SE-330HV Neutral-Grounding-Resistor Monitor Rev. 5-I-091115
4. DATA INTERFACES
4.1 SD C
ARD
The SE-330HV supports microSD™ data storage.
The microSD™ card port is located on the front panel
just below the USB port. The microSD™ card is used
for long-term data logging of measured values and for
firmware upgrades.
4.1.1 D
ATALOGGING
When a microSD™ card is installed, the SE-330HV
looks for a directory called “Datalogging”. If this
directory exists, data logging will automatically start
after the card is indexed (indexing may take several
minutes depending on the size of the card and the
number of files).
The log is updated every two seconds and it includes
measured values, configuration parameters, and trip
status. A new log file is created at the start of each day.
If previous log files exist and the microSD™ card has
less than 20 MB of free space, the oldest datalogging file
will automatically be deleted before a new file is created.
The red DIAGNOSTIC LED may indicate an SD Card
error. See Section 5. Approximately 3 GB of data is
generated per year of logging.
4.1.2 F
IRMWARE UPGRADE
Firmware upgrades are performed using a microSD™
card in conjunction with configuration switch S8. See
Section 2.1.4.6. The SE-Flash software is not required.
To upgrade the SE-330HV firmware, insert a
microSD™ card containing the firmware upgrade file
(.S19 format) in the root directory of the SD card and set
switch S8 to UPGRADE within 30 s of card installation.
If S8 is switched to UPGRADE after 30 s, the upgrade
process will not occur. If the microSD™ card is inserted
after S8 is switched to UPGRADE, switch S8 to RUN
and then back to UPGRADE. The SE-330HV evaluates
firmware upgrade files found in the root directory of the
microSD™ card and uses the first valid file.
Ensure that the DIAGNOSTIC LED is off before
beginning the firmware upgrade process.
The red DIAGNOSTIC LED blinks rapidly while the
firmware upgrade is running and the SE-330HV will
restart when the upgrade is complete. If the upgrade is
not successful, the DIAGNOSTIC LED will indicate an
SD Upgrade Error. See Section 5. Set switch S8 back to
RUN for normal operation. If a firmware upgrade fails,
the existing firmware is not overwritten.
A record of the upgrade can be found in
“upgrade_log_<SN>.txt” on the microSD™ card. This
file is updated each time an upgrade is performed.
N
OTE: The included microSD™ card has a temperature
rating of -25 to 85°C (-13 to 140°F). For applications
colder than -25°C (-13°F), use an Industrial-Grade
microSD™ card.
N
OTE: The maximum recommended microSD™ card
storage capacity is 4 GB.
4.2 USB INTERFACE
Use the SE-MON330 software (version 3.5 or newer)
to access set-points, measured values, and trip records
through the mini B USB interface located on the front
panel. The following data can be viewed:
 Front-panel and configuration-switch settings
 Neutral voltage and neutral current
 Resistance change from the calibrated value
 Trip status
 Trip records, 100 date and time stamped
 Firmware version and serial number
The following values can be viewed and adjusted:
 Ground-fault trip setting (when front-panel GF Trip
Level is set to MEM)
 K2 ground-fault relay output operating mode
 K3 resistor-fault relay output operating mode
 Clock settings
 Trip records can be cleared
 Remote calibration
 Resistor-fault trip time
 Resistor-fault trip level
 Geo-magnetic filter
Ensure the real-time clock is set to the correct time
prior to normal operation. Trip records and on-board
datalogging information include date and time readings
from the clock. Refer to the SE-MON330 software help
file.

ETWORK COMMUNICATIONS
The optional communications interfaces include a
single CAN port and dual Ethernet ports supporting
cable, fiber
(1)
, or both cable and fiber. Protocols include:
 DeviceNet over CAN (ordering option 1)
 EtherNet/IP over cable or fiber (ordering options 3,
4, and 5)
 Modbus TCP over cable or fiber (ordering options 3,
4, and 5)
 IEC 61850 over cable or fiber (ordering options 6, 7,
and 8)
Refer to the appropriate SE-330HV communications-
interface manual for details.
