6 Micrologic E control units protect power circuits. They also offer measurements, display, communication and current maximeters. Version 6 provides earth-fault protection. "Ammeter" measurements (Micrologic A) "Energy meter" measurements (Micrologic E) True RMS current (I1, I2, I3, In, Ig): Micrologic A / Micrologic E current demand voltages: phase to phase, phase to neutral, average (1) and unbalanced (1) E instantaneous power: P, Q, S power factor: PF power demand: P demand 11 energy: Ep, Eq (1), Es (1). Accuracy of active energy Ep is 2 % (including the sensors). The range of 10 measurement is the same as current with Micrologic A, depending of an external power supply module (24 V DC). Communication option In conjunction with the COM communication option, the control unit transmits the 12 following: settings all "ammeter" and "energy" measurements enable connection to FDM121 (E only) tripping causes maximeter / minimeter readings. Protection Protection thresholds and delays are set using the adjustment dials. Overload protection 13 True rms long-time protection. Thermal memory: thermal image before and after tripping. Setting accuracy may be enhanced by limiting the setting range using a different longtime 14 rating plug. Overload protection can be cancelled using a specific LT rating plug "Off". Short-circuit protection Short-time (rms) and instantaneous protection. Selection of I 2 t type (ON or OFF) for short-time delay. Earth-fault protection 1 Source ground return earth fault protection. 4 2 Selection of I 2 t type (ON or OFF) for delay. Neutral protection 6 On three-pole circuit breakers, neutral protection is not possible. On four-pole circuit breakers, neutral protection may be set using a three-position switch: neutral unprotected (4P 3d), neutral protection at 0.5Ir (4P 3d+ N/2), neutral 5 7 protection at Ir (4P 4d). Zone selective interlocking (ZSI) 9 A ZSI terminal block may be used to interconnect a number of control units to provide total discrimination for short-time and earth-fault protection, without a delay before 8 3 tripping. Overload alarm A yellow alarm LED goes on when the current exceeds the long-time trip threshold. M2C programmable contacts The M2C (two contacts) programmable contacts may be used to signal envents (Ir, Isd, Alarm Ir, Alarm Ig, Ig). They can be programmed using the keypad on the Micrologic E control unit or remotely using the COM option (BCM ULP). 1 overload alarm (LED) at Ir Fault indications 2 long-time rating plug screw LEDs indicate the type of fault: test connector overload (long-time protection Ir) long-time threshold and tripping delay short-circuit (short-time Isd or instantaneous li protection) short-time pick-up earth fault (Ig) 6 short-time tripping delay internal fault (Ap). 7 instantaneous pick-up 8 earth-fault pickup and tripping delay Trip history (E only) 9 earth-fault test button The trip history displays the list of the last 10 trips. For each trip, the following 10 indicator of tripping cause indications are recorded and displayed: 11 lamp test, reset and battery test the tripping cause: Ir, Isd, li, Ig or Auto-protection (Ap) trips 12 digital display the date and time of the trip (requires communication option). A E 13 three-phase bargraph and ammeter Battery power 14 navigation button to view menu contents The fault indication LEDs remain on until the test/reset button is pressed. Under 15 navigation button to change menu normal operating conditions, the battery supplying the LEDs has a service life of 16 navigation button "quick View" approximately 10 years. Test A mini test kit or a portable test kit may be connected to the test connector on the front (1) Display on FDM121 only. Note: Micrologic E control units come with a transparent leadseal cover as standard. to check circuit-breaker operation. For Micrologic 6.0 E control units, the operation of earth-fault or earth-leakage protection can be checked by pressing the test button located above the test connector. DB126649

ETV only (1) The thermal memory continuously accounts for the amount of heat in the cables, both before and after tripping, whatever the value of the current(presence of an overload or not).the thermal memory optimises the long-time protection function of the circuit breaker by taking into account the temperature rise in the cables.the thermal memory assumes a cable cooling time of approximately 20 minutes. (2) Refer to page D-5 for more details on ZSI. Note: ETV trip units come with a transparent leadseal cover as standard Voltage meter measurements In addition to the ammeter measurements of ETA ETV trip units measure and display: Current demand Voltages: phase to phase, phase to neutral, average and unbalanced The range of measurement is the same as current with ETA, depending of an external power supply module. Protection Protection thresholds and delays are set using the adjustment dials. Overload protection True rms long-time protection. Protects cables (phase and neutral) against overloads Thermal memory (1) : thermal image before and after tripping. Short-time protection The short-time protection function protects the distribution system against impedant short-circuits The short-time tripping delay can be used to ensure discrimination with downstream circuit breaker The I 2 t ON and I 2 t OFF options enhance discrimination with a downstream protection devices Use of I 2 t curves with short-time protection: I 2 t OFF selected: the protection function implements a constant time curve I 2 t ON selected: the protection function implements an I 2 t inverse-time curve up to 10 lr. Above 10 lr, the time curve is constant Earth-fault protection on ETV6G trip system Residual or source ground return earth fault protection. Selection of I 2 t type (ON or OFF) for delay. A ground fault in the protection conductors can provoke local temperature rise at the site of the fault or in the conductors. The purpose of the ground-fault protection function is to eliminate this type of fault. Type Residual Description The function determines the zero-phase sequence current, i.e. the vectorial sum of the phase and neutral currents It detects faults downstream of the circuit breaker Instantaneous protection The Instantaneous-protection function protects the distribution system against solid short-circuits. Contrary to the short-time protection function, the tripping delay for instantaneous protection is not adjustable. The tripping order is sent to the circuit 20 milliseconds. Neutral protection On three-pole circuit breakers, neutral protection is not possible. On four-pole circuit breakers, neutral protection may be set using a three-position switch: neutral unprotected (4P 3d), neutral protection at 0.5 Ir (4P 3d + N/2), neutral protection at Ir (4P 4d). Zone selective interlocking (ZSI) A ZSI (2) terminal block may be used to interconnect a number of control units to provide total discrimination for short-time and earth-fault protection, without a delay before tripping. Overload alarm A yellow alarm LED goes on when the current exceeds the long-time trip threshold. Fault indications LEDs indicate the type of fault: Overload (long-time protection Ir) Short-circuit (short-time Isd or instantaneous li protection) Earth fault (Ig) Internal fault (Ap) Trip history The trip history displays the list of the last 10 trips. For each trip, the following indications are recorded and displayed: the tripping cause: Ir, Isd, Ii, Ig or Auto-protection (Ap) trips Battery power The fault indicating LEDs are powered by an in-built battery. The fault indication LEDs remain on until the test/reset button is pressed. Test A hand-held test kit may be connected to the test connector on the front to check circuit-breaker operation. For ETV6G trip unit, the operation of earth-fault protection can be checked by pressing the test button located above the test connector.
