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).

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

remains below the MIN-value longer than the set interval of the

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).

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 illuminated steadily.

For all the functions the LEDs MIN and MAX are flashing alternating,

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 MIN-regulator (red LED MAX not illuminated).

If the fault latch is activated (OVER+LATCH) and 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 MIN-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

illuminated). The output relays again switch into on-position (yellow LED

illuminated), when the measured voltage exceeds the value adjusted

at the MAX-regulator. If the fault latch is activated (UNDER+LATCH)

and the measured voltage 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

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).
