Galaxy Rack-Mounted Vector Controller J85501M-1
2 - 8 Product Description Issue 2 January 2008
BUJ1 Power, Sense
and Shunt
Connections
Power and other primary signal connections from the system
(factory wired in FMS). BUJ/Vector Controller power input
connections are not polarity sensitive, so the BUJ and controller
boards will operate regardless of BAT and DG polarity.
However, the operation of alarms and Vsense inputs are
affected, and the following guidelines should be used.

BAT: Connection to the battery discharge bus for controller
power, and fused through on-board F1. It is +24V for the GCM2,
and -48V for the GCM3. BAT input is typically the bus in which
circuit breakers and fuses are installed for distribution, and
therefore the alarm input potential. It is the ungrounded side of
the dc bus. For applications where this connection is made
outside of the frame/bay, this lead should be fused with a 3 to 5
amp fuse.
DG: Connection to battery return (discharge ground) bus. DG
provides the return for BAT (controller power) and ABS loads.
Connections are available on TB2 pins 11 and 12 on the alarm
board, and P5 pin 1 on the BUJ. DG input to the BUJ must be the
bus voltage opposite to the alarm inputs (BAT) bus. It is
connected to the grounded side of the dc bus.
SHUNT1+, SHUNT1-, SHUNT2+, SHUNT2-: Shunts must be
rated for 50mv full scale. The BUJ1 does not require series
impedance in these leads for circuit measurements. However,
the leads should be fused protected (1A or less) at the shunt prior
to sending the signal to the J85501M-1. The circuit can handle
the standard Lineage Power 100K 1% resistors in series with the
shunt which can also be used to limit the current.Shunt
