3.0 COMMISSIONING
This chapter describes commissioning a Power System. Individual system settings can vary widely so it is important that those
performing the commissioning fully understand the system at hand. Modify these procedures as needed to accommodate the installed
equipment and your company’s commissioning procedures.
3.1 PREPARATION
Perform the following steps prior to commissioning a Power system.
1.
Gather system wiring diagrams, battery data sheets, and other site documentation for ready reference should it be needed.
2.
Complete all installation steps. Refer to Chapter 2 Installation, as necessary.
3.
Review the steps in Section 3.2 Commissioning a System.
4.
Become familiar with operator panel LEDs, front panel displays, push buttons, and menus by reading Chapter 4 Configuration
and Operation.
5.
Start up configuration parameter values:
•
Battery String Connected to Plant – The string will power the SCU prior to starting the first Rectifier, assuming at least a
minimal battery charge, and the SCU 2-line display and status LEDs will be active. You may then use the operator panel to
change many of these default parameter values to accommodate the application. See Table 4-1 for a list of default parameters
and values.
•
No Battery String Connected to Plant– When the first Rectifier starts and powers the SCU, the SCU will load a default plant
configuration. You may then use the operator panel to change many of these default parameter values to accommodate the
application. See Table 4-1 for a list of default parameters and values.
Alternatively, edit the configuration parameter values, or load a new configuration, from a PC connected to the USB port on the
plant operator panel or from a PC connected to an Ethernet network (an IP address must be entered). The PC must be running the
optional SageView
™
plant monitor software.
6.
Become familiar with the Rectifier LED codes in Section 6.3 Troubleshooting.
7.
The system may be commissioned with the battery string(s) connected or disconnected, however, consider the configuration
statements in paragraph 5 above.
8.
Finally, perform the steps in Section 3.2 Commissioning a System.
3.2 COMMISSIONING A SYSTEM
This procedure assumes a newly installed system that includes connected batteries and loads.
1.
Before applying AC power, check that:
•
All AC input cables are connected to the correct terminals and that connections are tight
•
All load (supply and return) and battery cables are correctly connected and that connections are tight; check polarity as well
•
All alarm wiring is correct and tight, and that alarm annunciators function
•
The System housing and return bus are connected to the site earth ground
2.
Read the operator panel display and note LED indications.
•
If a connected battery string is supplying sufficient power to the SCU, the operator panel 2-line display will be active and
show System voltage and current. The LEDs should also be active with an alarm showing since all Rectifiers are Off. The
factory-installed or uploaded configuration will specify the number of Rectifiers. See Table 4-1 for default parameters and
values.
•
If a battery string is not connected or the string cannot supply sufficient power, the SCU will not be operating. There will be
no operator panel display or lighted LEDs until a Rectifier is started later in this Section.
