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 (DE-
LAY) begins (red LED ASYM flashes). After the interval has expired
(red LED ASYM illuminated), the output relay switches into off-posi-
tion (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 relay switches into off-position (yellow LED not illuminated).
If the asymmetry of the phase-to-phase voltages exceeds the value
set at the ASYM-regulator, the set interval of the tripping delay (DE-
LAY) begins (red LED ASYM flashes). After the interval has expired
(red LED ASYM illuminated), the output relay switches into off-posi-
tion (yellow LED not illuminated).

the output relay switches into off-position (yellow LED not illuminated).

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 relay
remains 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 relay
switches into off-position (yellow LED not illuminated). The output re-
lay again switches into on-position (yellow LED illuminated), when the
measured voltage exceeds the value adjusted at the MAX-regulator.
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 relay
switches into off-position (yellow LED not illuminated). The output re-
lay again switches into on-position (yellow LED illuminated), when the
measured voltage exceeds the value adjusted at the MAX-regulator.
Loss of neutral wire by means of evaluation of asymmetry
A break of the neutral wire between power line and machinery is de-
tected 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 relay switches into off-position (yellow
LED not illuminated). A break of the neutral wire between our device
and the machinery can not be detected.

Phase sequence monitoring (SEQ)
Phase sequence monitoring is selectable for all functions.
If a change in phase sequence is detected (red LED SEQ illumi-
nated), the output relay switches into off-position immediately (yellow
LED not illuminated).

Window function (WIN, WIN+SEQ)
The output relay switches 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
relay switches into off-position (yellow LED not illuminated). The
output relay again switches into on-position (yellow LED illuminated)

voltage falls below the value adjusted at the MIN-regulator, the set

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 relay switches 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 moni-
tored by using a proper value for the asymmetry.
