    2. Safety instructions 2.1 General safety instructions Part of the device documentation in addition to this manual is the enclosed "Safety instructions for Bender products". 2.2 Work activities on electrical installations Only qualified personnel are permitted to carry out the work necessary to install, commission and run a device or system.

  • Page 14: Intended Use

    Safety instructions 2.3 Intended use The CMS460-D load current evaluator is designed for the localisation of load currents up to 125 A in TT, TN and IT systems, AC 42…2000 Hz (measuring range see "chapter 8.1 Technical data", paragraph "Measuring circuit"). The CMS system consists of one or several CMS460-D load current evaluators which are able to detect and evaluate load currents in earthed and unearthed power supplies via the associated measuring current transformers.

  • Page 15: System Description

    3. System description In buildings and industrial installations, a fault or failure of the power supply involves high costs. In installations which require a high fault tolerance and good safety, an CMS460 system should constantly monitor the power supply for undercurrent and overcurrent. In addition, the CMS460-D can carry out an harmonics analysis for each channel.
  • Page 16 System description Two response values/common alarm relays, which can be set separately, al- low a distinction to be made between prewarning and alarm. The faulty chan- nel(s) and the associated measured value are indicated on the LC display. If the current falls below or exceeds the release value (response value plus hys- teresis), the release delay t begins.
  • Page 17 System description Connecting measuring current transformers History memory The device utilises a history memory for failsafe storing of up to 300 data records (date, time, channel, event code, measured value), so that all data about an outgoing circuit or an area can be traced back at any time (what hap- pened when).
  • Page 18 System description Analysis of harmonics The harmonic analysis of the measured currents can be selected via the menu item in the CMS460-D. There, the THF and the current value of the harmonics (1…40 at 50/60 Hz, 1…5 at 400 Hz) is displayed numerically and graphically. The total harmonic factor (THF) is expressed as the ratio of the harmonics r.m.s value of an alternating quantity to the r.m.s.
