Commissioning Procedure - Rectifier RT9- 24V Installation, Operation And Technical Manual

Installation, Operation and Technical Manual
systems that are to be commonly commissioned that the PC option be used. The benefit
is that predetermined configurations can be stored on disk and easily downloaded to the
MCSU-4 at any time. It is assumed that the operator commissioning the system has
knowledge of programming system parameters.
The system parameters can vary widely depending on the system configuration and
battery requirements. It is advisable to consult the battery data sheets as a reference
when determining the system parameters to be programmed into the MCSU-4.

7.3.1 Commissioning Procedure

For system with batteries and load, the commissioning procedure is as follows:
 Make sure there is no load on the DC bus and that the batteries are disconnected.
 If necessary, set the DIP switches on the backplanes, starting with 1 and ending with
the highest number corresponding to the number of rectifiers in the system. The DIP
switches are ON when slid to the top, and LSB is at the right when viewing from the rear
of the magazine. Position #1 corresponds to 0000 0001, position #2 to 0000 0010 and
so on up to 15. #16 corresponds to 0001 0000, #17 to 0001 0001 and so on.
 Insert a rectifier into the #1 position in the system and turn the AC power on. The
rectifier should power up and start the MCSU-4.
 Using either the MCSU-4 front panel or a PC connected to the RS-232 serial port,
program all the MCSU-4 parameters according to the system requirements. Make sure
that the number of rectifiers in the system is correctly set.
 Set up any parameters necessary to operate auxiliary equipment such as Battery Cell
Monitor (BCM), Mains Monitoring Interface Board (MMIB), Site Monitor, etc.
 Put all the remaining rectifiers 'on-line', one at a time by inserting the rectifier into the
magazine and switching on the corresponding input AC breaker where necessary.
Check that each unit powers up and communicates with the MCSU-4.
determined by checking that the MCSU-4 has a message window corresponding to the
rectifier number similar to "SMR2 0A".
 With all rectifiers operating correctly, add a load to the system of at least 30% of the
rated system current.
 Check that the MCSU-4 is able to control current sharing between the units by reading
current of all SMRs' from MCSU-4 SMR menu.
 Increase the load to 100% and check that the rectifiers all share load current.
 Reduce the load to 75% and burn in for 24 hours.
 Remove the load. Clear Alarm Log.
 Check that the wiring polarity of the battery is correct for the system, and then connect
the batteries on-line via a fuse or circuit breaker. Allow to charge before bringing final
system on-line.

detailed section on MCSU-4.
