Start-up
22
The start-up should be done in accordance with
the following instructions and advice. Checks 1
and 2 have to be done before the auxiliary power
supply is connected.
1. Voltage ranges of the binary inputs
Before connecting a voltage to input channels
1...14, check the operative voltage range of the
inputs. The voltage range, U
front panel of the control module. See also
chapter "Technical data".
2. Auxiliary supply voltage
Before switching on the auxiliary supply volt-
age, check the input voltage range of the power
supply module. The voltage range, U
marked on the front panel of the control mod-
ule. See also chapter "Technical data".
3. Setting of the control module SPTO 6D3
All the nonvolatile EEPROM parameters have
been given default values after factory testing.
The default parameters are explained in the
manual of the control module SPTO 6D3.
If the default parameters are not satisfactory, the
following parameters can be set:
- Configuration; a user defined configuration
- Interlocking; a user defined interlocking
- OPEN and CLOSE outputs; pulse lenghts
- Auto-reclosing; auto-reclose sequence, dead
times, reclaim time
- Measurements; ratio of primary current and
voltage transformers, settings for activ and
reactive power measurement, settings for en-
ergy measurement
- Input channels 8...17; settings for polarity
and output activation
- Event reporting; event masks, event delay
times
The parameters can be set via the front panel RS
232 connection or the rear panel RS 485 con-
nection using the SPA protocol. Instructions are
given in the manual of the control module
SPTO 6D3.
4. Settings of overcurrent and earth-fault mod-
is marked on the
At the factory the switches of the overcurrent
aux
and earth-fault modules have been given default
values, see chapter "Intermodular control signal
exchange". If auto-reclose functions or blockings
are used for the relay modules, check the posi-
tions of the SGB switches on the PC boards of
the modules SPCJ 3C3 and SPCS 3C4.
The front panel potentiometers of the protec-
is
tive relay modules are set in the middle position
aux
and all the front panel switches SG1 are turned
off. The functions of the front panel switches of
the overcurrent and earth-fault relay modules
are explained in the manual of the overcurrent
relay module SPCJ 3C3 and in the manual of
the directional earth-fault relay module SPCS
3C4.
