Note 1 The measured residual current is available only for NA11 protection relays equipped with standard CTs sensor inputs
Note 2 The measured residual current is available only for NA11 protection relays equipped with standard CTs sensor inputs
Note 3 The computed residual current I
EC
(vector sum of the phase currents) is available for NA11 protection relays equipped with LPCT sensor in-
puts
Note 4 The temperature measuring is acquired by means of RTD probes Pt100 (eight Pt100 inputs with one MPT module); if the module is not available
the concerning measure is meaningless
Note 5 The K7...K10 and IN3...IN42 state is meaningful only when the corresponding I/O circuits are available (MRI and MID16 modules)
Note 6 With ThySetter V3.4.3 and IEC 61131-3 compiler V1.2.7, at presently only the IL language (Instruction List) is implemented;
other languages, according the IEC 61131 standard - ST (Structured Text), LD (Ladder Diagram), FBD (Function Block Diagram), SFC (Sequential
Functional Chart), will be available in the next future
Note 7 The state is acquired downstream the tON and tOFF timers
