Rectifier Comms Lost Alarm

When a rectifier is removed (or a fault interrupts rectifier communications), the SC200 will
display an alert message and sound an alert alarm (if Audible Alarms are enabled). After the
Alarm Recognition Period, a Rectifier Comms Lost alarm will activate.

A Multiple Rectifier Comms Lost alarm will activate (after the Alarm Recognition Period) if
more than one rectifier is affected.
► To prevent a Rectifier Comms Lost alarm when a rectifier is removed
Press any key within the Alarm Recognition Period, to cancel the alert.

Rectifier Shutdown

Rectifier shutdown can be disabled, controlled manually, or controlled automatically based on
the total rectifier load current (see Load Based Rectifier Shutdown on page 35).
► To disable Rectifier Shutdown
Use the SC200 keypad to go to: Rectifiers > Settings (tab) > set Rectifier Shutdown to
Disabled.
Or, in DCTools/Web go to: Rectifiers > Configuration> set Shutdown to Disabled.
Manual Rectifier Shutdown
► To shut down a rectifier
In DCTools/Web go to: Rectifiers > Configuration.
Set Shutdown to Manual.
In the Rectifiers table select the Shutdown check box (DCTools) or click Shutdown (Web).
The rectifier will shut down and the yellow LED will be on.

This function will normally only be used for testing purposes. When the testing is complete, set
Shutdown back to its previous setting (Disabled or Automatic).
Rectifier Restart
► To restart all shutdown rectifiers
Use the SC200 keypad to go to: Rectifiers > Rect. Settings (tab) > Restart All Rectifiers.
Or, in DCTools/Web go to: Rectifiers. Click Restart All.
► To restart individual rectifiers
In DCTools/Web go to: Rectifiers.
For each rectifier clear the Shutdown check box (DCTools) or click Startup (Web).
The rectifier(s) will then resume normal operation.

The SC200 will restart any shutdown rectifiers if: ac has failed, or more than one rectifier has
failed, or the bus voltage is below the Low Load threshold, or Rectifier Shutdown is set to Disabled,
or Rectifier Shutdown is set to Automatic.
