w FUNCTIONS

When the supply voltage U is applied, the output relays switch

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 illumi-nated 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 max-
imum value.

Overvoltage monitoring (OVER, OVER+LATCH)

When the measured voltage exceeds the value adjusted at the
MAX-regulator, the set interval of the tripping delay (DELAY) Undervoltage monitoring (UNDER, UNDER+LATCH)
begins (red LED MAX flashes). After the interval has expired (red When the measured voltage falls below the value adjusted at the
LED MAX illuminated), the output relays switch into off-position MIN-regulator, the set interval of the tripping delay (DELAY) begins
(yellow LED not illuminated). The output relays again switch into (red LED MIN flashes). After the interval has expired (red LED MIN
on-position (yellow LED illuminated), when the measured voltage illuminated), the output relays switch into off-position (yellow LED
falls below the value adjusted at the MIN-regulator (red LED MAX not illuminated). The output relays again switch into on-position
not illuminated). If the fault latch is activated (OVER+LATCH) and (yellow LED illuminated), when the measured voltage exceeds the
the measured voltage remains above the MAX-value longer than value adjusted at the MAX-regulator.If the fault latch is activated
the set interval of the tripping delay, the output relays remain in (UNDER+LATCH) and the measured volt-age remains below the
the off-position even if the measured voltage falls below the value MIN-value longer than the set interval of the tripping delay, the
adjusted at the MIN-regulator. After resetting the failure (inter- output relays remain in the off-position even if the measured volt-
rupting and re-applying the supply voltage), the output relays age exceeds the value adjusted at the MAX-regulator. After reset-
switch into on-position and a new measuring cycle begins with the ting the failure (interrupting and re-applying the supply voltage),
set interval of the start-up suppression (START). the output relays switch into on-position and a new measuring
cycle begins with the set interval of the start-up suppression
(START).

If the fault latch is activated (WIN+LATCH) and the measured volt-

age remains below the MIN-value longer than the set interval of
the tripping delay, the output relays remain in the off-position even
if the measured voltage exceeds the value adjusted at the MIN-reg-
ulator. If the measured voltage remains above the MAX-value
longer than the set interval of the tripping delay, the output relays
remain 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 relays
switch into on-position and a new measuring cycle begins with the
set interval of the start-up suppression (START).

Window function (WIN, WIN+LATCH)

The output relays switch 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 relays switch into
off-position (yellow LED not illuminated). The output relays again
switch into on-position (yellow LED illuminated) when the meas-
ured 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 out-
put relays switch into off-position (yellow LED not illuminated).
