LBRS Test
The LBRS Test function will cycle the rectifiers once.
LBRS Test is not available if LBRS is Disabled, Suspended or Inactive. If Battery Test Before
LBRS is enabled then a Battery Test will be performed (see details on page 25).
► To start an LBRS Test
Configure and Enable LBRS (see details on page 25).
In DCTools go to: Rectifiers > Load Based Rectifier Shutdown > LBRS Test.
Set LBRS Restart After Test to the required setting.
When the test is completed or stopped normal LBRS operation will start after this delay.
When LBRS is Active, click Start.
LBRS Test will cycle the available rectifiers with a cycle time of 90 seconds until all rectifiers
have been shutdown and restarted.
If required, click Stop to end an LBRS Test before all rectifiers have been shutdown and
restarted.
LBRS Suspend
If required, when LBRS is active it can be temporarily suspended for system maintenance or
other reasons.
LBRS Suspend is not available if LBRS is Disabled, Testing or Inactive.
► To temporarily suspend LBRS
In DCTools go to: Rectifiers > Load Based Rectifier Shutdown > LBRS Suspend.
Set LBRS Restart to the required setting.
Normal LBRS operation will start after this delay.
When LBRS is Active, click Suspend.
LBRS will be suspended and all shutdown rectifiers will restart.
Normal LBRS operation will resume automatically after the LBRS Restart delay. Or, click
Resume.
LBRS is automatically suspended if the Battery Fuse Fail alarm is active.
Auxiliary Temperature Shutdown
This feature requires a second temperature sensor connected to the I/O board.
All rectifiers can be shutdown if the temperature measured by the Auxiliary Temperature
sensor is outside a configured range.
If a sensor used for Auxiliary Temperature Shutdown becomes faulty or disconnected this
may cause an unnecessary rectifier shutdown.
See also LVD Auxiliary Temperature Disconnect on page 31.
