Checking priorto commissioningThese operations must be carried out before Sepam2000 is energized.

Checks:c Supply voltageEnsure that the cubicle auxiliary supply voltagematches Sepam 2000's operating voltage. It isindicated on the rear of the device, beside the powersupply connector, by a dot in the voltage box,

c Earthing

Check that the Sepam 2000 chassis is earthed by thegrounding nut situated on the Sepam side panel, onthe power supply side. Check that the screw hasbeen tightened,c Cartridgev Check that the cartridge is in its slot behind the frontwicket door. To do so, open the door by pulling on thenotch situated on the left side panel. Sepam S35 hasa shield on the right, which resembles the memorycartridge door. This shield is not another door; do nottry to open it. Check, by hand, that the 2 threadedscrews have been tightened.Above all, do not insert or remove the cartridgewhen Sepam 2000 is energized,v the cartridge has an identification label on the front.The last 3 characters in the first line of the labelindicate the type of Sepam 2000 (the typecorresponds to the protection and metering functionsperformed). The first 5 characters in the label indicatethe Sepam 2000 model. Ensure that the type ofcartridge matches the Sepam model indicated on theside of Sepam.

ExampleS35CR on the cartridge label should match S35CRon the Sepam label.

Sepam comprises self-testing and self-diagnosisto facilitate installation maintenance.

Indicator lamps and displaymessagesc Green indicator lamp lit up Sepam is energized.c No indicator lamps lit upThere is probably an auxiliary power supply fault.

Check the auxiliary power supply and connections tothe CE40 board. Perform the lamp test.

c Red lamp indicates internal Sepam faults.Sepam continuously performs on-line internal tests.When the test results are negative, Sepamautomatically runs a series of sequences which resultin either:v automatic reinitialization (minor fault, e.g. transientauxiliary power supply break).Sepam carries out a complete restart sequence. Ifrestart is successful, Sepam operates again normally.All the output relays arede-energized (1),v switching to the fail-safe position. All the outputrelays drop out (1) in order to avoid inadvertentcommands, and the watchdog drops out as well.

The following may cause internal faults:c Missing cartridge:v red indicator lamp lit up,v display OFF,v no dialogue with TSM2001 pocket terminal,v no dialogue with communication link,v watchdog dropped out,v switching to fail-safe position.Sepam 2000 will not start, lacking a program: this is amajor fault,

c Configuration fault:v red indicator lamp lit up,v red lamp indicates CARTRIDGE,v no dialogue with the TSM2001 pocket terminal,v no dialogue with the communication link,v the watchdog is dropped out,v switching to fail-safe position.Sepam 2000 is shut down: this is a major fault.v The type of cartridge is not compatible with theSepam model.

Caution: do not insert or remove the cartridgewhile Sepam is energized.v Disconnect the auxiliary power supply and wait 2seconds before handling the cartridge.

Check the references on the Sepam and on thecartridge (refer to chapter on Sepam identification).

v Sepam is automatically disabled until theappropriate cartridge is installed.

(1) this may cause tripping with undervoltage control logic ("fail-safe" logic).

c Other major faults:v red indicator lit up,v display indicates MAINTENANCE or CARTRIDGE,v no dialogue with the TSM2001 pocket terminal,v no dialogue with the communication link (if the CPU is faulty),v the watchdog is dropped out,v switching to the fail-safe position.Sepam 2000 is shut down: this is a major fault.

Consult your maintenance department.

c Minor or partial fault:v red indicator extinguished,v display indicates MAINTENANCE or CARTRIDGE,v dialogue with the TSM2001 pocket terminal is maintained,v dialogue with the communication link is maintained,v the watchdog does not drop out.Sepam 2000 is operating, however it has detected a transient fault or one of thecomponents has failed to pass self-testing.


Communication indicator lampsThese lamps are located at the rear of the device on the CE40 module when themodule is equipped with the communication option.c Green indicator lamp blinking: indicates traffic on the line.This is the normal operating mode.c Indicator lamps extinguished: There is no communication.

Check the cabling and inquiries at the level above.

c Red indicator lamp lit:

indicates initialization of the coupler, which lasts about 2 seconds, or a couplerfault.

Set the parameters(use the setting sheets which are included in theappendix to record the values)c Statusc Control logicc Differential protection setting

Perform testingDifferent test methods are proposed:c Differential protection testing with simplifiedparameterization.

This parameterization may be used to check theprotection operating curve using two single-phaseinjection units. The outputs used for tripping andindication are disabled, which makes it possible tocarry out this test while the network is operatingnormally.c Cabling testing by current injection:correct cabling and parameterization of the differentialprotection may be checked by injecting a knowncurrent in the protection and reading the phasecurrents, differential currents and restrained currentsmeasured by the protectionAt the time of start-up, this test is the only one that isrequired.c Restricted earth fault protection test.

Inhibition of outputsand test parameterization

Disabling of outputsIt is useful to be able to inhibit differential protection actions, in particular to runtests while the electrical distribution system is operating normally.

Parameter KP9 is used for inhibition. It consists of disabling differential protectionswitching of outputs O1, O2, O12 and O13, assigned to tripping and indication.

Output O14 (differenital protection indication) remains valid and is used to testprotection operation.

KP6 = 0 KP9 = 0 No inhibition Outputs: all validIndicator: -Message : ------------

KP9 = 1 Inhibition Outputs: O1 - O2 - O12 - O13not activated by differentialO11 - O14 validIndicator: test lit upMessage: INHIBIT.

Test modeThe test mode is designed to simplify current injection for the differential protectiontest.

The test mode is obtained by using the KP6 parameter. The changeover to testmode automatically parameterizes a Dd0 coupling and a rated transformer currentIb = In and Ib' = In' and invalidates the switching of the O1 - O2 - O12 - O13outputs. Upon the return to normal mode (KP6 = 0), the initial parameter settingsare recovered and the outputs become active again.

Changeover from normal mode to test mode: KP6 = 1
