When the supply voltage U is applied, the outputrelay R switches into on-position (yellow LED illuminated) and the set interval of the start-upsuppression (START) begins (green LED U flashes).Changes of the measured voltage during thisperiod do not affect the state of the output relay R. After the interval has expired the green LEDis illuminated steadily. For all the functionsthe LEDs MIN and MAX are flashing alternating,when the minimum value for the measured voltagewas chosen to be greater than the maximum value. UNDER, UNDER+LATCH - undervoltagemonitoring, undervoltage monitoring withfault latch When the measured voltage exceeds the valueadjusted at the MAX-regulator, the set intervalof the tripping delay (Delay) begins (red LED MAX flashes). After the interval has expired (red LEDMAX illuminated), the output relay R switchesinto off-position (yellow LED not illuminated).The output relay R again switchs 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 themeasured voltage falls below the value adjustedat 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 relay R switches intooff-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 trippingdelay, the output relay R remains in the off-positioneven if the measured voltage exceeds the valueadjusted at the MIN-regulator. If the measuredvoltage remains above the MAX-value longer than the set interval of the tripping delay, the outputrelay R remains in the off-position even if themeasured voltage falls below the value adjustedat the MAX-regulator. After resetting the failure(interrupting and re-applying the supply voltage),the output relay R switches into on-position anda new measuring cycle begins with the set interval of the start-up suppression (START). OVER, OVER+LATCH - overvoltagemonitoring, overvoltage monitoring with fault latch When the measured voltage falls below the valueadjusted at the MIN-regulator, the set intervalof the tripping delay (Delay) begins (red LED MINflashes). After the interval has expired (red LEDMIN illuminated), the output relay R switches into off-position (yellow LED not illuminated).The output relay R again switchs 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 relay R remains in the off-positioneven if the measured voltage exceeds the valueadjusted at the MAX-regulator.
