ETR/ETRR: A closure on this pair causes the controller to Terminate
(TR) all rectifiers. When this circuit again opens, the sequencing of the
plant rectifiers begins in the manner configured in software. This
ETR/ETRR signal may be obtained from auxillary contacts of the AC
Power Transfer device or may optionally come off of contacts of an AC
relay sensing the rectifier AC input bus.
RO/ROR: (Reserve Operation) A closure on this pair informs Galaxy
that the reserve AC generator is suppling the load and permits Galaxy to
hold rectifiers which have been so configured off line while this
condition exists. This feature is primarily designed for use at locations
where the reserve AC power source is not sufficiently sized to support
all the plant rectifiers.
Even without the Intelligent Control board, the Basic Galaxy can accept
ground signals onto TR1 to TR4 (BJT TB3-8 to -11) from an external
device to control sequencing of plant rectifiers in groups as follows:
TR1 G01, G02, G09, G10, G17, G18, G25, G26, G33, G34, G41,
G42, G49, G50, G57, G58
TR2 G03, G04, G11, G12, G19, G20, G27, G28, G35, G36, G43,
G44, G51, G52, G59, G60
TR3 G05, G06, G13, G14, G21, G22, G29, G30, G37, G38, G45,
G46, G53, G54, G61, G62
TR4 G07, G08, G15, G16, G23, G24, G31, G32, G37, G40, G47,
G48, G55, G56, G63, G64
Refer to Figures 3-5 and 3-15.
