Functions
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. If a failure already exists when the
device is activated, the output relays remain in off-position and the LED
for the corresponding threshold is illuminated.
Under voltage monitoring (UNDER, UNDER+SEQ)
When the measured voltage (mean value of phase-to-phase voltages)
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 relays switch into
off-position (yellow LED not illuminated). The output relays again switch
into on-position (yellow LED illuminated), when the measured voltage
exceeds the value adjusted at the MAX-regulator.
Window function (WIN, WIN+SEQ)
The output relays switch into on-position (yellow LED illuminated) when
the measured voltage (mean value of phase-to-phase voltages) 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 relays switch into
off-position (yellow LED not illuminated). The output relays again switch
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 relays switch into off-position (yellow
LED not illuminated).
Phase sequence monitoring (SEQ)
Phase sequence monitoring is selectable for all functions.
If a change in phase sequence is detected (red LED SEQ illuminated),
the output relays switch into off-position immediately (yellow LED not
illuminated).

Phase failure monitoring (SEQ)
If one of the phase voltages fails, the set interval of the tripping delay
(DELAY) begins (red LED SEQ flashes). After the interval has expired
(red LED SEQ illuminated), the output relays switch into off-position
(yellow LED not illuminated). Reverse voltages of a consumer (e.g.
a motor which continues to run on two phases only) do not effect the
disconnection but can be monitored by using a proper value for the
asymmetry.
Asymmetry monitoring
If the asymmetry of the phase-to-phase voltages exceeds the value set
at the ASYM-regulator, the set interval of the tripping delay (DELAY)
begins (red LED ASYM flashes). After the interval has expired (red LED
ASYM illuminated), the output relays switch into off-position (yellow
LED not illuminated). If the neutral wire is connected to the device,
the asymmetry of the phase voltages referred to the neutral wire
(Y-voltage) is monitored also. In that case both values of the asymmetry
are evaluated and if one of the values exceeds the value set at the
ASYM-regulator, the set interval of the tripping delay (DELAY) begins
(red LED ASYM flashes). After the interval has expired (red LED ASYM
illuminated), the output relays switch into off-position (yellow LED not
illuminated).
Loss of neutral wire by means of evaluation of asymmetry
A break of the neutral wire between power line and machinery is
detected as soon as asymmetry between phase-to-phase voltage and
neutral wire occurs. If the asymmetry exceeds the value set at the
ASYM-regulator, the set interval of the tripping delay (DELAY) begins
(red LED ASYM flashes). After the interval has expired (red LED ASYM
illuminated), the output relays switch into off-position (yellow LED not
illuminated). A break of the neutral wire between our device and the
machinery can not be detected.
