Factory settings
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.
7.1.1.
Configuration during commissioning
The configuration and settings of the over-, under-, residual
voltage and frequency relay VAMP 135 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.
Selection of protection mode in menu U SCALING/U
mode
2.
Scaling of the rated values of the phase voltage
transformers in menu U SCALING
3.
Scaling of the rated values of the residual voltage
transformer U
0
SCALING
4.
Setting the adaptive frequency fn.
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.

SETTING and f SETTING menus, see Chapter 5.3.
7.
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.
8.
Configuration of the blocking matrix (BLOCKING menu),
see Chapter 5.6.
