5 Page 1 1. GEERAL The SE-703 is a microprocessor-based earth-leakage monitor for ac power supply systems incorporating earthfault current limitation. Its output relay can operate in the fail-safe or non-fail-safe mode for undervoltage or shunt-trip applications. The SE-703 has one output relay with isolated normally open and normally closed contacts for use in independent control circuits. Additional features include LED trip and power indication, latching trips with front-panel and remote reset, trip memory, test switch, self diagnostics, 0 to 5-V analog output, CT verification with LED indication, digital selector switches, and switch-selectable algorithms for fixed-frequency or variable-frequency applications. Earth-leakage current is sensed by an EFCT-series core-balance, earth-fault current transformer. The trip level of the earth-leakage circuit is digital-switch selectable from 25 to 500 ma. Trip time is digitalswitch selectable from 50 to 500 ms. The SE-703 is AS/ZS 2081:2002 compliant. 2. OPERATIO 2.1 COFIGURATIO-SWITCH SETTIGS See Fig RELAY OPERATIG MODE Switch 1 is used to set the operating mode of the output relay. In the fail-safe mode, the output relay energizes when the earth-leakage circuit is not tripped. In the fail-safe mode, non-volatile memory retains the trip status of the SE-703. If tripped, and the supply voltage is cycled, the SE-703 will remain tripped, with the trip relay de-energized and the TRIP LED on, until reset. In the non-fail-safe mode, the output relay energizes when an earth-leakage trip occurs. In the non-fail-safe mode, trip status is not retained in non-volatile memory FILTER SELECTIO Switch 2 is used to select the filtering algorithm for a fixed-frequency (50/60 Hz) or variable-frequency application. The FIXED FREQUECY setting uses a DFT filter that allows lower trip levels to be used by rejecting harmonics that can cause nuisance tripping. The VARIABLE FREQUECY setting uses a peakdetection algorithm with a wider bandwidth for fault detection in variable-frequency drive applications. 2.2 FROT-PAEL COTROLS EARTH-LEAKAGE TRIP LEVEL The LEVEL (ma) selector switch is used to set the earth-leakage trip level. For earth-leakage detection, the earth-leakage trip level must be substantially below the prospective earth-fault current. To avoid sympathetic tripping, the trip level must be above the charging current of the protected feeder EARTH-LEAKAGE TRIP TIME The SE-703 has a definite-time trip characteristic. The TIME (ms) selector switch is used to set the earthleakage trip time for coordination with upstream and downstream earth-fault devices. Coordination requires the same trip level for all earth-leakage devices in a system and the trip time to progressively increase upstream. The amount of equipment removed from the system will be a minimum if the first earth-leakage device to operate is the one immediately upstream from the fault RESET A trip remains latched until the RESET switch is pressed or the remote-reset terminals (6 and 7) are momentarily connected. In the non-fail-safe relay operating mode, cycling the supply voltage will also reset the SE-703. The reset circuit responds only to a momentary closure so that a jammed or shorted switch will not prevent a trip. The front-panel RESET switch is inoperative when the remote-reset terminals are connected TEST The TEST switch is used to test the earth-leakage circuit, the indication, and the output relay. When the TEST switch is pressed for one second, a test signal is applied to the earth-leakage-detection circuit, the circuit will trip, the TRIP LED will light, and the output relay will operate. 2.3 FROT-PAEL IDICATIO POWER The green LED labeled PWR indicates presence of supply voltage TRIP The red LED labeled TRIP indicates a trip. A solid red LED indicates an earth-leakage trip and a flashing LED indicates a trip initiated by a CT fault. Two fast flashes of the TRIP LED indicate a diagnostic trip. See Section CT VERIFICATIO The green LED labeled CT indicates that an EFCTseries sensor is connected.

7 Page AALOG OUTPUT The non-isolated, 0 to 5-V analog output indicates earthleakage current sensed by the EFCT. The output is 5 V when earth-leakage current is 500 ma. Use a PGA-0500 Analog Percent Current Meter to indicate earth-leakage current. See Figs. 2, 3, and SELF DIAGOSTICS A diagnostic trip is indicated by two fast flashes of the TRIP LED. It can be caused by a problem detected by an incorrect reading from non-volatile memory. Press RESET or cycle supply voltage. If the problem persists, consult Littelfuse Startco. 3. ISTALLATIO OTE: Mounting, terminal-block connections and wiring must conform to applicable local electrical codes. Check all applicable codes prior to installation This earth-leakage monitoring system consists of an SE-703 Earth-Leakage Monitor and an EFCT-series current sensor connected as shown in Figs. 2 and 3. An SE-703 can be surface or DI-rail mounted. See Fig. 1. Panel mounting requires a PMA-55 or PMA-60 Panel-Mount Adapter. See Figs. 7 and 8. A PMA-60 meets the AS/ZS 2081:2002 IP53 requirement. Use terminal 11 (L1) as the line terminal on ac systems or the positive terminal on dc systems. Use terminal 10 (L2/) as the neutral terminal on ac systems or the negative terminal on dc systems. Connect terminal 9 ( ) to ground. Pass the phase conductors through the EFCT window and position them in the centre of the opening for 4-wire and single-phase systems, also pass the neutral conductor through the EFCT window, see Figs. 2 and 3. Do not pass earth conductors through the EFCT window. In applications that require shields or drain wires to pass through the EFCT window, return them through the EFCT window before connecting them to earth. Connect the EFCT current sensor to terminals 4 and 5, connect the shield to terminal 5, and earth terminal 5. See Figs. 4, 5, and 6 for EFCT-series current-sensor dimensional drawings. Remove the connection to terminal 9 for dielectricstrength testing.

Typical Three-Phase Starter Connection. 4. SE-703 COMPATIBILITY The current SE-703 has been enhanced with the addition of non-volatile trip memory for the fail-safe relay operating mode. Prior to hardware revision 04, a mechanical flag was used instead of non-volatile trip memory. The current revision of the SE-703 can directly replace previous revision units. The hardware-revision number is listed on the SE-703 model/serial-number label affixed to the SE-703 enclosure. Both generations of SE-703 are compared in Table 1. The SE-703 was previously available with SE Vac and SE Vac control-voltage options. These have been discontinued. An SE-703-0U universal 120/240-Vac/Vdc unit can directly replace an SE or SE Device state after supply voltage cycled when tripped (earth-fault removed) 9 TABLE 1.

17 Page PERFORMACE TEST Some jurisdictions require periodic earth-fault performance tests. A test-record form is provided for recording the date and the results of the performance tests. The following ground-fault system tests are to be conducted by qualified personnel: a) Evaluate the interconnected system in accordance with the overall equipment manufacturer s detailed instructions. b) Verify proper location of the earth-fault current transformer. Ensure the cables pass through the earth-fault-current-transformer window. This check can be done visually with knowledge of the circuit. The connection of the current-transformer secondary to the SE-703 is not polarity sensitive. c) Verify that the system is correctly earthed and that alternate earth paths do not exist that bypass the current transformer. High-voltage testers and resistance bridges can be used to determine the existence of alternate earth paths. d) Verify proper reaction of the circuit-interrupting device in response to a simulated or controlled earth-fault current. To simulate earth-fault current, use CT-primary current injection. Fig. 10 shows a test circuit using an SE-400 Ground-Fault-Relay Test Unit. The SE-400 has a programmable output of 0.5 to 9.9 A for a duration of 0.1 to 9.9 seconds. Fig. 10 shows the use of resistors that reduce the injected current to 10% of the SE-400 setting. Set the test current to 120% of the SE-703 setting. Inject the test current through the current-transformer window for at least 2.5 seconds. Verify that the circuit under test has reacted properly. Correct any problems and re-test until the proper reaction is verified. e) Record the date and the results of the test on the attached test-record form.
