After the interval has expired For all the functions the LEDs MIN and MAX are flashing alternating, (red LED SEQ illuminated), the output relays switch into off-position when the minimum value for the measured voltage was chosen to be (yellow LED not illuminated). Reverse voltages of a consumer (e.g. greater than the maximum value. If a failure already exists when the a motor which continues to run on two phases only) do not effect the device is activated, the output relays remain in off-position and the LED disconnection but can be monitored by using a proper value for the for the corresponding threshold is illuminated. asymmetry. Under voltage monitoring (UNDER, UNDER+SEQ) When the measured voltage (mean value of phase-to-phase voltages) LED SEQ 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), 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 voltage exceeds the value adjusted at the MAX-regulator. L1 L2 L3 Delay Asymmetry monitoring If the asymmetry of the phase-to-phase voltages exceeds the value set at the ASYM-regulator, the set interval of the tripping delay (DELAY) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM illuminated), the output relays switch into off-position (yellow LED not illuminated). If the neutral wire is connected to the device, the asymmetry of the phase voltages referred to the neutral wire (Y-voltage) is monitored also. In that case both values of the asymmetry are evaluated and if one of the values exceeds the value set at the ASYM-regulator, the set interval of the tripping delay (DELAY) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM Window function (WIN, WIN+SEQ) illuminated), the output relays switch into off-position (yellow LED not The output relays switch into on-position (yellow LED illuminated) when illuminated). the measured voltage (mean value of phase-to-phase voltages) exceeds the value adjusted at the MIN-regulator. When the measured voltage exceeds the value adjusted at the MAX-regulator, the set interval of the LED ASYM 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 Asym. into on-position (yellow LED illuminated) when the measured voltage falls below the value adjusted at the MAX-regulator (red LED MAX not L1 L2 L3 illuminated). When the measured voltage falls below the value adjusted at the MIN-regulator, the set interval of the tripping delay (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). Loss of neutral wire by means of evaluation of asymmetry A break of the neutral wire between power line and machinery is detected as soon as asymmetry between phase-to-phase voltage and neutral wire occurs. If the asymmetry exceeds the value set at the ASYM-regulator, the set interval of the tripping delay (DELAY) begins (red LED ASYM flashes). After the interval has expired (red LED ASYM illuminated), the output relays switch into off-position (yellow LED not illuminated). A break of the neutral wire between our device and the machinery can not be detected. Phase sequence monitoring (SEQ) Phase sequence monitoring is selectable for all functions. If a change in phase sequence is detected (red LED SEQ illuminated), the output relays switch into off-position immediately (yellow LED not illuminated). LED SEQ L1 L2 L3 www.tele-online.com
