When the supply voltage U is applied, the output relays switch into When the measured current exceeds the value adjusted at the MAX- on-position (yellow LED illuminated) and the set interval of the start-up regulator, the set interval of the tripping delay (DELAY) begins (red LED suppression (START) begins (green LED U flashes). Changes of the MAX flashes). After the interval has expired (red LED MAX illuminated), measured current during this period do not affect the state of the output the output relays switch into off-position (yellow LED not illuminated). relay. After the interval has expired the green LED is illuminated steadily. The output relays again switch into on-position (yellow LED illuminated) For all the functions the LEDs MIN and MAX are flashing alternating, when the measured current falls below the value adjusted at the MAX- when the minimum value for the measured current was chosen to be regulator (red LED MAX not illuminated). When the measured current greater than the maximum value. 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 Overcurrent monitoring (OVER, OVER+LATCH) interval has expired (red LED MIN illuminated), the output relays switch When the measured current exceeds the value adjusted at the MAX- into off-position (yellow LED not illuminated). 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 measured current 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 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 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 with the set interval of the start-up suppression (START). If the fault latch 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 LATCH 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). Undercurrent monitoring (UNDER, UNDER+LATCH) When the measured current falls below the value adjusted at the MIN- regulator, the set interval of the tripping delay (DELAY) begins (red LED MIN flashes). After the interval has expired (red LED MIN illuminated), LATCH 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 current exceeds the value adjusted at the MAX- regulator. If the fault latch is activated (UNDER+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 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).
