1. GENERAL
The SE-703 is a microprocessor-based earth-leakage
monitor for ac power supply systems incorporating earth-
fault 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 digital-
switch selectable from 50 to 500 ms.
The SE-703 is AS/NZS 2081:2002 compliant.
2. OPERATION
2.1 CONFIGURATION-SWITCH SETTINGS
See Fig. 1.
2.1.1 RELAY OPERATING 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.
2.1.2 FILTER SELECTION
Switch 2 is used to select the filtering algorithm for a
fixed-frequency (50/60 Hz) or variable-frequency
application. The FIXED FREQUENCY setting uses a
DFT filter that allows lower trip levels to be used by
rejecting harmonics that can cause nuisance tripping.
The VARIABLE FREQUENCY setting uses a peak-
detection algorithm with a wider bandwidth for fault
detection in variable-frequency drive applications.
2.2 FRONT-PANEL CONTROLS
2.2.1 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.
2.2.2 EARTH-LEAKAGE TRIP TIME
The SE-703 has a definite-time trip characteristic. The
TIME (ms) selector switch is used to set the earth-
leakage 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.
2.2.3 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.
2.2.4 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 FRONT-PANEL INDICATION
2.3.1 POWER
The green LED labeled PWR indicates presence of
supply voltage.
2.3.2 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 2.5.
2.3.3 CT VERIFICATION
The green LED labeled CT indicates that an EFCT-
series sensor is connected.

2.4 ANALOG OUTPUT
The non-isolated, 0 to 5-V analog output indicates earth-
leakage current sensed by the EFCT. The output is 5 V
when earth-leakage current is 500 mA.
2.5 SELF DIAGNOSTICS
A diagnostic trip is indicated by two fast flashes of the
TRIP LED. It can be caused by a problem detected by the
watchdog timer, or by an incorrect reading from non-
volatile memory. Press RESET or cycle supply voltage.
If the problem persists, consult Startco.
3. INSTALLATION
This earth-leakage monitoring system consists of an
SE-703 Earth-Leakage Monitor and an EFCT-series
current sensor connected as shown in Fig. 2.
An SE-703 can be surface or DIN-rail mounted. See
Fig. 1. Panel mounting requires a PMA-55 or PMA-60
Panel-Mount Adapter. See Figs. 6 and 7. A PMA-60
meets the AS/NZS 2081:2002 IP53 requirement.
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). 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. 3, 4, and 5 for
EFCT-series current-sensor dimensional drawings.
Remove the connection to terminal 9 for dielectric-
strength testing.

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-703-01
120-Vac and SE-703-02 240-Vac control-voltage options.
These have been discontinued. An SE-703-0U universal
120/240-Vac/Vdc unit can directly replace an SE-703-01
or SE-703-02.

7. WARRANTY
The SE-703 Earth-Fault Monitor is warranted to be
free from defects in material and workmanship for a
period of five years from the date of purchase.
Startco Engineering Ltd. will (at Startco’s option)
repair, replace, or refund the original purchase price of
an SE-703 that is determined by Startco to be defective if
it is returned to the Startco factory, freight prepaid,
within the warranty period. This warranty does not
apply to repairs required as a result of misuse,
negligence, an accident, improper installation, tampering,
or insufficient care. Startco Engineering Ltd. does not
warrant products repaired or modified by non-Startco
Engineering Ltd. personnel.

8. PERFORMANCE 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. 8 shows a test
circuit using a Startco 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. 8 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.
NOTE: Do not inject test current directly into CT-input
terminals 4 and 5.
