When delivered from the factory, the relay has been given
factory default settings or settings defined by the customer. The
actual configuration can be read from the workshop test report
or from the final test report

Configuration during commissioning
The configuration and settings of the overcurrent and earth-
fault relay VAMP 130 is defined and checked during
commissioning in accordance with the instructions given in
Chapter 5 of this manual, for example in the following order:
1. Scaling of the rated values of the current transformer in
menu IL SCALING
2. Scaling of the rated values of the residual current
transformer Io SCALING
The scaling is done in the software block of the measured
signals, Figure 7.1.1-1. Thus the scaling affects all the protection
functions.
Figure 7.1.1-1 Principle for scaling the measured values of the VAMP 130
relay.
3. Activation of the desired protection functions, ENABLE
menu, see Chapter 5.2.
4. Setting values of the protection functions, see Chapter 2 in
the Technical description.
5. Configuration of the starting and tripping signals of the
protection stages to the desired output relays and the LED
indicators (DOUT menu), see Chapter 5.5.
6. Configuration of the blocking matrix (BLOCKING menu),
see Chapter 5.6.
