6. If IPScom returns an error message,
then determine the relay COM1
communication parameters as follows:
a. From the relay Front Panel HMI
press
ENTER
. The relay will display:
VOLTAGE RELAY
VOLT curr freq v/hz
b. Press the right arrow pushbutton
until the relay displays:
COMMUNICATION
W
stat COMM setup
V
c. Press
ENTER
. The relay will
display:
COM1 SETUP
COM1 com2 com3 com_adr
V
d. Press
ENTER
. The relay will
display:
COM1 BAUD RATE
W
baud_4800 baud_9600
Record the Baud Rate that is displayed
in all Caps: __________
e. Pres
EXIT
as necessary to exit
the HMI.
f. Select the
Connect
menu item.
IPScom will display the
Serial Port
Dialog Screen (Figure 3‑6).
g. Verify the IPScom COM Port Baud
Rate is the same as relay COM1
Baud Rate.
h. Verify that the
PC Comm Port
that is connected to the relay is
selected.
i. Select
Connect
. This action will
attempt to establish communication.
j. If IPScom returns a “COM Opened
and Level #(1, 2 or 3) access
granted” then communications have
been established. Enter any valid
ISScom command(s) as desired.
To close the communication channel when
connected locally, select Communication/
Disconnect from the main screen menu
bar.
5.9 Initial Setup Procedure
The M‑3425A Generator Protection Relay is shipped
from the factory with all functions disabled (user will
only be able to enable purchased functions).
The Setup Procedure provided below is a suggested
setup procedure for initially entering settings into the
relay. While it is written for HMI‑equipped units, the
same procedure is applicable when setting the relay
through remote communication utilizing S‑3400
IPScom
®
Communications Software.
Following the Setup Procedure are several sections
which provide additional detail concerning the
settings required for proper commissioning.
Setup Procedure

NOTE
: Configuration Record forms are available in
Appendix A, Configuration Record Forms,
to record settings for future reference.
1. Connect power to the relay’s rear power
terminals, as marked on the rear panel’s
power supply label and as shown in
Figures 5‑7 and 5‑8.
2. When power is initially applied, the
M‑3425A performs a number of self‑tests
to ensure its proper operation. During
the self‑tests, an “X” is displayed for
each test successfully executed. If all
tests are successful, the unit will briefly
display the word
PASS
. Then, a series
of status screens, including the model
number, software version number, serial
number, date and time as set in the
system clock, and the user logo screen
will be displayed. (Figure 2‑2 illustrates
this sequence of screens.)
3. If any test should fail, the DIAG LED will
flash the error code, or the error code will
be displayed on units equipped with the
HMI and the relay will not allow operation
to proceed. In such a case, the error
code should be noted and the factory
contacted. A list of error codes and their
descriptions are provided in Appendix
C,
Error Codes
. Assuming that various
voltage functions are enabled, and
there are no voltage inputs connected,
various voltage targets will be identified
as having operated
4. If remote communication is used, the baud
rate, address, and other parameters for the
communication ports must be set. Refer to
the instructions in Section 5.8, A ctivating
Initial Local Communications
. Also
refer to
