For all functions the LED's MIN and MAX areflashing alternating, 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 off-position and the LED forthe corresponding threshold is illuminated. UNDER, UNDER+LATCH - undervoltagemonitoring, undervoltage monitoring withfault latch OVER, OVER+LATCH - overvoltagemonitoring, overvoltage monitoring with fault latch The output relay R switchs into on-position (yellowLED illuminated) when the measured voltage of all the phases exceeds the value adjusted at the MIN-regulator. When the measured voltage of one of the phases exceeds the value adjusted at the MAX-regulator, the set interval of the tripping delay(Delay) begins (red LED MAX flashes). After theinterval has expired (red LED MAX illuminated), theoutput 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 of all the phases falls below the value adjusted at the MAX-regulator (red LED MAX not illuminated). When the measured voltage of one of the phases falls below the value adjusted at the MIN-regulator, the set intervalof the tripping delay (Delay) begins again (red LEDMIN flashes). After the interval has expired (redLED MIN illuminated), the output relay R switchesinto off-position (yellow LED not illuminated).If the fault latch is activated (WIN+LATCH)and the measured voltage of one of the phases remains below the MIN-value longer than the set interval of the tripping delay, the output relay Rremains in the off-position even if the measuredvoltage of all the phases exceeds the value adjusted at the MIN-regulator. If the measured voltage of one of the phases remains above the MAX-value longer than the set interval of thetripping delay, the output relay R remains in theoff-position even if the measured voltage of all the phases falls below the value adjusted at the MAX- regulator. After resetting the failure (interrupting and re-applying the supply voltage), the output relay R switches into on-position and a newmeasuring cycle begins with the set interval ofthe start-up suppression (START). When the measured voltage of one of the phasesfalls 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), the output relay R switches into off-position (yellow LED notilluminated). The output relay R again switchs intoon-position (yellow LED illuminated), when themeasured voltage of all the phases exceeds thevalue adjusted at the MAX-regulator. If the fault latch is activated (UNDER+LATCH) and the measured voltage of one of the phases remains below the MIN-value longer than the set interval of the tripping delay, the output relay Rremains in the off-position even if the measuredvoltage of all the phases exceeds the value adjusted at the MAX-regulator. After resettingthe failure (interrupting and re-applying the supplyvoltage), the output relay R switches into on-positionand a new measuring cycle begins with the set interval of the start-up suppression (START). When the measured voltage of one of the phasesexceeds the value adjusted at the MAX-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 relayR switches into off-position (yellow LED notilluminated). The output relay R again switchs intoon-position (yellow LED illuminated), when the measured voltage of all the phases 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 of one of the phases remains above the MAX-value longer than the set interval of the tripping delay, the output relay Rremains in the off-position even if the measuredvoltage of all the phases falls below the valueadjusted at the MIN-regulator. After resettingthe failure (interrupting and re-applying the supply voltage), the output relay R switchs into on-position and a new measuring cycle begins with the set interval of the start-up suppression (START). - output relay R WIN, WIN+LATCH - voltage monitoringin windowfunction between MIN and MAXvalues, voltage monitoring in windowfunction between MIN and MAX values with fault latch - supply voltage; U Dzia³ Marketingu Tel./Fax +48 68 47 90 830 • Wsparcie Techniczne Tel. +48 68 47 90 820 www.relpol.com.pl
