The device is supplied with DC auxiliary voltage via terminals A1(+) / A2.
Switching on the auxiliary voltage (Power-On) is followed by an internal
self-test for 12 s (see „Device test functions“). The test process is visible
with the status LED. After this, measurement of the insulation resistance
in the measuring circuits begins and the status LED changes into green.
Measuring circuit
(Insulation measurement between terminals L1(+) / L2(-) on the
coupling device and PE1/PE2 on the insulation monitor)
The insulation monitor RN 5897/320 can only be used with a coupling
device. Max. mains voltage and connection diagrams have to be observed!
To connect the insulation Monitor RN5897/320 to a coupling device the
terminals with identical designations are connected (VSG1, VSG2, L(+),
L(-)) .The votage system to be monitored is connected to L1(+) und L2(-)
of the coupling device.
A broken wire detection that can be disabled provides a fault signal if
both terminals L1(+) and L2(-) are not linked by the connected network.
Broken wire between coupling device and insulation monitor cannot be
directly detected but the the measured value of the insulation resistance
when one or more connections are interrupted, is much lower then the real
insulation value which will cause a tripping of the alarm relays.
The type of the voltage system or the connection method (AC, DC, 3NAC)
has to be correctly adjusted on the rotational switch "UN"
Also the terminals PE1 and PE2 have to be connected with 2 separate
wires to the protective earth. An interruption of a wire also causes a fault
signal (see section ”Behavior on faulty connection”). The monitoring of
the PE connection cannot be de-activated.
To measure the insulation resistance an active measuring voltage with
changing polarity is connected between L1(+) and L2(-) and PE1/PE2.
The duration of the positive and negative measuring phase depends on
the actual leakage capacity of the monitored system and in DC systems
also on the level and duration of possible voltage variations. This allows
a correct and fast measurement in different network conditions.
At the end of a measuring cycle the actual insulation resistance is produced
and indicated. The relays for alarm K1 and pre-alarm K2 switch when
dropping under the adjusted response values. In addition the status LED
changes to orange color on pre-alarm or to red color on alarm.
Manual reset of fault message
With the 2-section rotational switch "UN", manual or auto reset of the alarm
can be selected. If manual reset is activated the insulation fault signals
of the measuring circuit are stored when dropping under the adjusted
response values also if the insulation resistance goes back to healthy
state. Pressing the „Reset“ button on the front side for 2 s, the alarm signal
is reset if the actual insulation resistance is in healthy state.
Indicator relay for insulation fault signal
The function of the relays K1 (contacts 11-12-14 for alarm) and K2 (contacts
21-22-24) can be altered between energised on trip (relay n.o.) or de-
energized on trip (relay n.c.). When energised on trip the relays energize
when the value drops below the setting, when de-energised on trip, the
relays de-energize when the value drops below the setting.
Disable the measuring function
Using the external control input X1/X2 the measuring function of the
RN 5897/320 can be disabled. This could be used when several isolated
voltage systems with individual insulation monitors need to be coupled.
The measuring voltage is set to -90V (negative measuring phase) and
the evaluation of the measurement is stopped. The status of the output
relays is frozen and not changed any more. If the measurement is disabled
the status LED flashes continuously orange. Please be aware, only the
evaluation of the measurement is stopped and the measuring pulse is
interrupted! A high resistive disconnection to PE does not take place
(see internal resistance).
Broken wire detection
As described in section "Measuring circut", the measuring circuits L(1+)/
L2(-) and the protective conductors PE1/PE2 are constantly monitored for
wire breaks – not only at Power-On or a manual or occasional automatic
test. The response time of PE1/PE2 monitoring is only a few seconds.
The response time of monitoring of L1(+)/L2(-) can be up to approx.
2 min. Broken wire detection between L1(+) and L2(-) is performed via
coupled alternating voltage. This alternating voltage is short-circuited if
the terminals are connected to the connected mains at low-resistance.
The device detects that the mains to be monitored is properly connected.
Since this broken wire detection is carried out with alternating voltage, large
capacitances should be avoided between L1(+) and L2(-), since the
capacitive reactance of these capacitances also short-circuits this
alternating voltage. The device would no longer detect a connection fault
on L1(+)/L2(-).
Especially parallel lines should be prevented over larger distances.
If larger capacitances between L1(+)/L2(-) cannot be avoided or if the coupled
alternating voltage interferes with the system, the broken wire detection
can be de-activated on the 2-section rotational switch for alarm "RA". It
can be altered between continuously disabled (Broken Wire Detect OFF),
or continuously enabled (Broken Wire Detect ON) for 10 seconds every
2 minutes. If the broken wire detection on L1(+)/L2(-) is de-activated no
AC voltage is injected. The broken wire detection on PE1/PE2 cannot be
de-activated.
Device test functions
Principally, 2 different test functions are implemented: The "self-test" and
the "expanded test":
The self-test of the device is performed automatically after Power-On and
every full operating hours. It can also be triggered manually at any time by
pressing the "Test" button at the device front for 2 s.
With the self-test, contrary to the expanded test, the status of the Indicator
relays is not affected; the sequence is as follows:
The self test is indicated by the status LED with flash code 1 in orange colour.
First the negative measuring pules is activated for about 5 s and the internal
measuring circuit is checked on failures. Then the positive measuring pulse
is activated for about 5 s and more internal tests are performed. If no failures
are detected, the normal measurement continuous. The extended test is
started, when during or at the end of above procedure (12 s) the button
"Test" is pressed again for 2 s.
The procedure is the same as above (2 measuring phases with 5 sec
each) but in addition the output relays K1 and K2 go into alarm state. The
Status LED shows flash code 2 in orange colour. The test phases will be
continuously repeated. The extended test can be finished after the first
complete sequence (approx. 10 sec) by pressing the "reset" button for 2
seconds. The device starts the insulation monitoring again.

Behaviour with internal device faults
If internal device faults were detected during the test function, the status
LED flashes permanently red. The indicator relays K1 and K2 switch to
the alarm state.
Behavior on faulty connection
When detecting broken wire on terminals L1(+)/L2(-), the measurement
is disabled. The reaction time could be up to 2 min. The monitoring relays
K1 and K2 go in alarm state, the status LED shows flash code 1 in red
colour. After removing the interruption the fault is automatically reset
(max. reaction time up to 2 min) and the measurement of the insulation
resistance is continued. Stored alarm values remain stored. An interruption
of the protective earth connections PE1/PE2 causes the same reaction
as interrupting the measuring circuit, only the status LED shows flash
code 2 in red colour.
External control input
To terminals X1/X2 an external combined Test-/Reset button can be
connected. If the terminals X1/X2 are bridged for approx. > 1,5 s and <
10 s the test mode is started. This has the same function as pressing the
internal test button. When bridging X1/X2 for < 1,5 s , a stored alarm will
be reset. This has the same function as pressing the internal reset button.
If X1/X2 is activated for > 10 s, the measuring function is stopped.
The measuring function remains suspended for the duration of the control
of X1/X2.
Programming/setting of parameters/set-up of the insulation monitor
All settings are made via 3 rotational switches on the front of the device.
To avoid unauthorised manipulation of the settings, the unit has a sealable
transparent cover on the front.
With the first rotational switch "R
A
" the response value for Alarm is selected.
In addition the rotational switch has 2 sections. If the rotational switch is in the
first section the broken wire detection of the measuring circuit is continuously
on. If the rotational switch is in the second section it is continuously off. The
second rotational switch "R
pA
" has also 2 sections and selects the pre alarm
value as well as the output function. in section 1 the unit is de-energised on
trip (n.c.) in section 2 on energised on trip (n.o.).
The third rotational switch selects "UN" selects the voltage system connection
and manual or auto reset it has also 2 sections. In section one the unit is on
auto reset, in section 2 it is on manual reset. Changes of the setting the unit
accepts immediately without restart.

Notes
WARNING
Risk of electrocution!
Danger to life or risk of serious injuries.
• Disconnect the system and device from the power supply and ensure
they remain disconnected during electrical installation.
• Determine voltage free status by using appropriate instruments
• The terminals of the control input X1-X2 have no galvanic separation
to the measuring circuit L1(+) and L2(-) and are electrically connected
together, therefore they have to be controlled by volt free contacts or
bridge. These contacts ore bridges must provide a sufficient separation
depending on the mains voltage on L1(+)-L2(-).
• Please do not connect external voltage to terminals X1/X2. The control
must only be made by bridging X1 and X2.
• The coupling unit RL 5898 or RP 5898 must only be used in conjunction
with the RP5897/320 on a voltage system and not just by itself.
!
Attention!
• Before checking insulation and voltage, disconnect the monitoring device
RN 5897/320 from the power source!
• In one voltage system only one insulation monitor can be used.This has
to be observed when interconnecting two separate systems..
• Device terminals PE1 and PE2 must always be connected via separate
lines to different terminal points of the protective-conductor system.
• The device must not be operated without PE1/PE2 connection!
nfo
Attention!
• The main measuring circuit can be connected with its terminals L1(+) and
L2(-) both to the DC and also AC side of a mixed network; it is done most
practically where the primary incoming power supply takes place e.g.
with battery networks with connected inverters on the DC side, with
Generators/Transformers with connected Rectifiers or inverters on
the AC-side. To monitor a 3NAC system the device can be connected
single pole, (L(+) and L(-) are bridged, to the neutral of the 3p4w sy-
stem. The 3 phases have a low-Ωic (approx. 3 – 5 Ω) connection via
the transformer windings so also insulation failures of the not directly
connected phases are detected. Via the rotary switch "UN" the correct
type of network needs to be selected (see „Connection Examples“).
• If a monitored AC system includes galvanically connected DC circuits
(e.g. via a rectifier), an insulation failure on the DC side can only be
detected correctly, when a current of min 10 mA can flow via the semi-
conductor connections.
• If a monitored DC system includes galvanically connected AC circuits
(e.g. via an inverter), an insulation failure on the AC side can only be
detected correctly, when a current of min 10 mA can flow via the semi-
conductor connections.
• The insulation monitor RN 5897/320 can only be used together with
a coupling device.
