1. General
This manual describes the general functions of the arc
protection unit, it also includes mounting and configuration
instructions.

1.2. Unit features
VAMP 120 is a state of the art arc protection unit for electrical
po er distribution systems.
By using VAMP 120 in s itchgears considerable safety
improvements are obtained in the form of minimized injury and
damage in case of an arc fault.
VAMP 120 is a “stand alone” system, hich gives a compact
solution hen the application doesn’t require overcurrent
measurement or hen the overcurrent information is available
from the incomer protection relay or any other arc protection
unit (VAMP 221 / VAM 4C). It is possible to connect 4 arc
sensors, of the type VA 1 DA or VA 1 EH, to the VAMP 120
unit.

2. Unit configuration
Figure 2-1. VAMP 120 dips itch operations and sensor connection
The unit is configured using the dips itches:
Dipswitches 1-5 (see igure 2-1):
If only one arc sensor in use, SENSOR 1 input should be used.
•
SW nr. 1 : if sensor input 2 is also required, SEN 1
should be set to the left position.
•
SW nr. 2 and 3 :
if sensor input 3 and 4 are used, SW nr. 2
and 3 should respectively be set to left
position.
•
SW nr. 4 : is setting the system selectivity. If set to
the left position, sensor nr. 1 and 2 ill
trip relay T1. Accordingly sensor nr. 3 and
4 ill trip relay T2. The NC trip signal
out put ill al ays ork in parallel ith
T1. If SW nr. 4 is to the right, all four
sensor channels ill activate both trip
groups.
•
SW nr. 5 : is the selection of tripping criteria. If set
to the right, the unit ill trip for light
only. If set to the left, the unit needs both
light and current information for tripping.
•
SW nr. 6 and 7 :
the Latch s itches enables latching of the
trip relays. When it is in ON position the
latching function is activated.
•
SW nr. 8 : is the configuration s itch for sensor
inputs 2 and 3. If it is in “ON” position,
sensor 2 or 3 activation ill make a
common trip of both T1 and T2. If it is in
“OFF” position, sensor 2 is linked to T1
and sensor 3 to T2.

3. Sensors
3.1. Arc sensor VA 1 DA
The arc sensor is a light sensitive element, hich is activated
by strong light. Arc sensors should be mounted in the s itch-
gear cubicles, in such a ay that the light sensitive part (see
Figure 3.1-2) covers the protected area as completely as
possible.

Figure 3.1-2. The sensitivity of the VA1DA arc sensor to light from different
directions.
In open spaces, such as the bus bar section, arc sensors should
be mounted max. four meters apart.
The light sensitivity of the arc sensor is 8000 LUX
The arc sensor can be mounted from the outside on partition
all of the s itchgear. The active part of the sensor is mounted
in a 10 mm hole, to the area in the s itchgear that should be
protected, and fastened ith a 4 mm self-tapping scre (see
Figure 3.1-3).

The arc sensor can alternatively be mounted completely in the
protected area ith the help of a mounting plate VYX 01 (Z-
shaped) or VYX 02 (L-shaped). (See Figure 8.3-1)

4. unctions
VAMP 120 includes an extensive self-supervision. The self-
supervision includes internal functions as ell as all arc
sensors.
Figure 4-1. Self-supervision block diagram
If an internal fault occurs the self-supervision relay is activated
and the ERROR-led is lit.

5. Applications
Every compartment is equipped ith an arc sensor. Up to four
sensors can be connected to the VAMP 120 unit. The trip relays
are electromechanical and can be connected directly to control
the circuit-breakers (see chapter Technical data).
The VAMP 120 is suitable for small po er generation plants
here light is the only criteria for tripping and full selectivity
is required.

6. Connections
*Connection for shield if shield sensor cable used (VA1DA-20s)
Figure 6-1. VAMP 120 connection
The VAMP 120 unit comprises t o independent arc protection
zones. Both zones have their o n trip relay, trip 1 and trip 2.
Trip 1 is controlled by sensor inputs 1 and 2. Trip is controlled
by sensors 3 and 4.
Trip alarm is activated if either or both are tripping. If “T1=T2”
dip s itch is at “on” position, both trip outputs ill ork in
parallel for any sensor activation.
If “S1=S2” dip s itch is at “on” position, sensors 2 and 3
activation ill cause both T1 and T2 to trip. This is e.g. used for
CB compartment supervision here t o zones are overlapping
each other.
