Table 27 Contactors Configuration
ID1-6
Associates the ID numbers set on the distribution monitoring boards
(NE872/QS871) to one of four independent set of contactor controls.
These contactor controls are: LVBD (Low Voltage Battery Disconnect), LVLD1
(Low Voltage Load Disconnect 1), LVLD2 (Low Voltage Load Disconnect 2),
and LVLD3 (Low Voltage Load Disconnect 3).
The controller has assigned each unique board ID number as follows: ID1 to LVBD, ID2 to LVLD1, ID3 to
LVLD2, and ID4 to LVLD3. Note: the text description used for the disconnect such as “LVLD1” can be
renamed using the remote interfaces. Each of these assignments has its own unique programmable
parameters described next. ID5-ID8 have been assigned to NONE. Selecting NONE removes the ability of
that particular distribution control board to control and external LVD.
Disconnects
This section of the configuration menu contains the parameters associated with the individual function
assignments made in the previous section. Each LVD type (LVBD and LVLD1-3) can individually be enabled or
disabled. Only the LVBD and LVLD1 are Enabled from the factory. The LVD’s disconnect and reconnect
method of operation used by the controller can be configured for each assignment. The method of
disconnect or reconnect can be based on the traditional means of reaching a system bus voltage threshold
(Voltage) or based on both reaching the system bus voltage threshold and an elapsed time from once the
system has been placed on discharge (BD) and at least two or more rectifiers are reporting AC failures
(Voltage/Time). The same Voltage and Voltage/Time mode of operation can also be selected for
reconnecting LVDs. In this case the elapsed time configured is the time from once the reconnect voltage
threshold has been reached. Note: selecting None for a reconnect mode will require manual intervention to
shut the contactor. Selecting None for the disconnect mode will not allow a LVD to open. The controller has
factory defaults of the following:
