Use - commissioningCommissioningChecking priorto commissioningThese operation must be carried out beforeSepam 2000 S46 is energized.Checksc Supply voltage.Ensure that the auxiliary supply voltage matchesSepam 2000’s operating voltage. It is indicatedon the rear of the device, beside the power supplyconnector, by a dot in the voltage box. The supplyvoltage is also marked on the ETOR logic inputboards.v the cartridge has an identification label on the front. The last 3 charactersin the first line of the label indicate the type of Sepam 2000 (the type correspondsto the functions performed). Ensure that the type matches the Sepam modelindicated on the side of Sepam.ExampleS46 XR on the cartridge label should match S46 XR on the Sepam label.S46 XR R078XRR07AA363RAA4321A+24-30 48-125 220-250V-DCSEPAM 2046S46 XR X7 TBN*** *c Earthing.Check that the Sepam 2000 chassis is earthedby the ground nut situation on the Sepam side panel,on the power supply side.c Cartridge.v Check that the cartridge is in its slot behind the frontwicket door. To do so, open the wicket door by pullingon the notch situation on the left side panel.The Sepam S46 has 2 shields on the right whichresemble the memory cartridge wicket door. Theseshields are not wicket doors and the user should nottry to open them. Check that the cartridge is fullyinserted. Check the tightening of the 2 threadedscrews by hand.Above all, do not insert or removethe cartridge while Sepam 2000is energized.c ConnectorCheck that the connectors are correctly connected to the rear of the deviceand screwed on.Setting of microswitches on rearCheck that the microswitches which define operating modes and Sepamcalibration operations were correctly set at the time of installation (1) .The microswitches must be set with Sepam de-energizedIf the microswitches are incorrectly set, the measurements given by Sepam 2000will be false.Default parameter settingFactory-set parameter status:c microswitches:v they are set for supply by a 5 A secondary current transformer,c protection and monitoring:v set points inhibited,v control logic time delay: t = 200 ms.(1)see “installation, connection of current and voltage inputs” chapter.2/8 Installation - Use - Sheets
