AR
If a rectifier restarts for any reason it will issue a signal to all
other rectifiers to restart.
ACF
AC Fail is a contact closure between ACF and RTN (pin 16)
indicating to the controller that the rectifier ac source voltage has
fallen below approximately 170 vrms or the rectifier input fuses
have operated.
BAT
The -48 volt dc plant voltage is required on pin 14 to power the
CH, EQ, HV, and OTR alarm circuits in the rectifier. In ECS
battery plants, the -48-volt source is protected by a 1-1/3 ampere
fuse located on the LVD/R circuit board.
CH
Controller Handshake is a contact closure between CH and RTN
(pin 16) originating in the controller. This connection disables
the rectifier's internal high voltage shutdown circuits and allows
the system to rely on the controller's high voltage shutdown
circuits instead.
EQ
Equalize is a contact closure between EQ and RTN (pin 16)
originating in the controller, which forces the rectifier into
equalize mode.
