Tolerances have to be taken into account (measuring current transformers, RCMS…) whenever measurements are carried out. The IEC 62020 specifies that the set response value shall not be exceeded, therefore an RCMS… shall respond when 50…100 % of the set response value are reached. Prewarning is therefore to be signalled earlier (x % of 50…100 % of the response value). The current measuring channels k9…k12 of version RCMS…-D4/-L4 have positive tolerances as regards the response values.RCMS460-490_D00067_03_M_XXEN/12.201761OperationDepending on the settings in the "Channel -> Mode" menu and "Channel -> CT" menu the following response values can be selected:Type AB Type A Flex. Digital inputs10 mA…10 A (DC…2000 Hz) 6 mA…20 A (42…2000 Hz) 100 mA…30 A (42…2000 Hz) 0/1Resolution of setting type AB(AC/DC sensitive measuring current transformers):Measuring current transformers W20AB measure residual currents in the range AC/DC 10…500 mA.
