Sepam parameter and protection setting
The parameter and protection setting of a Sepam
using SFT2841 consists of preparing the Sepam file
containing all the characteristics that are specific to
the application, a file that is then downloaded into
Sepam at the time of commissioning.
CAUTION
HAZARD OF UNINTENDED OPERATION
b The device must only be configured and set by
qualified personnel, using the results of the
installation protection system study.
b During commissioning of the installation and
after any modification, check that the Sepam
configuration and protection function settings are
consistent with the results of this study.
Failure to follow these instructions can cause
equipment damage.
Operating mode:
1. Create a Sepam file for the type of Sepam to be
set up. (The newly created file contains the Sepam
factory-set parameter and protection settings).
2. Modify the "Sepam" page function sheet
parameters and the "Protections" page function
sheet protection settings:
b All the information relating to a function is
grouped together on a single screen
b We recommend entering all the parameter and
protection settings in the natural screen order
suggested by the guided navigation tool.
Entry of parameter and protection settings
b The parameter and protection setting input fields
correspond to the type of value:
v selection buttons
v numerical value input fields
v dialog box (Combo box)
b The modifications made to a function sheet are to be
"Applied" or "Canceled" before the user goes on to the
following function sheet
b The consistency of the parameter and protection
settings entered is checked:
v a clear message specifies the inconsistent value in
the function sheet opened
v values which become inconsistent following the
modification of a parameter are replaced by "****" and
must be corrected.

Precaution
When a laptop is used, given the risks inherent in the accumulation of static
electricity, the customary precaution consists of discharging in contact with an
earthed metal frame before physically connecting the CCA783 cord.
Note: If you are unable to connect to Sepam, check that the SFT2841 software version used is
actually compatible with your Sepam.
(see “Compatibility of Sepam version/SFT2841 version” page 7/35).
Plugging into Sepam
b Plug the 9-pin connector (SUB-D type) into one of the PC communication ports.
Configure the PC communication port via the "Communication port" function in the
"Options" menu.
b Plug the 6-pin connector (round minidin type) into the connector situated behind
the blanking plate on the front panel of Sepam or the DSM303 module.
Connection to Sepam
2 possibilities for setting up the connection between SFT2841 and the Sepam:
b Choice of "Connect to the Sepam" at the start-up of SFT2841
b "Connection" function in the "File" menu.
Once the connection with Sepam has been established, "Connected" appears in the
status bar, and the Sepam connection window can be accessed in the work zone.
User identification
The window intended for the entry of the 4-digit password is activated:
b Via the "Passwords" tab
b Via the "Identification" function in the "Sepam" menu
b Via the "Identification" icon .
The "Return to Operating mode" function in the "Passwords" tab removes access
rights to parameter and protection setting mode.
Downloading of parameters and protection settings
Parameter and protection setting files can only be downloaded to the connected
Sepam in Parameter setting mode.
Once the connection has been established, the procedure for downloading a
parameter and protection setting file is as follows:
1. Activate the "Download Sepam" function in the "Sepam" menu.
2. Select the *.rpg file which contains the data to be downloaded.
3. Acknowledge the end of operation report.
Return to factory settings
This operation is only possible in Parameter setting mode, via the "Sepam" menu. All
the Sepam general characteristics, protection settings and the control matrix go back
to the default values.
Uploading of parameters and protection settings
The connected Sepam parameter and protection setting file can only be uploaded in
Operating mode.
Once the connection has been established, the procedure for uploading a parameter
and protection setting file is as follows:
1. Activate the "Upload Sepam" function in the "Sepam" menu.
2. Select the *.rpg file that is to contain the data to be uploaded.
3. Acknowledge the end of operation report.
Local operation of Sepam
Connected to Sepam, SFT2841 offers all the local operating functions available in
the advanced UMI screen, plus the following functions:
b Setting of Sepam internal clock, via the "General characteristics" tab. It should be
noted that Sepam saves the date and time, in case the auxiliary power supply fails
(< 24 hours)
b Implementation of the disturbance recording function, via the "OPG" menu:
validation/inhibition of the function, recovery of Sepam files, start-up of SFT2826
b Consultation of the history of the last 64 Sepam alarms, with time-tagging
b Access to Sepam diagnostic data, in the "Sepam" tab box, included in "Sepam
diagnosis".
In Parameter setting mode, the switchgear diagnostic values can be modified:
operation counter, cumulative breaking current to reset the values after a change of
breaking device.
