Page 4: General
VAMP 121(D) is a “stand alone” system, which gives a compact solution when the application doesn’t require overcurrent measurement. It is possible to connect 10 arc sensors, of the type VA 1 DA, to the VAMP 121(D) unit. - Page 5 1 General 1.1 Arc protection unit VAMP 121(D) Figure 1.1-2 Arc protection unit VAMP 121D V121/EN M/A017...

Page 7: Unit Configuration
2 Unit configuration Unit configuration During the configuration stage user has to determine the VAMP 121(D) functionality. The amount of used arc sensors is configured by moving the install dipswitches to “ON” position. During the configuration stage the user must configure all the following dipswitches. - Page 8 2 Unit configuration Figure 2-1. VAMP 121(D) dipswitch operations Dipswitches 6-8 (Code switches, see Figure 2-1): When switch nr 8 is OFF, the binary input (X2:7(-), X2:8(+)) has a blocking function, see switch nr 5. In the ON position the binary input has a reset function, see switch nr 1.

Page 9: Sensors
3 Sensors 3.1 Arc sensor VA 1 DA Sensors 3.1. Arc sensor VA 1 DA The arc sensor is a light sensitive element, which is activated by strong light. Arc sensors should be mounted in the switch-gear cubicles, in such a way that the light sensitive part (see Figure 3.1-2) covers the protected area as completely as possible. -

Page 14: Outputs
6 Connection examples 6.1. Outputs The VAMP 121(D) unit has an integrated relay output (X2-15,X2- 16) for tripping of the circuit-breaker. Furthermore, one binary output is available (+24V dc) X2-9 (-) X2- 10(+), which becomes inactive (0V) on internal fault (SF) and / or on tripping (configurable). -
Page 15: Inputs
6 Connection examples 6.2 Inputs 6.2. Inputs VAMP 121(D) has 10 arc sensor inputs X1:1-20, and one connection for a portable arc sensor (VA 1 DP). All these inputs have continuous self-supervision. Furthermore, one binary input is available for blocking of the output relay e.g. -
