SE-601 DC Ground-Fault Monitor
Rev. 2-C-073123

1. GENERAL
The SE-601 is a microprocessor-based ground-fault
monitor for ungrounded dc systems. Its output relay can
operate in the fail-safe or non-fail-safe mode for
undervoltage or shunt-trip applications. The SE-601 has
one output relay with isolated normally open and normally
closed contacts for use in independent control circuits.
Additional features include LED power and faulted-bus
indication, autoreset or latching trips with front-panel and
remote reset, trip memory, test button, self diagnostics,
0- to 5-V analog output, and digital selector switches. The
SE-601 can be DIN-rail, surface, or panel mounted.
Ground-fault current is sensed using an SE-GRM-series
Ground-Reference Module—a resistor network that limits
ground-fault current to 25 mA. The trip level of the ground-
fault circuit is selectable from 1 to 20 mA. Trip time is
selectable from 0.05 to 2.5 s.
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 SE-601 is energized and the ground-fault circuit is not
tripped. If tripped, and the supply voltage is cycled, the
SE-601 will remain tripped, with the trip relay de-energized
and a TRIP LED on, until reset.
In the non-fail-safe mode, the output 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 RESET MODE
Switch 2 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 LEVEL (mA) selector switch is used to set the
ground-fault trip level.
Ground-fault current is a function of fault resistance,
system voltage, and the SE-GRM-series Ground-Reference
Module. Table 1 lists the SE-601 trip levels and fault-
resistance values for 24-, 48-, 125-, 250-, 500-, 780-, 1000-,
and 1500-Vdc systems.
2.2.2 GROUND-FAULT TRIP TIME
The SE-601 has a definite-time trip characteristic. The
TIME (s) selector switch is used to set the ground-fault trip
time.
2.2.3 RESET
If the Reset Mode switch is in the LATCHING position,
a trip remains latched until the RESET button is pressed or
the remote-reset terminals (6 and 7) are momentarily
connected. In the non-fail-safe mode, cycling the supply
voltage will also reset the SE-601.
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 button will not prevent a trip. The
front-panel RESET button is inoperative when remote-reset
terminals are connected.
2.2.4 TEST
The TEST button is used to test the ground-fault circuit,
trip indication, and the output relay. When the TEST button
is pressed for one second, a test signal is applied to the
ground-fault-detection circuit, the circuit will trip, both
“-BUS”and “+BUS” TRIP LED’s will light, and the output
relay will operate.

2.3 FRONT-PANEL INDICATION
2.3.1 POWER
The green LED labelled PWR indicates presence of the
supply voltage.
2.3.2 TRIP
The red TRIP LED's indicate a ground-fault trip. The
“-BUS” TRIP LED indicates a ground fault on the negative
dc bus. The “+BUS” TRIP LED indicates a ground fault on
the positive dc bus. Two fast flashes indicate a diagnostic
trip. See Section 2.5
2.4 ANALOG OUTPUT
The non-isolated, 0- to 5-V analog output indicates
ground-fault current. The output is 5 V when ground-fault
current is 20 mA. Use a PGA-0500 Analog Percent Current
Meter with the PGA-05CV Voltage Converter to indicate
ground-fault current. See Figs. 2 and 8.
2.5 SELF DIAGNOSTICS
A diagnostic trip is indicated by two fast flashes of the
TRIP LED’s. It can be caused by a diagnostic problem
detected by an incorrect reading from non-volatile memory.
Press RESET or cycle supply voltage. If problems persist,
contact Littelfuse.
3. INSTALLATION
3.1 SE-601
An SE-601 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.
Connect the SE-601 DC Ground-Fault Monitor and
SE-GRM-series Ground-Reference Module as shown in
Fig. 2.
Remove the connection to terminals 5 and 9 for
dielectric-strength testing—all inputs and outputs have
ANSI/IEEE C37.90 surge-protection circuits that conduct
above 300 Vac.
3.2 GROUND-REFERENCE MODULES
Outline and mounting dimensions for the SE-GRM-series
Ground-Reference Modules are provided in Figs. 3, 4, and
5.
Ground-Reference Modules dissipate heat during normal
operating conditions and when a ground fault is present. An
additional heat sink may be required. See Section 5.2 for
details. When using an additional heat sink, apply thermal
compound (silicone grease) to the Ground-Reference
Module’s mounting surface, then securely fasten it to the
heat sink surface.

4. SE-601 COMPATIBILITY
The SE-601 has been enhanced with the addition of
non-volatile trip memory for the fail-safe relay operating
mode. Prior to hardware revision 01, a mechanical flag
was used instead of non-volatile memory. The current
revision of the SE-601 can directly replace previous
revision-00 units. The hardware-revision number is
listed on the SE-601 model/serial-number label affixed to
the SE-601 enclosure. Both generations are compared in
Table 2.

7. WARRANTY
The SE-601 DC Ground-Fault Monitor and associated
SE-GRM Ground-Reference Module is warranted to be
free from defects in material and workmanship for a
period of five years from the date of purchase.
Littelfuse will (at Littelfuse’s option) repair, replace,
or refund the original purchase price of an SE-601 that is
determined by Littelfuse to be defective if it is returned
to the 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. Littelfuse
does not warrant products repaired or modified by non-
Littelfuse personnel.
8. GROUND-FAULT PERFORMANCE TEST
A test record form is provided for recording the date
and the final results of the performance tests. The
following ground-fault system test is to be conducted by
qualified personnel.
a) Evaluate the interconnected system in accordance
with the overall equipment manufacturer’s detailed
instructions.
b) Verify proper reaction of the device in response to a
simulated or complete system test.
c) To simulate a ground fault, power down the entire
system and remove the connection to terminal 4 (S).
Ensure that terminal 5 is connected to ground. Using
a 24 Vdc source, 50 kΩvariable resistor, fixed 1 kΩ
resistor, and an ammeter, connect the circuit as
shown in Fig. 9. Select a trip current on the SE-601,
and slowly vary the resistance until the monitor trips.
Never exceed 30 mA through the monitor.
d) For a system ground-fault test, install a fixed or
variable resistance and switch that is suitably rated
for the system. Install a fuse rated to protect the test
circuit. The fixed test resistance can be sized to
cause a ground-fault current just above the trip level
setting. See Fig. 10. For a reference of fault-
resistance values, see Table 1.
e) Record the date and the results of the test on the
attached test record form.
