The devices measure AC and DC current (AC / DC sensitive. 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.

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 tvsets 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:

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.
Example: Setting 300 mA: Range 0,1 x Factor 3 = 300 mA

High forces when mounting may damage the current transformer fixtures.
The fixing clips are designed to support the current transformer. Forces
that are applied by the cable running through the current transformer can
only be tolerated within limitations.
During installation and afterwards please make sure that the wires are
led through the current transformer without applying pressure and remain
stable in that position.
