3UG4625 residual current monitoring relay with 3UL23 transformer 9.3 Functions 9.3 Functions General functionality 3UG4625 residual current monitoring relays are supplied with a rated control supply voltage of 24 to 240 V AC/DC (rms value), 50/60 Hz via terminals A1+ and A2-. 3UG4625 residual current monitoring relays are equipped with a display and are parameterized with three keys. You will find the setting ranges and factory settings of the available parameters in Chapter "Operation (Page 196)".
3UG4625 residual current monitoring relay with 3UL23 transformer 9.3 Functions ● Wide-range supply voltage 3UG4625 residual current monitoring relays can be operated at an input voltage of between 24 and 240 V AC/DC. This not only ensures that devices can be used worldwide, but that temporary supply voltage dips do not cause a failure of the monitoring function, that is, plant stoppage.
3UG4625 residual current monitoring relay with 3UL23 transformer 9.3 Functions Limits of fault current measurement In the event of increasing primary currents, transformer production tolerances, imbalances in the cable routing and current loads in individual cables increasingly cause what appear to be fault currents that are detected by the evaluation units. An increased false tripping may occur if excessively low monitoring limit values have been set at high primary currents.
3UG4625 residual current monitoring relay with 3UL23 transformer 9.3 Functions The monitored current waveforms also have a strong influence on the measuring accuracy. In the case of loads with generalized phase control, deviations from the measuring accuracy can occur when monitoring for high residual current limits. The cause of this is the extreme difference between the monitored rms values and the peak values of the residual current.
3UG4625 residual current monitoring relay with 3UL23 transformer 9.3 Functions Tripping delay If the measured value exceeds the set threshold (I▲) after expiry of the ON-delay time (onDel), the set tripping delay time (I▲Del) starts and the relay symbol flashes. After expiry of this time, the output relay K1 changes the switching state. Exceeding the set warning threshold will cause output relay K2 to switch immediately without taking into account the tripping delay time.

Accessories 14.2 Accessories for 3UG4 monitoring relays 14.2.5.2 Installation specifications Note Please ensure strict adherence to the installation specifications for live cables. WARNING Open-circuit voltage may result in death, serious injury or material damage The current transformer output is a constant current power supply. In accordance with U = R * I, the output voltage increases with an increasing resistance.
Accessories 14.2 Accessories for 3UG4 monitoring relays All live cables must be routed as close to the center of the transformer as possible. Any neutral conductor must be routed through the transformer. Grounded protective conductors must not be routed through the transformer or need to be routed through the transformer in both directions.
Accessories 14.2 Accessories for 3UG4 monitoring relays The internal transformer diameter must be at minimum twice the size of the power cable bundle diameter.
Accessories 14.2 Accessories for 3UG4 monitoring relays Transformer connection Transformer connecting cables must be twisted and not routed in parallel to live cables to protect from emitted interference. Keep the length of the connecting cables to a minimum. The resistance at the transformer connecting cable must not exceed 5 Ω to ensure correct fault current monitoring. This is ensured by the following limits given here as examples. Conductor cross-section [mm²] AWG/[kcmil] Max. cable length [m] 0.
Accessories 14.2 Accessories for 3UG4 monitoring relays 14.2.5.3 Potential for optimization Potential for optimization in the event of extremely high currents, false tripping due to high starting currents or in environments with high EMC interference 1. Extend the ON-delay time to fade out fault currents measured during motor startup. 2. Extend the tripping delay time to prevent false tripping due to EMC interference. 3. Select a residual current transformer with a larger internal diameter.
Accessories 14.2 Accessories for 3UG4 monitoring relays b) A solid shield sleeve, e.g. turned from a normal, low-carbon tool steel must be precisely in contact with the internal ring of the residual current transformer. The wall thickness of the sleeve must be 1 mm at minimum, the length of the sleeve (L) must correspond to the internal diameter of the transformer used. / ① ② ③ 14.2.5.
Accessories 14.2 Accessories for 3UG4 monitoring relays Parallel connections of conductors If several residual current monitoring relays are installed in one network, a conductor routed through several residual current transformers must not be connected to itself downstream of the transformer, as this would effectively represent a parallel connection of the conductor. This fault occurs particularly often with neutral conductors. This fault causes the currents to be distributed across the conductor.
Accessories 14.2 Accessories for 3UG4 monitoring relays Mixing up conductors In a network with several loads there is the risk that active conductors of loads that are to be separately monitored for fault currents can get mixed up. This fault leads to false tripping as the inflowing and outflowing currents are not always exactly the same strength, even if the loads are identical.
Accessories 14.2 Accessories for 3UG4 monitoring relays Routing contrary to the current flow To be able to form the vectorial sum of currents to and from a load correctly, all active conductors must be routed through the residual current transformer from the same direction. Due to the restricted space in a control cabinet it may be easier to route the neutral conductor through the transformer in the opposite direction to the phase conductor.
Accessories 14.2 Accessories for 3UG4 monitoring relays 14.2.5.6 Installing Wall mounting procedure Step Instructions 1/2 Insert the fixing lugs into the designated openings in the unit until they reach the stop. 3 Place the device against the wall surface prepared for establishing a screw connection. 4 Insert the head screws through the corresponding elongated holes in the fixing lugs. 5 Screw the device onto the level surface so that it is secure.

Parameters B Nominal line voltage The nominal voltage is the value of the electrical voltage during normal operation specified by the manufacturer. The nominal voltage is usually stated with a maximum permissible tolerance range. In Europe, the nominal value of the line voltage, the nominal line voltage, is 230 V (line / neutral) or 400 V (line / line).
Parameters Tripping delay time If the measured value overshoots or undershoots the set limit value, the delay time that can be set using the "Tripping delay time" parameter starts. On expiry of this time, the switching contact changes state and a message may be sent via IO-Link.
Parameters Starting the ON-delay time via IO-Link The ON-delay time can also be started through the process image of the outputs (PIQ) by setting the control command "Start ON delay time." This is a simple method of permitting brief load steps during operation if these are predictable. The ON-delay time can be set either locally via the three keys on the device, or via IO-Link.
Parameters (Warning) threshold for undershoot The device monitors a measured value for undershoot. The measured value can be parameterized as a threshold or as a warning threshold (on the 3RR22 and 3UG4583 devices only) for undershoot. The warning threshold defines the switching threshold of the relevant output relay prior to tripping by measured value undershoot.
Parameters Possible indications on the display: ● Current overshoot: I▲ (threshold), I!▲ (warning threshold) ● Voltage overshoot: U▲ (threshold), possibly U!▲ (warning threshold) ● Speed overshoot: rpm▲ (threshold), possibly rpm!▲ (warning threshold) ● Power factor overshoot: φ▲ (threshold), possibly φ!▲ (warning threshold) ● Active current overshoot: Ir▲ (threshold), possibly Ir!▲ (warning threshold) ● Fault current overshoot: I▲(threshold), possibly I!

Parameters Hysteresis Hysteresis is the continuation of an effect within the hysteresis range after its cause has been removed; its purpose is to prevent repeated response in the threshold value range. &RUUHFW UDQJH 1RUPDO UDQJH 7KUHVKROG IRU RYHUVKRRW +\VW 7KUHVKROG IRU XQGHUVKRRW +\VW Figure B-1 0HDVXUHG YDOXH +\VWHUHVLV WKUHVKROG IRU WKH WKUHVKROG IRU RYHUVKRRW +\VWHUHVLV WKUHVKROG IRU WKH WKUHVKROG IRU XQGHUVKRRW Explanation of hysteresis If, after the upper threshold value has been ov
Parameters Fault current monitoring If fault current monitoring has been activated (I >> = yes) and the total current of the load currents at terminals 1L1 / 2T1, 3L2 / 4T2 and 5L3 / 6T3 rises above the permissible threshold (S00: 1.5 A / S0: 4 A), the ON-delay time onDel, the tripping delay time Del, and the restart delay time RsDel are stopped and both the CO contact and the semiconductor output change their switching state immediately (≤ 200 ms).
Parameters Current monitoring principle The monitoring relays monitor an AC load current which flows through the device terminals depending on whether monitoring has been set to check for overshoot or undershoot, or window monitoring.
Parameters Relay switching behavior An output relay responds in accordance with the set switching behavior. Several variations can be distinguished here: ● Closed-circuit principle (NC) If the closed-circuit principle is selected, the output relay picks up when the voltage is applied (contact .1/.4 closed). The output relay drops out in the event of a fault (contact .1/.2 closed).
Parameters Sensor sensitivity The sensor sensitivity is the sensitivity R sens, with which the filling level monitoring relay must respond. The working principle of the filling level monitoring relays is based on resistance measurement of conductive liquids (conductive measurement method). This method can be used with all liquids and substances that have a resistivity < 200 kΩ.
Parameters Stabilization delay An output is only switched to the "correct position" after switching on the supply voltage if all monitored measured values are stable for the duration of the stabilization delay. The monitoring functions are active within the stabilization delay. A threshold overshoot or undershoot in this time does not result in a fault, but instead in restarting of the stabilization delay.
