By increasing the time delay this effect can be avoided.

It detects and indicates residual currents, but does not disconnect. The measurement is done by an external residual current transformer e. g. ND 5016 which is connected via terminals i and k to the IL/SL 5882. At the device IR 5882 the residual current transformer is integrated. All conductors of the voltage system to be monitored are run through the CT except the ground wire. In a fault free voltage system the sum of all current is 0 and the CT induces no secondary voltage. If due to an insulation fault a fault current flows to ground, the current difference in the CT creates a measuring current, which is detected and measured by the IL/SL 5882 or IR 5882. A broken wire in the sensing circuit would disable the measurement, therefore a special circuit detects broken wire and forces the unit to trip. The unit has 2 x 1 changeover contacts. Contact 11-12-14 for alarm (AL) and 21-22-24 for prewarning (VW). Prewarning is detected at 70 % of the selected alarm value. With external bridge X1-X2 the alarm is stored and has to be reset by pressing the reset button or by disconnecting the auxiliary supply. Without bridge X1-X2 the unit works with auto-reset and the fault is not stored. With the button "Test" a fault can be simulated (Alarm). Each contact is delayed with an adjustable time delay tv (same delay time for alarm and pre-warning). To avoid unauthorised adjustment of the potentiometers the unit has a transparent cover that could be seald with laquer. Two holes above the push buttons allow activation of test and reset.

Due to the measurement principle they also detect magnetic fields in the next to the current transformer. When planning a panel with AC/DC sensitive residual current monitors please make sure that no components are placed next to the CT that create a magnetic field, e.g. contactors, transformers etc. If an influence is detected, also a rotation of the CT by 90° could positively reduce the influence. The AC/DC sensitive residual current monitor RN 5883 allows an early detection of insulation faults and detects differential currents with AC as well as DC components in grounded voltage systems (type B). The measurement takes place via an external current transformer. Contrary to an RCD the residual current monitor RN 5883 does not dis- connect the mains when detecting a fault but only indicates it. Besides the easy to read LED chain indicating the actual current several LEDs display operation, pre-alarm and alarm. The 4 measuring ranges cover 10 to 3 A. Additional features are broken wire detection, test function and adjustable pre-alarm. The residual current monitor RN 5883 provides early information for precise and cost effective maintenance before the plant stops.

We reserve the rigth for technical improvements and changes at any time. 2 04.03.20 en / 201A The Measuring circuit includes an external residual current transformer. All conductors of a voltage system are fed through the transformer except the ground wire. In a healthy system the sum of all flowing currents is zero, so that no voltage is induced in the CT. If an earth fault occurs, sourcing a current flowing to ground, the current difference induces a current in the CT that is detected by the RN 5883. If an earth fault occurs, sourcing a current flowing to ground, the current difference induces a current in the CT that is detected by the RP 5883. On broken sensor wires and broken CT coils the unit goes into alarm state and the LEDs for pre-alarm (yellow) and alarm (red) flashes. The unit has 2 changeover output contacts. One for alarm 11, 12, 14 and 21, 22, 24 and one for pre-alarm. 4 Setting Ranges can be slected from 10 mA to 3 A. The fine adjustment is made via potentiometer „Factor“ Measuring range = Range x Factor. The alarm relay switches at 100 % of the adjusted response value. The pre-alarm can be set in 10% steps between 10 and 100% of the alarm value. Potentiometer tv sets the switching delay between 0 and 10 seconds. The delay reacts on pre-alarm and alarm. The different CT sizes require a correct adaption of the residual current monitor. 3 models are available: Type Suitable residual current transformer Frequeny range RN 5883.12/61 ND 5015/024 ND 5015/035 DC + AC up to 250 Hz RN 5883.12/010/61 ND 5015/070 DC + AC up to 180 Hz RN 5883.12/020 ND 5018/105 ND 5018/140 ND 5018/210 DC + AC up to 60 Hz Table 1 An external link on X1-X2 allows the change between energized and de- energized on trip. A change of the function will only be valid after interrup- tion of the supply voltage. Terminal X1 / X2: external link = De-energized on trip, open = Energized on trip De-energized on trip: In the case of groundfault or missing auxiliary supply the relays are de-energized, the NC contacts 11/12; 21/22 are closed In fault free state the relays are energized, the NO contacts 11/14; 21/24 are closed Energized on trip: In the case of groundfault the relays are energized, the NO contacts 11/14; 21/24 are closed in fault free state the relays are de-energized, the NC contacts 11/12; 21/22 are closed If an adjusted value is reached on the measuring input (alarm or pre- warning)at the standard type RN 5883 the signal is stored. Reset is made by pressing the button „Test/Reset“ for < 3 s s or by disconnecting the auxiliary supply (approx. 30 s). If the „Test/Reset“ button is pressed for > 3 s, a test of the unit is made. The time delays run, the pre-warning and alarm is activated. An LED chain shows the fault current between 10 and 100 % of the adju- sted alarm value. An analogue output 0 ... 10 V indicates also the fault current. 10 V corre- sponds to 100 % of the adjusted alarm value. It is of advantage to keep the range small and the Factor high.
