28 Operation
UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
Local/remote high voltage shutdown reset
The rectifier may be reset from an HVSD condition locally, by resetting the
AC circuit breaker (if so equipped), the associated AC breaker on the
distribution panel, or remotely by applying a ground signal at the HVSDR
input of the rectifier provided:
• the 'TR' lead is not activated
• the 'AC' (optional) and 'DC' breakers are closed
Remote equalize control
The rectifier is equipped with remote equalize control. This function is
operated by applying a remote ground signal (BAT POS) and returns to
normal (Float) operation upon removal of the signal.
Signal connections
The interface connector located at the rear of the rectifier provides control,
alarm and monitoring signals. The control inputs are activated by a ground
(BAT RTN) signal. The alarm contacts are extended by relays and are
isolated from each other, and from the rectifier chassis. All contacts are rated
60 V DC and 0.5 A.
