The XW SCC starts up in sleep mode and waits for a short period to determine
that the input voltage is greater than the output voltage. The LCD indicates the
XW SCC mode or any error conditions that may be present (see “Viewing
Operating Status” on page 4–2). After the input voltage exceeds the output
voltage by the required margin for 10 seconds, the unit begins operating.
Commissioning Multiple Units Without a System Control Panel
When commissioning several XW SCCs on the same Xanbus network, care must
be taken to set a unique device number and the correct battery connection for each
unit. The connection is important to define so that system totals and other related
information are displayed accurately on each unit’s LCD.
Once the first unit is configured, you can copy that configuration to all other units
by following the “Copy Config?” prompt on the LCD.
Settings that are copied from one unit to another:
•
Battery Type
•
Battery Amp Hour Capacity
•
Max Charge Rate/Current Limit
•
Charge Cycle
•
Recharge Voltage
•
Max Absorption Time
•
Default Battery Temperature
•
Nominal Battery Voltage
•
DC Out Connection/Battery Bank
•
Custom Battery Settings (if Custom Battery type selected):
•
Equalize Support
•
Equalize Voltage
•
Bulk Voltage
•
Absorption Voltage
•
Float Voltage
•
Battery Temperature Compensation
To commission multiple XW SCCs:
1. Close the DC disconnect or use a selector switch to apply battery power to all
of the XW SCCs at the same time.
The LCD on each unit displays the two startup screens in sequence, as shown
in Table 2-5, followed by a prompt screen for you to set the device number.
2. On all the charge controllers, set the device number to a value other than its
default value of 00. No two charge controllers can have the same device
number. The device number can be set to any number between 01 and 31. For
the first XW SCC, 01 is recommended. If you have two charge controllers,
simply set them to 01 and 02.
