Commissioning - Test With No Power, No Sync - ABB DS1 Installation And User Manual

Suggested electrical diagram for operation of the machine in local and manual mode
The wiring must be made in compliance with the official circuit
diagram.
Once the wiring has been completed according to the DS1
auxiliary circuit diagram, use of pushbuttons and all the inter-
faces to be used for commissioning and maintenance will be
available.
To prevent the Binary Output from being
damaged, check the electrical characteristics
of the contact before sizing lamp power
consumption. If power consumption will be
higher, a relay can be used to replicate the
DS1 BO contact.
Use of an ADD-ON control panel can be helpful but wiring of
DS1 to the remote control room and/or the LV compartment
must be checked very carefully during the integration work to
make sure that it is correct before the apparatus is put into
service.
7.5 Commissioning - Test with no power,
no sync
If the ADD-ON panel panel is used for integration and test-
ing, remove all connectors with wires routed from the substa-
tion (commands, signals, status and alarms) from the terminal
boards.

Figure 25. Example of an electrical interface
Connect the connectors of the ADD-ON control panel in the
same corresponding positions.
The only connections that must remain are the two Power Sup-
ply wires (Terminal boards 1 (+) and 2 (-)).
Make sure that terminals 10 and 20 are linked with a short wire
so as to provide the Interlock command.
Install all the interlocks switches required to coordinate the
power plant in order to obtain all the correct interlock hier-
archy/levels. Take care of the interlock loop when the system
is de-energized and or maintenance/commissioning must be
performed (operations are inhibited when DS1 is opened).
Turn on the power supply
Wait a about 1 minute to allow the capacitor to reach a full
charge.
DS1 requires additional time to fully check its integrity (board
diagnostics, motor diagnostics and capacitor diagnostics.
The Key-switch on the ADD-ON control panel must remain in
the CCW position (upstream CB binary input not excited).

Do not touch DS1 when it is supplied. Its
internal capacitor storage reaches 350VDC
and even if the wiring is insulated, the
internal supply can represent an electrical
hazard especially if the system functions in a
faulty way.
