Use - commissioningCommissioningChecking priorto commissioningThese operations must be carried out beforeSepam 2000 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,4321A+24-30 48-125 220-250V-DCc earthingCheck that the Sepam 2000 chassis is earthed bythe ground nut situated on the Sepam side panel,on the power supply side.Check that the screw is tightened.c cartridgev Check that the cartridge is in its slot behind the frontwicket door. To do so, open the wicket door by pullingon the notch situated on the left side panel.The Sepam S36 or S35 has a shield on the right,which resembles the memory cartridge wicket door.This shield is not another wicket door.Do not try to open it. Check that the cartridge hasbeen inserted correctly.Check the tightening of the 2 threaded screwsby hand. Above all do not insert or removethe cartridge when Sepam 2000 is energized,v the cartridge has an identification label on the front.The first 5 characters in the first line indicatethe Sepam 2000 model. Ensure that the typeof cartridge matches the Sepam model indicatedon the side of Sepam.ExampleS26L X on the cartridgelabel should matchS26LX on the Sepamlabel.c connectorsCheck that all theconnectors are correctlyconnected to the rearof the device and screwlocked.MERLIN GERINS26 LX S014LXS01FA161SFAMERLIN GERINSEPAM 2026S26 LX J2 TBN*** *Setting of microswitches on the rear of the device.Check that the microswitches which define operatingmodes and Sepam 2000 calibration operations werecorrectly set at the time of installation (1) .The microswitches must be set with Sepamde-energized.If the microswitches are incorrectly set, themeasurements given by Sepam 2000 will beerroneous and the protections will fail to trip at thedesired set points.Default parameter settingFactory-set parameter status:c microswitches:v they are set for a 5A secondary current transformer power supply,v residual current measurement by the core balance CT,v residual voltage measurement by the sum of the 3 voltages,c protection:v settings: 999 kA or kVv time delays: 655 sc program logic time delay:v t = 200 ms,v number of starts (motor protection):v N = 999,v time between starts = 0.5 sCommissioning using the pocket terminalSwitch on the SepamAfter the Sepam 2000 has started up, check that no messages are present bypressing the “alarm” key.Checking modeAll the data may be accessed for checking purposes without the risk of changingparameters or settings.Parameter setting mode (2)This mode is reserved for commissioning and maintenance.The entry of a password is required.
