► To enable Load Based Rectifier Shutdown
 In DCTools go to: Rectifiers > Load Based Rectifier Shutdown
 Ensure that Rectifier Start Up Delay is less than 30 seconds. See information on page 23. LBRS
will not function correctly if the start up delay is more than 30 seconds.
Information
The following information is available about Load Based Rectifier Shutdown.
Parameter
Description
Where to find:
State
Disabled: LBRS is not enabled.
Inactive: LBRS is enabled but not active.
Active: LBRS is operating.
Testing: See details on page 26.
Suspended: See details on page 26.
Not enough Rectifiers: See Redundancy setting on page
25.

Redundancy
If N plus 0 rectifier redundancy is selected, then only
sufficient rectifiers to supply the load will be on. If N
plus 1 rectifier redundancy is selected, then one
additional rectifier will always be on.
Rectifier Cycle
High Threshold
LBRS restarts rectifiers if the load is more than this
percentage of the total rectifier capacity.
Rectifier Cycle Low
Threshold
LBRS shuts down rectifiers if the load is less than this
percentage of the total rectifier capacity.
Battery Test Before
LBRS
See details on page 25.
Restart All
Rectifiers
Press to temporarily restart all rectifiers shut down by
LBRS.
 Disable LBRS to permanently restart all
rectifiers.
Battery Test Before LBRS
If LBRS and Battery Test Before LBRS are Enabled then, at startup of the SC100, a Battery Test will
be started and LBRS will be Inactive. LBRS will only become Active if the Battery Test is
successful.
If the Battery Test fails then LBRS will remain inactive until a successful Battery Test is completed
(or Battery Test Before LBRS is Disabled).
