RCMS460-490_D00067_03_M_XXEN/12.2017

Safety instructions

2.3 Intended use

The RCMS460 or RCMS490 residual current monitor is designed for measuring residual and operating currents TT and TN-S systems (measuring range see "Chapter 8.3 Technical data", paragraph "measuring circuit"). Alternatively, digital inputs can be scanned and evaluated. The RCMS system consi sts of one or m ore RCMS460- D/-L or RCMS490-D/-L residual current monitors, which are able to detect and evaluate fault, residual and operating currents in earthed power supplies via the related measuring current transformers. The maximum voltage of the system to be monitored depends on the nominal insulation voltage of the measuring current transformer used in the case of busbar systems, resp. depend on the cables or conductors that are routed through.

To measure AC/DC sensitive residual currents (according to IEC/TR 60755: Type B) closed W…AB series measuring current transformers are required. Six W…AB series measuring current transformers require one AN420 or AN110 power supply unit. For alternating and pulsating currents (according to IEC/TR 60755: Type A W… (closed), WR… (rectangular), WS… (split-core) and WF… (flexible) series measuring current transformers are used.

Any combination of the various measuring current transformer series can be connected to the evaluator measuring channels. Each RCMS460-D/-L and RCMS490-D/-L has 12 measuring channels. Up to 90 residual current monitors can be connected via a BMS bus (RS-485 interface with BMS protocol), thereby up to 1080 measuring channels (sub-circuits) can be monitored. If this product is used for personnel protection, fire or plant protection, the frequency response can be set accordingly. The measured currents can be analysed for harmonics. The THF can be determined too (THF =

otal Harmonic Factor).

The product must be adapted to local equipment and operating conditions by making individual parameter settings, in order to meet the requirements of applicable standards and to attain the protection goals.

RCMS460-490_D00067_03_M_XXEN/12.2017

Safety instructions

In order to meet the requirements of the applicable stan dards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the range of application indicated in the technical data.

Any use other than that described in this manual is regarded as improper.

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 RCMS system should constantly monitor the TN-S system for insulation deterioration to ensure that the system is "clean" and electromagnetically compatible.

3.1 Typical applications

 Measuring and evaluating residual, fault and rated currents of loads

and installations in the frequency range of 0…2000 Hz (W…, WR…,

WS…, WF… series measuring current transformers, 42…2000 Hz (W…,

WR…, WS…, WF… series measuring current transformers) (measuring

range see "Chapter 8.3 Technical data").

 Monitoring of currents which can cause fires in flammable atmos-

pheres.

 EMC monitoring of TN-S systems for "stray currents" and additional N-

PE connections.

 Monitoring of N conductors for overload caused by harmonics  Monitoring of PE and equipotentional bonding conductors to ensure

they are free of current.

 Residual current monitoring of stationary electrical equipment and sys-

tems to determine test intervals which meet practical requirements in

compliance with the accident prevention regulations BGV A3 (Ger-

many).

 Personnel protection and protection against fire by rapid disconnec-

tion.

 Monitoring of digital inputs.

System description

3.2 Description of function

The currents are detected and evaluated as true r.m.s. value s in the fr equenc y range of 0 (42)…2000 Hz. All channels are scanned simultaneously so that the maximum scanning time for all channels is ≤180 ms if 1 x the response value is exceeded and ≤ 30 ms if 5 x the response value is exceeded. The latest current values of all channels are shown on the LC display in bar graph format. If one of the two set response values is exceeded, the response delay t

begins. Once the response delay has elapsed, the common alarm re-

lays "K1/K2" switch and the alarm LEDs 1/2 light up. Two response values/common alarm relays, which can be set separately, allow a distinction to be made between prewarning and alarm. The faulty channel(s) and the associated measured value are indicated on the LC display. If the current falls below the release value (response value plus hysteresis), the release delay "toff“ t mon alarm relays switch back to their initial state. If the fault memory is enabled, the common alarm relays remain in the alarm state until the reset button is pressed or a reset command is sent via the BMS bus. The device function can be tested using the test button. Parameters are assigned to the device via the LC display and the control buttons on the front panel of one of the connected RCMS…-D devices or via connected panels, Ethernet gateways (z. B. COM460IP) and Condition Monitors (z. B. COMTRAXX CP700). With the adjustable preset function the response values can set for all channels taking the latest measured value for each channel into account.

Digital input

Each individual channel can be used for one of the following monitoring functions:

– As digital input using a potential-free contact 1/0 – Or for current or residual current monitoring in combination with

measuring current transformers.

System description

History memory in RCMS460-D, RCMS490-D

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 happened when).

Analysis of harmonics

The analysis of the harmonics of the measured currents can be selected via a menu item in RCMS460-D, RCMS490-D. There, the DC component, 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.

3.3 Device variants

RCMS residual current monitoring systems differ depending on the residual current monitor version used, RCMS460… or RCMS490….

RCMS460-D

Device version RCMS460-D utilises a backlit graphical display. This version is used for local display of detailed information about all devices connected to the bus in the control cabinet. This device can be used to parameterise all RCMS devices connected to the BMS bus and to display all measurement details. Several RCMS-D devices can be used within one system.

RCMS460-L

Device version RCMS460-L utilises a two-digit 7-segment display where the address of this device is displayed within the BMS bus. The alarm LEDs indicate in which measuring channel the response value has been exceeded. Parameters can be set via an RCMS…D, an tion Monitor (z. B. COMTRAXX CP700).

Ethernet gateway (z. B. COM460IP) or a Condi-

RCMS490-D/RCMS490-L

The function of the device versions RCMS490-D/RCMS490-L corresponds to the function described above. In addition, a galvanically isolated alarm contact (N/O contact) is available, e.g. for triggering a circuit breaker in this subcircuit when a response value is exceeded.

RCMS460-490_D00067_03_M_XXEN/12.2017

System description

RCMS…-D4/RCMS…-L4

The function of device version RCMS…-D4/RCMS…-L4 corresponds to the function described before. The functions of measuring channels k9 … k12 vary from those described before. They are exclusively designed for current measurements with type A measuring current transformers (measuring range 100 mA … 125 A). For that reason, the measuring channels k9…k12 cannot be used in c ombi nat ion w ith W…AB ser ies measuring current transformers or as digital inputs.

6.6.4 Menu 4: Harmonics

The analysis of the harmonics of the measured currents is displayed as a bar and a current value. Harmonics are multiples of the rated frequency. Example: Rated frequency = 50 Hz, 2nd Harmonics = 100 Hz. The RCMS…-D… can only determine the harmonics currents correctly if the selected rated frequency in menu "6. Settings-> General-> Rated frequ." suits the current being monitored.

At 50 o r 60 Hz, the cur ren t v alu e of harmonics 1…40 is displayed; at 400 Hz the current value of harmonics 1…5 is displayed.

THF: The total harmonic factor (THF) specifies the ratio of the har-

monics r.m.s value of an alternating quantity to the fundamental r.m.s. value. The smaller the THF, the more sinusoidal the current signal.

If 50 or 60 Hz are selected in the "Cut-off frequency" menu (see page 65) the THF cannot be determined. The display indicates „- - -“ .

An analysis of the harmonics cannot be carried out in disabled channels or channels with digital input. The display indicates „- - -“ .

Operation

If the measuring channel settings only differ slightly, we recommend to proceed as follows:

- first set all the measuring channels (1…12) to the same value

- then modify the setting of an individual measuring channel.

2. Response value

The response value is the value at which an alarm is output. In case of digital inputs, set the status (0 or 1) at which an alarm is to be signalled.

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/12.2017
