Tyco Electronics Galaxy SC Controller J85501F-1

is known as the Rectifier On Delay (ROD). The default value for the
ROD is 10 minutes. Thus, when the plant voltage drops below the ROT
value for the ROD delay, all rectifiers in standby mode for any reason,
except Tyco Electronics J874 series rectifiers with active Circuit
Breaker Alarms, will turn on.
Invalid Engine
Signals
The Galaxy SC monitors signals from the external engine sequencer
(TR1, TR2, TR3, and TR4), as well as the ETR sequence signal. If all
four TR signals are simultaneously activated, or the ETR signal is
activated longer than the user programmable Engine Time-Out
threshold, then the Galaxy SC assumes there is a problem with the
source of the signals and all the rectifiers are turned back on in an
orderly manner. The Engine Time-Out Threshold is set to 30 minutes as
a default, and can be delayed up to 60 minutes. Zero minutes as a
threshold indicates that this time-out value is to be ignored.
