Start-Up - ABB SPAC 536 C User Manual

Start-up

24
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 active 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-
At the factory the switches of the protection
relay modules have been given default values,
see chapter "Signal diagram". In the combined
overcurrent and earth-fault relay module SPCJ
4D24 all current and time settings are given
their minimum values. The checksums of the
is marked on the default settings of the different switchgroups of

During the factory tests the setting knobs of the
directional earth-fault relay module SPCS 3C4
are set in their middle position and the switches
of switchgroup SG1 are set in position 0.
When auto-reclose functions or external block-
ing signals are to be used the positions of the
switches of switchgroups SGB, SGR1...3 and
SGF2 of the overcurrent and earth-fault relay
module SPCJ 4D24 are to be checked. So are
also the switches of switchgroup SGB of the
directional earth-fault relay module SPCS 3C4.
The settings of the overcurrent and earth-fault
relay module can be given with the push buttons
on the front panel of the relay module. The
settings can also be given via the RS 232 port on
the front panel or via the RS485 port on the rear
panel of the feeder terminal.
Full information on the functions of the switches
of the relay modules are given in the manuals of
the combined overcurrent and earth-fault relay
module SPCJ 4D24 and the directional earth-
fault relay module SPCS 3C4.
