuminated).
The output relay again switches into on-position (yellow LED illuminated)
when the measured voltage falls below the value adjusted at the MAX-
regulator (red LED MAX not illuminated). When the measured voltage
falls below the value adjusted at the MIN-regulator, the set interval of the
tripping delay (DELAY) begins again (red LED MIN flashes). After the
interval has expired (red LED MIN illuminated), the output relay switches
into off-position (yellow LED not illuminated).
If the fault latch is activated (bridge Y1-Y2) and the measured voltage
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 voltage exceeds the value adjusted at the MIN-regulator. If
the measured voltage remains above the MAX-value longer than the set
interval of the tripping delay, the output relay remains in the off-position
even if the measured voltage falls below the value adjusted at the MAX-
regulator. 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
(START).

Functions
When the supply voltage U is applied, the output relay switches into
on-position (yellow LED illuminated) and the set interval of the start-up
suppression (START) begins (green LED U flashes). Changes of the
measured voltage during this period do not affect the state of the output
relay. After the interval has expired the green LED is illuminated steadily.
For all the functions the LEDs MIN and MAX are flashing alternating,
when the minimum value for the measured voltage was chosen to be
greater than the maximum value.
Overvoltage monitoring (OVER)
When the measured voltage exceeds the value adjusted at the MAX-
regulator, the set interval of the tripping delay (DELAY) begins (red
LED MAX flashes). After the interval has expired (red LED MAX
illuminated), the output relay switches into off-position (yellow LED not
illuminated). The output relay again switches into on-position (yellow
LED illuminated), when the measured voltage falls below the value
adjusted at the MIN-regulator (red LED MAX not illuminated). If the fault
latch is activated (bridge Y1-Y2) and the measured voltage remains
above the MAX-value longer than the set interval of the tripping delay,
the output relay remains in the off-position even if the measured voltage
falls below the value adjusted at the MIN-regulator. 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 (START).

Undervoltage monitoring (UNDER)
When the measured voltage 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 not illuminated).
The output relay again switches into on-position (yellow LED
illuminated), when the measured voltage exceeds the value adjusted
at the MAX-regulator. If the fault latch is activated (bridge Y1-Y2) and
the measured voltage 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 voltage exceeds the value adjusted at the MAX-
regulator. 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
(START).
