When the red LED blinks, it indicates
that the low set element has picked up.
If the current does not decrease below
the pick-up level the relay will trip.
■
For IDMT curves (SI, VI, EI) the
LED blinks when the current is
greater than 1.2 times the setting
current Is.
■
For the IDMT curve (RI), the LED
blinks when the current is greater
than the setting.

All information concerning earth fault
settings are grouped together in the
lower half of the front panel. Section
numbers below are related to the
numbering on the drawing shown on
page 4.
12. Earth fault pick-up
indicator
When the red LED blinks, It indicates
that the low set element has picked up.
If the current does not decrease below
the pick-up level the relay will trip.
■
For IDMT curves (SI, VI, EI) the
LED blinks when the current is
greater than 1.2 times the setting
current Is.
■
For the IDMT curve (RI), the LED
blinks when the current is greater
than the setting.
■
For the DT curve, the LED blinks
when the l> pick-up setting
is exceeded.
N.B. The LED only blinks when the
phase current is greater than the
minimum operating current (refer to
minimum operating current, page 9)
Also refer to “indicator reset button”
(page 9).
13. Earth fault trip indicator
The indicator is normally black and
turns yellow when the earth fault
element has given a tripping order. It
stays yellow, even when the relay is
de-energised.
14. Setting current Ios
The setting depends on the current
transformer (CT) used, and the range
selected via the connections made to
the back of the relay. The scale label
inserted should match the CT and
range selected. The switch can then be
positioned to the primary amp value
required.
For earth fault relay operation: link
between contacts 2 and 9 (x2 range)
and 1 and 9 (x4 range) must be made
at back of relay.

C.
Indicator reset button
The reset button can be operated with
the sealable cover either open or
closed. When the button is pressed, the
following actions are initiated:
■
It resets the phase overcurrent
and earth fault trip indicators.
N.B.
If reset is more than 48 hours
after the relay has operated and
is left without being energised,
the VAP6 must be used to reset
the trip indicators or the operator
must wait for the relay to be
re-energised.
■
The two red LED’s light up
simultaneously for approximately
three seconds to indicate the
following:
- The relay is energized and the
minimum operating current level
has been reached.
-The relay self testing results are
healthy
N.B.
If one of the two conditions is not
met, the indicators do not light up.
D.
Minimum operating
current
The minimum operating current is the
phase current required for the relay to
be energized and operational. The
setting depends on the CT used, and
the range selected via the connections
made to the back of the relay. The
value given on either side of the scale
label is the single phase RMS
minimum operating current.
N.B. Regarding minimum operating
current:
The VIP 300 does not operate below
the minimum operating current level.
As a result, if the earth fault setting
(Ios) is below the minimum operating
current, it will only take effect when
there is phase current greater than or
equal to the minimum operating
current.
E.
VAP6 test plug
The test plug is exclusively designed for
connection of the VAP6 which is used
for fast, simplified relay testing.
The operation may be carried out while
the relay is operating since the VAP6
and VIP 300 provide the possibility of
testing with inhibition of circuit breaker
tripping.
Also refer to the “testing and
commissioning” chapter.
This function may be used to
carry out a basic relay operation test.

simplified testing.
The test can be carried out in the
following two cases:
- the VIP 300 is already
powered up by the sensors
(CT’s).

4■
Trip inhibition:
By pressing and holding this
button down the relay can be
tested with the VAP6 without
tripping the circuit breaker. This
facility will inhibit the circuit
breaker tripping even if a real
fault occurs during the test.
A ■ On:
Indicates that the batteries are
operating. Also lights up when the
battery test is carried out by
pressing “battery test”.
B ■ Test in progress:
Confirms sending of the test
stimulus to the VIP 300.
D ■ “External MITOP” output:
This feature may be used to
connect an external MITOP trip
coil which could be used to
operate a timer etc. The external
coil is triggered at the same time
as the circuit breaker MITOP. The
trip inhibit button does not effect
the external coil.
Batteries:
■
The batteries are normally
deactivated and are automatically
activated when the VAP6 is
connected to the VIP 300. They
are activated in the following
cases:
- Pressing the “battery test”
button.
- Direct connection to a VIP 300
relay.
■
To install or change the batteries,
open the unit by removing the 4
screws on the bottom of the unit.
Be sure to use the correct
polarities.

VIP 300
VAP6 test sequence
The test may be carried out with or
without the relay energised by the
Ringmaster current transformers, and
all the relay settings are effective.
During the test, the relay remains
operational and will give a tripping
order in the event of a fault, unless the
“trip inhibit” button is pressed and held
down.
The test consists of:
- Initiation of the VIP 300 self
monitoring and diagnostic routine.
- Injecting a stimulus to stimulate
a phase fault.
- Check tripping
The VAP6 is supplied by
batteries. Therefore the parts of
the VIP 300 that run on AC
current are not checked using this
method (input and supply
circuits).
Press the “phase overcurrent” button to
send the test stimulus.
- Continue pressing the button
throughout the duration of the
stimulus. The stimulus represents
about 20 times the setting current
Is.
-The VAP6 “test in progress”
indicator lights up to confirm the
sending of the stimulus to the
VIP300 relay.
- The red “I>” indicator of the
VIP300 blinks during the time
relay delay period.
- Then the VIP 300 phase “trip”
indicator turns yellow.
- The circuit breaker trips if it is
not inhibited.
Connect the VAP6 to the “VAP6 test
plug”. The VAP6 batteries are activated
and the “on” indicator lights up.
Press the “trip inhibition” button if the
test should be carried out without
tripping the circuit breaker.
Be sure to continue pressing the
“trip inhibition” button throughout the
time it takes to send the stimulus.
N.B. If the “phase overcurrent” button is
held down after tripping, the VIP300
starts the time delay/tripping cycle
again; this is normal operation.
In that case:
- The VAP6 red “trip” indicator
lights up for a transient period
each time there is a trip.
- Depending on the time delay
setting, the VIP 300 red “I>”
indicator may be off or blink
rapidly and/or in an irregular
manner.
Press “earth fault” to test the relays
operation. The stimulus injected is equal
to 20 times the setting current Ios. Use
the procedure as for the phase
overcurrent test.
Disconnect the VAP6. In order to save
batteries, do not leave the VAP6
connected to the relay unnecessarily.

Commissioning Ringmaster with VIP 300
Factory tests:
Reduced commissioning:
Secondary injection:
All Ringmaster panel types are fully
tested before leaving the factory. These
tests include the whole protection
system including current transformers,
wiring harness, relay, trip coil and the
circuit breaker itself using primary
injection to energise the system.
Tripping tests are carried out using
different settings for each of the IDMT
and DT curves available on the relay.
The tripping times are measured with a
chronometer and its accuracy is verified
against the theoretical times calculated.
Since the system is fully tested it is only
necessary to prove the relay on site at
the service settings, therefore reducing
commissioning time to a minimum.
Once the switchgear has been installed
and cabled up, it is impractical or
sometimes impossible to carry out
injection tests. It is suggested that for
commissioning and maintenance
purposes either of the following two
methods can be used.
1.
Simple trip test using the VAP6
test unit (described previously).
2.
Secondary injection using
standard equipment with an
output filter.
Testing using secondary injection is
used to test the following parts of the
protection system:
■
The electronic circuit.
■
The integrity of the power supply
of the VIP 300.
■
The link to the mitop trip coil and
also the circuit breaker
mechanical tripping mechanism.
■
The integrity of the switches on
the front panel to ensure they
give the correct tripping times for
the curves selected.
Test set connections:
Caution:
The injection set is connected to the VIP 300 relay without disconnecting the CT’s.
This is done via the sockets on the terminal rail located in the pilot cable box, just
above the relay itself.
■
Phase overcurrent connections:
■
To test the overcurrent protection the connection should be made across two CT’s
(terminal rails no’s 4 to 5, 5 to 6 or 6 to 4).
Earth fault connections:
To test the earth fault protection, the connection should be made across one CT
(terminal rail no’s 4 to 7, 5 to 7, or 6 to 7).
These terminal numbers should be cross checked with the relevant circuit breaker
schematic diagram. Terminals 15 and 16 (not shown above - see Ringmaster
selection guide) give access to a normally open contact, which is normally open
when the CB is in the open position. This can be used to connect a timing device to
measure the opening time of the relay and circuit breaker.
The type of test plug used to connect to the DIN rail connectors is a standard 2mm
19A test plug.
■
■
Note: When using a secondary injection set with VIP 300 a filter (e.g. Foster SF30)
should be used to improve the wave form. If a filter is not used the operating time of
the relay may not follow the theoretical operating times.

carried out without disconnecting
the MITOP trip coil or VIP relay.
Secondary injection facilities are
provided on the terminal rail in the

No external connections should
be made to the VIP 300 or the

VIP 300
Commissioning Ringmaster with VIP 300
Recommended test
procedure for
secondary injection:
The test procedure outlined here is only
a guide and may need modifying to suit
the different test sets available.
1.
Pick-up check
- Increase the current slowly until
the appropriate LED indicator
starts to blink.
2.
Setting check:
- Set the current to be injected
(a true RMS ammeter should be
used to measure the current).
- The CB should then be closed
and the counter/timer reset. The
current should then be applied.
- When the CB has operated, the
applied current should be turned
off if not done automatically.
- The time shown on the counter
display includes the operating
time of the circuit breaker
>80ms or <100ms. The actual
relay operating time can then be
calculated by subtracting this
time from the counter reading.
The manufacturers instructions should
be read before attempting to secondary
inject the VIP 300 relay.
The VIP 300 relay can be secondary
injected like any conventional 1A relay,
therefore the output recommended for
1A relays should be used.
Calculate the secondary current to be
injected from the equivalent primary
current, taking into account the CT’s
used and the range selected by
connections to the terminals on the
back of the relay.
With the VIP 300 connected so as to
present the correct burden, the following
tests can be carried out:
Note. - No connection should be made to the MITOP trip coil from the secondary
injection test set.
