Basic Relay Operations
Reading Oscillograms, Event Reports, and SER
Step 4. Download the file. Perform the steps necessary for your terminal
emulation program to receive a file.
Typically, these are the file transfer steps:
➢ Specify the destination file location in your computer file
storage system and file name.
➢ Select the transfer type as YModem (if not already enabled).
➢ Click Receive.
You will usually see a confirmation message when the file transfer is
complete.
Step 5. When this file has transferred successfully, use Analytic Assistant or
SYNCHROWAVE Event to play back the event report oscillograms of
the 8-samples/cycle event report file you just transferred.
Viewing SER Records
The relay SER records relay operating changes and relay element states. In
response to an element change of state, the SER logs the element, the element
state, and a time stamp. Program the relay elements that the relay stores in the
SER records, thus capturing significant system events such as an input/output
change of state, element pickup/dropout, recloser state changes, etc.
The relay stores the latest 1000 entries to a nonvolatile record. Use the relay com-
munications ports or QuickSet to view the SER records. For more information on
the SER, see Section 9: Reporting.
The latest 200 SER events are viewable from the front panel. For more informa-
tion, see Section 4: Front-Panel Operations.
Setting the SER and Examining an SER Record in QuickSet
The procedure in the following steps shows you how to use QuickSet to program
relay elements into the SER. Also, use these procedures to review SER records
with QuickSet.
This example assumes that you have successfully established communication
with the relay (see Making an EIA-232 Serial Port Connection on page 3.4). In
addition, you must be familiar with relay access levels and passwords (see
Changing the Default Passwords in the Terminal on page 3.10 to change the
default access level passwords). You should also be familiar with QuickSet (see
Section 2: PC Software).
Step 1. Start QuickSet and establish a connection with the relay. See Step 1
and Step 2 of Checking Relay Status in QuickSet on page 3.12 for
detailed steps.
Step 2. Download the present configuration in the relay by clicking File > Read.
The relay sends all configuration and settings data to QuickSet.
Step 3. Click the Report branch of the QuickSet Settings tree view structure
(see Figure 3.48) to view the SER settings entry screen.
You will see the SER Points and Aliases window similar to
Figure 3.49.
