Delay
For all the functions the LEDs MIN and MAX are ashing alter-
nating, 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
R remains in o-position and the LED for the corresponding
threshold is illuminated.
Undervoltage monitoring (U)
When one of the 3 measured voltages (phase-to-phase) falls
below the adjusted threshold U
Min
, the set interval of the
tripping delay (DELAY) begins. After the interval has expired,
the output relay R switches into o-position. The output relay
R switches into on-position again after all of the 3 measured
voltages exceed the adjusted threshold U
Max
.
Window function (W)
When one of the 3 measured voltages (phase-to-phase) falls
below the adjusted threshold U
Min
, the set interval of the
tripping delay (DELAY) begins. After the interval has expired,
the output relay R switches into o-position. The output relay
R switches into on-position again after all of the 3 measured
voltages exceed the adjusted threshold U
Min
. When one of the
3 measured voltages (phase-to-phase) exceeds the adjusted
threshold U
Max
, the set interval of the tripping delay (DELAY)
begins. After the interval has expired, the output relay R swit-
ches into o-position. The output relay R switches into on-posi-
tion again after all of the 3 measured voltages fall below the
adjusted threshold U
Max
.
Phase sequence monitoring
Phase sequence monitoring is selectable for all functions.
If a change in phase sequence is detected, the output relay R
switches into o-position immediately.
Phase failure monitoring
If one of the 3 phases fails, the set interval of the tripping delay
(DELAY) begins. After the interval has expired, the output relay
R switches into o-position.
