Indication Definition
Voltage present
Threshold values for voltage presence indication:
0.1 - 0.45 x Service Voltage.
INSTALLATION NOTE: the voltage signal is too low when
operating the system at nominal voltage.
The causes are usually:
- a wrong ordered service voltage or,
- the operation of the switchgear at a nominal voltage which is
lower than the one for which the device was originally rated.
Voltage present and integrated maintenance test passed
The current flowing through the indication device complies
with the requirements for current monitoring according to
IEC 61243-5 (VDE 0682 Part 415), Section 5.28
(maintenance test on the integrated VDS).
A maintenance test is not necessary due to the continuous
monitoring and indication.
Voltage present and integrated maintenance test
passed, however the voltage signal is too high
INSTALLATION NOTE: Voltage signal too high.
The cause is usually:
- a wrong ordered service voltage or,
- the operation of the switchgear at a nominal voltage which is
higher than the one for which the device was originally rated.
Voltage not present
All symbols are in off-state while the switchgear is
de-energized. Presence of voltage <0.1 x Service Voltage.

Functional test
A functional test is possible while the unit is energized (indication of arrow and dot
symbols) or while the unit is de-energized.

Energized state
Perform the functional test by short-circuiting one of the three test sockets with the
earth socket. The displayed symbol (L1, L2 or L3) disappears. The short-circuit jumper
must be removed after the test.
De-energized state
There are two possibilities to perform the functional test in the de-energized state:
1: Display test
b Press the ‘Display’ button.
b All symbols on the LCD indication are activated momentarily.
2: Functional test using the "function tester for Wega".
b Connect the measuring leads of the function tester to one of the three test sockets

Precautions
VIP installed in a cubicle
bb Transport
VIP relays can be transported by all suitable means of transport in the usual conditions
for cubicles.
Storage conditions should be taken into consideration for a long period of transport.
bb Handling
If the cubicle is dropped, check the VIP’s condition by visual inspection and energising.
bb Storage
Schneider Electric recommends keeping the cubicle protective packaging for as long
as possible.
VIP relays, like all electronic units, must not be stored in a damp environment for more
than one month. They should be energized as quickly as possible. If this is not
possible, the cubicle reheating system must be activated.
Phase Current Sensors
VIPs operate exclusively with dual core CUa (200 A primary) and CUb (630 A primary)
current sensors.
These sensors provide:
bb the VIP power supply,
bb metering of all 3 phase currents and the earth fault current.

The use of dedicated sensors means that the complete protection chain performance
(sensor, VIP, Mitop trip unit) can be guaranteed.
It is very easy to connect VIP relays to the CUa or CUb sensors by means of 2
prewired connectors from the sensors:
bb 1 x 9-pin SUBD connector for metering the phase and earth fault currents,
bb 1 x 6-pin lockable connector for the VIP power supply.

The CUa and CUb current sensors consist of 2 windings per phase:
bb one winding providing the VIP power supply,
bb the other winding enabling the VIP to measure the phase currents.
The earth fault current is measured by taking the sum of the 3 phase currents inside
the sensor.

Instructions for putting into operation the protection relay for circuit- breaker RM6 - Instructions for use

After a trip, the fault indication LEDs are powered by the battery embedded in the VIP
or by the VIP410 auxiliary power supply.
Fault indication by the LEDs can be stopped:
bb by pressing the Reset key,
bb automatically by the reappearance of a current in the network higher than the
pick-up current,
bb automatically after 24 hours,
bb by remote control order via the communication (VIP410).

For the first 3 LEDs, faster flashing may occur before the protection trips, to indicate
the following information:

pictogram overshoot
Overshoot of the instantaneous set point for phase
overcurrent protection (I> or I>> or I>>> pickup outputs)
Overshoot of the instantaneous set point for earth fault
protection (Io> or Io>> pick-up outputs)
Overshoot of the alarm set point for thermal overload
protection

Note

In custom mode, the protection set points may not be assigned to the Mitop trip unit
output. In this case, the fault indication LED may be active, without being
associated with the circuit-breaker trip. Depending on the application, this
can indicate the presence of a fault without tripping the circuit-breaker. The fault
indication LED pictograms can be customized by sticking a label to the right of the
LEDs.

Display
Io The display is an LCD unit.
It is only back-lit on the VIP410, when the auxiliary power supply is present.

Default Screen
A default screen is displayed automatically 3 minutes after the last keystroke.
This default screen is the screen displaying the phase currents.

Operation according to the Power Supply Mode (VIP400)

The VIP400 is a stand-alone protection relay powered by its current
sensors. When current is present in the medium-voltage (MV) network, the protections
and the display work and it is possible to enter settings and view measurements.
The current in the MV network on which the VIP operates is called the ’pick-up current’.
When no current is flowing through the circuit-breaker (for example circuit
breaker open), or when the current in the MV network is too low, the VIP is off and
nothing appears on its display. If current appears, the protection functions are
activated and trip the circuit-breaker ‒ or not ‒ according to their settings.
The additional time taken by the VIP to start when current appears is called
the "pick-up time". More information on the value of the pick-up current and the pickup
time are available in the VIP Function Characteristics. Consult the reference
NRJED311207EN.

Operation according to the Power Supply Mode (VIP410)

The VIP410 is a relay with a dual power supply. It is powered both autonomously by its
sensors and by the auxiliary power supply. Like for the VIP400, the self-powered
supply allows the protection functions to work even if the auxiliary power supply fails.
The auxiliary power supply is used to power functions that do not depend on the
current being present in the MV network. These functions are marked in the
function table (consult the reference NRJED311207EN). The auxiliary power supply
must be present in order them to work.

Integral Battery
The VIP has an integral battery. It is used to:
bb activate the user-machine interface in order to enter settings when the VIP is not
supplied with power.
bb illuminate the fault indication LEDs when the VIP is no longer supplied with power
after giving the opening order to the circuit-breaker.
bb power the internal calendar.
When the VIP is not supplied with power:
Pressing and holding down the key activates battery-powered operation of the
user-machine interface. It is then possible to access the menus in order to enter
settings. In this case, the display turns off automatically after 3 minutes of inactivity on
the keypad.
bb The protection functions are activated automatically if the current reappears. The
integral battery plays no part in operating the protection functions. The protection
functions work even when there is no battery.

NOTE:
bb in battery operation mode, the VIP processor runs with a reduced clock frequency to
ensure the battery life is maintained. As a result, the user-machine interface may be
slower to react.
bb during a setting operation with the VIP powered by its internal battery alone, the
clock display is not refreshed on screen. However the internal clock increments
normally.

Frequency
The network frequency (50 Hz or 60 Hz) is a parameter that must be known for
operation of the VIP40 and VIP45 signal processing algorithms.They therefore have
an automatic frequency recognition system.
The recognized value (50 Hz or 60 Hz) is stored and the VIP works permanently with
this value.
This stored value is used each time the VIP starts.
For the VIP to recognize the network frequency and store it, it has to detect a current
on phase 1 for a minimum period of 5 seconds in the range 50 Hz +/- 2 Hz or
60 Hz +/- 2 Hz.
This detection happens when the VIP starts.

LV Connection Indicator Flair 2xD

NOTE: The Flair 2xD fault passage indicator does not apply to the RM6 Connected
Advanced unit.

The Flair 21D, 22D and 23DM fault passage indicator is self-powered by the
measurement sensors. A minimum 2 A current is required in the MV cable to start up
the Flair 21D display, an energy storage guarantees a 4-hour minimum autonomy.
The Flair devices have an output contact for interfacing with a SCADA system.
Flair 22D/23DM can be connected to a voltage presence indicating system (VPIS)
provided with a voltage output (VPIS-VO). In this case, for greater reliability, fault
detection is confirmed by voltage absence without taking into account the current.
Flair 23DM has to be supplied from 24 Vdc to 48 Vdc for a permanent display operating
and for the outdoor lamp supply (with a single zero sequence CT, self powering is
not possible).

SOLVENTS AND ALCOHOL FORBIDDEN

HIGH-PRESSURE CLEANER FORBIDDEN

Panelling
Schneider Electric draws your attention to the risk of using high-pressure cleaning
processes.
Schneider Electric cannot therefore guarantee the reliability of equipment that has
been cleaned in this manner, even if cleaning has been followed by lubrication.
The main drawbacks of this process are:
b deterioration due to jet pressure and impossibility of relubricating the inaccessible
fixing points.
b risk of overheating due to presence of solvent on the contact zones.
b elimination of special protections.

Earthing Covers
This operation can be performed in event of excessive soiling.
Clean using a sponge and clear water. Do not use alcohol or other solvents to clean.

Maintenance Cycle and Operations

This device is designed to operate for 30 years or for 1000 operations in normal
conditions of use as per standard IEC 62271-1.
The following are recommended:
b an O/C operation every 6 years for motorized functional units and/or functional units
with a latching mechanism (Q and D/B function);
b replacement of batteries is recommended every 4 years;
b inspection every 5 years of the condition of the mechanisms (pollution, corrosion)
and the cleanliness of the earthing covers (pollution).
