illuminated). When the measured current falls below the value adjus-
ted 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 error memory is activated (WIN+LATCH) and the measured
current 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 current exceeds the value adjusted at the MIN-
regulator. If the measured current 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 current 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).
