Parameter and setting errorsChanging a status parameter may put a protectionsetting outside the tolerance range.Sepam detects the problem and displays the followingmessage:P\CT ratioprotection settingout of rangepress clear keyThe user should then check and, if necessary, changethe protection settings. The PROTECTION line blinksuntil the settings have been corrected.Settings out of range.A protection value may be out of range when it is set.Sepam detects this and indicates the permissiblerange of settings.P\Earth fault/S1 F081Iso out of range0.05Ino < Iso < InoPress clear keyExample: 50N, 51N earth protection.All the parameters and settings are accessiblein 3 menus:v general parameters: status menu,v protection: protection menu,v operating parameters: program logic menu,General parametersThe general parameters are accessible in the statusmenu; they are to be set at the time of commissioningand must not be modified during current operation.HV/MV substation Installation - Use - CommissioningStatus menu parameter chartheading name function command selectionfrequency Fn network frequency data + and - 50 or 60 HzPhase CT In CT rating numeric adjustable fromratio keys 10 A to 6250 Aphase CT' Ib basis current of numeric 0.4 to 1.3Inratio equip. being protected keys in ampsnumber number of current data + and - 2 or 3 sensorssensorsphase CT In CT rating (standard data + and - 30 values betweenratio for CSP values see table on 30 A and 2500 Athe next page)Ib basic current of the numeric 0.4In to 1.3Inequipment being protected keys in amperesnumber number of data + and - 2 or 3 sensorscurrent sensorsIo sensor Ino residual current data + and - TC:I'o sensor measurement b sum of 3ICPS:b sum1 3Ior sum2 3Ib 2 A or 30 A corebalance CTS26, S36 b CT + CSH30numeric Ino adjustable fromkeys 1 A to 6250 AS25, S35 b 56 values fromdata + and - 1 A to 6250 Amax. period max. demand integration data + and - adjustable from:interval period 5, 10, 15, 30, 60 mnphase VT number number of VTs wirred data + and - S26-S36 S25-S35phase VT’ V U211U U21-U323U 3UUnp rated VT primary numeric adjustable fromvoltage keys 220 V to 250 kVUns rated VT secondary data + and - 100, 110, 115,voltage120 VVnso type of residual data + and - b sum of 3Vstvoltage measurement b Uns / 3b Uns / 3direction of incomer reverses the signs data + and - incomer:energy feeder of power and energy cable --> busbars (1)measurementsfeeder:busbars --> cable (1)communi- speed transmission speed data + and - 300, 600, 1200,cation (2) 2400, 4800, 9600,19200, 38400 bdsstation number of Sepams in numeric 1 to 255the networkkeysparity transmission format data + and - even, odd,without paritytime synchro type of synchronization data + and - via:tagging (2) used - network- inputs I11 or I21(3)events I1 I2 numericI11 to I18keysI21 to I28I31 to I38KTS1 to KTS32 by network 8 bitsKTS33 to KTS64 for S26, S36onlypasswordsee correspondingpage(1)incomer + , feeder +(2)for commissioning, refer to “communication” document.(3)0 = not time-tagged1 = time-tagged.All events are set to zero by default.2/11
