Only “ON” and “STANDBY”
can be used with ope.

s stands for shelf number (1, 2, or 3)
r stands for rectifier number (1 to 5)
Individual Rectifier State: When requested, shows the state of the individual
rectifiers. Note that the rectifier numbering starts from the left-most position of the
master shelf (shelf number 1.)
When obtaining individual rectifier status information, the following information may
be transmitted:
• ON: Rectifier operating normally. User may use ope to turn ON a rectifier in standby.
• OFF: Rectifier has been shutdown due to hardware failure.
• STANDBY: User has inhibited the rectifier's output voltage. User may use ope to
place a rectifier into a standby condition.
• MISSING: An acknowledged rectifier has been removed.
• VACANT: Rectifier has not been installed in that position.
Rectifiers may also be put in standby; however, the ability to place rectifiers in
standby requires some backup plan to take the rectifier out of standby automatically
under a low voltage condition. The battery on discharge (BOD) threshold is used as a
rectifier-on voltage threshold. In other words, when the plant voltage dips below the
BOD threshold, the controller turns on all rectifiers that are in standby.
Individual Rectifier Current: When requested, shows the current output from an
individual rectifier.
