1. INTRODUCTION
1.1 GENERAL
The SE-701 is a microprocessor-based ground-fault
monitor for resistance-grounded and solidly grounded
systems. It is uniquely suited for use on systems with
significant harmonic content. Its output relay can operate
in the fail-safe or non-fail-safe mode for undervoltage or
shunt-trip applications. The SE-701 has one output relay
with isolated normally open and normally closed contacts
for use in independent control circuits. Additional
features include LED trip, power, and inhibit indication,
autoreset or latching trips with front-panel and remote
reset, trip memory, test switch, self diagnostics, 0- to 5-V
analog output, inputs for standard and sensitive ground-
fault current transformers, CT verification for sensitive
current transformers, digital selector switches, switch-
selectable algorithms for fixed-frequency or variable-
frequency applications, and an inhibit that can be enabled
to prevent the output relay from operating during a high-
current ground fault.
Ground-fault current is sensed by a core-balance zero-
sequence current transformer (CT). The trip level of the
ground-fault circuit is switch selectable in 1% increments
from 1 to 99% of the CT-primary rating.
1.2 CURRENT-TRANSFORMER SELECTION
An SE-701 has inputs for 1-, 5-A, and sensitive 50-mA-
secondary CT’s. Choose a CT that provides the required
ground-fault-trip range.
For ground-fault detection, the ground-fault trip level
must be substantially below the prospective ground-fault
current. In a solidly grounded system, prospective ground-
fault current is similar to phase-fault current. In a resistance-
grounded system, prospective ground-fault current is
defined by the neutral-grounding-resistor let-through-current
rating.
In a solidly grounded system, protection against arcing
ground faults requires a ground-fault CT that will detect
low-level fault current but not saturate up to the operating
value of the system overcurrent protection. In general,
immunity to saturation is proportional to CT mass.
To eliminate nuisance tripping, surge current must not
saturate the CT.
For low-level ground-fault protection use an EFCT-1,
EFCT-2, or EFCT-26 sensitive earth-fault CT with a 5-A-
primary rating. However, protection at this level might not
be possible because of high surge current or prospective
ground-fault current.
For CT-selection assistance, see Technical Information
11.1 available at www.startco.ca
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 ground-fault circuit is not tripped. In the fail-
safe mode, non-volatile memory retains the trip status of
the SE-701. If tripped, and the supply voltage is cycled,
the SE-701 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 a ground-fault trip occurs. In the non-fail-safe
mode, trip status is not retained in non-volatile memory.
2.1.2 TRIP INHIBIT
Switch 2 is used to select Class I or Class II operation.
In the OFF position, high-current trip inhibit is off for
Class I operation. In the ON position, high-current inhibit
is on for Class II operation. If high-current trip inhibit is
on and ground-fault current escalates above eleven times
the CT-primary rating before the ground-fault circuit
trips, the output relay will not operate until ground-fault
current falls below eight times the CT-primary rating.
This feature allows overcurrent protection to operate in
applications where the ground-fault current can be larger
than the interrupting capacity of the device tripped by the
SE-701.
2.1.3 CT VERIFICATION
Switch 3 is used to enable CT verification with an
EFCT-series CT. In the ON position, a trip will occur if
the CT is disconnected. Switch 3 must be in the OFF
position when an EFCT-series CT is not used.
2.1.4 FILTER SELECTION
Switch 4 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 band width for fault
detection in variable-frequency drive applications.
2.1.5 RESET MODE
Switch 5 is used to select autoreset or latching trips.
See Section 2.2.3.

2.2 FRONT-PANEL CONTROLS
2.2.1 GROUND-FAULT TRIP LEVEL
The % CT PRIMARY selector switches are used to set
the ground-fault trip level as a percentage of the
CT-primary rating.
In tripping systems, a ground-fault trip level of 10 to
20% of the prospective ground-fault current is often used.
In alarm-only systems, a value of 50% of the prospective
ground-fault current is often used. To avoid sympathetic
tripping, the trip level must be above the charging current
of the protected feeder.
A 0% selection provides protection at 1%.
2.2.2 GROUND-FAULT TRIP TIME
The SE-701 has a definite-time trip characteristic. The
TIME (s) selector switch is used to set the ground-fault
trip delay time for coordination with upstream and
downstream ground-fault devices. Coordination requires
the same trip level for all ground-fault 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 ground-fault device to operate is the
one immediately upstream from the fault.
2.2.3 RESET
If the Reset Mode switch is in the LATCHING
position, a trip remains latched until the RESET switch is
pressed or the remote-reset terminals are momentarily
connected. In the non-fail-safe mode, cycling the supply
voltage will also reset the SE-701.
If the Reset Mode switch is in the AUTORESET
position, a trip will reset when the fault is removed.
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 (6 and 7) are connected.
2.2.4 TEST
The TEST switch is used to test the ground-fault
circuit, the indication, and the output relay. When the
TEST switch is pressed for one second, a test signal is
applied to the ground-fault-detection circuit, the circuit
will trip, the TRIP LED will light, and the output relay
will operate. If high-current inhibit has been selected, the
INHB LED will light.
2.3 FRONT-PANEL INDICATION
2.3.1 POWER
The green LED labeled PWR indicates the presence of
supply voltage.
2.3.2 TRIP
The red LED labeled TRIP indicates a trip. A solid red
LED indicates a ground-fault trip. A regularly flashing
LED indicates a trip initiated by a CT fault. Two fast
flashes indicate a diagnostic trip. See Section 2.5.
2.3.3 TRIP INHIBIT
The yellow LED labeled INHB indicates that output-
relay operation was inhibited during a high-current
ground fault. See Section 2.1.2. When a ground-fault
trip occurs during a high-current ground fault, both the
TRIP and INHB LED’s will be ON. Inhibit indication is
reset when the ground-fault trip is reset. Inhibit operation
and indication will not respond if the trip-inhibit switch is
in the OFF position.
2.4 ANALOG OUTPUT
The non-isolated, 0- to 5-V analog output indicates
ground-fault current sensed by the ground-fault CT. The
output is 5 V when ground-fault current is 100% of the
CT-primary rating.
2.5 SELF DIAGNOSTICS
A diagnostic trip is indicated by two flashes of the
TRIP LED. It can be caused by a diagnostic problem
detected by the watchdog timer or from an incorrect
reading from non-volatile memory. Press RESET or
cycle supply voltage. If the problem persists, consult
Startco.
3. INSTALLATION
An SE-701 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.
Pass the phase conductors through the CT window as
shown in Fig. 2 (for 4-wire and single-phase systems, also
pass the neutral conductor through the CT window). Do
not pass ground conductors through the CT window. In
applications that require shields or drain wires to pass
through the CT window, return them through the CT
window before connecting them to ground. If a ground
fault CT with a 5-A secondary is used, connect it to
terminals 2 and 3 (terminals 1 and 3 with a 1-A
secondary) and ground terminal 3. If an EFCT-x is used,
connect it to terminals 4 and 5, connect the shield to
terminal 5, and ground terminal 5. Remove the
connection to terminal 9 for dielectric-strength testing
—all inputs and outputs have ANSI/IEEE C37.90 surge-
protection circuits that conduct above 300 Vac. See
Figs. 3, 4, and 5 for sensitive EFCT-x dimensional
drawings.

4. SE-701 COMPATIBILITY
The current SE-701 has been enhanced with the
addition of non-volatile trip memory for the fail-safe
relay operating mode. Prior to hardware revision 07, a
mechanical flag was used instead of non-volatile trip
memory. The current revision of the SE-701 can
directly replace previous revision 00 to 06 units. The
hardware-revision number is listed on the SE-701
model/serial-number label affixed to the SE-701
enclosure. Both generations of SE-701 are compared
in Table 1.

8. GROUND-FAULT PERFORMANCE TEST
To meet the requirements of the National Electrical
Code (NEC), as applicable, the overall ground-fault
protection system requires a performance test when first
installed. A written record of the performance test is to
be retained by those in charge of the electrical
installation in order to make it available to the authority
having jurisdiction. A test-record form is provided for
recording the date and the final 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 ground-fault current
transformer. Ensure the cables pass through the
ground-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-701 is not polarity sensitive.
c) Verify that the system is correctly grounded and that
alternate ground paths do not exist that bypass the
current transformer. High-voltage testers and
resistance bridges can be used to determine the
existence of alternate ground paths.
d) Verify proper reaction of the circuit-interrupting
device in response to a simulated or controlled
ground-fault current. To simulate ground-fault
current, use CT-primary current injection. Fig. 8 (a)
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. Set the test current to 120% of
the SE-701 setting. Fig. 8 (b) shows a test circuit
using a Startco SE-100T Ground-Fault-Relay Tester.
The SE-100T provides a test current of 0.65 or 2.75
A for testing 0.5- and 2.0-A trip levels. 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 1, 2, 3, 4, and 5.
