Functions
For all functions the LED‘s Min and Max are ashing alternating (the
relay is fallen off), 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.
The device includes seperately every phase voltage (L-N) and monitors
it according to the selected function (UNDER or WINDOW).
Undervoltage monitoring (UNDER, UNDER+SEQ)
When the measured voltage (one of the phase voltages) falls below the
value adjusted at the Min-regulator, the set interval of the tripping delay
(Delay) begins (red LED Min ashes). After the interval has expired
(red LED Min illuminated), the output relay R switches into off-position
(yellow LED not illuminated). The output relay R switches into onposition again (yellow LED illuminated), when the measured voltage (all
phase voltages) exceeds the value adjusted at the Max-regulator.
Phase sequence monitoring (SEQ)
Phase sequence monitoring is selectable for all functions.
In single phase circuit, the phase sequence monitoring must be
disconnected.
If a change in phase sequence is detected (red LED SEQ illuminated),
the output relay R switches into off-position after the set interval of
tripping delay (Delay) has expired (yellow LED not illuminated).
Neutral wire break
The device monitors every phase (L1, L2 and L3) against the neutral
wire N.
A shift of neutral point occurs by an asymmetrical phase load if the
neutral wire breaks in the power line. If one of the phase voltages
exceeds the value adjusted at the trip point, the set interval of tripping
delay (Delay) begins (red LED Min or Max ashes). After the interval has
expired (red LED Min or Max illuminated), the output relay switches into
off-position (yellow LED not illuminated).
Windowfunction (WIN, WIN+SEQ)
The output relay R switches into on-position (yellow LED illuminated),
when the measured voltage (all phase voltages) exceeds the value
adjusted at the Min-regulator. When the measured voltage (one of the
phase voltages) exceeds the value adjusted at the Max-regulator, the
set interval of tripping delay (Delay) begins (red LED Max ashes).
After the interval has expired (red LED Max illuminated) the output relay
R switches into off-position (yellow LED not illuminated). The output
relay switches into on-position again (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 (one of the
phase voltage) falls below the value adjusted at the Min-regulator, the
set interval of tripping delay (Delay) begins again (red LED Min ashes).
After the interval has expired (red LED Min illuminated), the output relay
R switches into off-positon (yellow LED not illuminated).
