User-Machine Interface
Two types of User-Machine Interfaces ( UMI) are available for Sepam series 80 base
units:
b mimic-based UMI
b advanced UMI.
The advanced UMI can be integrated in the base unit or installed remotely on the
cubicle. Integrated and remote advanced UMIs offer the same functions.
A Sepam series 80 with a remote advanced UMI is made up of:
b a bare base unit without any UMI, for mounting inside the LV compartment
b a remote advanced UMI ( DSM303)
v for flush mounting on the front panel of the cubicle in the location most suitable for
the facility manager
v for connection to the Sepam base unit using a prefabricated CCA77x cord.
The characteristics of the remote advanced UMI module ( DSM303) are presented on
page 162.
Comprehensive data for facility managers
All the data required for local equipment operation may be displayed on demand:
b display of all measurement and diagnosis data in numerical format with units
and/ or in bar graphs
b display of operating and alarm messages, with alarm acknowledgment and Sepam
resetting
b display of the list of activated protection functions and the main settings of major
protection functions
b adaptation of activated protection function set points or time delays in response to
new operating constraints
b display of Sepam and remote module versions
b output testing and logic input status display
b display of Logipam data: status of variables, timers
b entry of 2 passwords to protect parameter and protection settings.
Local control of devices using the mimic-based UMI
The mimic-based UMI provides the same functions as the advanced UMI as well as
local control of devices:
b selection of the Sepam control mode
b view device status on the animated mimic diagram
b local opening and closing of all the devices controlled by Sepam.
Ergonomic data presentation
b keypad keys identified by pictograms for intuitive navigation
b menu-guided access to data
b graphical LCD screen to display any character or symbol
b excellent display quality under all lighting conditions : automatic contrast setting
and backlit screen ( user activated) .
Working language
All the texts and messages displayed on the advanced UMI or on the mimic-based
UMI are available in 2 languages:
b English, the default working language
b and a second language, which may be
v French
v Spanish
v another " local" language.
Please contact us regarding local language customization.
Connection of Sepam to the parameter setting tool
The SFT2841 parameter setting tool is required for Sepam protection and parameter
setting.
A PC containing the SFT2841 software is connected to the RS 232 communication
port on the front of the unit.

Hardware characteristics
Removable memory cartridge
The cartridge contains all the Sepam characteristics:
b all Sepam protection and parameter settings
b all the metering and protection functions required for the application
b predefined control functions
b functions customized by control matrix or logic equations
b functions programmed by Logipam ( optional)
b personalized local-control mimic diagram
b accumulated energies and switchgear diagnosis values
b working languages, customized and otherwise.
It may be made tamper-proof by lead sealing.
It is removable and easy to access on the front panel of Sepam to reduce
maintenance time.
If a base unit fails, simply:
b switch off Sepam and unplug connectors
b retrieve original cartridge
b replace the faulty base unit by a spare base unit ( without cartridge)
b load the original cartridge into the new base unit
b plug in the connectors and switch Sepam on again:
Sepam is operational, with all its standard and customized functions, without
requiring any reloading of protection and parameter settings.
Backup battery
Standard lithium battery, 1/ 2 AA format, 3.6 Volts.
It allows the following data to be stored in the event of an auxiliary power outage:
b time-tagged event tables
b disturbance recording data
b peak demands, tripping context, etc
b date and time.
The battery presence and charge are monitored by Sepam.
The main data ( e.g. protection and parameter settings) are saved in the event of an
auxiliary power outage, regardless of the state of the battery.
Auxiliary power supply
DC power supply voltage from 24 to 250 V DC.
Five relay outputs
The 5 relay outputs O1 to O5 on the base unit must be connected to connector
A . Each output can be assigned to a predetermined function using the SFT2841
software.
O1 to O4 are 4 control outputs with one NO contact, used by default for the
switchgear control function:
b O1: switchgear tripping
b O2: switchgear closing inhibition
b O3: switchgear closing
b O4: available.
O5 is an indication output used by default for the watchdog function and has two
contacts, one NC and one NO.
